Background: In the past decades knowledge on adequate treatment of affective disorders and awareness of the negative consequences of long-term benzodiazepine use increased. Therefore, a decrease in benzodiazepine use is expected, particularly in prolonged use. The aim of this study was to assess time trends in benzodiazepine use.Methods and Material: Data from the Longitudinal Aging Study Amsterdam (LASA) were used to investigate trends in benzodiazepine use between 1992 and 2002 in two population-based samples aged 55-64 years. Differences between the two samples with respect to benzodiazepine use and to sociodemographic, physical health and mental health characteristics were described and tested with chi-square tests and logistic regression analyses.Results: Benzodiazepine use remained stable over 10 years, with 7.8% in LASA-1 (n = 874) and 7.9% in LASA-2 (n = 919) (p = 0.90) with a persisting preponderance in women and in people with low education, low income, chronic physical diseases, functional limitations, cognitive impairment, depression, anxiety complaints, sleep problems and when using antidepressants. Long-term use remained high with 70% in 1992 and 80% in 2002 of total benzodiazepine use.Conclusion: In the Dutch population aged 55-64, overall benzodiazepine use remained stable from 1992 to 2002, with a high proportion of long-term users, despite the effort to reduce benzodiazepine use and the renewal of the guidelines. More effort should be made to decrease prolonged benzodiazepine use in this middle-aged group, because of the increasing risks with ageing. [ABSTRACT FROM AUTHOR]

BACKGROUND: : Electroconvulsive therapy (ECT) is the most efficacious treatment in severely depressed elderly patients. Relapse and recurrence of geriatric depression after recovery is an important clinical issue, which requires vigorous and safe treatment in the long term. Continuation or maintenance ECT (M-ECT) may play an important role in this respect. METHODS: : In this systematic search, we evaluate the efficacy and safety of M-ECT in preventing depressive relapse in patients age 55 or older. Computer databases were searched for relevant literature published from 1966 until August 2010 with additional references. RESULTS: : Twenty-two studies met the search criteria including three randomized clinical trials. M-ECT was studied in nine studies exclusively in the elderly patients. CONCLUSIONS: : Research on this clinically important topic is sparse. On the basis of available literature, M-ECT is probably as effective as continuation medication in severely depressed elderly patients after a successful course of ECT and is generally well tolerated. To date, methodologically sound studies, which take into account important issues in geriatric depression like cognition, comorbidity, and clinical parameters, are lacking. [ABSTRACT FROM AUTHOR]

Objectives: To study the onset and compare risk factors for pure depression (DEP), pure anxiety (ANX), and comorbid anxiety-depression (ANXDEP) in the aging population.Design: Prospective study with 3-year intervals over a 9-year period.Setting: Data of the Longitudinal Aging Study Amsterdam were used, which is a population-based study among older adults (55-85 years at baseline).Participants: Older adults free of depression and anxiety at baseline (N = 1,712).Measurements: Clinically relevant levels of depression and anxiety were measured with the Center for Epidemiologic Studies Depression scale> or =16 and Hospital Anxiety and Depression Scale > or =7, respectively. A broad range of potential sociodemographic, health, and psychosocial risk factors for anxiety and/or depression were examined by using polytomous logistic regression analyses.Results: Within 9 years, 184 subjects (10.8%) developed DEP, 93 (5.4%) ANX, and 103 (6.0%) ANXDEP. Concerning sociodemographics, higher age and lower educational level were predictors for DEP. Health indicators were predictive for DEP and ANXDEP but not for ANX. Depressive symptoms at baseline were predictive for DEP, whereas initial anxiety symptoms were predictive for ANX and ANXDEP. Neuroticism increased the risk of DEP and ANXDEP. Mixed effects of psychosocial variables were found: DEP was associated with recent widowhood, whereas ANX and ANXDEP were associated with other life events such as having an ill partner.Conclusion: Although onset of ANXDEP demonstrated communality in risk factors, comparing risk factors associated with DEP and ANX revealed more differences than similarities. This underlines the need to distinguish anxiety from depression in preventive strategies. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIMS: It is often assumed that aging is accompanied by diverse and constant functional and cognitive decline, and it is therefore surprising that the well-being of older persons does not appear to decline in the same way. This study investigates longitudinally whether well-being in older persons changes due to Persistent Deterioration of Functioning (PDF). METHODS: Data were collected in the context of the Longitudinal Aging Study Amsterdam (LASA). Conditions of PDF are persistent decline in cognitive functioning, physical functioning and increase in chronic diseases. Measurements of well-being included life satisfaction, positive affect, and valuation of life. T-tests were used to analyse mean difference scores for well-being, and univariate and multivariate regression analyses were performed to examine changes in three well-being outcomes in relation to PDF. RESULTS: Crosssectional analyses showed significant differences and associations between the two PDF subgroups and non- PDF for well-being at T3. In longitudinal analyses, we found significant decreases in and associations with wellbeing over time in respondents fulfilling one PDF condition (mild PDF). For respondents fulfilling two or more PDF conditions (severe PDF), longitudinally no significant associations were found. CONCLUSIONS: Cognitive aspects of well-being (life satisfaction and valuation of life) and the affective element (positive affect) of well-being appear to be influenced negatively by mild PDF, whereas well-being does not seem to be diminished in persons with more severe PDF. This may be due to the ability to accept finally the inevitable situation of severe PDF. [ABSTRACT FROM AUTHOR]

Objective: Insight into the individual care needs of the growing number of people with dementia is necessary to deliver more customized care. Our study aims to provide an overview of the literature on the subjective needs of people with dementia.Method: Electronic databases were searched for publications on subjective needs between January 1985 and July 2005, and reference lists were cross-referenced. Extracts of needs were classified within problem areas of the (Dutch) National Dementia Program and quality of life domains, and the extracts were classified as a "need" (an implicitly communicated felt state of deprivation), "want" (expression of a need) or "demand" (suitable solution to fulfill a need).Results: Subjective needs were found in 34 studies with various research aims, such as awareness and coping. Few studies aimed to measure needs of people with dementia. The most frequently reported needs of people with dementia were the need to be accepted and respected as they are, the need to find adequate strategies to cope with disabilities, and the need to come to terms with their situation. Explicit wants or demands were reported less frequently than needs.Conclusion: The high number of reported needs and the limited number of wants and demands show that people with dementia do not frequently mention how they want their needs to be met. Most reported needs are not instrumental, but are related to well-being and coping. Further research to inventory these needs could help achieve more demand-directed and better attuned care in the future. [ABSTRACT FROM AUTHOR]

The study investigated the impact of change in cognitive functioning and cognitive decline on disability, well-being, and the use of healthcare services among older persons in the Longitudinal Aging Study Amsterdam (LASA). Data were collected from 1,349 subjects, aged 65-85 years, who had scores of 24 and higher on the Mini-Mental State Examination (MMSE) at baseline, over a period of 6 years in three waves. The results indicate that cognitive decline and changes in cognitive functioning in older persons who were either not impaired or only mildly cognitively impaired at baseline have an impact on disability, well-being, and the use of healthcare services. With the aging of the population, the number of persons with cognitive impairment is likely to increase, and appropriate services should be available to them. [ABSTRACT FROM AUTHOR]

Background. The loss of a spouse has been found to have a negative effect on physical and mental health and leads to increased mortality. Whether conjugal bereavement also affects memory functioning has largely been unexamined. The present study investigates the effect of widowhood on memory functioning in older persons.Method. The sample consisted of 474 married women and 690 married men aged 60-85 years in 1992, followed up in 1995 and 1998. During the study 135 (28%) of the women and 69 (10%) of the men lost their spouse. Linear regression analysis was used to examine whether widowed men and women differed from those who had not been widowed in rate of memory change over 6 years. Cross-domain latent-change models were subsequently used to evaluate the extent to which changes in memory are related to changes in other domains of functioning that may be affected by widowhood.Results. Older adults who lost a spouse during follow-up showed a greater decline in memory over 6 years than those who remained married. A higher level of depressive symptoms at baseline was related to lower levels of memory functioning and a greater decline. Memory decline was unrelated to changes in depressive symptoms and physical health.Conclusions. Loss of the spouse is related to a greater decline in memory in older adults. The absence of an association with physical functioning and the weak association with mental functioning suggest that losing a spouse has an independent effect on memory functioning.

