Background: Frailty is a common geriatric syndrome related to multiple adverse outcomes. Sex differences in its prevalence and impact on mortality remain incompletely understood. Methods: This study was conducted with data from the I-Lan Longitudinal Aging Study, in which community-dwelling subjects aged > 50 years without coronary artery disease or diabetes were enrolled. Sex disparities in phenotypically defined frailty and sex–morality predictor interactions were evaluated. Sex- and frailty-stratified analyses of mortality were performed. Results: The sample comprised 1371 subjects (51.4% women, median age 61 years). The median follow-up period was 6.3 (interquartile range, 5.8–7.0) years. The frailty prevalence did not differ between men (5.3%) and women (5.8%). Frail individuals were older and less educated and had poorer renal function than did non-frail individuals. Body composition trends differed between sexes, regardless of frailty. Relative to non-frail men, frail men had significantly lower body mass indices (BMIs; 24.5 vs. 23.4 kg/m2, p = 0.04) and relative appendicular skeletal muscle masses (7.87 vs. 7.05 kg/m2, p < 0.001). Frail women had significantly higher BMIs (25.2 vs. 23.9 kg/m2, p = 0.02) and waist circumferences (88 vs. 80 cm, p < 0.001) than did non-frail women. Frailty was an independent mortality predictor for men only [hazard ratio (95% confidence interval) = 3.395 (1.809–6.371), psex–frailty interaction = 0.03]. Conclusion: Frailty reflected poorer health in men than in women in the present cohort. This study revealed sex disparities in the impact of frailty on mortality among relatively healthy community-dwelling older adults. [ABSTRACT FROM AUTHOR]

Objectives: As the psychosocial competence, personal mastery helps individuals to cope with stressful life events, and this study aims to examine impacts of declines in personal mastery on healthy aging among community-dwelling middle-aged and older adults using a nationally representative cohort. Methods: Data from 648 study participants in the Social Environment and Biomarkers of Aging Study (SEBAS) were retrieved for analysis. All participants were divided into four groups based on their baseline and changes of personal mastery (measured by the Pearlin mastery score) during the 6-year follow-up. Multivariate logistic regression models were adopted to examine associations between declines in personal mastery and indicators for healthy aging (declines in self-perceived mobility, physical function (activities of daily living (ADLs) and instrumental activities of daily living (IADLs)), cognitive function and depressive symptoms). Results: After adjustments for demographics and comorbidities, those with declines in personal mastery were associated with greater risks of declines in self-perceived mobility (adjusted odds ratio (aOR) 1.50 [95% confidence interval 1.01–2.22], p < 0.05). Although the point estimate in the unadjusted models indicated similar associations between declines in personal mastery and declines in ADLs, IADLs, cognitive function or depressive symptoms, these outcomes did not reach statistical significance in the adjusted model. Conclusions: Declines in personal mastery were negatively associated with indicators related to healthy aging (particularly locomotion) in a 6-year follow-up. Further investigations are needed to explore the effects of preventing declines in personal mastery in promoting healthy aging over time. [ABSTRACT FROM AUTHOR]

Objectives: Despite the recognized impact of intrinsic capacity (IC) impairment on healthy aging, international comparisons in different sociocultural contexts are scarce. This study aimed to compare IC impairment among community-dwelling older adults in Japan and Taiwan to explore the context of healthy aging in different countries. Design: Comparative observational study. Setting: National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA) in Japan and Longitudinal Aging Study of Taipei (LAST) in Taiwan. Participants: 794 individuals (age range, 60.0–86.5 years) from NILS-LSA and 1,358 (60.0–96.7 years) from LAST. Measurements: IC impairment was evaluated across the domains of locomotion, cognition, vitality, sensory capacity, and psychological well-being. Participants were categorized as having impaired IC or healthy. We investigated associations between IC impairment, falls, and all-cause mortality. Results: IC impairment was present in 54.9% and 37.3% of participants in the NILS-LSA and LAST cohorts, respectively. Male NILS-LSA participants with impaired IC (odds ratio [OR]:1.50, 95% confidence interval [CI]:1.03–2.20), with hearing loss (OR:1.98, 95% CI:1.00–3.90) were more likely to fall. In LAST, impaired locomotion (OR:2.14, 95% CI:1.46–3.14) increased the risk of falls. Men with impaired IC (hazard ratio [HR]; 2.14, 95% CI.10–4.15) and visual impairment (HR:2.21, 95% CI:1.15–4.25) and women with impaired psychological well-being (HR:4.94, 95% CI:1.28–18.97) in the NILS-LSA cohort had greater risk for all-cause mortality; however, this was not shown for LAST participants. Conclusion: The prevalence and distribution of IC impairment and associated biomarkers differed significantly between participants in Japan and Taiwan. However, the associations with adverse outcomes remained similar, emphasizing the need for tailored interventions for healthy aging. [ABSTRACT FROM AUTHOR]

Background: Social isolation is a pervasive and debilitating condition that has adverse prognostic impacts. This condition often co-occurs with other geriatric syndromes, further exacerbating negative health outcomes. Given these considerations, the present study aims to elucidate the roles of social isolation in older adults with anorexia of aging and/or sarcopenia with respect to long-term mortality using a nationally representative cohort study. Methods: Data were obtained from the Taiwan Longitudinal Study on Aging (TLSA), with a sample size of 3,762 study participants aged 50 years and older. Data from 1999 (wave 4) to 2015 (wave 9) were analyzed. The TLSA questionnaire was used to define social isolation, anorexia, and sarcopenia. Logistic regressions were employed to explore the associations between social isolation, anorexia, and sarcopenia. The Cox proportional hazard model was utilized to examine the synergistic effects of social isolation and anorexia or sarcopenia on 16-year all-cause mortality. Results: After controlling for demographic information and comorbidities, older adults with social isolation were significantly associated with anorexia (adjusted odds ratio [aOR] 1.46 [95% confidence interval: 1.00–2.12, p=0.0475]) and sarcopenia (aOR 1.35 [95% CI: 1.12–1.64, p=0.0021]). Furthermore, the synergistic effects of social isolation with anorexia (aOR 1.65 [95% CI: 1.25–2.18, p=0.0004]) or sarcopenia (aOR 1.65 [95% CI: 1.42–1.92, p<0.0001]) were both significantly associated with higher risks of all-cause mortality, while social isolation alone revealed borderline statistical significance. Conclusions: Our findings indicate that social isolation is closely linked to anorexia and sarcopenia among middle-aged and older adults. Additionally, social isolation significantly exacerbates the long-term mortality risk associated with anorexia of aging and sarcopenia. However, social isolation alone appears to have borderline long-term mortality risk in this cohort. These findings underscore the importance of addressing social isolation in older adults with anorexia and/or sarcopenia to optimize their health outcomes and mitigate long-term mortality risk.

Objectives: To evaluate the associations between cardiovascular disease (CVD) risk burden (estimated by the World Health Organization (WHO) algorithm) and cognitive impairments (e.g., incident dementia, global and domain-specific impairments) among CVD-, dementia- and disability-free, community-dwelling middle-aged and older adults during an 8-year follow-up. Design: A community-based longitudinal cohort study. Setting: Yuanshan township in Yi-Lan County, Taiwan. Participants: A total of 889 community-dwelling residents aged 50 years or older. Measurements: Age, sex, educational level, employment status, alcohol status, body mass index, physical activity, gait speed, depressive symptoms, WHO region-specific CVD risk scores (10-year CV risk, low: <10% vs. moderate-to-high: ≥ 10%), Chinese version of the Mini-Mental State Examination (MMSE), verbal memory by the delay-free recall in the Chinese Version Verbal Learning Test (CVVLT), language function by the Boston Naming Test and the category (animal) Verbal Fluency Test, visuospatial function by the Taylor Complex Figure Test, executive function by the digit backward and the Clock Drawing Test. Results: Compared to those with low CVD risk, middle-aged and older adults with moderate-to-high CVD risk were at greater risk for cognitive impairments with respect to the MMSE (adjusted odds ratio (aOR) 1.60 [95% confidence interval (CI) 1.19–2.15], P=0.002), verbal memory (aOR 1.97 [1.43-2.70], P< 0.001) and language (aOR 1.99 [1.46–2.70], P< 0.001), as well as incident dementia (aOR 2.40 [1.33–4.33], P=0.004). After adjusting for all covariates, CVD risk was not associated with other domains of cognitive impairment. Conclusions: Among healthy, community-dwelling, middle-aged and older adults, those with moderate-to-high cardiovascular risk burden were significantly associated with incident dementia and global and domain-specific cognitive impairments (verbal memory and language), which suggests the existence of a relationship between early cognitive deficits and CVD risk burden. Further studies are needed to elucidate the pathophysiological mechanism of the link between CVD risk burden and cognitive impairment. [ABSTRACT FROM AUTHOR]

Aims Frailty substantially increased the risk of adverse clinical outcomes, which was also critical in diabetes management. This study aimed to investigate the interrelationships between the age of onset, frailty, anti-diabetic medications and clinical outcomes in people with diabetes mellitus (DM). Methods A total of 123,172 people aged 40 years and older who were newly diagnosed with DM were identified and categorised into four frailty subgroups (robust, mild, moderate and severe) based on the multimorbidity frailty index (mFI). Cox proportional hazards models were used to examine associations between frailty and clinical outcomes at different ages of DM onsets (40–64, 65–74, 75–84 and 85+ years). Outcomes of interest included generic outcomes (mortality and unplanned hospitalisation) and DM-related outcomes (cardiovascular disease-related mortality, major adverse cardiovascular events (MACEs), diabetes-related hospitalisation and hypoglycaemia). Results The proportion of frailty increased with age at diagnosis amongst people with incident DM and the mFI scores increased significantly during the 10-year follow-up. Amongst people with diabetes, those with mild, moderate and severe frailty were associated with greater risks of all-cause mortality (mild: adjusted hazard ratio (aHR) 1.69 [95% confidence interval (CI) 1.60–1.80], P  < 0.01; moderate: aHR 2.46 [2.29–2.65], P  < 0.01; severe frailty: aHR 3.40 [3.16–3.65], P  < 0.01) compared with the robust group. Similar results were found in unplanned hospitalisations, cardiovascular disease-related mortality, MACEs and hypoglycaemia. Conclusions Our study quantified the prevalence of frailty, captured its dynamic changes and examined its impacts on various clinical outcomes amongst people with diabetes at different ages at onset. Frailty assessment and management should be implemented into routine diabetes care. [ABSTRACT FROM AUTHOR]

