Depression in older adults erodes their health, quality of life and the economy. Existing interventions are not feasible for broad application at the community. Postcard intervention only requires a few resources, and previous studies have shown its effectiveness for patients following drug overdose, self-harm and hospitalisation for major depression. The purpose of the present study is to evaluate the effectiveness of a postcard intervention. Participants were community-dwelling individuals, aged 65 or older, who eat meals alone and with the score of 4 or higher on the 15-item Geriatric Depression Scale (GDS-15). We enrolled 184 eligible participants, with 93 in the intervention and 91 in the control arm. Postcards were sent to participants once a month for eight months. Primary outcome was the GDS-15 score at post-intervention. Secondary outcomes were quality of life and activities of daily living. There was no significant difference in primary and secondary outcomes between completers of the intervention and the control arm. However, most of the participants who received intervention thought the intervention was effective. The postcard intervention for depression in community-dwelling elderly people in Japan is neither feasible nor effective. However, the descriptive results suggest that the intervention may be effective given different parameters., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

Risk perception is one of the core factors in theories of health behavior promotion. However, the association between knowledge, risk perception, and depressed mood in depression is unknown. The aim of this study was to clarify the relationships between subjective knowledge, risk perception, and objective scores of depression in community-dwelling elderly people in Japan. A total of 747 elderly participants (mean age: 76.1, female: 59.8%) who completed the 15-item Geriatric Depression Scale (GDS-15) along with items assessing subjective knowledge and risk perception were included in the analysis. We assessed the correlation between subjective knowledge and risk perception, and then compare GDS-15 scores by level of subjective knowledge and risk perception. Subjective knowledge was weakly associated with risk perception and related to lower GDS-15 scores in a dose-response pattern, which did not change after adjusting for age, gender, basic activities of daily living (ADL), instrumental ADL, years of education and history of depression. There was no significant association between risk perception and GDS-15 scores. The relationship between knowledge, risk perception, and depressed mood in younger generations is unclear, but warrants examination., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

The objective of this study is to investigate the cross-cultural relationship between depressive state and subjective economic status, as well as subjective quality of life (QOL) and activities of daily living (ADL) among elderly people in communities in Japan, Taiwan, and Korea. We studied 595 subjects aged 65 years or older in three Asian communities (261 subjects in T town in Japan, 164 in D town in Taiwan, and 170 in H town in Korea). The Geriatric Depression Scale-15, a self-rating questionnaire assessing ADL, subjective QOL, social situations, and past and current medical status, was used. Depression of the elderly was associated with dependence in basic ADL, subjective QOL, and subjective sense of low economic status. After adjusting for the effects of age, sex, and basic ADL, subjective sense of low economic status was closely associated with depression in community-living elderly people in all three communities in Asia. In conclusion, absolute and objective economic status is an important contributing factor to depressive state or psychosocial deterioration, however, we should pay more attention to the roles of perception of low economic status in determining depressive state in community-dwelling elderly people., (Copyright © 2014 Elsevier Ireland Ltd.

Background: Missing data are inevitable in almost all medical studies. Imputation methods using the probabilistic model are common, but they cannot impute individual data and require special software. In contrast, the ipsative imputation method, which substitutes the missing items by the mean of the remaining items within the individual, is easy and does not need any special software, but it can provide individual scores. The aim of the present study was to evaluate the validity of the ipsative imputation method using data involving the 15-item Geriatric Depression Scale., Methods: Participants were community-dwelling elderly individuals (n = 1178). A structural equation model was constructed. The model fit indexes were calculated to assess the validity of the imputation method when it is used for individuals who were missing 20% of data or less and 40% of data or less, depending on whether we assumed that their correlation coefficients were the same as the dataset with no missing items. Finally, we compared path coefficients of the dataset imputed by ipsative imputation with those by multiple imputation., Results: When compared with the assumption that the datasets differed, all of the model fit indexes were better under the assumption that the dataset without missing data is the same as that that was missing 20% of data or less. However, by the same assumption, the model fit indexes were worse in the dataset that was missing 40% of data or less. The path coefficients of the dataset imputed by ipsative imputation and by multiple imputation were compatible with each other if the proportion of missing items was 20% or less., Conclusion: Ipsative imputation appears to be a valid imputation method and can be used to impute data in studies using the 15-item Geriatric Depression Scale, if the percentage of its missing items is 20% or less., (© 2014 The Authors.