The objective of the study was to examine psychological distress in victims of elder mistreatment and to determine whether social support, coping style, mastery, and perceived self-efficacy favorably influence the psychological health of these victims. The study sample consisted of 77 subjects who reported recent chronic verbal aggression, physical aggression, or financial mistreatment, and a control group of 147 subjects who had not been mistreated. All participants were elderly persons who were over 65 years of age and living independently in the community. Social support coping style, mastery, and perceived self-efficacy were measured by means of a standardized home interview. Psychological distress was measured by means of the General Health Questionnaire (GHQ-12). Victims of elder mistreatment had significantly higher levels of psychological distress than nonvictims. Social support showed a favorable effect on the level of psychological distress in victims but not in nonvictims; victim who received more social support showed less psychological distress. A lower sense of mastery, a negative perception of self-efficacy, and a passive reaction pattern were associated with higher levels of psychological distress in victims as well as in nonvictims. The beneficial role of social support, locus of control, and perceived self-efficacy on the level of psychological distress could be of importance in the development of future intervention programs.

Loneliness and social network size have been found to be predictors of mortality in older adults. The objective of this study was to investigate whether loneliness and small social network size are associated with an increased mortality risk and to review the evidence for either network size, or loneliness that constitutes the higher mortality risk. A systematic literature search was performed in PubMed, EMBASE and PsychInfo in January/February 2018 and March/April 2021. Studies that mentioned outcome data were included in the meta-analysis and coded using the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies. The meta-analysis showed that both loneliness and small social network size are associated with mortality risk in older adults (Hazard Ratio 1.10 (95% Confidence Interval 1.06-1.14) for loneliness and 0.96 (95% Confidence Interval 0.93-0.99) for larger network size). Sensitivity analyses according to the Newcastle-Ottawa Quality Assessment Scale yielded varying results. Heterogeneity was large. In conclusion, both loneliness and small social network size in older adults are associated with increased mortality, although the effect size is small. Targeting subjective and objective aspects of older adults' social contacts should be on the agenda of preventive as well as personalized medicine. In order to be able to compare the association between loneliness and network size and mortality, more studies are needed that include both these risk factors., Supplementary Information: The online version contains supplementary material available at 10.1007/s10433-022-00740-z., Competing Interests: Conflict of interestThe authors have no conflicts of interest to declare that are of relevance to the content of this article., (© The Author(s), under exclusive licence to Springer Nature B.V. 2022, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Purpose: Loneliness in adults increases with age. Although loneliness has been found to be associated with psychiatric disorders and dementia, no information is available on prevalence of loneliness in older psychiatric patients. The aims of this study were to examine prevalence of loneliness in older psychiatric outpatients, including gender differences and associations with psychiatric disorders and social isolation., Methods: Cross-sectional study in an outpatient clinic for geriatric psychiatry between September 2013 and February 2018. Interviews were done in 181 patients., Results: 80% of participants were lonely. Loneliness was associated with having contacts in less social network domains, in women but not in men. There were no associations with DSM-IV-TR-classifications. However, loneliness was associated with higher scores on questionnaires for depression and cognitive function. Intensity of treatment did not differ significantly between lonely and non-lonely participants., Conclusion: Loneliness is highly prevalent in older psychiatric outpatients, with men and women equally affected. Loneliness should be assessed in all older psychiatric patients, especially when they show high scores on symptom checklists or have a restricted social network.

Objectives: Polypharmacy and late-life depression often congregate in the geriatric population. The primary objective is to identify determinants of polypharmacy in patients with depression, and second to examine polypharmacy in relation to various clinical phenotypes of depression and its course., Methods: A longitudinal observational study using data of the Netherlands Study of Depression in Older persons (NESDO) including 375 patients with depression ≥ 60 years and 132 non-depressed comparisons. Linear and logistic regression were used to analyze both polypharmacy (dichotomous: ≥5 medications) and number of prescribed drugs (continuous) in relation to depression, various clinical phenotypes, and depression course., Results: Polypharmacy was more prevalent among patients with depression (46.9%) versus non-depressed comparisons (19.7%). A lower level of education, lower cognitive functioning, and more chronic diseases were independently associated with polypharmacy. Adjusted for these determinants, polypharmacy was associated with a higher level of motivational problems, anxiety, pain, and an earlier age of onset. A higher number of drugs was associated with a worse course of late-life depression (OR = 1.24 [95% CI: 1.03-1.49], p = 0.022)., Conclusion: Older patients with depression have a huge risk of polypharmacy, in particular among those with an early onset depression. As an independent risk factor for chronic depression, polypharmacy needs to be identified and managed appropriately. Findings suggest that depression moderates polypharmacy through shared risk factors, including motivational problems, anxiety, and pain. The complex interaction with somatic health burden requires physicians to prescribe medications with care., (© 2022 The Authors. Acta Psychiatrica Scandinavica published by John Wiley & Sons Ltd.)

Background: Loneliness and social isolation have both been found to be associated with increased mortality in previous studies. One potential underlying mechanism is via the hypothalamic-pituitary-adrenal axis., Objective: This study aimed to examine the association between social network size and cortisol, to analyze the associations between both loneliness and social network size and mortality, and to examine to what extent the association between network size and/or loneliness and mortality is mediated by cortisol., Design: The study group consisted of 443 depressed and non-depressed participants of the Netherlands Study of Depression in the Elderly (NESDO). Cross-sectional analysis of the association between social network size and cortisol measures was followed by a survival analysis of the associations between both social network size and loneliness and mortality., Results: There were no significant associations between social network size and cortisol measures. Loneliness and small social network size were not associated with mortality. Age and partner status were more important predictors of mortality., Conclusion: As people grow older the variety of factors that influence mortality risk increases, diminishing the effect of a single factor. Prevention of early morbidity and mortality in older adults should be tailored to specific needs and risks, instead of aiming at one specific factor.

Importance: In clinical guidelines, overt and subclinical thyroid dysfunction are mentioned as causal and treatable factors for cognitive decline. However, the scientific literature on these associations shows inconsistent findings., Objective: To assess cross-sectional and longitudinal associations of baseline thyroid dysfunction with cognitive function and dementia., Design, Setting, and Participants: This multicohort individual participant data analysis assessed 114 267 person-years (median, 1.7-11.3 years) of follow-up for cognitive function and 525 222 person-years (median, 3.8-15.3 years) for dementia between 1989 and 2017. Analyses on cognitive function included 21 cohorts comprising 38 144 participants. Analyses on dementia included eight cohorts with a total of 2033 cases with dementia and 44 573 controls. Data analysis was performed from December 2016 to January 2021., Exposures: Thyroid function was classified as overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism, subclinical hypothyroidism, and overt hypothyroidism based on uniform thyrotropin cutoff values and study-specific free thyroxine values., Main Outcomes and Measures: The primary outcome was global cognitive function, mostly measured using the Mini-Mental State Examination. Executive function, memory, and dementia were secondary outcomes. Analyses were first performed at study level using multivariable linear regression and multivariable Cox regression, respectively. The studies were combined with restricted maximum likelihood meta-analysis. To overcome the use of different scales, results were transformed to standardized mean differences. For incident dementia, hazard ratios were calculated., Results: Among 74 565 total participants, 66 567 (89.3%) participants had normal thyroid function, 577 (0.8%) had overt hyperthyroidism, 2557 (3.4%) had subclinical hyperthyroidism, 4167 (5.6%) had subclinical hypothyroidism, and 697 (0.9%) had overt hypothyroidism. The study-specific median age at baseline varied from 57 to 93 years; 42 847 (57.5%) participants were women. Thyroid dysfunction was not associated with global cognitive function; the largest differences were observed between overt hypothyroidism and euthyroidism-cross-sectionally (-0.06 standardized mean difference in score; 95% CI, -0.20 to 0.08; P = .40) and longitudinally (0.11 standardized mean difference higher decline per year; 95% CI, -0.01 to 0.23; P = .09). No consistent associations were observed between thyroid dysfunction and executive function, memory, or risk of dementia., Conclusions and Relevance: In this individual participant data analysis of more than 74 000 adults, subclinical hypothyroidism and hyperthyroidism were not associated with cognitive function, cognitive decline, or incident dementia. No rigorous conclusions can be drawn regarding the role of overt thyroid dysfunction in risk of dementia. These findings do not support the practice of screening for subclinical thyroid dysfunction in the context of cognitive decline in older adults as recommended in current guidelines.