Introduction: Cognitive impairment (COIM) is a major challenge for healthcare systems and is associated with an increased risk of adverse outcomes in older people visiting emergency departments (EDs). Owing to global aging, both cognitive screening and comprehensive geriatric assessment (CGA) application in ED settings are developing areas of geriatric emergency medicine. Meanwhile, the association between clinical outcomes of COIM; cognitive impairment, no dementia (CIND); and dementia in the ED could be better investigated. Our study aims to identify individuals with COIM from older patients in the ED via CGA and to describe the association of CIND and dementia with prognosis in ED visits. Methods: A prospective cross-sectional study was conducted in the ED of the Taipei Veterans General Hospital, a medical center located in Taipei, Taiwan, from August 2018 to November 2020. Patients aged ≥75 years with and without COIM were compared using data obtained from the CGAs conducted by trained nurses. Results: A total of 823 older patients were enrolled in the study and underwent CGA. Of these, 463 (56.3%) were diagnosed with COIM, of which 292 (35.5%) were diagnosed with dementia; and 171 (20.8%), CIND. Between the no-COIM and COIM groups, the COIM group had a higher rate of hospital admission (p = 0.002) and mortality at 3 months (p < 0.05). Among the no-COIM, CIND, and dementia groups, ED disposition (p = 0.001) and the rate of revisit/readmission (p < 0.05) showed significant differences. In particular, the dementia group had a significantly higher rate of revisit/readmission as compared to the CIND group among the three groups. Discussion/Conclusion: Older patients with COIM had a higher rate of hospital admission and mortality at the 3-month follow-up than older patients without COIM. Among the no-COIM, CIND, and dementia groups, patients with dementia had significantly increased risks of hospital admission and revisit/readmission. The early detection of COIM, and even dementia, could help ED physicians formulate strategies with geriatric specialists to improve mortality outcomes and revisit/readmission. [ABSTRACT FROM AUTHOR]

Background: Few studies have made longitudinal comparisons between frailty phenotype (FP) and frailty index (FI) changes. We aimed to investigate frailty status changes defined by FP and FI concurrently, and to compare the associated factors and incident disability among different combination of FI and FP trajectory groups.Methods: Data on respondents aged over 50 who completed the 1999, 2003 and 2007 Taiwan Longitudinal Study on Aging (TLSA) surveys (n = 2807) were excerpted. Changes of FI, FP and major time-dependent variables were constructed by group-based trajectory modeling. Logistic regression was used to investigate the associated factors and relationships with incident disability among different frailty trajectories.Results: We identified four FP trajectories - stably robust, worsened frailty, improved frailty, and stably frail and three FI trajectories - stable FI, moderate increase FI and rapid increase FI. Lower self-rated health, mobility impairment, and depressed mood were associated with unfavorable FP and FI changes (all p < 0.001). Regardless of FP trajectory groups, the moderate and rapid increase FI group had significantly more comorbidities than the stable FI group, and more visual, hearing, oral intake impairment, more difficulty in meeting living expenses, and poorer cognitive function in ≥65-year-olds (all p < 0.05). In addition, the worsened frailty, improved frailty, and stably frail groups had ORs for incident disability of 10.5, 3.0, and 13.4, respectively, compared with the stably robust group (all p < 0.01); the moderate and rapid increase FI groups had 8.4-fold and 77.5-fold higher risk than the stable FI group (both p < 0.001). When combining FI and FP trajectories, risk increased with FI trajectory steepness, independent of FP change (all p < 0.01 in rapid increase FI vs stable FI).Conclusions: Four FP trajectories (stably robust, worsened frailty, improved frailty, and stably frail) and three FI trajectories (stable FI, moderate increase FI and rapid increase FI) were identified. Lower self-rated health, mobility impairment, and depressed mood were associated with both unfavorable FP and FI trajectories. Nevertheless, even for individuals in stably robust or improved frailty FP groups, moderate or rapid increase in FI, either due to comorbidities, sensory impairment, cognitive deficits, or financial challenges, may still increase the risk of incident disability.

Background Longitudinal adverse outcomes are unclear among adults with diabetes according to the age of onset. Objective To investigate the longitudinal diabetes-related outcomes in adults with new-onset diabetes stratified by age. Design Retrospective cohort study. Setting Taiwan National Health Insurance Research Database claims data from 2000 to 2015. Subjects In total, 115,751 participants aged ≥40 years with new-onset diabetes in 2003 were recruited and stratified by the ages 40–64 (64.3%), 65–74 (21.2%), 75–84 (11.8%) and ≥85 years (2.7%) at the time of diagnosis. Methods Time-varying multivariate Cox proportional hazards model adjusted for covariates was used to examine the associations between the ages of the patients at diabetes onset and the outcomes of interest [all-cause mortality, cardiovascular (CV) mortality, major cardiovascular events (MACE) and hypoglycaemia] during a 10-year follow-up period. Results The results showed that compared with those patients aged 40–64 at diagnosis, patients with older-onset diabetes had significantly higher comorbidities (P  < 0.01) and a higher diabetes severity (P  < 0.01). Patients with older-onset diabetes had a higher risk of all-cause mortality [adjusted hazard ratio (aHR) 2.28, 4.48 and 10.07 in 65–74, 75–84 and ≥85 years old, respectively], CV mortality (aHR = 2.82, 6.06 and 15.91), MACE (aHR = 2.19, 3.01 and 4.15) and hypoglycaemia (aHR = 2.41, 3.59 and 4.62) than patients aged 40–64 during a 10-year follow-up period. Conclusions Patients with diabetes onset at an older age was associated with increased risks of all-cause mortality, CV mortality, MACE and hypoglycaemia after adjusting for the severity of diabetes and anti-diabetic treatment.

Background: Components of physical frailty cluster into subtypes, but it remains unknown how these might be associated with age‐related functional declines and multimorbidities. This study aims to investigated associations of physical frailty subtypes with functional declines and multimorbidity in a 10 year longitudinal cohort survey. Methods: Complementary longitudinal cohort study used group‐based multitrajectory modelling to verify whether frailty subtypes discovered in Taiwan are presented in another aging cohort, then investigated associations of these subtypes with cognitive decline and multimorbidity. Participants aged ≥50 years were recruited from the third to sixth waves (May 2002 to July 2010) of the National Institute for Longevity Sciences‐Longitudinal Study of Aging, in Japan. People with incomplete data, pre‐frail/frail status before their index wave, and those with incomplete data or who died during follow‐up, were excluded. Group‐based trajectory analysis denoted five established physical frailty criteria as time‐varying binary variables in each wave during follow‐up. Incident frailty was classified as mobility subtype (weakness/slowness), non‐mobility subtype (weight loss/exhaustion), or low physical activity subtype. General linear modelling investigated associations of these frailty subtypes with activities of daily living, digit symbol substitution test (DSST) and Charlson Comorbidity Index (CCI) at 2 year follow‐up. Results: We identified four longitudinal trajectories of physical frailty, which corroborated the distinct subtypes we discovered previously. Among 940 eligible participants, 38.0% were robust, 18.4% had mobility subtype frailty, 20.7% non‐mobility subtype, and 20.1% low physical activity subtype. People with mobility subtype frailty were older than those with other frailty subtypes or robust status and had higher prevalence of hypertension, diabetes, and heart failure. In the multivariable‐adjusted general linear models, mobility‐subtype frailty was associated with a significantly lower DSST score (point estimate −2.28, P = 0.03) and higher CCI (point estimate 0.82, P < 0.01) than the other groups. Conclusions: Mobility‐subtype frailty was associated with functional declines and progression of multimorbidity; the long‐term effects of physical frailty subtypes deserve further investigation.

The utilization of benzodiazepines (BZDs) and z-hypnotics has substantially increased with the aging of the population, but the risk of BZDs and z-hypnotics in the development of dementia remains a strong concern. This cohort study aimed to evaluate the risk of BZDs and z-hypnotics for subsequent dementia development with a special consideration of their half-lives and the concomitant use of these medications. People aged 65 years and older who were newly prescribed oral BZDs or z-hypnotics between 2003 and 2012 were identified from Taiwan's National Health Insurance Research Database. All BZDs were categorized as long-acting drugs (≥ 20 h) or short-acting drugs (< 20 h) for further comparisons, and data were collected on a quarterly basis, starting on the first date of drug prescription and ending on the date of death, occurrence of dementia, or end of the follow-up period (December 31, 2012), whichever came first. All dementia events except vascular dementia occurring during the follow-up period were identified. Among 260,502 eligible subjects, short-acting BZDs and z-hypnotics users were at greater risk of dementia than long-acting users [adjusted odds ratio (95% confidence interval) in short-acting BZD users, 1.98 (1.89-2.07); z-hypnotic users, 1.79 (1.68-1.91); and long-acting BZD users, 1.47 (1.37-1.58)]. In addition, subjects concomitantly using 2 or more BZDs or z-hypnotics had a higher risk of dementia than those who used 1 of these drugs (4.79 (3.95-5.81)). The use of BZDs and z-hypnotics was strongly associated with the risk of dementia development, especially the short-acting BZDs, z-hypnotics, and concomitant use of multiple agents. These findings deserve further interventional studies for clarification. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the effect of body weight, waist circumference and their changes on all-cause and cardiovascular mortality.Design: A nationwide population-based cohort studyParticipants: 627 community-dwelling older adults.Measurements: Participants were interviewed for demographic and anthropometric data collected. Blood were drawn for testing biochemistry data. Central obesity was defined as waist circumference is greater than 80 cm for women and 90 cm for men. Obesity, overweight, normal and underweight were defined as BMI ≥27 kg/m2, ≥24 kg/m2,18.5-24 kg/m2 and <18.5 kg/m2. Cox proportion hazard model was used to explore the impact of body weight and its change on mortality.Results: The distribution of weight changes and mortality was right skewed, but U-shape of waist change for all-cause mortality was observed. Compared to normal BMI at baseline, the association between underweight (HR: 1.7, 95% CI: 0.7-4.0), overweight (HR:0.7, 95% CI:0.4-1.2) and obesity (HR:1.3,95% CI:0.8-2.3) showed insignificantly associated with all-cause mortality. The HR of those weight loss >5% (HR: 1.7, 95% CI: 1.1-2.8) and waist decrease >5% (HR: 1.7, 95% CI: 1.0-2.8) were higher than those of stable weight/waist +/- 5% over a 6-year period. Compared to those stable weight/waist, the mortality risk was similar in those of weight gain or waist increase (HR 0.7,95%CI: 0.4-1.5 and HR:0.9, 95%CI:0.4-1.6).Conclusion: Weight loss and waist decrease were significantly associated with long-term mortality risk, a life-course approach for body weight management is needed to pursuit the most optimal health benefits for the middle-aged and older adults.