We investigated the 15-item Geriatric Depression Scale (GDS-15) with regard to its factors and, reproducibility, as well as its relationship to activities of daily living, social factors, medical conditions, and quality of life for community-dwelling elderly people in Japan. The study population consisted of 736 community-dwelling elderly participants aged 65 or older. Exploratory factor analysis of the data and correlation coefficients between factors and activities of daily living, quality of life, social factors, and medical conditions were calculated for two consecutive years. The reproducibility of the results was also evaluated. As the result, GDS-15 had three reproducible factors specified as follows: factor I, "energy loss and pessimistic outlook"; factor II, "positive mental status (reversed)"; and factor III, "empty feeling." Comparing our findings with a review of research in this area, positive items (excluding "feel full of energy") seem to compose an universal factor. Factor I correlated best with quality of life, factor II with activities of daily living, and factor III with subjective cognitive function. These results suggest the GDS-15 can be used to assess the functional ability and quality of life, as well as depressive mood in older adults., (Copyright © 2013 Elsevier Ireland Ltd.

Background: Depression in older adults deteriorates quality of life and increases morbidity, mortality, and medical expenses. Medicine and social policy should work together to decrease this burden. Existing prevention studies are often based on time-consuming psychotherapies, which therefore are not feasible for a wide application at the community level. Postcard interventions have been shown to be effective for patients after hospitalization for major depression, drug overdose, or self-harm. This paper describes the protocol of a pragmatic, randomized controlled trial designed to examine the efficacy of a postcard intervention for depression among community-dwelling individuals aged 65 years or older., Methods/design: This is a pragmatic, non-blinded, parallel comparison, randomized controlled trial using Zelen's design in a community setting. Participants will include community-dwelling older adults (aged 65 years or older) with limited social support (indicated by eating meals alone) and with symptoms of depression (scoring 4 or higher on the 15-item Geriatric Depression Scale (GDS)). The intervention will consist of sending postcards with handwritten messages and seasonal reports from a historical city to participants once a month for eight consecutive months. Self-addressed, stamped envelopes will be enclosed to facilitate non-obligatory replies. Primary outcomes will be changes in the GDS scores that are administered to all elderly inhabitants of the community every year as part of annual health checks. Secondary outcomes include quality of life as measured by a visual analogue scale, and self-rated basic and advanced activities of daily living. We will also examine the subjective sense of effectiveness of the intervention, recollection of the number of intervention mailings received, and the number of mailed replies as the index of the acceptability of the postcard intervention. The time × group interaction for two consecutive years will be analyzed using a generalized linear mixed model. To detect an effect size of 0.5 at alpha error of 0.05 and statistical power of 0.80, 63 participants per group are required. Based on an estimated consent and dropout rate of 70%, a total of 180 subjects will be recruited., Trial Registration: UMIN000010529.

Aim: The aim of this study was to assess chewing ability using color-changeable chewing gum and to show the association between chewing ability and geriatric functions, as well as dietary status in the community-dwelling elderly., Methods: The study population consisted of 269 community-dwelling elderly aged ≥ 75 living in Tosa, Japan. Assessment of chewing ability was carried out by a dentist using color-changeable chewing gum. Activities of daily living (ADL), depression and subjective quality of life (QOL) were assessed by questionnaire. Cognitive status was assessed by; Mini-Mental State Examination (MMSE), Hasegawa Dementia Scale-Revised (HDS-R) and Frontal Assessment Battery (FAB) during the check-up. Food diversity was assessed using the 11-item Food Diversity Score Kyoto (FDSK-11)., Results: Number of teeth was significantly related to chewing ability (P<0.001). The participants with low chewing ability had significantly lower ADL scores in the items of self-maintenance (P=0.029) and intellectual activity (P=0.021). There was a significant association between low chewing ability and depression (P<0.001). Lower cognitive functions were significantly related to low chewing ability; MMSE (P=0.022), HDSR (P=0.017) and FAB (P=0.002). The participants with low chewing ability had lower food variety (P<0.001), and less frequent intake of beans, vegetables, seaweed and nuts, than the participants with high chewing ability., Conclusion: Low chewing ability evaluated by color-changeable gum was associated with lower ADL, lower cognitive functioning, depression and food insufficiency in the community-dwelling elderly. More attention should be paid to assessing chewing ability of elderly persons in community settings., (© 2012 Japan Geriatrics Society.)

Depression screening was conducted to determine the health status of community-dwelling elderly individuals, and the concept of advance care planning was introduced. While depression screening among the elderly often uses the Geriatric Depression Scale, a single question regarding depressive mood also provides a valid measure of depression in elderly persons. Depression is associated with lower activities of daily living, competence, and subjective quality of life among the elderly living in Vietnam and Indonesia, as well as in Japan. Advance care planning is a process of discussion between individuals and their care providers to make decisions about future care preferences and priorities, while they are still capable. If they wish, they may prepare an advance directive to inform others about their decisions and best interests, such as a written advance decision to refuse treatment and/or appointment of a person with lasting powers of attorney. The purpose of advance care planning is to enable elderly persons to receive better end-of-life care. To promote introduction of advance care planning in Japan, voluntary discussion among family members should be encouraged.