Purpose: E-PsEYE is an internet-based, guided self-help course, following the principles of cognitive behavioural therapy, to reduce anxiety and depression in patients with retinal exudative diseases who receive anti-vascular endothelial growth factor (anti-VEGF) treatment. The purpose of this study was to determine the prevalence and related factors of anxiety and depression in this population and evaluate the usability and feasibility of E-PsEYE., Methods: Symptoms of anxiety and depression and related factors were determined in 90 patients (mean age 77 years, 58% female), based on multiple logistic regression analysis. Five patients with mild to moderate depression/anxiety tested the usability of E-PsEYE. They were asked to think aloud while completing two modules of the intervention and freely explore system features. The feasibility of the total E-PsEYE intervention was tested in 14 patients with mild to moderate depression/anxiety, based on a single arm pre-post study with a follow-up of three months: fidelity, acceptability, feasibility of study methods and potential effectiveness were explored., Results: Fifty-three percent of the total study population experienced at least mild anxiety and/or depression symptoms. Especially female patients (odds ratio (OR) 3.89, 95% confidence interval (CI) 1.33-11.40), those who experienced limitations in daily life activities due to vision loss (OR 9.67; 95% CI 3.18-29.45) and those who experienced loneliness (OR 3.53, 95% CI 1.14-10.95) were more likely to have anxiety/depression. The usability study raised several possibilities for improvement, based on which E-PsEYE was improved. The feasibility study showed adequate fidelity and acceptability. Most participants were satisfied with the results (79%). There was a high response rate, no loss to follow-up and mental health problems decreased in more than half of the patients. The Wilcoxon signed rank test indicated lower post-test ranks compared to pre-test ranks (depression Z -1.34, p = 0.18; anxiety Z -1.45, p = 0.15)., Conclusions: Mental health problems are prevalent in patients who receive anti-VEGF treatment. Healthcare providers should recognise these problems and related factors in order to refer patients to appropriate care in a timely manner. Outcomes on the usability and feasibility of E-PsEYE are promising as a prelude to performing a randomised controlled trial, which will shed more light on its (cost-)effectiveness., (© 2021 The Authors Ophthalmic and Physiological Optics published by John Wiley & Sons Ltd on behalf of College of Optometrists.)

Objective: Studies on the course of depression often ignore comorbid anxiety disorders or anxiety symptoms. We explored predictors of complete remission (no depression nor anxiety diagnoses at follow-up) and of the course of comorbid anxiety symptoms. We additionally tested the hypothesis that the course of anxiety disorders and symptoms in depressed patients is explained by negative life-events in the presence of high neuroticism or a low sense of mastery., Methods: An observational study of 270 patients (≥60 years) diagnosed with major depressive disorder and 2-year follow-up data, who participated in the Netherlands Study of Depression in Older persons (NESDO). Sociodemographic, somatic, psychiatric, and treatment variables were first explored as possible predictors. A multiple logistic regression analysis was used to examine their predictive value concerning complete remission. Subsequently, negative life-events, personality and their interaction were tested as potential predictors. Linear Mixed Models were used to assess whether the personality traits modified the effect of early and recent life-events, and time and their interactions on the course of the anxiety symptoms., Results: A total of 135 of 270 patients achieved complete remission. Depressed patients with a comorbid anxiety disorder at baseline less often achieved complete remission: 38 of 103 (37.0%) versus 97 of 167 (58.1%). The severity of depressive and anxiety symptomatology, the presence of a comorbid anxiety disorder, and a poorer physical health at baseline predicted nonremission. In line with our hypothesis, a less favorable course of self-reported anxiety symptoms was associated with more recent negative life-events, but only among patients with a high level of neuroticism or a low level of mastery., Conclusion: Comorbid anxiety in depression as a negative impact on complete remission at 2-year follow-up. The course of anxiety severity seems dependent on the interaction of personality traits and life-events., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

Objective: Frailty is a clinical phenotype that predicts negative health outcomes, including mortality, and is increasingly used for risk stratification in geriatric medicine. Similar to frailty, late-life depression is also associated with increased mortality rates. Therefore, we examined whether frailty and frailty-related biomarkers predict mortality among depressed older patients., Methods: In our study of 378 older patients aged ≥ 60 years with a depressive disorder (DSM-IV criteria), we examined whether frailty predicts time-to-death during a 6-year follow-up using Cox proportional hazard regression analyses adjusted for confounders. Baseline data were collected from 2007 to September 2010. Frailty was defined according to the Fried Frailty Phenotype criteria (muscle weakness, slowness, exhaustion, low activity level, unintended weight loss). Similarly, we examined the predictive value of 3 inflammatory markers, vitamin D level, and leukocyte telomere length and whether these effects were independent of the frailty phenotype., Results: During follow-up, 27 (26.2%) of 103 frail depressed patients died compared with 35 (12.7%) of 275 non-frail depressed patients (P < .001). Adjusted for confounders, the number of frailty components was associated with an increased mortality rate (hazard ratio = 1.38 [95% CI, 1.06-1.78], P = .015). All biomarkers except for interleukin 6 were prospectively associated with mortality, but only higher levels of high-sensitivity C-reactive protein and lower levels of vitamin D were independent of frailty associated with mortality., Conclusions: In late-life depression, frailty identifies older patients at increased risk of adverse negative health outcomes. Therefore, among frail depressed patients, treatment models that include frailty-specific interventions might reduce mortality rates., (© Copyright 2021 Physicians Postgraduate Press, Inc.)

Objective: Apathy symptoms are defined as a lack of interest and motivation. Patients with late-life depression (LLD) also suffer from lack of interest and motivation and previous studies have linked apathy to vascular white matter hyperintensities (WMH) of the brain in depressed and nondepressed patients. The aim of this study was to investigate the relationship between apathy symptoms, depressive symptoms, and WMH in LLD. We hypothesize that late-onset depression (LOD; first episode of depression after 55 years of age) is associated with WMH and apathy symptoms., Methods: Apathy scores were collected for 87 inpatients diagnosed with LLD. Eighty patients underwent brain magnetic resonance imaging. Associations between depressive and apathy symptoms and WMH were analyzed using linear regression., Results: All 3 subdomains of the 10-item Montgomery-Åsberg Depression Rating Scale correlated significantly with the apathy scale score (all P < .05). In the total sample, apathy nor depressive symptoms were related to specific WMH. In LOD only, periventricular WMH were associated with depression severity (β = 5.21, P = .04), while WMH in the left infratentorial region were associated with apathy symptoms (β coefficient = 5.89, P = .03)., Conclusion: Apathy and depressive symptoms are highly overlapping in the current cohort of older patients with severe LLD, leading to the hypothesis that apathy symptoms are part of depressive symptoms in the symptom profile of older patients with severe LLD. Neither apathy nor depressive symptoms were related to WMH, suggesting that radiological markers of cerebrovascular disease, such as WMH, may not be useful in predicting these symptoms in severe LLD.