Aim The use of anticholinergic drugs had been strongly linked to adverse health outcomes among older adults, especially in cognitive impairment or dementia. The present study aimed to evaluate the cognitive decline related to the use of anticholinergic drugs among older men living in the veterans' homes in Taiwan. Methods This retrospective cohort study was a substudy of The Longitudinal Older Veterans study. A total of 274 residents living in four Taiwan veterans' homes and receiving two consecutive Mini-Mental State Examinations within the interval of 6 months from January 2012 to December 2014 were enrolled in the present study. The medication lists for all participants were reviewed by the same physician, and the anticholinergic properties of the individual medications were evaluated by using the Anticholinergic Cognitive Burden scale. Cognitive decline was defined as the decrease of Mini-Mental State Examinations scores during the study period. Results Overall, 139 persons (50.7%) had exposure to anticholinergic drugs at baseline (designated as AC[+]), and the most frequently used anticholinergic drugs were cardiovascular drugs (48.2%), antipsychotics (21.6%), theophylline (20.1%), antidepressants (12.2%), gastrointestinal drugs (11.5%) and antihistamines (8.6%). After adjusting for covariates, AC(+) participants had a significantly higher risk for short-term cognitive decline (OR 2.69, 95% CI 1.36-5.31). After excluding 30 participants using antipsychotics, non-antipsychotics AC(+)participants still had a significantly higher risk for short-term cognitive decline (OR 2.24, 95% CI 1.26-3.99). Conclusions Exposure to anticholinergic drugs significantly increased the risk for short-term cognitive decline among older men, and the adverse effects remained similar when antipsychotics were excluded for analysis. A further intervention study is required to evaluate whether reducing anticholinergic burden might improve cognitive function among older adults. Geriatr Gerontol Int 2017: 17 (Suppl. 1): 57-64.

Aim It has been reported that many people with dementia require hospitalizations. The objective of the present study was to determine predictive factors for hospitalizations in people with dementia. Methods A total of 70 individuals with dementia living in a veterans' home in southern Taiwan were consecutively enrolled. During prospective follow up, all hospitalization events were recorded. Results The mean age of residents with dementia was 86.1 ± 4.0 years, and the mean follow-up time for this population was 2.2 ± 1.1 years. Among individuals, 62.9% suffered from malnutrition or were at risk of malnutrition (minimal nutritional assessment-short form score ≤11), and 8.6% of individuals had a body mass index of <18.5 Kg/m2. There were 52 (74.3%) individuals who had previously fallen. Overall, 51 of 70 residents were hospitalized during the follow-up period. In those individuals with previous falls, there was a significantly increased risk of hospitalization (odds ratio 5.61, 95% CI 1.18-26.7). Furthermore, three factors were significantly associated with the risk of fall, including handgrip strength, malnutrition and Mini-Mental State Examination score. Conclusions The results of the present study showed that hospitalization was a frequent event in residents with dementia living in a long-term care facility. The major predictor for hospital admission was history of a previous fall. Screening those with dementia for history of injurious falls and associated risk factors for falling could help identify those at risk of hospitalization, thus necessitating a comprehensive intervention to reduce hospitalization.

Aim To develop experimental multi-domain interventions for older people with mild-to-moderate dementia, and to evaluate the effect of delaying cognitive and physical decline, and improvement or prevention of geriatric syndromes during 1-year follow up. Methods Participants aged 65 years and older with mild-to-moderate dementia (clinical dementia rating [CDR] 1 or 2) were grouped as intervention in Jia-Li Veterans Home and usual care model in the community (Memory clinic). All residents in Jia-Li Veterans Home received comprehensive intervention, including Multi-disciplinary team consultation and intervention, Multi-component non-pharmacological management, geriatric syndromes survey and intervention by CGA, and a dementia friendly medical Green channel Approach (2MCGA). The decline of cognitive and physical function are determined by the change of Mini-Mental State Examination score, CDR and the sum of CDR box, as well as activities of daily living based on the Barthel Index. We also screened geriatric syndromes at baseline and 1 year later. Results Participants in the intervention group were older and had a lower educational level, lower body mass index, poor baseline activities of daily living function, lower visual impairment, and higher rates of hearing impairment, polypharmacy and risk of malnutrition. The residents receiving 2MCGA had lower baseline Mini-Mental State Examination scores, and higher CDR. For residents in Jia-Li Veterans Home, all cognitive measurements except Mini-Mental State Examination were significantly associated with delaying the decline of cognition after analyzing by multiple linear regression, and multivariate logistic regression also showed that patients living in the community was independently associated with a higher odds ratio for activities of daily living decline (3.180, 95% CI 1.384-7.308, P = 0.006). There are also more improvement in their baseline geriatric syndromes and suffered less from new geriatric syndromes, including falls, urinary incontinence, and risk of malnutrition. Conclusions The 2MCGA intervention shows strong delays in the decline of cognition and physical function for older residents with mild-to-moderate dementia. Furthermore, this strategy can also improve or prevent the onset of new geriatric syndromes, especially fall episodes, urinary incontinence and risk of malnutrition.

Aim To evaluate the impact of living arrangements on mortality and functional decline among older patients with dementia or cognitive impairment after discharge from a geriatric evaluation and management unit (GEMU) in Taiwan. Methods The present retrospective cohort study used data from the Veteran Affairs Comprehensive Geriatric Assessment from January 2015 to May 2016 for analysis. Data of patients aged 65 years and older with dementia or cognitive impairment at admission to the GEMU of Taipei Veterans General Hospital during the study period were retried for study. The Veteran Affairs Comprehensive Geriatric Assessment included demographic characteristics, Clinical Frailty Scale, Braden Scale, St. Thomas's Risk Assessment Tool in Falling Elderly Inpatients Scale, Cumulative Illness Rating Scale for Geriatrics, Barthel Index, Instrumental Activities of Daily Living, Mini-Mental State Examination, Geriatric Depression Scale-5 and Mini-Nutritional Assessment - Short Form, as well as common geriatric syndromes. All patients were categorized into the home care group and institutional care group based on their living arrangement before GEMU admissions. Six-month mortality and decline in Barthel Index were defined as adverse clinical outcomes. Results Overall, data of 395 patients were used for analysis. The baseline comparisons showed that the institutional care group was more likely to be unmarried, have lower education, lower risk of falls and less polypharmacy, but more likely to experience functional decline at follow up than the home care group. Multivariate logistic regression showed that male (OR 3.59, 95% CI 1.04-12.38, P = 0.043) and higher Cumulative Illness Rating Scale for Geriatrics score (OR 4.08, 95% CI 1.49-11.19, P = 0.006) were associated with mortality, whereas the institutional care group (OR 0.30, 95% 0.09-0.99, P = 0.048) and lower Braden Scale (OR 0.80, 95% CI 0.67-0.94, P = 0.008) were protective against mortality. However, the institutional care group was independently associated with functional decline during the follow-up period (OR 2.19, 95% CI 1.12-4.29, P = 0.022). Conclusions Institutional care was associated with lower 6-month mortality risk for patients with dementia or cognitive impairment after discharge from the GEMU, but this group was more likely to experience functional decline. Further prospective study is required to clarify the clinical impact of living arrangements on long-term outcomes when people with dementia or cognitive impairment are admitted to acute hospitals.

Objective: Older patients with diabetes mellitus are at a higher risk of developing diabetic macro- and micro-vascular complications and cardiovascular diseases than younger diabetes mellitus patients. However, older diabetes mellitus patients are very heterogeneous in their clinical characteristics, diabetes mellitus-related complications and age at disease onset. This study aimed to evaluate the all-cause mortality rates and adverse health outcomes among older adults with new-onset diabetes mellitus through a nationwide population-based study. Design: A retrospective cohort study. Setting: 2001-2011 data of the National Health Insurance database. Population: Nationally representative sample of Taiwanese adults aged 65 years and older with propensity score-matched controls. Main outcome measures: All-cause mortality and adverse health outcomes. Results: During the study period, 45.3% of patients in the diabetes mellitus cohort and 38.8% in the non-diabetes mellitus cohort died. The adjusted relative risk for mortality in the diabetes mellitus cohort compared to the non-diabetes mellitus cohort was 1.23 (95% Confidence Interval [CI]=1.16-1.30) for males and 1.27 (95%CI=1.19-1.35) for females. During the follow-up period, 8.9% of the diabetes mellitus cohort and 5.8% of the non-diabetes mellitus cohort developed cardiovascular diseases; the diabetes mellitus cohort had an adjusted relative risk of cardiovascular complications compared to the non-diabetes mellitus cohort of 1.54 (95%CI=1.36-1.75) for men and 1.70 (95%CI=1.43-2.02) for women. The adjusted relative risk of mortality in the patients with hypoglycemia compared to non-hypoglycemia patients in the diabetes mellitus cohort was 2.33 (95%CI=1.81-3.01) for men and 2.73 (95%CI=2.10-3.52) for women after adjustment for age, Charlson comorbidity index, acute coronary syndrome, respiratory disease, cancer, infectious disease and nervous system disease at baseline. Conclusions: New-onset diabetes in older adults is associated with an increased risk of mortality, and hypoglycemia is an important marker of this association. Individualized care plans stratified by age at onset, duration of disease, comorbidity and functional status, as well as hypoglycemia avoidance, would benefit the management of diabetes in older adults.

Aim To evaluate the survival benefits of different models of post-acute care ( PAC) services for older patients with hip fractures in Taiwan Methods This was a prospective cohort study that recruited elderly patients with hip fractures receiving surgical treatment from 2007 to 2009 for study. All patients were provided home-based PAC, institution-based PAC or conventional home care ( CHC) based on their capacity of family care resources. Functional status and survival status was followed for 4 years. Results Overall, 453 hip fracture patients (mean age 81.9 ± 6.8 years, 58.8% men) were recruited for the present study. Among them, 29.4% (133/453) patients received home-based PAC, 25.6% (116/453) patients received institution-based PAC and 45.0% (204/453) received CHC. During follow up, 28.9% (131/453) died within the mean of 940.3 ± 453.40 days. Adjusted for age, sex, living status, visual acuity, mood status, previous fall history, and prefracture activities of daily living ( ADL) and instrumental activities of daily living ( IADL), ADL fully recovered patients were significantly more likely to survive in the 4-year follow up ( HR 2.791, P = 0.01, 95% CI 1.261-6.149). Patients receiving either home- or institution-based PAC had better survival than the CHC group after adjustment for age, sex, living status, visual acuity, mood status, previous fall history, prefracture ADL and IADL ( HR 0.486, P = 0.008, 95% CI 0.284-0.832 for home-based PAC; HR 0.546, P = 0.036, 95% CI 0.311-0.960 for institution-based PAC). Conclusions PAC services were of great survival benefit for elderly hip fracture patients, and the home-based model was more likely to achieve complete functional recovery, which was important for long-term survival.

