Background. Although depressive symptoms in older adults are common, their relationship with disability and the influence of disability on the development of depressive symptoms over time is not well understood. This longitudinal study investigates the change trajectories of both depressive symptoms and disability, as well as their associations over time. Methods. Participants included 442 communitydwelling older adults living in Taiwan, aged 65 years or older, who completed six waves of survey interviews. Depression was scored with the Short Psychiatric Evaluation Schedule and disability with the instrumental and physical activities of daily living measure during each consecutive data collection wave. The autoregressive latent trajectory model and parallel latent growth curve modeling were adopted for analysis of the data. Results. The autoregressive latent trajectory model highlights that previous depressive symptoms (and disability) significantly contributed to the advancement of...
Community study of depression in old age in Taiwan
British Journal of Psychiatry, 2001
BackgroundPublished studies of prevalence of depression in old age in Taiwan have yielded equivocal results.AimsTo study the prevalence of depressive disorders among community-dwelling elderly; further, to assess socio-demographic correlates and life events in relation to depression.MethodA randomised sample of 1500 subjects aged 65 and over was selected from three communities. Research psychiatrists conducted all assessments using the Geriatric Mental State Schedule. The diagnosis of depression was made with the GMS–AGECAT (Automated Geriatric Examination for Computerised Assisted Taxonomy); data on life events were collected with the Taiwanese version of the Life Events and Difficulties Schedule.ResultsOne-month prevalence of psychiatric disorders was 37.7%, with 15.3% depressive neurosis and 5.9% major depression. A high risk of depressive disorders was found among widows with a low educational level living in the urban community, and among those with physical illnesses.Conclusio...

Depression and related syndromes are well identified in older adults. Depression has been reported to increase the incidence of a multitude of somatic disorders. In older adults, the severity of depression is associated with higher mortality rates. The aim of the study is to examine whether the effect of depression screening on mortality is different between individuals with different physical health status. In order to meet this aim, we will first reprove the relationship between depression and mortality rate, and then we will set a subgroup analysis by using self-reported health (SRH) status. Our data source, Taiwan Longitudinal Study on Aging (TLSA), is a population-based prospective cohort study that was initiated by the Health Promotion Administration, Ministry of Health and Welfare, Taiwan. The depression risk was evaluated by 10-items Center for Epidemiologic Studies Depression (CES-D-10), we set 3 CES-D-10 cutting points (5, 10, and 12) and cut our subjects into four groups....
The primary aim in this study was to use a joint analysis approach to examine the association between longitudinal change of depressive symptoms and mortality in older Mexican Americans. The joint model was applied to data from the Hispanic Established Population for Epidemiological Study of the Elderly (HEPESE), a seven year longitudinal study of communitydwelling elderly Mexican-Americans. Depressive symptoms were measured by the Center of Epidemiological Studies Depression Scale (CES-D). The trajectories from two stage model and joint model using change in CES-D, modeled by longitudinal linear, and nonlinear curvatures including quadratic and exponential growth curve, were used as predictors to fit the survival curve. The joint analysis indicated that CES-D score at baseline and exponential curve were significant predictive factors of mortality and trajectories of linear and quadratic change in CES-D score were not associated with mortality in older Mexican-Americans.

Trajectory classes of depressive symptoms in a community sample of older adults
Acta Psychiatrica Scandinavica, 2011
Objective-To identify trajectories of depressive symptoms in older community residents. Method-Depressive symptomatology, based on a modified Center for Epidemiological Studies-Depression scale, was obtained at years 0, 3, 6, and 10, in the Duke Established Populations for Epidemiologic Studies of the Elderly (N=4,162). Generalized growth mixture models identified the latent class trajectories present. Baseline demographic, health and social characteristics distinguishing the classes were identified using multinomial logistic regression. Results-Four latent class trajectories were identified. Class 1-stable low depressive symptomatology (76.6% of the sample); class 2-initially low depressive symptomatology, increasing to the subsyndromal level (10.0%); class3-stable high depressive symptomatology (5.4%); class 4-high depressive symptomatology improving over 6 years before reverting somewhat (8.0%). Class 1 was younger, male, with better education, health, and social resources, in contrast to class 3. Class 2 had poorer cognitive functioning and higher death rate. Class 4 had better health and social resources. Conclusion-Reduction in high depressive symptomatology is associated with more education, better health, fewer stressful events, and a larger social network. Increasing depressive symptomatology is accompanied by poorer physical and cognitive health, more stressful life events, and greater risk of death.
Late-life depressive symptoms: Prediction models of change
Journal of Affective Disorders, 2013
Background: Depression is a well-recognised problem in the elderly. The aim of this study was to determine the factors associated with predictors of change in depressive symptoms, both in subjects with and without baseline significant depressive symptoms. Methods: Longitudinal study of community-dwelling elderly people ( 460 years or older), baseline evaluations, and two additional evaluations were reported. Depressive symptoms were measured using a 30-item geriatric depression scale, and a score of 11 was used as cut-off point for significant depressive symptoms in order to stratify the analyses in two groups: with significant depressive symptoms and without significant depressive symptoms. Sociodemographic data, social support, anxiety, cognition, positive affect, control locus, activities of daily living, recent traumatic life events, physical activity, comorbidities, and quality of life were evaluated. Multi-level generalised estimating equation model was used to assess the impact on the trajectory of depressive symptoms. Results: A number of 7882 subjects were assessed, with 29.42% attrition. At baseline assessment, mean age was 70.96 years, 61.15% were women. Trajectories of depressive symptoms had a decreasing trend. Stronger associations in those with significant depressive symptoms, were social support (OR.971, po .001), chronic pain (OR 2.277, p o.001) and higher locus of control (OR.581, po .001). In contrast for those without baseline significant depressive symptoms anxiety and a higher locus of control were the strongest associations. Conclusions: New insights into late-life depression are provided, with special emphasis in differentiated factors influencing the trajectory when stratifying regarding basal status of significant depressive symptoms. Limitations: The study has not included clinical evaluations and nutritional assessments.

Background: Scant research has taken a life-course perspective to explore the longitudinal impact of socioeconomic disadvantage and perceived social support on the psychological well-being of older women. We sought to explore whether socioeconomic disadvantage and perceived social support in mid-life are associated with subsequent depressive symptomatology among older Taiwanese women. Methods: This study was based on data from the Taiwan Longitudinal Study on Aging conducted on a nationally representative sample (n = 1,073) of women aged 50 and above with a 12-year follow up. Mid-life socioeconomic disadvantage was assessed by socioeconomic status (SES) (i.e., educational attainment, major lifetime occupation in adulthood, and employment status) and economic strain. Perceived social support included three dimensions: listening, caring, and sick care. We used the short form of the Center of Epidemiological Studies-Depression (CES-D) scale that measures depressive symptomatology within two domains (negative affect and lack of positive affect). Growth curve models were employed to predict the relationships between mid-life socioeconomic disadvantage, perceived social support, and subsequent depressive trajectories, controlling for aging effects. Results: Multivariate analyses demonstrated older women in a socioeconomic disadvantaged position are more likely to report higher initial levels of depressive symptoms in both domains; lack of formal education did not exacerbate depressive symptoms in the lack of positive affect domain over time. In addition, mid-life perceived positive social support in caring and sick care was associated with lower initial levels of depressive symptoms in both domains. Conclusions: Our results suggest independent effects of mid-life socioeconomic disadvantage and perceived social support on subsequent depressive symptomatology among older Taiwanese women.