We aimed to obtain reliable reference charts for sleep duration, estimate the prevalence of sleep complaints across the lifespan and identify risk indicators of poor sleep. Studies were identified through systematic literature search in Embase, Medline and Web of Science (9 August 2019) and through personal contacts. Eligible studies had to be published between 2000 and 2017 with data on sleep assessed with questionnaires including ≥100 participants from the general population. We assembled individual participant data from 200,358 people (aged 1-100 years, 55% female) from 36 studies from the Netherlands, 471,759 people (40-69 years, 55.5% female) from the United Kingdom and 409,617 people (≥18 years, 55.8% female) from the United States. One in four people slept less than age-specific recommendations, but only 5.8% slept outside of the 'acceptable' sleep duration. Among teenagers, 51.5% reported total sleep times (TST) of less than the recommended 8-10 h and 18% report daytime sleepiness. In adults (≥18 years), poor sleep quality (13.3%) and insomnia symptoms (9.6-19.4%) were more prevalent than short sleep duration (6.5% with TST < 6 h). Insomnia symptoms were most frequent in people spending ≥9 h in bed, whereas poor sleep quality was more frequent in those spending <6 h in bed. TST was similar across countries, but insomnia symptoms were 1.5-2.9 times higher in the United States. Women (≥41 years) reported sleeping shorter times or slightly less efficiently than men, whereas with actigraphy they were estimated to sleep longer and more efficiently than man. This study provides age- and sex-specific population reference charts for sleep duration and efficiency which can help guide personalized advice on sleep length and preventive practices.

Background: Age-related cognitive decline has large-scale functional and economic consequences and understanding its' pathophysiological mechanisms is therefore essential. Previous research has suggested associations between hormones adiponectin, ghrelin and leptin and neurodegenerative disease. However, their association with age-related cognitive decline has not been fully described. We examine the association between serum high-molecular-weight (HMW) adiponectin, ghrelin and leptin and age-related cognitive decline in older adults., Methods: The associations between HMW adiponectin, ghrelin and leptin and the Mini-Mental-State-Examination, Coding task (Coding), 15 Words Test (15WT) and composite Z-score (general cognitive function) were analyzed by means of a sex-stratified multivariable linear regression analysis in a population-based cohort of 898 older adults at baseline and after 3 years of follow-up., Results: In women, we found a positive association between HMW adiponectin and general cognitive function at baseline (fully adjusted model composite Z-score standardized regression co-efficient beta [β] = .089, p = .025). After 3 years of follow-up, HMW adiponectin was associated with more decline in general cognitive function and information processing speed (fully adjusted model composite Z-score β = -.123, p = .018; Coding β = -.116, p = .027). Ghrelin and leptin were significantly associated with memory in a baseline subgroup analysis of older women. For men, we found no significant associations at baseline or follow-up., Conclusion: Our results show variable associations between hormones HMW adiponectin, ghrelin and leptin and age-related cognitive decline in women but not in men. As there was no clear trend, all our results should be interpreted with caution., (© The Author(s) 2020. Published by Oxford University Press on behalf of The Gerontological Society of America.

Objectives: To examine the association of social network size and loneliness with cognitive performance and -decline in depressed older adults. Method: A sample of 378 older adults [70.7 (7.4) years] with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of current depressive disorder were recruited from primary care and specialized mental health care. Cognitive performance was assessed at baseline and 2 years follow-up with the Stroop colored-word test, a modified version of the Auditory Verbal Learning Task and the Digit Span subtest from the Wechsler Adult Intelligence Scale, encompassing four cognitive domains; processing speed, interference control, memory, and working memory. Social network size was assessed with the Close Person Inventory and loneliness with the de Jong Gierveld Loneliness Scale at baseline. Results: After adjusting for baseline working memory performance, loneliness was associated with impaired working memory after 2 years [B = -0.08 (-0.17 to 0.00)]. This association was no longer significant after adjusting for age, sex, education level, physical activity, alcohol use and depressive symptom severity [B = -0.07 (-0.16 to 0.03)]. A backward elimination procedure revealed education level to be the only covariable to explain this association. Loneliness was not associated with impairments or decline in other cognitive domains. Social network size was not associated with cognitive impairments or decline. Conclusion: Social network size and loneliness do not predict cognitive decline in depressed older adults.

Background: Anticholinergic and sedative medications are frequently prescribed to older individuals. These medications are associated with short-term cognitive and physical impairment, but less is known about long-term associations. We therefore examined whether over 20 years cumulative exposure to these medications was related to poorer cognitive and physical functioning., Methods: Older adult participants of the Longitudinal Aging Study Amsterdam (LASA) were followed from 1992 to 2012. On seven measurement occasions, cumulative exposure to anticholinergic and sedative medications was quantified with the drug burden index (DBI), a linear additive pharmacological dose-response model. Cognitive functioning was assessed with the Mini-Mental State Examination (MMSE), Alphabet Coding Task (ACT, three trials), Auditory Verbal Learning Test (AVLT, learning and retention condition), and Raven Colored Progressive Matrices (RCPM, two trials). Physical functioning was assessed with the Walking Test (WT), Cardigan Test (CT), Chair Stands Test (CST), Balance Test (BT), and self-reported Functional Independence (FI). Data were analyzed with linear mixed models adjusted for age, education, sex, living with a partner, BMI, depressive symptoms, comorbidities (cardiovascular disease, diabetes, cancer, COPD, osteoarthritis, CNS diseases), and prescribed medications., Results: Longitudinal associations were found of the DBI with poorer cognitive functioning (less items correct on the three ACT trials, AVLT learning condition, and the two RCPM trials) and with poorer physical functioning (longer completion time on the CT, CST, and lower self-reported FI)., Conclusions: This longitudinal analysis of data collected over 20 years, showed that higher long-term cumulative exposure to anticholinergic and sedative medications was associated with poorer cognitive and physical functioning., (© The Author(s) 2019.

Objective: Loneliness and social isolation have negative health consequences and are associated with depression. Personality characteristics are important when studying persons at risk for loneliness and social isolation. The objective of this study was to clarify the association between personality factors, loneliness and social network, taking into account diagnosis of depression, partner status and gender., Design: Cross-sectional data of an ongoing prospective cohort study, the Netherlands Study of Depression in Older Persons (NESDO), were used., Setting and Participants: 474 participants were recruited from mental health care institutions and general practitioners in five different regions in the Netherlands., Measurements: NEO-Five Factor Inventory (NEO-FFI) personality factors and loneliness and social network were measured as well as possible confounders. Multinominal logistic regression analyses were performed to analyse the associations between NEO-FFI factors and loneliness and social network. Interaction terms were investigated for depression, partner status and gender., Results: Higher neuroticism and lower extraversion in women and lower agreeableness in both men and women were associated with loneliness but not with social network size irrespective of the presence of depression. In the non-depressed group only, lower openness was associated with loneliness. Interaction terms with partner status were not significant., Conclusions: Personality factors are associated with loneliness especially in women. In men lower agreeableness contributes to higher loneliness. In non-depressed men and women, lower openness is associated with loneliness. Personality factors are not associated with social network size.

Objective: To study the association between vitamin D levels and frailty, its components and course in a depressed sample. Methods: Baseline and two-year follow-up data from the depressed sample of the Netherlands Study of Depression in Older persons (NESDO), a prospective observational cohort study, were analyzed. The 378 participants (aged 60-93) had a diagnosis of depression according to DSM-IV criteria. Frailty was defined according to Fried's physical phenotype. 25-OH vitamin D measurement was performed by liquid chromatography - tandem mass spectrometry. Linear and logistic regression analyses were performed, adjusted for covariates. Results: Higher vitamin D levels were cross-sectionally associated with lower prevalence of frailty (OR 0.64 [95%-CI 0.45 - 0.90], p = .010), predicted a lower incidence of frailty among non-frail depressed patients (OR 0.51 [95%-CI 0.26 - 1.00], p =.050), and, surprisingly, the persistence of frailty among frail depressed patients (OR 2.82 [95%-CI 1.23 - 6.49], p =.015). Conclusions: In a depressed population, higher vitamin D levels were associated with lower prevalence and incidence of frailty. Future studies should examine whether the favorable effect of low vitamin D levels on the course of frailty can be explained by confounding or whether unknown pathophysiological mechanisms may exert protective effects.