Objectives: To evaluate the prevalence of malnutrition and its impact on mortality, functional decline and cognitive impairment among elder residents in long-term care settings. Designs: A prospective cohort study. Settings: Two veteran homes in Taiwan. Participants: A total of 1,248 male residents aged equal or more than 65 years. Measurements: Charlson's comorbidity index (CCI), Minimum data set (MDS), resident assessment protocols (RAP), Activity of daily living-Hierarchy scale, Cognitive Performance Scale, MDS Social engagement scale. Results: The mean age of participants is 83.1 ± 5.1 years, and the prevalence of malnutrition was 6.1%. Inadequate dietary content (57.9%) and unintentional weight loss (31.6%) account for the majority of malnutrition identified by MDS tool. Higher 18-month mortality rate (25% vs. 14.2%), higher baseline CCI (median 1 vs. 0), and higher baseline sum of RAP triggers (median 8.5 vs. 5) were noted among residents with malnutrition. Furthermore, malnutrition was shown predictive for functional decline (OR: 3.096, 95% CI: 1.715-5.587) and potential cognitive improvement (OR: 2.469, 95% CI: 1.188-5.128) among survivors after adjustment for age, body mass index and CCI. Conclusion: Malnutrition among elder men residing in veteran homes was associated with multimoridities and higher care complexity, and was predictive for mortality and functional decline.

Abstract: Objectives: The objective of this study was to evaluate the benefits of influenza vaccination against hospitalization and mortality on frail elderly people. Design: The design was a population-based retrospective cohort study. Setting: Taiwan's National Health Insurance claims data. Participants: Participants were 5063 frail seniors, followed up for four years. Measurements: Measurements included age, gender, socioeconomic status, living areas, use of annual health examinations, comorbid conditions, use of influenza vaccine, frailty as defined by the Adjusted Clinical Group, hospitalization, and mortality in the observation period. The efficacy was presented as comparing ever versus never vaccinated people during the entire study period without regard to seasons. Results: Compared with those without influenza vaccination, vaccinated elderly individuals were younger, more likely to be men, have higher socioeconomic status, live in rural areas, have a higher rate of receiving a health examination, and have similar medical conditions. In the Cox proportional hazards analysis, influenza vaccination reduced by 7% the risk of hospitalization (95% confidence interval [CI] 0.86–0.99) and by 44% the risk of mortality (95% CI 0.51–0.62). Conclusion: Influenza vaccination was effective against hospitalization and mortality among the frail elderly. These results uphold the current universal influenza vaccination policy, and encourage policymakers to adopt strategies to improve vaccination use. [Copyright &y& Elsevier]

Aim The clinical effectiveness of non-pharmacological interventions on behavioral and psychological symptoms of dementia ( BPSD) among older Chinese with dementia remains unclear, and the evidence supporting the benefits of a non-pharmacological approach on psychotic symptoms is scarce. Methods A prospective cohort study including 104 older men with dementia living in two veterans homes in Taiwan was carried out in 2011. An organized program of music therapy, orientation training, art-cognitive activities and physical activities was carried out for the intervention group. All participants were evaluated for neuropsychiatric inventory (NPI), defined daily dose of psychotropic drug use, Barthel Index, Instrumental Activities of Daily Living, Mini- Mental State Examination, Geriatric Depression Scale, Tinetti balance score and Tinetti gait score. Results Overall, 104 residents were enrolled and 92 of them completed the study. The intervention group had a more significant reduction than the reference group in the overall NPI score (−2.36, P = 0.046), and in the subcategories of delusion (−0.9, P = 0.018), hallucination (−0.82, P = 0.004) and agitation (−0.91, P = 0.038). Multivariate analysis showed that the non-pharmacological intervention was associated with a favorable outcome in overall NPI score ( OR 4.113, P = 0.013) and in the subcategories of hallucination ( OR 14.309, P = 0.049) and agitation ( OR 6.604, P = 0.037). Meanwhile, a higher baseline NPI score was also associated with a favorable outcome in overall NPI score, and in the subcategories of delusion, hallucination and agitation. Conclusion Non-pharmacological interventions have a positive effect on behavioral and psychological symptoms of dementia, not only in outward symptoms like agitation, but also intrinsic psychotic symptoms like hallucination and delusion, and agitation in older Chinese men with dementia.

Aim Although patients admitted to post-acute care ( PAC) units are usually clinically stable, unexpected medical conditions requiring acute ward readmissions still occur and can jeopardize the clinical effectiveness of PAC services. The main purpose of the present study was to evaluate predictive factors for clinical instability of patients in PAC units to improve the quality of PAC services. Methods This was a nationwide multicenter cohort study that recruited patients from five PAC units in Taiwan between July 2007 and June 2009. All patients received the comprehensive geriatric assessment ( CGA) within 72 h of PAC unit admissions. Conditions requiring acute ward re-admissions from PAC units were defined as clinical instability. Causes of clinical instability for all patients and data of CGA were collected for analysis. Results Of 918 enrolled participants, 119 (12.9%) experienced acute ward readmissions, including 106 (89.1%) admissions related to medical conditions and 13 (10.9%) for surgical causes. Common conditions included diseases of the respiratory system ( n = 32, 26.9%), genitourinary system ( n = 24, 20.2%) and digestive system ( n = 14, 11.8%). Surgical conditions, mainly fractures and dislocation of upper limbs, were significantly more likely to occur later ( P = 0.05) in the PAC unit admissions than medical conditions. Compared with the non-readmission group, the readmission group was leaner (mean body mass index 21.1 ± 2.8 vs 22.0 ± 3.8 kg/m2, P = 0.007), having poorer functional status (mean Barthel Index 41.0 ± 19.4 vs 45.4 ± 20.3, P = 0.02; mean IADL: 1.3 ± 1.6 vs 1.7 ± 1.8, P = 0.016), poorer cognitive function (mean Mini-Mental State Examination: 16.8 ± 6.4 vs 18.3 ± 6.4, P = 0.022), poorer ambulation (mean Timed Up & Go test 32.7 ± 18.7 vs 26.6 ± 11.7 s, P = 0.039) and poorer nutritional status (mean Mini-Nutrition Assessment 13.3 ± 5.7 vs 15.4 ± 5.8, P < 0.001), but similar in depression status (mean Geriatric Depression Score 3.7 ± 3.3 vs 3.4 ± 2.8, P = 0.247). In multivariate logistical regression model, lower Mini-Mental State Examination score was the only independent predictor for clinical instability (odds ratio 3.8, 95% confidence interval 1.348-10.870, P = 0.012). Conclusion Approximately 13% of PAC patients might experience acute ward readmissions, and nearly 90% of them are caused by medical conditions. Poor cognitive function is a significant predictive factor for clinical instability in PAC, which deserves more clinical attention for all PAC patients. Geriatr Gerontol Int 2014; 14: 267-272..

Aim Sarcopenia is a well-recognized geriatric syndrome, which is associated with a variety of adverse outcomes. The present study aimed to evaluate the prevalence of sarcopenia and its associative clinical characteristics in Taiwan. Methods Data of the I- Lan Longitudinal Aging Study ( ILAS) were retrieved for this study. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People criteria, and comparisons of demographic characteristics, physical performance, body composition, cardiometabolic profiles and functionality indicators were carried out. Results Overall, data of 1008 participants (mean age 65.2 ± 9.3 years, male 50.6%) were retrieved for analysis. The cut-off value of relative appendicular skeletal muscle was 7.0 kg/m2 for men and 5.9 kg/m2 for women. Sarcopenia was significantly related to low body mass index, smaller waist circumference, poor nutrition and poor cognition. The mean carotid intima-media thickness and cardiometabolic parameters showed no statistically significant findings. Conclusions The present paper showed the epidemiology of sarcopenia, and the strong connection to functionality indicators. However, sarcopenia was not associated with cardiometabolic risk or carotid intima media thickness in the present study. Geriatr Gerontol Int 2014; 14 (Suppl. 1): 36-45. [ABSTRACT FROM AUTHOR]

Background: Although the clinical effectiveness of community hospital-based postacute care (PAC) services has been shown, little was known regarding the impact of depression on the clinical outcomes of older patients receiving PAC services in Taiwan. Methods: From January 2009 to August 2010, patients aged 65 years and older referred from tertiary medical centers or acute wards of community hospitals to PAC units were invited for study. All patients received the 4-week Comprehensive Geriatric Assessment-based intervention program in the PAC units. The functional assessment was composed of Geriatric Depression Scale–Short Form (GDS), Mini-Mental Status Examination, Barthel Index, Instrumental Activities of Daily Living, and Braden Score. Results: Among the 401 participants (mean age, 82.0 years; 95.5% males), 66 (16.5%) patients were depressed at PAC unit admission. Depressed patients had significantly lower Barthel Index (38.1 ± 2.4 vs. 47.6 ± 1.2, p = 0.002) and Braden Score (17.7 ± 0.3 vs. 18.8 ± 0.2, p = 0.004) than nondepressed patients. Improvement was noted on all measures of functional outcome among patients receiving PAC services. Furthermore, GDS was significantly improved in depressed patients (from 6.4 ± 0.2 to 2.8 ± 0.2 in depressed patients vs. from 1.6 ± 0.1 to 0.9 ± 0.1 in nondepressed patients, p < 0.001). Conclusion: Depression was common when patients were newly admitted to PAC services, which was highly associated with poorer physical function. Improvement in physical function and depressive symptoms among all patients after PAC service was found, and the presence of depressive symptoms at PAC admission did not predict any adverse outcome of PAC services.

Aim Skeletal muscle loss is a common feature of aging, and is associated with unfavorable outcomes. Although several indexes of skeletal muscle mass measurement have been developed, the most optimal index for sarcopenia diagnosis among Asian populations has remained unclear. The present study aimed to evaluate the relationship between skeletal muscle mass and physical performance among community-dwelling people in Taiwan. Methods Data of the I- Lan Longitudinal Aging Study ( ILAS) were retrieved for study. Comparisons between demographic profiles, physical performance and skeletal muscle mass (measured by dual-energy X-ray absorptiometry) were carried out. Skeletal muscle mass expressed by lean body mass divided by squared height ( LBM/ht2), appendicular muscle mass divided by squared height ( ASM/ht2) and percent skeletal muscle index ( SMI%) were compared between measurements of physical performance. Results Overall, the data of 532 participants (mean age 64.6 ± 9.5 years, male 53.0%) were retrieved for analysis. Age was associated with poorer physical performance, and decreased ASM/ht2 and LBM/ht2, but not SMI%. Skeletal muscle mass ( SMI%) was less significantly related to slow walking speed than ASM/ht2 in men. In women, all three muscle indexes showed no significant association between slow walking speed. In contrast, low handgrip strength was strongly associated with decreased skeletal muscle mass (measured by ASM/ht2 and LBM/ht2, but not SMI%) in both men and women. Conclusions Skeletal muscle mass was significantly associated with handgrip strength along with aging, but the association of skeletal muscle mass and walking speed was less significant. In sarcopenia diagnosis among Asian populations, ASM/ht2 should be the most suitable index for skeletal muscle mass measurements, and physical performance should be measured universally beyond measurements of skeletal muscle mass.