The purpose of this study was to examine the prevalence of screening-based depression and the association of depression with activities of daily living (ADL) and quality of life (QOL) of community-dwelling elderly in the developing and developed countries. A total of 2,695 community-dwelling elderly subjects aged 60 years or older living in five rural Asian towns (Indonesia: 411, Vietnam: 379, Japan: 1,905) participated in this cross-sectional study. Depressive symptoms were assessed using a 15-item geriatric depression scale (GDS-15). ADL, higher daily activities, and medical and social history were assessed by interviews or self-report questionnaires. For the assessment of subjective QOL, a 100mm visual analogue scale was used. Using a cut-point of 5/6 for the GDS-15, 782 participants (29.0%) appeared to have depression (Indonesia: 33.8%, Vietnam: 17.2%, Japan: 30.3%). Subjects with depression had significantly lower scores for both ADL and QOL than those without depression in all the three countries. In all the three countries, 17.2-33.8% of community-dwelling elderly subjects had screening-based depression, which was commonly associated with both lower quantitative ADL and lower QOL.

This cross-sectional study examined the prevalence of screening-based depression and compared the scores of activities of daily living (ADL) and quality of life (QOL) between community-dwelling elderly subjects with and without depression in Japan. Elderly subjects aged 65 or older living in four rural towns participated in 2000 or 2001 (n = 5363, female 58.3%, mean (S.D.) age 74.6 (7.0) years). Depressive symptoms were assessed using a 15-item Geriatric Depression Scale (GDS-15) and ADL, higher functions, and medical and social histories were assessed by self-report questionnaires. For assessing subjective QOL, a 100 mm visual analogue scale was used. One thousand seven hundred ninety-eight participants (33.5%, range, 32.3-34.6%) had suggestive depression using cutoff 5/6 of GDS-15. Subjects with depression revealed significantly lower scores for ADL and QOL than those without depression. Prevalence of screening-based depression was similar in the four different rural Japanese towns. However, the reported prevalence of depression varies enormously in different country. Primary physicians and caregivers should pay more attention to depression in the community-dwelling elderly population, especially below the threshold of major depression as minor depression or dysthymia., (Copyright 2003 Elsevier Ireland Ltd.)

Background: Previous studies have reported that self-rated health (SRH) predicts subsequent mortality. However, less is known about the association between SRH and functional ability. The aim of this study was to examine whether SRH predicts decline in basic activities of daily living (ADL), even after adjustment for depression, among community-dwelling older adults in Japan.Methods: A three-year prospective cohort study was conducted among 654 residents aged 65 years and older without disability in performing basic ADL at baseline. SRH was assessed using a visual analogue scale (range; 0-100), and dichotomized into low and high groups. Information on functional ability, sociodemographic factors, depressive symptoms, and medical conditions were obtained using a self-administered questionnaire. Logistic regression analysis was used to examine the association between baseline SRH and functional decline three years later.Results: One hundred and eight (16.5%) participants reported a decline in basic ADL at the three-year follow-up. Multiple logistic regression analysis showed that the low SRH group had a higher risk for functional decline compared to the high SRH group, even after controlling for potential confounding factors (odds ratio (OR) = 2.4; 95% confidence interval (CI) = 1.3-4.4). Furthermore, a 10-point difference in SRH score was associated with subsequent functional decline (OR = 1.37; 95% CI = 1.16-1.61).Conclusions: SRH was an independent predictor of functional decline. SRH could be a simple assessment tool for predicting the loss or maintenance of functional ability in community-dwelling older adults. Positive self-evaluation might be useful to maintain an active lifestyle and stay healthy. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Metabolic syndrome (Met.S) is a risk factor for stroke, dementia, and ischemic heart disease (IHD). It is unclear whether Met.S is an independent risk factor for functional dependence, depression, cognitive impairment, and low health-related quality of life (HRQoL) in a population free of clinical stroke. DESIGN: Cross-sectional. SETTING: Two communities in southern Brazil. PARTICIPANTS: Four hundred twenty people aged 60 and older. MEASUREMENTS: An adapted (body mass index ≥30 kg/m2 and blood pressure ≥140/90) Adult Treatment Panel III definition was used in diagnosing Met.S. Depression ( Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Revised) and Mini-Mental State Examination were evaluated along with activities of daily living (ADLs) and instrumental activities of daily living (IADLs). HRQoL was measured using a visual analogue scale (0–10). All values were adjusted for age, sex, and presence of IHD. RESULTS: Forty (9.5%) subjects had a stroke and were excluded from the final analysis. Met.S was present in 37.4% of the stroke-free population. Met.S was significantly and independently associated with 2.24 times as much ADL dependence, 2.39 times as much IADL dependence, a 2.12 times higher risk of depression, a 2.27 times higher likelihood of cognitive impairment, and a 1.62 times higher chance of low self-perceived HRQoL (all P<0.05). Adjustment for its own components reduced the strength of the above associations but did not eliminate their statistical significance. If Met.S were removed from this population, dependence, depression, cognitive impairment, and low QoL would be reduced 15.0% to 21.4%. CONCLUSION: Met.S was significantly associated with functional dependence, depression, cognitive impairment, and low HRQoL, and its effects were independent of clinical stroke, IHD, and its own individual components.