Background: Monitoring of trends in functioning of older adults provides indispensable information for health care policy. This study examined trends in multiple indicators of functioning among Dutch older adults across a period of 20 years., Methods: Data from the Longitudinal Aging Study Amsterdam were used. We included 10 870 observations of 3803 respondents aged 64-84 years across seven waves (1992-12) and 931 observations of 603 respondents aged 85-94 years across four waves (2001-12). At each wave, 8 indicators of functioning were measured: multimorbidity, severe functional limitations, depression, anxiety, cognitive impairment, physical inactivity, loneliness and social isolation. In addition, a sum score (range: 0-8) of these indicators was calculated, with a score of ≥5 indicating 'multiple problems.' Trends in functioning over time were assessed using Generalized Estimating Equation analyses., Results: In the 64-84-years-olds, the prevalence of multimorbidity increased over time [OR(year) = 1.06, 95% CI = 1.05-1.06], whereas the prevalence of the other indicators decreased [i.e. cognitive impairment, physical inactivity (in women) and loneliness (in women)] or remained stable [i.e. severe functional limitations, depression, anxiety, physical inactivity (in men), loneliness (in men) and social isolation]. In the 85-94-year-olds, the prevalence of severe functional limitations increased over time [OR(year) = 1.08, 95% CI = 1.02-1.13], whereas the prevalence of the other indicators remained stable. In both age groups, the prevalence of 'multiple problems' remained stable., Conclusion: Unfavorable trends were observed in multimorbidity among 64-84-years-olds and in severe functional limitations among 85-94-year-olds. Favorable trends were found in cognitive impairment, physical inactivity (in women) and loneliness (in women) among 64-84-years-olds., (© The Author(s) 2019.

Although previous studies have underlined the protective role of social support for physical and psychological health, no self-report questionnaires are validated for measuring social support in large-scale psychiatric epidemiological studies. In the current study, we aim to validate the shortened version of the Close Persons Questionnaire (CPQ), a self-report questionnaire that is administered twice to measure social support received from the partner (CPQ-p) as well as from a close friend/family member (CPQ-f). Data of psychiatric patients (n = 1891) and controls (n = 1872) from three Dutch epidemiological studies that assessed determinants of psychopathology were used to validate the shortened CPQ. This included determining factor structure and reliability for the different scales. Using multigroup confirmatory factor analyses, a four-factor model proved to be the best fitting model for both the CPQ-p and CPQ-f. The resulting subscales -emotional support, practical support, negative support experiences, inadequacy of support-showed moderate to good reliability for both the CPQ-p and the CPQ-f, and were all correlated with other social measures in the expected directions. The shortened version of the CPQ proves to be a valid and reliable measure of social support for both psychiatric patients and controls. Further research is needed to assess usability of the shortened version of the CPQ for clinical practice., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Objective: The aim of this article is to study the associations between healthy lifestyle in old age and decline in physical, psychological, cognitive, and social functioning. Method: A population-based sample of 3,107 Dutch men and women aged 55 and 85 years (1992/1993; Longitudinal Aging Study Amsterdam) was used with five 3-yeary follow-up examinations. Lifestyle score, based on smoking status, alcohol consumption, physical activity, and body mass index (BMI), ranged from 0 ( unhealthy ) to 4 ( healthy ). Outcomes included gait speed, depressive symptoms, cognitive status, and social contacts. Results: Persons with a healthy lifestyle had a 10.6% slower decline in gait speed (0.04 m/s, 95% confidence interval [CI] = [0.03, 0.05]), 10.8% slower increase in depressive symptoms (-1.07 [-1.70, -0.44]), a 1.8% slower decline in cognitive functioning (0.47 [0.23, 0.70]), and a 4.9% slower decline in social contacts (0.58 [0.01, 1.15]) compared with persons with no or one healthy lifestyle factor. Discussion: A healthy lifestyle benefits physical, psychological, cognitive, and social functioning up to very old age.

Background/objectives: Aging-related physiological changes like metabolic dysregulation and physical frailty are associated with depression and worsen its prognosis. Since central obesity is a key component of the metabolic syndrome and sarcopenia of physical frailty, we examined the association of sarcopenic obesity with depression cross-sectional and over time., Methods: Cohort study of depressed patients and a nondepressed comparison group., Setting: Primary and secondary mental health care., Participants: Three hundred seventy-eight older (≥60 y) depressed patients of which 285 were followed up at 2 years and 132 nondepressed persons participating in the Netherlands Study of Depression in Older (NESDO) persons., Measurements: Sarcopenic obesity was based on predefined cutoffs for both maximum handgrip strength (assessed with a dynamometer) and waist circumference (dichotomous) as well as the product term of handgrip strength by waist circumference (dimensional). Depressive disorder according to DSM-IV-TR criteria was assessed with fully structured psychiatric interview at baseline and 2-year follow-up., Results: Sarcopenic obesity was more prevalent among depressed patients compared with nondepressed participants (18.9% versus 10.7%, P = 0.030). Neither the dichotomous nor dimensional operationalization of sarcopenic obesity was associated with baseline depressive disorder when adjusted for covariates. Nonetheless, among depressed patients, logistic regression showed that the interaction of handgrip strength by waist circumference was associated with remitted depression at 2-year follow-up (P = 0.044). Only among patients with a low handgrip strength, a higher waist circumference predicted nonremission., Conclusion: Among depressed patients, sarcopenic obesity predicts nonremission of depression. Therefore, combined exercise and nutritional interventions might be effective for depressed patients with sarcopenic obesity., (© 2019 John Wiley & Sons, Ltd.)

Background: Brain-derived neurotrophic factor (BDNF) levels decline during depression and normalise after remission, although studies in older patient samples are inconsistent. Whether BDNF serum levels predict depression remission is unclear. We hypothesize that the predictive value of serum BDNF levels in late-life depression is moderated by selective serotonin reuptake inhibitors (SSRI) usage and early traumatization., Methods: Our study sample was a subset of the Netherlands Study of Depression in Older persons (NESDO), a prospective cohort study. It consisted of 267 older persons with a diagnosis of depression, for which follow-up data were available. Depression diagnosis was assessed at baseline and follow up using a structured diagnostic interview (Composite International Diagnostic Interview (CIDI), volume2.1). Logistic regression was performed (adjusted for covariates) with remission of depression after two years as the dependent variable and baseline BDNF serum levels, childhood traumatization and SSRI use as independent variables. Results - The mean age of the subjects was 70.7 years, 65.6% of them were female, their mean BDNF level was 7.7 ng/ml, 80 (30.0%) of them were traumatised in their childhood,71 (26.6%) used SSRIs and 136 (50.9%) no longer had a depressive disorder at the two year follow up. The predictive value of BDNF serum levels was conditional on traumatization and SSRI usage (threeway interaction p = .010). Higher BDNF serum levels predicted remission in traumatized depressed patients without SSRI usage (OR = 1.17, 95% C.I.: 1.00-1.36; p = .048) and in non-traumatized depressed patients who used SSRIs (OR = 1.17, 95% C.I.: 1.00-1.36; p = .052), but not in the other two subgroups., Conclusion: The association between BDNF serum levels and the course of late-life depression seems to depend on SSRI use and childhood trauma. Based on these results, we hypothesize that childhood trauma may permanently reduce ('blunt') the responsiveness of the neurotrophic system to SSRI usage, and that this responsiveness might be more important for depression course than the actual BDNF serum levels., (Copyright © 2019 The Authors.