Aim Medication-related anticholinergic burden is a quality indicator for geriatric pharmacotherapy; however, little is known regarding the benefits of reducing anticholinergic burden for demented patients Methods Demented residents in a Veteran Home were enrolled for this study and an educational program was held for primary care physicians providing services at the Veterans Home. Residents were assigned to the intervention group if the primary care team could adhere to the research protocol and the remaining residents were assigned to the reference group receiving conventional care. Anticholinergic burden was estimated by Clinician- Rated Anticholinergic Score ( CR-ACHS). Healthcare outcomes; for example, hospitalizations, mortality, cognitive and physical function, were compared between groups. Results Overall, 53 of the 67 demented residents (mean age 83.4 ± 4.4 years) completed this study. Anticholinergic exposure was found in 38 participants (56.7%) at baseline, in which antipsychotics ( n = 29, 76.3%) and antidepressants ( n = 19, 50%) were the most common agents. Compared with participants in the reference group, CR-ACHS was significantly reduced in the intervention group at 12-week follow up (intervention group vs reference group = 0.5 ± 1.1 vs 1.1 ± 1.3, P = 0.021), whereas the mean Mini-Mental State Examination and Barthel Index were similar between groups. In contrast, no clinical complication was observed regarding medication adjustments during the study period. Conclusions Anticholinergic burden can be successfully and safely reduced through an educational program for primary care physicians, but the benefit of reducing anticholinergic burden remained unclear within the first 12 weeks. Further investigation is required to evaluate the long-term benefits of reducing anticholinergic burden for demented older adults. Geriatr Gerontol Int 2013; 13: 694-700. [ABSTRACT FROM AUTHOR]

Background: Although metabolic syndrome (MetS) has been reported to be associated with cognitive decline and dementia, little was known about late-life MetS and cognitive decline among older old population. The main purpose of this study was to evaluate the role of MetS and cognitive decline among men aged 75 and over in Taiwan. Methods: This is a prospective cohort study which recruited men aged 75 years and older with intact cognitive function living in the Banciao Veterans Home, a retirement community for veterans in northern Taiwan. All participants received complete history taking, physical examinations, global cognitive tests and laboratory tests. Cognitive status was re-evaluated one year after enrollment to evaluate the role of MetS to cognitive decline in this study population. Results: Overall, 338 people participated in the study and 62 of them were excluded due to low baseline MMSE score, and the remaining 276 people (mean age: 82.4±4.2 years) were enrolled for study. The prevalence of MetS and annual cognitive decline were 22.5% and 15.6%, respectively. During the follow-up period, 9 (3.3%) participants died, 229(83.0%) complete the study. Subjects with cognitive decline were older and had lower serum levels of serum total cholesterol. Multivariate logistic regression showed that older age (OR:1.13, 95% C.I.: 1.01-1.25, P=0.026) and central obesity (OR: 4.19, 95% CI: 1.26-13.91, P=0.019) were independent risk factors for cognitive decline; and MetS defined by Adult Treatment Panel III was a protective factor (OR: 0.20, 95% CI: 0.04-0.94, P=0.041). The protective effect of MetS remained the same when MetS was defined by the criteria of International Diabetes Federation. Conclusions: Age and central obesity were significant risk factors of cognitive decline, but late-life MetS, however defined, had protective effect on cognitive function. Further investigation is needed to clarify the possible mechanism of MetS and cognitive function in older adults. [ABSTRACT FROM AUTHOR]

Background: Metabolic syndrome (MetS) was common in the elderly, but its prognostic significance in older old population remained unclear. The main purpose of this study was to evaluate the survival impact of MetS among older men aged 75 and over in Taiwan. Methods: From 2008, residents aged 75 years and older of Banciao Veterans Home were invited for study and were followed for 3 years. All participants received history taking, physical examinations, and laboratory tests. Mortality was determined by Veteran Affairs Death Registry, which was linked to the National Death Registry. Results: Overall, 680 men (mean age: 82.5±47 years) were enrolled for study and the prevalence of MetS was 31.6%. During the follow-up period, 140 (20.6%) participants died, and the causes of death included infectious diseases (62, 9.1%), cardiovascular disease (37, 5.4%), cancer (20, 2.9%), and others (21, 3.1%). MetS subjects had a significantly higher prevalence of hypertension, diabetes mellitus, and having higher body mass index, waist circumferences, systolic blood pressure, fasting blood glucose, serum triglyceride and lower HDL-C level than non-MetS subjects. However, MetS subjects were less likely to die during study period (16.3% vs. 22.6%, P=0.059). Multivariate logistic regression showed that older age (OR: 1.04, 95% C.I.: 1.00-1.08, P=0.04), diabetes mellitus (OR: 2.10, 95% CI: 1.34-3.30, P=0.001) were independent risk factors for mortality; and serum total cholesterol and triglyceride were protective factors (OR: 0.99, 95% CI: 0.99-1.00, P=0.037 for cholesterol; OR: 0.99, 95% CI: 0.99-1.00, P=0.013 for triglyceride). Adjusted for age, diabetes mellitus, serum levels of total cholesterol, and triglyceride, MetS played a potential trend of survival benefits among study subjects (HR: 0.71, 95% CI: 045-1.12, P=0.144). Conclusions: The prevalence of MetS among men aged 75 years and over was 31.6%, and the 3-year mortality rate was 20.6%. Older age, diabetes mellitus, lower serum cholesterol and lower serum triglyceride were independent risk factors for mortality. Further investigation is needed to clarify the prognostic impact of MetS in older adults. [ABSTRACT FROM AUTHOR]

Abstract: Background: Although all classes of antihypertensive treatment can successfully reduce morbidity and mortality of cardiac pathology, prevention of target organ damages is of great importance beyond blood pressure lowering. Unlike most dihydropyridines, lercanidipine dilates both afferent and the efferent arterioles of nephrons, so it may provide renoprotective effects, which other CCBs may not have. The main purpose of this study is to compare the renoprotective effect of lercanidipine and amlodipine among hypertensive people aged 55years and older with newly diagnosed hypertension or those who were treatment-naïve for one month. Methods: The study is a prospective, open-labelled, randomized, controlled trial to enrol 232 hypertensive patients aged ≥55 years. Subjects will be randomized into lercanidipine arm (10–20mg/day) and amlodipine arm (5–10mg/day) by 1:1 ratio. The dosage can be up-titrated to 20mg/day (lercanidipine group) and 10mg/day (amlodipine group), respectively, at week 4 or any following visit thereafter. Efficacy and safety data will be collected at week 4, 12 and 24 by evaluating the blood pressure lowering, estimated glomerular filtration rate, creatinine clearance, and urine albumin-creatinine ratio. Conclusions: The reno-protective effects of new generation of CCBs such as lercanidipine administered to patients with hypertension are not investigated well. After all, this study will bring benefit to older patients who need drugs with both excellent anti-hypertensive and reno-protective efficacy. And the results will be provided for future treatment guideline of elder population in Taiwan. [Copyright &y& Elsevier]

Objective: To determine the relationships among diabetes mellitus (DM), glycemic control, and long-term care facility (LTCF)–acquired pneumonia. Design: Prospective cohort study. Setting: Ten private LTCFs in Taiwan. Participants: Participants were 233 LTCF residents. Measurements: Barthel index (BI), Charlson comorbidity index (CCI), hemoglobin A1c, episodes of LTCF-acquired pneumonia. Intervention: None. Results: A total of 233 residents (76.9 ± 10.6 years, 54.9% males, 27.9% diabetic) from 10 private LTCFs participated. There were 173 LTCF-acquired pneumonia episodes. The incidence of LTCF-acquired pneumonia between patients with and without diabetes, or between diabetic subjects with different status of glycemic control was similar. Adjusted for baseline BI, CCI, feeding tube placement, and baseline serum albumin, DM was not a significant risk factor for LTCF-acquired pneumonia. Poorer glycemic control (HbA1c >7%) was not a significant risk factor for LTCF-acquired pneumonia in diabetic subjects. Conclusions: Tighter glycemic control did not protect diabetic LTCF residents from pneumonia. A prospective randomized controlled trial is needed to determine the optimal goal of glycemic control for LTCF residents. [Copyright &y& Elsevier]

Objective: Accurate prediction of life expectancy in long-term care facilities (LTCFs) is important, but previous studies emphasized demographic characteristics, disease diagnosis, or comorbidity. The purpose of this study was to evaluate the roles of geriatric care problems and comorbidity in predicting 12-month mortality in LTCFs. Design: Prospective, observational. Setting: Veterans Care Home. Participants: Residents of Banciao Veterans Care Home. Measurements: A minimum data set (MDS) was implemented, and resident assessment protocol (RAP) triggers were collected as geriatric care problems. Comorbidity of the residents was evaluated using Charlson''s comorbidity index (CCI). Results: A total of 559 residents (mean age = 80.9 ± 5.3 years, all males) were successfully followed, and 50 residents (7.9%) died during the study period. Compared with survivors, deceased subjects had a higher sum of RAP triggers (4.9 ± 2.0 versus 4.1 ± 2.0, P = .004) and CCI (1.2 ± 1.2 versus 0.7 ± 0.9, P = .014), and were more likely to be hospitalized (1.6 ± 1.9 versus 0.4 ± 0.9, P < .001) and visit the emergency department (0.9 ± 1.2 versus 0.5 ± 1.2, P = .012). Moreover, deceased subjects were more prone to have cognitive loss, urinary incontinence, and behavioral symptoms than survivors (P all < .05). A Cox proportional hazards model showed that both CCI (HR = 1.44, 95% CI: 1.13–1.82, P = .003) and the sum of RAP triggers (HR = 2.03, 95% CI: 1.08–3.82, P = .028) were significantly associated with 12-month mortality. Conclusion: Independent of comorbidity, the sum of geriatric care problems is a significant predictor of 12-month mortality in a veterans care home. Further intervention studies are needed to evaluate whether elimination of these care problems can improve survival in the long-term care setting. [Copyright &y& Elsevier]

• The existing body of literature regarding the relationship between subjective aging and biological age is limited and hampered by methodological constraints, including inadequate adjustments for age and variations in the definitions of frailty. • Participants reporting subjective aging were older, more likely to be female, unmarried or not cohabiting, had limited literacy skills, and were more likely to be unemployed compared to those who did not report subjective aging. • Our study findings revealed that there was no significant association between subjective aging and elevated biological age, as measured by the frailty index, across all age groups. However, a noteworthy trend was observed within the younger age group. This study aims to investigate how subjective aging influences the psychological and behavioral responses of older individuals, specifically focusing on the associations between subjective aging and longitudinal changes in biological age. This is a retrospective cohort study retrieving data from the Taiwan Longitudinal Study on Aging (TLSA), over a 4-year follow-up period. Subjective aging is assessed by asking participants if they perceive themselves as old, while frailty is measured using a frailty index comprising 34 deficits from various domains. Participants are categorized into three groups based on their chronological age. The association between subjective aging and transition of biological age (as indicated by an increased frailty index) from 2011 to 2015 is examined using logistic regression models. The study consisted of 2412 participants, who were categorized into middle-age (n = 1,082), young-old (n = 779), and old-old (n = 551) groups. Among them, individuals exhibiting subjective aging at baseline were more likely to be older in chronological age, female, illiterate, and unemployed, compared to those without subjective aging. The adjusted odds ratios (aORs) for the association between subjective aging and an increased biological age were 1.72 [95% CI: 0.88–3.34], 1.61 [0.77–3.37], and 1.08 [0.65–1.80], in the middle-age, young-old, and old-old groups, respectively. No significant associations were found between changes in biological age and subjective aging across various chronological age groups. Notably, within the younger age group, a discernible trend towards an association was observed, indicating the potential age-related nuances in the complex interrelation between subjective age, biological aging, and chronological aging.