Background: The Comprehensive Geriatric Assessment (CGA) for inpatients is very useful to improve the outcomes of elderly patients. However, most of the elderly patients are provided their care by general practitioners in primary care settings without comprehensive assessment. Concise and practical assessment is necessary for the detection of geriatric problems and sufficient care in the outpatient clinic. Methods: The CGA was introduced in the outpatient clinic for elderly people in Kyoto University Hospital and 309 patients participated in the study, where cognitive impairment, depressive symptoms, activities of daily living, and self-reported hearing and visual impairment were assessed. Results: In the patients studied, the most prevalent chief complaint was memory loss (19%). Among the patients complaining of memory loss, two-thirds of the patients were diagnosed as cognitively impaired by the Mini-Mental State Examination. Multiple logistic regression analysis showed that hearing and visual impairment was significantly associated with functional disabilities and that hearing impairment was significantly associated with depressive symptoms. Conclusions: Thus, the CGA for outpatients is useful for the detection of functional disabilities and depressive symptoms by asking about their sensory impairment as well as for the detection of cognitive impairment in elderly patients. Therefore, concise and practical assessment should be introduced in the primary care settings to improve the quality of life of elderly people. [ABSTRACT FROM AUTHOR]

Background: To determine the utility of various serum markers for assessment of cognitive and mental functions in the elderly, we performed a Comprehensive Geriatric Assessment (CGA) in the out-patient clinic in Kyoto University Hospital. Methods: We measured serum levels of dehydroepiandrosterone (DHEA), DHEA-S, malondialdehyde low-density lipoproteins (MDA-LDL), and high-sensitivity C-reactive protein (hs-CRP) in 145 patients to find the association of these markers with activities of daily living (ADL), cognitive impairment and depressive symptoms. Results: We found that the levels of hs-CRP were significantly higher in patients with lower scores in Mini-Mental State Examination (MMSE) and Kohs block design test, and higher scores in the button test, indicating that hs-CRP may be associated with the cognitive function in elderly patients. We also found that the levels of DHEA-S were lower in patients with higher scores (9 or over) on the Geriatric Depression Scale-15 (GDS), indicating that DHEA-S may be associated with depressive mode in elderly patients. Total cholesterol, high-density cholesterol (HDL-C), or albumin were not statistically different in each group studied. Conclusions: Thus, our data indicate that measuring hs-CRP and DHEA-S would be helpful to assess the cognitive function and depressive symptoms in elderly patients. [ABSTRACT FROM AUTHOR]

The objective of the present study is to compare the findings of comprehensive geriatric assessment between community-dwelling elderly people in Korea and in Japan. A cross-sectional, interview- and examination-based study was undertaken of community-dwelling elderly people living in a rural district, Hongchon, in Korea and in a rural town, Sonobe, in Kyoto in Japan. Two hundred and thirty-eight community-dwelling elderly people aged 60 years and over in Korea and 411 aged 65 years and over in Kyoto, Japan were examined using a common comprehensive geriatric assessment tool. Interviews concerning activities of daily living (ADL), medical and social history, quality of life (QOL) and the 15-item Geriatric Depression Scale were conducted as well as anthropometric and blood chemical examinations. Findings from the two groups were compared using unpaired T-test andχ2 test. All examined ADLs except for the social ADL were significantly lower in Korean elderly subjects than in Japanese. Only the mean social ADL score of each group showed no difference. The prevalence of depression assessed by the 15-item Geriatric Depression Scale was higher in Korean elderly subjects than in Japanese. Scores for QOL indices were lower in the Korean subjects than in the Japanese. Korean subjects showed higher mean body mass indices, blood sugar concentrations and prevalences of impaired glucose tolerance than Japanese. Mean age, sex ratio and living situation (living alone or not, etc.) were not significantly different between the two groups. Comparative features of comprehensive geriatric assessment of community-dwelling elderly between Korea and Japan were reported. Although both are highly economically developed countries in Asia, it was revealed that elderly Korean subjects were in poorer condition with regard to such ADLs as those relating to basic activities, information, instrumental and intellectual ones, in comparison with Japanese subjects. The one exception was the social ADL. At the same time, Korean subjects showed a higher prevalence of depression and lower scores for QOL. A high prevalence of impaired glucose tolerance in Korea was noteworthy. We assumed psychosocial rather than biological factors had produced such diversities. [ABSTRACT FROM AUTHOR]