Purpose Various directional hypotheses for the observed links between aging, hearing, and cognition have been proposed: (a) cognitive load on perception hypothesis, (b) information degradation hypothesis, (c) sensory deprivation hypothesis, and (d) common cause hypothesis. Supporting evidence for all 4 hypotheses has been reported. No studies have modeled the corresponding 4 causal pathways into 1 single model, which would be required to evidence that multiple directional hypotheses apply. The aim of the current study was to tease out which pathways apply for 5 different cognitive measures. Method Data from 1,029 respondents of the Longitudinal Aging Study Amsterdam were used spanning a maximum follow-up of 7 years (3 measurements). Speech-in-noise recognition ability (digit triplet speech-in-noise test) was included as a measure of auditory function. Cognitive measures included global cognitive functioning, fluid intelligence, information processing speed, and verbal memory (immediate recall and retention). Bivariate dual change score modeling was used to model the causal pathways between hearing, cognition, and baseline age. Results For information processing speed, global cognitive functioning, fluid intelligence, and memory-immediate recall, all pathways except for the sensory deprivation pathway were supported. For memory-retention, only the common cause and the sensory deprivation pathways were supported. Conclusions Causal pathways corresponding to all 4 hypotheses were supported. Support for the common cause hypothesis, the information degradation hypothesis, and the cognitive load on perception hypotheses was found for 4 of 5 cognitive measures. This was unexpected in some cases (e.g., support for the information degradation pathway for cognitive measures that do not rely on auditory stimuli). The sensory deprivation pathway that emerged for memory-retention might point toward processes related to early stages of dementia. In summary, the results show that the links between decline in auditory function, cognition, and aging are complex and most likely are captured by pathways belonging to various directional hypotheses.

Objectives: Older age and major depressive disorder (MDD) are both risk factors for the development of cardiovascular diseases. Testosterone has been associated with MDD and metabolic syndrome (MetS) in men, although associations in women are less clear. Therefore, we investigated whether testosterone is associated with MetS and whether this association is different for depressed and non-depressed older men and women., Methods: In this prospective cohort study, 478 participants (349 patients with MDD and 129 controls) aged between 60 and 93 years from the Netherlands Study of Depression in Older Persons were included. Total testosterone (TT) and sex-hormone binding globulin levels were measured using a second-generation radioimmune assay. Free testosterone (FT) was calculated based on TT. MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria., Results: A higher risk for MetS was found in men with low FT and TT (odds ratio [OR]: 0.67, 95% confidence interval [95%CI]: 0.47-0.95 and OR: 0.51, 95%CI: 0.34-0.75), and in women with high FT (OR: 1.41, 95%CI: 1.08-1.82). Strong associations in the same direction were found with adiposity, glucose, and plasma lipid MetS components at baseline, but not with changes in these components at 2-year follow-up. The associations did not significantly differ between MDD patients and controls., Conclusions: Independently of having MDD, low testosterone levels in men and, in contrast, high testosterone levels in women were significantly associated with MetS and its components., (© 2018 The Authors.

Objectives: To establish the course of metabolic syndrome (MS) rates in older patients with severe mental illness (SMI) after 5-year follow-up and evaluate whether MS at baseline is associated with mortality or diabetes at follow-up., Methods: Patients (>60 years of age) with SMI (N = 100) were included at a specialized mental health outpatient clinic. Metabolic parameters were collected from patients' medical files at baseline and after 5-year follow-up., Results: Follow-up data were available of 98 patients (98%); nine patients had died. Parameters of MS were available of 76 patients; 34.2% were diagnosed with MS. This was not significantly different compared with baseline (46.1%). MS at baseline was not significantly associated with mortality or development of diabetes at follow-up., Conclusions: In older patients with SMI, the rates of MS may reach a plateau. Screening for MS in older patients treated at a specialized mental health outpatient clinic may generate attention for their somatic health and treatment for the components of MS that may in turn have a positive effect on their outcome. However, further research with larger sample sizes is needed in order to confirm these findings., (© 2018 John Wiley & Sons, Ltd.)

Aims: Studying birth-cohort differences in depression incidence and their explanatory factors may provide insight into the aetiology of depression and could help to optimise prevention strategies to reduce the worldwide burden of depression., Methods: Data were used from the Longitudinal Aging Study Amsterdam, a nationally representative study among community dwelling older adults in the Netherlands. Cohort differences in depression incidence over a 10-year-period (score ⩾16 on the Center for Epidemiologic Studies Depression scale) were tested using a cohort-sequential-longitudinal-design, comparing two identically measured cohorts of non-depressed 55-64-year-olds, born 10-years apart. Baseline measurements took place in 1992/93 (early cohort, n = 794), and 2002/03 (recent cohort, n = 771). As indicated by the dynamic equilibrium model of depression, potential explanatory factors were distinguished in risk and protective factors., Results: The incidence rates for depression in the early and recent cohort were 1.91 (95% confidence interval (CI) 1.59-2.27) and 1.60 (95% CI 1.31-1.94) per 100 person-years, respectively. A 29% risk reduction in depression incidence was observed in the recent cohort (HRcohort: 0.71, 95% CI 0.54-0.92, p = 0.011), as compared with the early cohort, even though average levels of risk factors such as chronic disease and functional limitations had increased. This reduction was primarily explained by increased levels of education, mastery and labour market participation., Conclusions: These findings suggest that favourable developments of protective factors have counterbalanced unfavourable effects of risk factors on the incidence of depression, resulting in a net reduction of depression incidence among young-old adults. However, maintaining a good physical health must be a priority to further decrease depression rates.

Objective: Different biological mechanisms may underlie depression beginning in early life (early-onset) and depression beginning later in life (late-onset). Although the relation between inflammation and depression has been studied extensively, the distinct role of inflammation in early and late-onset depression in older patients has not been addressed before. In the cross-sectional part of this study, we explored differences in levels of circulating inflammatory markers and cytokine levels in lipopolysaccharide (LPS) stimulated whole blood between older subjects with a late-life onset depression (≥60 years) and older subjects with an early-onset depression (<60 years). Secondly, in a 2-year follow-up study, we examined if circulating and stimulated inflammatory markers influenced the change in Inventory of Depressive Symptomatology (IDS) scores, and if this relation was different for early- and late-onset depression., Methods: The study was part of the Netherlands Study of Depression in Older Persons (NESDO). We included 350 patients, all aged 60 and older, with a depressive episode in the previous 6 months: 119 with a late-onset depression and 231 with an early-onset depression. Blood samples were collected and CRP, IL-6, NGAL, GDF15, and, LPS plasma levels were determined and whole blood was LPS stimulated and cytokine levels IL-1β, IL-6, TNFα, IFNγ, IL-10, and IL-1 receptor antagonist (IL-1ra) were determined., Results: After adjustment for demographics, health indicators, and medication use, increased plasma CRP levels were more strongly associated with late-onset depression than early-onset depression (OR [95% CI]: 1.43 [1.05-1.94]). In the longitudinal analyses, higher circulating IL-6 levels were associated with a significantly slower decline in IDS scores in the crude and the adjusted models (p ≤ 0.027). This relation was not different between late- and early-onset depression. Other circulating and stimulated inflammatory markers were not associated with late- and/or early-onset depression., Conclusions: This study provides preliminary evidence that low-grade inflammation is more strongly associated with late-onset than early-onset depression in older adults, suggesting a distinct inflammatory etiology for late-onset depression. Cytokine production capacity did not distinguish between early- and late-onset depression., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Objectives: To examine 23-year trends in both physically and cognitively healthy life expectancy from age 65 years in the Netherlands., Methods: We used 8 waves between 1993 and 2016 from the nationally representative Longitudinal Aging Study Amsterdam (12 948 observations). We calculated physically and cognitively healthy life expectancies by using the Sullivan life table method and tested prevalence trends over time by using generalized estimating equations., Results: Total life expectancy at age 65 years rose from 14.7 to 18.7 years (men) and from 19.2 to 21.4 years (women). Life expectancy in poor physical health increased nonlinearly from 1.8 to 2.9 years for men; for women it fluctuated around 5.7 years. Meanwhile, life expectancy in good cognitive health increased linearly from 11.0 to 15.7 years (men) and from 13.4 to 18.0 years (women). The proportion of people with poor physical and poor cognitive health combined did not increase, averaging 5.9% (men) and 8.7% (women)., Conclusions: This multiwave study shows that a negative trend in physically healthy life expectancy is accompanied by a positive trend in cognitively healthy life expectancy.