Aim Frailty is a highly prevalent geriatric syndrome, characterized by increased vulnerability to subsequent morbidity and mortality. The association between frailty and preclinical atherosclerosis remains uncertain. The aim of the present study was to clarify the relationship between frailty, preclinical atherosclerosis and inflammatory markers in older adults. Methods We enrolled 1798 inhabitants of I-Lan County of Taiwan (855 men, 47.5%; mean age 64 ± 9 years, range 50-92 years). Assessment of frailty was based on the Cardiovascular Health Study criteria. Common carotid artery intima-media thickness (CIMT) was determined using carotid Doppler ultrasonography. Results Overall, 955 participants (53.1%) were non-frail, 724 (40.2%) were pre-frail and 119 (6.7%) were frail. Frail and pre-frail participants had significantly increased CIMT, high-sensitivity C-reactive protein, glycated hemoglobin and urine albumin-to-creatinine ratio, but had lower insulin-like growth factor-1 level and decreased femoral neck bone mineral density (BMD). By multivariate analysis, age (OR 2.53, 95% CI 1.92-3.33), C-reactive protein (OR 1.19, 95% CI 1.00-1.42), CIMT (OR 1.27, 95% CI 1.04-1.55) and femoral neck BMD (OR 0.49, 95% CI 0.38-0.65) were independently associated with frailty. Conclusions The present study showed the epidemiology of frailty, and the strong connection to aging, increased CIMT, enhanced inflammation and decreased femoral neck BMD. These results suggested that preclinical atherosclerosis, inflammation and femoral neck BMD were potentially modifiable risk factors for frailty. Geriatr Gerontol Int 2017; 17: 2449-2454.

Aim There is a complex interrelationship between long sleep duration, frailty, chronic inflammation and mortality among the community-dwelling middle-aged and elderly population, which remains unclear and deserves to be investigated. The current study intended to explore these associations by using a prospective population-based cohort study. Methods A total of 937 community-dwelling middle-aged and elderly people were enrolled. Sleep patterns of the study participants were categorized as short (<6 h), average or long (≥8 h). Sleep disturbance was defined by daytime dysfunction defined by the Pittsburg Sleep Quality Index. Frailty was defined as three or more phenotypes of Fried's Frailty. Results During an average of 4.7 years follow up, 72 (7.7%) study participants died. The adjusted hazard ratio (HR) for death of long sleepers was 2.42 (95% confidence interval [CI] 1.38-4.27), HR of long sleepers plus frailty was 2.37 (95% CI 1.35-4.19) and HR of long sleepers plus log interleukin-6 was 2.11 (95% CI 1.19-3.76). Adjusted HR of daytime dysfunction was 1.79 (95% CI 1.09-2.94). The association between daytime dysfunction and mortality became statistical insignificant after further adjustment for frailty. Conclusions Long sleep duration, independent of frailty and interleukin-6, was associated with 5-year mortality in older adults. The relationship between daytime dysfunction and death diminished after adjusting for frailty. Geriatr Gerontol Int 2017; 17: 1481-1487. [ABSTRACT FROM AUTHOR]

The discussion topics include the J-shaped relationship between BMI, mortality, and functional decline, the Longitudinal Older VEterans (LOVE) Study in Taiwan, and the odds ratio for the underweight, overweight, and obese categories. Other topics include variables such as chronic lung disease, diabetes, mood, and nutrition.

Abstract: Medical utilization by elderly population is influenced by a number of factors, and physical disabilities may play an important role. Despite the fact that extensive studies have been carried evaluating medical utilization by older individuals, little is known regarding the impact of physical disabilities on eye care utilization. Using datasets from the Taiwan National Health Interview Survey and National Health Insurance (NHI) system, a sample of 1726 elderly people was obtained for analysis. Older persons with worse Activity of Daily Living (ADL) disabilities were less likely to have eye care (odds ratio (OR): 0.39, 95% confidence interval (CI): 0.25–0.62), but elderly who had Instrumental Activity of Daily Living (IADL) disabilities alone were not associated with lower odds (OR=0.86, 95% CI=0.61–1.20). In addition to the above, female individuals (OR=1.91, 95% CI=1.44–2.53), those with poorer vision (OR=1.89, 95% CI=1.36–2.62), those having eye discomfort (OR=1.66, 95% CI=1.26–2.18 and OR=2.14, 95% CI=1. 32–3.46 respectively for mild and more than moderate eye discomfort), and those with severe eye disease (OR=1.96, 95% CI=1.23–3.10) were more likely to undergo eye care. In conclusion, physical disability is a strong risk factor for lack of eye care utilization among older Taiwanese. The barriers associated with low eye care utilization among individuals with ADL disabilities should be explored in order to facilitate effective policy implementation among those elderly with disabilities so that they are able to receive appropriate eye care.

Objectives Existing studies have indicated that caring for a person with disabilities in a family could result in strong adverse impacts on the health of his or her spouse. However, little is known about the potential joint burden and interactive patterns in a family when both spouses are in poor health. The objective of this study was to evaluate the impacts of self and spousal health statuses on the physical and mental health outcomes of older people in Taiwan. Design Retrospective observational study. Setting The Social Environment and Biomarkers of Aging Study (SEBAS), Taiwan. Participants Data of 1123 study participants from the SEBAS were retrieved for analysis and all participants were divided into 4 groups based on their self-rated and spousal health status: good self–good spousal health (GG), good self–poor spousal health (GP), poor self–good spousal health (PG), and poor self–poor spousal health (PP). Measurements Multinomial logistic regression models were used to evaluate the associations of the different health statuses of couples to disabilities of physical function, daily activity disabilities (activities of daily living, or ADLs, and instrumental activities of daily living, or IADLs) and depressive symptoms. Subgroup analyses were conducted for middle-aged (aged 53 to 64) and older (aged 65 and older) adults to examine whether the impacts of spousal health statuses on the physical and mental health outcomes increased with age. Results The adjusted multinomial logistic regressions showed that people in the PP group were at the highest risk for difficulties in physical function, daily activities, and depressive symptoms. This association was more significant in the elderly population than the middle-aged group. Elderly PP couples were associated with a 7-fold increase in risk of acquiring a disability of physical function (adjusted odds ratio [aOR] 7.5, 95% confidence interval [CI] 2.4–23.6, P < .01), an 8-fold increase in risk of an IADL disability (aOR 8.5, 95% CI 4.1–17.5, P < .01), a 47-fold increase in risk of an ADL disability (aOR 47.3, 95% CI 5.8–387.7, P < .01), and a 10-fold increase in risk of depressive symptoms (aOR 10.6, 95% CI 4.8–23.4, P < .01), compared with the elderly GG groups. Conclusion This is the first study to demonstrate that when both people in a couple have poor health status, it is a significant risk factor regarding difficulties in physical activities, daily activity disabilities, and depressive symptoms. This effect was particularly stronger in elderly couples compared with middle-aged couples. [ABSTRACT FROM AUTHOR]

This study aimed to use the Social Vulnerability Index (SVI) to encapsulate the complex and multidimensional nature of social determinants and their influence on alcohol intake and mortality in middle-aged and older individuals. Cohort study. Data were obtained from the Taiwan Longitudinal Study on Aging (TLSA), with 3945 study participants aged 50 years and older. The TLSA questionnaire defined SVI (51 items including living conditions, social support, socially oriented activities of daily living, social engagement and leisure, empowerment of life, satisfaction about life, and socioeconomic status) and alcohol intake (behavior as well as type and frequency of alcohol intake). Multivariate Cox proportional hazard models were used to estimate the association between alcohol intake and mortality, stratified by sex and SVI groups. Men with high social vulnerability and high alcohol intake exhibit an elevated mortality risk [adjusted hazard ratio (aHR), 1.51; 95% CI, 1.01–2.24], whereas notably, women in similar social circumstances but with moderate alcohol intake face a quintupled mortality risk (>35 g/wk; aHR, 5.67; 95% CI, 2.37–13.61). The impact of alcohol and social vulnerability on mortality was more pronounced in men younger than 65. Among them, those with high social vulnerability and moderate (35–140 g/wk; aHR, 2.83; 95% CI, 1.50–5.36) to high (>140 g/wk; aHR, 2.24; 95% CI, 1.15–4.35) alcohol intake was associated with an increased risk of mortality. Various factors throughout the life course of both men and women significantly impact the risk of all-cause mortality due to alcohol intake, underscoring the importance of social vulnerability as a determinant of both alcohol intake behavior and mortality risk.