Objectives: Depressive symptoms and low vitamin D status are common in older persons and may be associated, but findings are inconsistent. This study investigated whether 25-hydroxyvitamin D (25(OH)D) concentrations are associated with depressive symptoms in older adults, both cross-sectionally and longitudinally. We also examined whether physical functioning could explain this relationship, to gain a better understanding of the underlying mechanisms., Methods: Data from two independent prospective cohorts of the Longitudinal Aging Study Amsterdam were used: an older cohort (≥65 years, n = 1282, assessed from 1995-2002) and a younger-old cohort (55-65 years, n = 737, assessed from 2002-2009)., Measurements: Depressive symptoms were measured at baseline and after 3 and 6 years with the Center of Epidemiological Studies Depression Scale. Cross-sectional and longitudinal linear regression techniques were used to examine the relationship between 25(OH)D and depressive symptoms. The mediating role of physical functioning was examined in the longitudinal models., Results: Cross-sectionally, associations were not significant after adjustment for confounders. Longitudinally, women in the older cohort with baseline 25(OH)D concentrations up to 75 nmol/L experienced 175 to 24% more depressive symptoms in the following 6 years, compared with women with 25(OH)D concentrations >75 nmol/L. Reduced physical performance partially mediated this relationship. In men and in the younger-old cohort, no significant associations were observed., Conclusions: Older women showed an inverse relationship between 25(OH)D and depressive symptoms over time, which may partially be explained by declining physical functioning. Replication of these findings by future studies is needed., (Copyright © 2018 American Association for Geriatric Psychiatry. Published by Elsevier Inc. All rights reserved.)

Controversy exists concerning the reliability of retrospective self-reports on childhood abuse since this method might be subject to under- or overreporting. Until now, no studies have been done in older adults, although reasons for under- or overreporting could be even more prominent in this age group. In this first study in older adults, test-retest reliability of retrospective measurements on childhood abuse and the influence of age, cognitive functioning and depression on this test-retest reliability was investigated. A longitudinal cohort study, the Netherlands Study of Depression in Older persons (NESDO), obtained information on childhood abuse at baseline and at a 6-year follow-up interview. Our sample consisted of 277 adults (mean age 68.5 years at baseline) of which 118 (42.6%) reported childhood abuse at baseline. The largest proportion of the answers was consistent (yes-yes or no-no) for every type of childhood abuse, varying from 85.2 to 93.5%. Looking more closely, 'yes' answers were more fluctuating than 'no' answers. Sexual abuse was most reliably reported in two separate interviews. There was no significant effect of age nor cognition on the test-retest reliability. Only test-retest reliability of emotional neglect was significantly associated with depression diagnosis and depression severity at baseline. In conclusion, test-retest reliability of retrospective self-reports on childhood abuse seems moderate to good, but slightly dependent on the type of abuse. The test-retest reliability was influenced neither by age nor cognition, only reporting of emotional neglect was associated with depression state., (Copyright © 2018 Elsevier Ltd.

Objectives: Functional limitations give an indication of the total impact of diseases, such as depression, on individuals health and recovery. This study examines the change in several domains of functioning over 2 years in older persons depressed at baseline (non-remitted group and remitted group after 2 years) and in a non-depressed comparison group., Methods: Data were used from a cohort study (Netherlands Study of Depression in Older persons [NESDO]) consisting of depressed older persons ≥ 60 years (N = 378) and a non-depressed comparison group (N = 132) with 2 years of follow-up (attrition rate 24%). Functional limitations (outcome) were assessed with the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) questionnaire every 6 months. Total scores and domain scores were used. Depression was classified according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria at baseline and at 2-year follow-up. Severity of depression (predictor) was assessed with the Inventory of Depressive Symptomatology (IDS) at 6-month intervals., Results: Linear mixed models showed that the level of functional limitations differed between the three groups during 2 years of follow-up. The non-remitted group had the highest level of functional limitations during 2 years, followed by the remitted group. Stable low levels of functional limitations were found for the non-depressed group. Remission from depression was accompanied by improvements in functioning, however, compared to the non-depressed comparison group significant functional limitations remained. Higher severity of depression appeared as risk factor for a declining course of functioning, especially the social aspects of functioning., Methodological Considerations: Participants that were more severely depressed and more functionally impaired at baseline had higher attrition rates than the participants that were included in the analytical sample., Conclusion: This study showed that depression in later life has long-term debilitating effects on functioning, enduring even after remission from depression. This implies that depression treatment in later life should aim broader than just symptomatic recovery, but also include functional recovery.

Background: Although average life-expectancy is still increasing worldwide, ageing processes markedly differ between individuals, which has stimulated the search for biomarkers of biological ageing., Objectives: Firstly, to explore the cross-sectional and longitudinal association between leucocyte telomere length (LTL) as molecular marker of ageing and the physical frailty phenotype (PFP) as a clinical marker of ageing and secondly, to examine whether these associations are moderated by the presence of a depressive disorder, as depression can be considered a condition of accelerated ageing., Methods: Among 378 depressed older patients (according to DSM-IV criteria) and 132 non-depressed older persons participating in the Netherlands Study of Depression in Older persons, we have assessed the physical frailty phenotype and LTL. The PFP was defined according to Fried's criteria and its components were reassessed at two-year follow-up., Results: LTL was neither associated with the PFP at baseline by Spearman rank correlation tests, nor did it predict change in frailty parameters over a two-year follow-up using regression analyses adjusted for potential confounders., Conclusion: LTL is not associated with frailty; neither in non-depressed nor in depressed older persons. As LTL and physical frailty appear to represent different aspects of ageing, they may complement each other in future studies., (Copyright © 2018. Published by Elsevier Inc.)

Objectives: Childhood abuse has been associated with depression in later life. This may be related to hypothalamic-pituitary-adrenal (HPA) axis functioning. Therefore we aimed to examine the impact of childhood abuse and its interaction with depression on cortisol levels in older adults., Methods: Data from 418 participants (mean age 70.8 years) in the Netherlands Study of Depression in Older Persons (NESDO) were used; 187 participants experienced childhood abuse; 309 participants had a diagnosis of depression. Diurnal cortisol levels were determined using six saliva samples from every participant. Multiple regression analyses were performed., Results: Significant negative associations between childhood abuse and morning cortisol levels were found. In nondepressed persons, both psychological and sexual abuse were associated with greater dynamics of the HPA axis in response to awakening., Conclusions: Childhood abuse is associated with lower basal cortisol levels at awakening irrespective of major depressive disorder (MDD). Higher reactivity of the HPA axis during the hour after awakening was found in nondepressed participants only, which might suggest that late-life depression modifies the effect of childhood abuse on the HPA axis. Older adults with a history of childhood abuse may be more negatively affected by stress or stressful events and this is reflected in dysregulation of the HPA axis.

Objectives: To examine the six-year prognosis of patients with late-life depression and to identify prognostic factors of an unfavorable course., Design and Setting: The Netherlands Study of Depression in Older Persons (NESDO) is a multisite naturalistic prospective cohort study with six-year follow-up., Participants: Three hundred seventy-eight clinically depressed patients (according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision criteria) and 132 nondepressed comparisons were included at baseline between 2007 and 2010., Measurements: Depression was measured by the Inventory of Depressive Symptomatology at 6-month intervals and a diagnostic interview at 2- and 6-year follow-up. Multinomial regression and mixed model analyses were both used to identify depression-related clinical, health, and psychosocial prognostic factors of an unfavorable course., Results: Among depressed patients at baseline, 46.8% were lost to follow-up; 15.9% had an unfavorable course, i.e., chronic or recurrent; 24.6% had partial remission; and 12.7% had full remission at six-year follow-up. The relative risk of mortality in depressed patients was 2.5 (95% confidence interval 1.26-4.81) versus nondepressed comparisons. An unfavorable course of depression was associated with a younger age at depression onset; higher symptom severity of depression, pain, and neuroticism; and loneliness at baseline. Additionally, partial remission was associated with chronic diseases and loneliness at baseline when compared with full remission., Conclusions: The long-term prognosis of late-life depression is poor with regard to mortality and course of depression. Chronic diseases, loneliness, and pain may be used as putative targets for optimizing prevention and treatment strategies for relapse and chronicity., (Copyright © 2018 American Association for Geriatric Psychiatry.

Background: Risk factors for cognitive decline might depend on chronological age. The aim of the study was to explore the age dependency of risk factors for cognitive decline in cognitively healthy subjects aged 55-85 years at baseline., Methods: We included 2527 cognitively healthy subjects from the Longitudinal Aging Study Amsterdam (LASA). Median follow-up was 9.1 (IQR: 3.2-19.0) years. The association of genetic and cardiovascular risk factors, depressive symptoms, inflammation markers and lifestyle risk factors with decline in MMSE and memory function was tested using spline regression analyses., Results: Subjects were on average 70.1 (SD 8.8) years old at baseline. Based on a spline regression model, we divided our sample in three age groups: ≤70 years (young-old), > 70-80 years (old) and > 80 years (oldest-old). The association of LDL cholesterol, homocysteine, hypertension, history of stroke, depressive symptoms, interleukin-6, a1-antichymotrypsin, alcohol use and smoking with cognitive decline significantly differed between the age groups. In general, the presence of these risk factors was associated with less cognitive decline in the oldest-old group compared to the young-old and old group., Conclusions: The negative effect of various risk factors on cognitive decline decreases with higher age. A combination of epidemiological factors, such as the selection towards healthier subjects during follow-up, but also risk factor specific features, for example ensuring the cerebral blood flow in case of hypertension, explain this diminished association at higher age. It is important to take these age differences into account when applying preventive strategies to avert cognitive decline.

Background: Studying secular trends in the exposure to risk and protective factors of depression and whether these trends are associated with secular trends in the prevalence of depression is important to estimate future healthcare demands and to identify targets for prevention., Methods: Three birth cohorts of 55-64-year olds from the population-based Longitudinal Aging Study Amsterdam were examined using identical methods in 1992 (n = 944), 2002 (n = 964) and 2012 (n = 957). A two-stage screening design was used to identify subthreshold depression (SUBD) and major depressive disorder (MDD). Multinomial logistic regression analyses were used to identify secular trends in depression prevalence and to identify factors from the biopsychosocial domains of functioning that were associated with these trends., Results: Compared with 1992, MDD became more prevalent in 2002 (OR 1.90, 95% CI 1.10-3.28, p = 0.022) and 2012 (OR 1.80, 95% CI 1.03-3.14, p = 0.039). This was largely attributable to an increase in the prevalence of chronic diseases and functional limitations. Socioeconomic and psychosocial improvements, including an increase in labor market participation, social support and mastery, hampered MDD rates to rise more and were also associated with a 32% decline of SUBD-rates in 2012 as compared with 2002 (OR 0.68, 95% CI 0.48-0.96, p = 0.03)., Conclusions: Among late middle-aged adults, there is a substantial net increase of MDD, which is associated with deteriorating physical health. If morbidity and disability continue to increase, a further expansion of MDD rates may be expected. Improving socioeconomic and psychosocial conditions may benefit public health, as these factors were protective against a higher prevalence of both MDD and SUBD.

Background: Given the poor prognosis of late-life depression, it is crucial to identify those at risk. Our objective was to construct and validate a prediction rule for an unfavourable course of late-life depression., Methods: For development and internal validation of the model, we used The Netherlands Study of Depression in Older Persons (NESDO) data. We included participants with a major depressive disorder (MDD) at baseline (n = 270; 60-90 years), assessed with the Composite International Diagnostic Interview (CIDI). For external validation of the model, we used The Netherlands Study of Depression and Anxiety (NESDA) data (n = 197; 50-66 years). The outcome was MDD after 2 years of follow-up, assessed with the CIDI. Candidate predictors concerned sociodemographics, psychopathology, physical symptoms, medication, psychological determinants, and healthcare setting. Model performance was assessed by calculating calibration and discrimination., Results: 111 subjects (41.1%) had MDD after 2 years of follow-up. Independent predictors of MDD after 2 years were (older) age, (early) onset of depression, severity of depression, anxiety symptoms, comorbid anxiety disorder, fatigue, and loneliness. The final model showed good calibration and reasonable discrimination (AUC of 0.75; 0.70 after external validation). The strongest individual predictor was severity of depression (AUC of 0.69; 0.68 after external validation)., Limitations: The model was developed and validated in The Netherlands, which could affect the cross-country generalizability., Conclusions: Based on rather simple clinical indicators, it is possible to predict the 2-year course of MDD. The prediction rule can be used for monitoring MDD patients and identifying those at risk of an unfavourable outcome., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Objectives: Cognitive decline happens to everyone when aging, but to some more than others. Studies with children, adults, and professional musicians suggest that making music could be associated with better cognitive functioning. In older adults however, this association is less well investigated, which is therefore the aim of this study., Methods: In this cross-sectional study data from 1101 participants aged 64 and older from the Longitudinal Aging Study Amsterdam were used. Multivariable linear regression analyses were performed to test the association between making music and cognitive functioning and time spent making music and cognitive functioning. ANCOVA analyses were performed to differentiate between participants who made no music, only sang, only played an instrument or both sang and played an instrument in terms of cognitive functioning., Results: Making music was significantly positively associated with letter fluency, learning and attention/short-term memory. Time spent making music yielded no significant results. The ANCOVA analyses showed higher scores for participants who only played an instrument compared to participants who made no music on learning, working memory and processing speed. For processing speed the instrument only group also had a higher score than participants who only sang., Discussion: Making music at least once every two weeks and especially playing a musical instrument, is associated with better attention, episodic memory and executive functions. The results suggest that making music might be a potential protective factor for cognitive decline; however, to support this notion a longitudinal study design is needed.

Background: Older age patients with bipolar disorder (OABD) have often passive coping styles, generally considered as detrimental for functioning. The aim of the current study is to identify the contribution of cognitive functioning, subjective cognitive complaints and mood symptoms to passive and active coping styles in older age BD., Methods: In 90 euthymic patients (age > 60) with BD I or II, we examined coping, neuropsychological profile including memory, attention, executive function and fluency, subjective cognitive complaints and mood symptoms., Results: Better executive functioning and fewer depressive symptoms were associated with more active coping (p = .02 and p = .001 respectively). Associations between executive functioning and coping styles turned nonsignificant when combined with depressive symptoms in one model, indicating the importance of mood on coping styles. No associations were found between subjective cognitive complaints and coping styles., Limitations: Cross-sectional data were used and no conclusions about causality can be made., Conclusions: Even in euthymic patients, subclinical depressive symptoms may influence active coping negatively. Subjective cognitive complaints and objectified cognitive functioning seem to be of less importance for coping styles. Important implications are on the one hand optimizing treatment on reducing depressive symptoms and on the other hand focusing therapeutic interventions on coping in bipolar patients., (Copyright © 2018 Elsevier B.V.