• The incidence of dementia increased slightly but the number of cases increased sharply. • A higher likelihood of multimorbidity after being diagnosed with dementia than before. • Dementia cases had increased healthcare usage 1 year before diagnosis, which peaked 1 year afterward. • Usage of psychotropic agents increased over 3 years before diagnosis of dementia. • The cumulative 5-year mortality was nearly 50 % among all identified dementia cases. This study aims to ascertain dementia incidence from 2004 to 2017 in Taiwan, and to examine the disease course in comorbidity, treatments, healthcare usage, and mortality among older people with incident dementia preceding the diagnosis of dementia and afterwards. Taiwan National Health Insurance data on people aged ≥ 65 years with incident dementia from January 2004 to December 2017 were excerpted to estimate annual incidence rates and annualized percentage changes(APCs). For people diagnosed before 2013, annual mortality rates and causes of death during 5-years' follow-up were determined. Changes in 22 diseases/conditions, hospital visits and admissions, and psychotropic medication prescriptions commonly associated with dementia, were examined from 3 years preceding the index diagnosis until 5 years afterwards. From 2004 to 2017, the annual incidence of dementia in Taiwan increased from 30,606 to 50,651, and by > 90 % in women; age-standardized annual incidence increased significantly, with an APC of 0.4 %(p = 0.02). For 372,203 incident cases from 2004 to 2013, annual mortality was∼12 % during 5-years' follow-up. The prevalence of most comorbidities increased by 65–150 % after being diagnosed with dementia. People with incident dementia had increased healthcare usage 1 year before diagnosis, which peaked 1 year afterwards. Psychotropic medication prescriptions increased gradually over 3 years before diagnosis, peaked 3 months afterwards, gradually declined during the next 2 years, then remained stable. The incidence of dementia in Taiwan has increased gradually over time, with an annual mortality risk of∼12 %. Older people with dementia had more healthcare needs and comorbid conditions after dementia diagnosis, highlighting the exigency of person-centered dementia care. [ABSTRACT FROM AUTHOR]

• Both intrinsic capacity (IC) and multimorbidity independently predict incident disability. • Low IC predicts disability greater in older adults, men, and less educated. • Middle-aged adults and women face disability risk from multimorbidity. • Both baseline IC and changes in IC attenuate the risk of incident disability. This longitudinal cohort study aimed to examine the effect of intrinsic capacity (IC) and multimorbidity on the development of new disabilities. The study utilized data from 1,009 participants without disabilities from the I-Lan Longitudinal Aging Study. Multivariable logistic regressions were employed to assess the predictive capability of IC (ranging from 0 to 100) and multimorbidity for incident disability over a 7-year follow-up period. Both low IC (OR 4.9, 95 % CI 2.1–11.1, p < 0.001) and multimorbidity (OR 4.5, 95 % CI 2.2–9.2, p < 0.001) significantly predicted incident disability over the 7-year period. A one-point increase in IC reduced the risk of incident disability by 10 % (OR 0.9, 95 % CI 0.8–0.9, p < 0.001). Among IC subdomains, both better locomotion (OR 0.96, 95 % CI 0.94–0.99, p = 0.014) and psychology (OR 0.97, 95 %CI 0.94–1.00, p = 0.049) significantly reduced the risk of incident disability. Rapid declines in IC significantly predicted incident disability (OR 4.1, 95 % CI 1.8–9.3, p = 0.001), whereas the onset of new multimorbidity or changes in the number of chronic conditions did not demonstrate a significant association with incident disability. The interaction terms between IC and multimorbidity, both categorically (low IC * multimorbidity, p = 0.959) and numerically (IC (per point) * multimorbidity, p = 0.660) were all statistically insignificant. IC exhibited better predictive capacity for 7-year incident disability compared to multimorbidity, so health care services targeting older adults should adopt an integrated care approach that combines both function- and disease-centric strategies.

• Hospitalized older adults with increasing PIMs associated with functional decline. • Increasing PIMs in hospitalized older adults linked to prolonged LOS and mortality. • 65% older adults experienced an increase in PIMs during hospitalization. • An increase of ≥3 PIMs resulted in worse adverse outcomes during hospitalization. • Intervention programs needed to reduce PIMs and improve adverse outcomes. To evaluate the association between the change in the number of PIMs in older adults during hospitalization and adverse outcomes. This retrospective cohort study was conducted in the internal medicine wards of a tertiary teaching hospital between May and December 2017. 3,460 patients (77.5±8.4 years, 60.4% male) were enrolled, and 206 patients died during hospitalization. PIMs were defined using the Beers Criteria as suggested by the American Geriatrics Society. Adverse outcomes studied were functional decline (a loss in 1 or more activities of daily living from admission to discharge), prolonged length of stay (LOS) (≥14 days), and mortality. 2258 patients (65.3%) had increasing PIMs during hospitalization. They tended to be younger (77.0±8.3 versus 78.5±8.5 years, p <0.001) and had lower numbers of PIMs at admission (0.4±0.8 versus 0.8±1.1, p <0.001). Increasing PIM use was strongly associated with greater functional decline (aOR 1.36, 95%CI 1.01–1.67, p =0.005), prolonged LOS (aOR 3.47, 95%CI 2.71–4.44, p <0.001) and higher mortality rate (aOR 2.68, 95%CI 1.75–4.12, p <0.001), even after adjusting for all covariates. We observed a strong association between adverse outcomes and increasing PIMs in older adults during hospitalization (p for trend <0.001). Older adults with increasing PIMs during hospitalization were at greater risk for functional decline, prolonged LOS, and mortality, especially in those with three or more PIMs. Further studies are needed to better understand the complex interactions and to evaluate the effectiveness of intervention programs to lower PIM number and improve discharge outcomes for patients who had increasing PIM use during hospitalization.

• This study provides vital evidence regarding time-varying benefits of PAC services to HRQoL of stroke patients. • Multiple predictors of HRQoL among stroke patients receiving PAC services were identified in this study. • The benefits of the PAC program to health state utilities were significantly greater in men, in those without the prior history of stroke admissions, in those with hemorrhagic strokes, and in those reporting extreme problems in any dimensions of EQ-5D questionnaire. This study aims to evaluate health-related quality of life (HRQoL) of middle-aged and older stroke patients receiving the stroke post care (PAC) program and to identify possible predictors. This is a retrospective cohort study. Demographic characteristics and functional outcomes (modified Rankin Scale, Barthel Index, Mini-Mental State Examination, and the Concise Chinese Aphasia Test) were collected at enrollment. EQ-5D HRQoL questionnaires were administered at the beginning and the end of PAC, and health state utilities were compared. The EQ-5D utilities of stroke patients aged 75–84 years and 85 years or above were estimated to be 0.091 and 0.159 lower than those aged less than 50 years. A decrease of the utility by 0.075 was observed among patients with the prior history of stroke. The EQ-5D utilities of patients having Barthel Index of 21–40, 41–60, and 61–100 were 0.1432, 0.1568, and 0.1387 higher than those having Barthel Index of 0–20, respectively. For patients reporting extreme problems in self-care or any dimension of EQ-5D questionnaires prior to PAC, increases in utilities by 0.0733 and 0.2875 were noted. The EQ-5D utility of PAC service duration rose by 0.0733 per one incremental day. This study provides vital evidence regarding time-varying benefits of PAC services to HRQoL of stroke patients and to identify multiple predictors of HRQoL among stroke patients receiving PAC services. This study thus could serve as good reference to enhance quality of PAC services among stroke patients. [ABSTRACT FROM AUTHOR]

The definition of cognitive frailty and its prediction for adverse outcome of community-living older adults remains controversial. This study aims to evaluate the association between cognitive frailty and all-cause mortality among community-living older adults. Data of the I-Lan Longitudinal Aging Study (ILAS) were retrieved for study. Frailty was defined by Fried's criteria, and a series of neuropsychological assessments, including the Mini-Mental State Examination, Center for Epidemiology Studies-Depression, the delayed free recall in the Chinese Version Verbal Learning Test, the Boston Naming Test, the category (animal) Verbal Fluency Test, the Taylor Complex Figure Test, the digital backward, and the Clock Drawing Test were performed. All participants received blood sampling after 10-hour overnight fast for various biochemical markers. Cognitive frailty was defined as the concomitant presence of dynapenia and cognitive declines in any domains. Overall, data of 678 participants aged 65 years and older (mean age: 73.3 ± 5.3 years) were obtained for the study. The prevalence of cognitive frailty in this study was 13.3%. People with cognitive frailty were significantly older, having higher multimorbidity burden, more likely to be women, and had less skeletal muscle mass. Adjusted for age and gender, both dynapenia without cognitive impairment (hazard ratio [HR]: 5.402; 95% confidence interval [CI]: 1.463-19.954; p = 0.011) and cognitive frailty (HR: 6.682; 95% CI: 1.803-26.116; p = 0.005) were significantly associated with all-cause mortality. The prevalence of cognitive frailty was 13.3% in Taiwan and was predictive for all-cause mortality. Further study is needed to explore the pathophysiology and reversibility of cognitive frailty.

Introduction Sarcopenia is an aging-related health problem in the geriatric population. Sarcopenia reduces muscle mass, muscle strength, and physical performance. Although physical activity is protective against sarcopenia for older adults, there are limited studies in this area. The purpose of this study was to integrate and analyze research on physical activity and sarcopenia in the geriatric population. Methods Studies that assess sarcopenia were searched across electronic databases that included Medline, PubMed, CINAHL, and Cochrane Database of Systematic Reviews. Studies that implemented physical activity-related intervention or research were included. A critical appraisal skills program was used for quality assessment of the selected articles. Study selection and data extraction were counted by 2 independent reviewers. Results Of the 149 references identified through the database search, 10 studies were included in this systematic review. Seven studies were randomized controlled trials, and 3 were cross-sectional or longitudinal. The results of 8 studies indicated significant improvement in muscle mass, muscle strength, and physical performance through exercise intervention, as determined by long-term observation. Conclusions Physical activity is an effective protective strategy for sarcopenia. Most studies of older adults exercise intervention indicated that the participants achieved positive results, but maintenance of muscle strength appeared to depend on continuous implementation of certain types of physical activities. A limitation of these 10 reviewed studies was that there was no consistency in the measurement of sarcopenia. Therefore, sarcopenia measurement needs further investigation. [ABSTRACT FROM AUTHOR]

• Reducing preventable adverse outcomes of HNHC patients has become the priority for health care service delivery. • The risk of potentially preventable adverse outcomes related to HNHC patients suggests potential current gaps in the optimal care quality of health care systems. • The call to develop necessary actions to reduce the impact of multimorbidity, polypharmacy and their combined effects among HNHC patients deserves more attention. The success of modern health care increases life expectancy and prolongs the days of having multimorbidity and functional limitations; the so-defined "high need, high cost (HNHC)" state represents the extreme scenarios of care burden and complexity. This study aims to explore health care utilization and the risk of preventable adverse outcomes stratified by age and HNHC state. We conducted a retrospective cohort study using the National Health Insurance (NHI) database. People aged ≥40 years were included and further stratified by age (middle-aged: 40–64 and older adults: 65) and HNHC state (top 10% of spending). Health care utilization and drug consumption across different groups were obtained. The multimorbidity frailty index (mFI) was developed for further analysis. Cox regression models were used to examine the associations between HNHC and adverse clinical outcomes (preventable hospitalizations, preventable emergency department visits, and mortality). HNHC participants were older, had a higher mFI and drug consumption, and had higher health care utilization. Compared with non-HNHC participants, HNHC participants exhibited a 4.4-fold and 2.4-fold higher risk of preventable hospitalizations in middle-aged (HR=4.41; 95% CI, 4.17–4.65, p <0.01) and older adults (HR=2.44; 95% CI, 2.34–2.55, p <0.01). Similar risks were observed for preventable emergency department visits and mortality (all p <0.01). The HNHC state substantially increased health care utilization, polypharmacy, and potentially preventable adverse outcomes after adjustment for frailty. Intervention studies developing integrated care models using the life-course approach are needed to improve the quality of health care systems in super-aged societies. [ABSTRACT FROM AUTHOR]

• Sex-specific associations between social isolation, loneliness, depression, cognitive function and the relationships with biomarkers remain unclear. • Social isolation was not associated with the development of loneliness in men but was associated with a 2-fold higher risk of loneliness in women. • Other demographics, including being married, self-reported health status, and high education levels, on subsequent loneliness, depression, and cognitive function were also sex-different. To investigate sex-specific associations between social isolation and psychological outcomes and biomarkers among community-dwelling middle-aged and older adults using a nationally representative population-based cohort study. Data from 757 participants from the Social Environment and Biomarkers of Aging Study (SEBAS) were retrieved for analysis, and all participants were stratified by sex. The associations between social isolation and psychological outcomes (loneliness, depressive symptoms, and cognitive impairment) at the 4-year follow-up were examined by multivariate logistic regression models, and associations between social isolation and biomarkers at the 4-year follow-up were examined by multivariate generalized linear models (GLMs). For men, social isolation was not associated with the development of loneliness. However, being married (adjusted odds ratio (aOR) 0.32 [95% confidence interval (CI) 0.13-0.74], p<0.001) was associated with a lower risk of loneliness, indicating potential protective effects of marriage for men. On the other hand, social isolation was associated with a 2-fold higher risk of loneliness in women (aOR 2.26 [1.01-5.09], p<0.001). Social isolation was not associated with depressive symptoms after adjusting for other demographics. For men, being married (aOR 0.51 [0.26-0.99], p<0.05) or having good self-reported health (aOR 0.44 [0.21-0.92], p<0.05) was protective against depressive symptoms. For women, only good self-reported health (aOR 0.30 [0.13-0.70], p<0.01) provided protective effects against depressive symptoms. Similarly, other demographic factors (being married and having a higher educational level) but not social isolation were associated with lower risks of cognitive impairment. No significant associations were noted between social isolation and selected biomarkers. Sex-different associations between social isolation and loneliness were noted; the effects of demographic factors, such as being married, self-reported health status, and high education levels, on subsequent loneliness, depression, and cognitive function were also sex-different. Further intervention studies are needed to explore sex-specific approaches to deal with the interplay of social isolation, loneliness, psychological outcomes and other demographic factors.

To explore the associations of (1) the frailty phenotype or frailty index transition with cause-specific mortality, and (2) different combinations of transition in frailty phenotype and frailty index with all-cause mortality. Retrospective cohort study. Data from 3529 respondents aged >50 years who completed the 1999 and 2003 surveys of the Taiwan Longitudinal Study on Aging were analyzed. Cox regression and subdistribution hazard models were constructed to investigate frailty phenotype or frailty index transitions (by categories of frailty phenotype, absolute and percentage changes in frailty index, and combined categories of the 2 measurements) and subsequent 4-year all-cause and cause-specific mortality, respectively. Among the frailty phenotype transition groups, the improved frailty group had overall mortality risk comparable to that of the maintained robustness/prefrailty group [hazard ratio (HR): 0.9; 95% CI: 0.7–1.2] and lower risk of mortality due to organ failure (HR: 0.4; 95% CI: 0.2–0.8; P =.015), whereas the worsened frailty group had the highest risk of all-cause mortality and death from infection, malignancy, cardiometabolic/cerebrovascular diseases, and other causes (HR: 1.8–3.7; all P <.03). The rapidly increased frailty index group had significantly higher all-cause and every cause-specific mortality than the decreased frailty index group (HR: 1.8–7.7; all P <.05). When frailty phenotype and frailty index transition groups were combined, participants with worsened frailty/rapidly increased frailty index had increased risk under the same frailty index/frailty phenotype transition condition, particularly for large changes in each factor (HR: 1.5–2.2; P <.01 for worsened frailty; 1.7–4.5, P <.03 for rapidly increased frailty index). We found that considering both frailty phenotype and frailty index provided best mortality prediction. These associations were independent of baseline frailty status and comorbidities. Nevertheless, even capturing transitions in frailty phenotype or frailty index only can provide good mortality prediction, which supported adopting these approaches in different clinical settings.

The aim of this study was to evaluate the association of cardiometabolic risk and frailty through a community-based aging cohort in Taiwan In total, 1839 participants (men, 47.5%; mean age 63.9 ± 9.3 years) from the first wave of the I-Lan longitudinal cohort study, recruited between August of 2011 and August of 2013, were retrieved for the analysis of this cross-sectional study. Frailty was defined by Cardiovascular Health Study (CHS) criteria, encompassing un-intentional weight loss, slow walk speed, poor grip strength, exhaustion, and low activity. Comparisons between cardiometabolic risk and frailty status were performed after adjustment for age, hormone parameters, functional measurements, and skeletal muscle mass. Independent association of cardiometabolic risk and frailty status was identified through the multivariate logistic regression model. We found that the prevalence of frailty and pre-frial were 6.8% and 40.5%, respectively. Adjustments for age, blood pressure, low-density lipoprotein cholesterol (LDL-C), uric acid, creatinine, and carotid intima media thickness were not significantly associated with frailty. However, lower total cholesterol and high-density lipoprotein cholesterol (HDL-C), higher high-sensitivity C-reactive protein (hsCRP) and glycemia profiles were significantly associated with frailty. For hormone parameters, dehydroepiandrosterone sulfate (DHEA-S), insulin-like growth factor-1 (IGF-1), and free androgen index were not significantly associated with frailty after age adjustment. In a multivariate logistic regression model, abdominal obesity, homeostasis model assessment of insulin resistance (HOMA-IR), and hsCRP were significantly associated with frailty. The odds ratio (OR) for frailty was 3.57 (95% confidence interval [CI] 1.88-6.78, p < 0.001), 1.30 (95% CI 1.02-1.66, p = 0.032), and 1.66 (95% CI 1.10-2.49, p = 0.016), respectively, in a fully adjusted model. Conversely, higher total cholesterol was associated with a lower prevalence of frailty (OR = 0.44, 95% CI 0.22-0.89, p = 0.023) in the final model. In this study, abdominal obesity, insulin resistance, and inflammation were significantly associated with frailty, and the effect was independent of functional measurement and decline of skeletal muscle mass. An integrated approach targeted at cardiometabolic aging and frailty is needed in clinical practice. [ABSTRACT FROM AUTHOR]

• A potential predictor of dementia conversion in cerebral small vessel disease (CSVD). • CSVD people with mobility frailty had higher risk of dementia at 5.7 years. • Mobility frailty may serve as one clinical marker for adverse outcomes of CSVD. • Mobility frailty might be involved in the mechanism of cognitive declines in CSVD Frailty has been shown to predict adverse outcomes in several diseases. We aimed to evaluate the associations between frailty profiles, both severity and subtype, and dementia risk in a community-based population with asymptomatic (without stroke and dementia) cerebral small vessel disease (CSVD). Individuals with asymptomatic CSVD were recruited from the community-based I-Lan Longitudinal Aging Study between 2011 and 2014 (baseline) and were followed up between 2018 and 2019. All participants underwent CSVD assessment by 3T brain MRI, as well as physical and cognitive assessments at baseline. Univariate and multivariate logistic regression analyses were performed to evaluate the associations between each factor and dementia conversion at follow-up. Among 261 participants with asymptomatic CSVD (64.8 [50.0-89.1, 8.4] years; 136 [52.1%] men), 13 (5.0%) developed dementia during a mean follow-up of 5.7 (0.7) years. Dementia converters were less likely to be robust (30.8% vs. 61.5%) and more likely to be pre-frail/frail (69.2% vs. 38.5%) than non-converters (p = 0.040). Meanwhile, there was significantly more frequent mobility frailty (53.8% vs. 19.8%, p = 0.009), but a similar prevalence of non-mobility frailty in dementia converters compared with non-converters. Univariate analyses showed that neither frailty severity nor CSVD burden was associated with a higher risk of dementia; it was the frailty subtype, the mobility frailty, which was significantly associated with dementia conversion in participants with asymptomatic CSVD, with an odds-ratio of 4.8 (95% CI = 1.5–14.8, p = 0.007). The significance remained after adjusting for age, sex, education and baseline cognitive function, respectively. Mobility frailty was associated with a higher risk of incident dementia in individuals with subclinical CSVD. Mobility frailty might be involved in the pathology of cognitive decline in CSVD and potentially serve as a marker to identify people at risk of cognitive impairment at an early stage of CSVD.

Abstract: Objective: To evaluate the role of allostatic load (AL), either static or dynamic measurements, in predicting all-cause and cause-specific mortality of older people in Taiwan. Design: A prospective cohort study. Setting: Population-based community study. Participants: One thousand twenty-three community-dwelling older people. Measurements: Allostatic load (calculated by systolic blood pressure, diastolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, triglyceride, glycosylated hemoglobin, fasting glucose, waist-to-hip ratio, body mass index, dehydroepiandrosterone sulfate, insulin-like growth factor-1, 12-hour urine cortisol, 12-hour urine epinephrine, 12-hour urine norepinephrine, 12-hour urine dopamine, white blood cell count, neutrophils, interleukin-6, albumin, creatinine) and all-cause and cause-specific mortality from national death registry. Intervention: None. Results: Adjusted for age and sex, each 1-point increase in AL score was associated with 20% incremental risk of mortality [hazard ratio 1.20, 95% confidence interval (CI) 1.09–1.31]. This association can be extended to cause-specific mortality in both sexes in general. In addition, the higher AL score quintile was significantly associated with higher risk of 10-year all-cause mortality (P < .0001). This association was consistent across different cause-specific mortality (ie, malignant neoplasm (P = .008), cardiometabolic diseases (P < .0001), infectious diseases (P < .0001), respiratory diseases (P < .0001), and others (P = .0002), respectively. Compared with AL score decliners, adjusted for age, sex, and baseline AL score in 2000, participants with fast increase had significantly higher mortality (HR 2.68, 95% CI 1.23–5.84, P = .01). The effect was stronger in men (HR 2.83, 95% CI 1.1–7.29, P = .03 in slow increase; HR 4.06, 95% CI 1.56–10.6, P = .001 in fast increase group), but it was insignificant in female participants. Conclusions: Higher AL score or rapid increase of AL score significantly increased subsequent mortality risk in older adults, either measured statically or dynamically. AL is predictive of 10-year mortality regardless of cause of death, and rapid increase in AL score is associated with higher subsequent mortality. [Copyright &y& Elsevier]
