Depressive symptom severity is a major risk factor for frailty in community-dwelling older adults with depression. A prospective study.

BACKGROUND: Depression and frailty are closely related, but the mechanisms by which depressed older adults are at an increased risk of becoming frail are still not well understood. AIM: To assess socioeconomic and depression-related risk factors for frailty in older adults with depression. METHODS: Observational and prospective cohort study, with 12-month follow-up, of nonfrail community-dwelling subjects aged ≥70 years old with depression. The main study factors were clinical characteristics of depression, including symptom severity (Hamilton Depression Rating Scale), accompanying anxiety and cognitive symptoms, pharmacological treatment, and social factors including educational level, income, housing conditions and living circumstances, and social network. Frailty status was established according to Fried criteria. RESULTS: We recruited and analysed 216 subjects (mean age 76.5 years; 74% women), 65 (30%) of whom were lost to follow-up. Annual incidence of frailty was 23.2 new cases/100 persons. Age, female gender, osteoarthritis, pain, number of medications, major depression, first-degree family history of depression, depressive symptom severity, low educational level, and low-income level were risk factors for frailty. The multivariate analysis showed that age (odds ratio [OR] = 1.16; 95% confidence interval [CI]: 1.04-1.29), visual analogue scale (VAS)-pain (OR = 1.25; 95% CI: 1.01-1.55), and severe or very severe depressive symptoms (OR = 37.36; 95% CI: 2.68-518.53) were significantly associated with incident frailty at 12 months of follow-up. CONCLUSIONS: Both clinical and social characteristics are risk factors for frailty, but severity of depressive symptoms had the highest independent effect on frailty in depressed aged subjects. Frailty requires a multidisciplinary approach that pays special attention to pain and depressed mood.

Psychosocial factors associated with frailty in the community-dwelling aged population with depression. A cross-sectional study.

OBJECTIVE: There is a two-way relationship between frailty and depression, but the mechanisms by which one may influence the other are not well understood. The objective of this study was to evaluate the relationship between psychosocial factors and frailty in community-dwelling aged populations with depression. DESIGN: Observational cross-sectional study. SITE: 5 primary care centres. PARTICIPANTS: Community-dwelling subjects with depression aged ≥70 years. MAIN MEASUREMENTS: Frailty status was established according to Fried criteria, depression and depression severity were evaluated by DSM-IV criteria and the Hamilton Depression Rating Scale, respectively, and psychosocial factors were assessed using the Gijón Social-Familial Evaluation Scale and ad hoc questionnaires. RESULTS: Recruited were 338 subjects (mean age 77.2 years), 82% women and 36.1% rated as frail. A dose-response relationship was observed between depression severity and frailty risk. Widowhood was a risk factor for frailty, while a higher educational level, home internet, stairs in the home, and an active social life had a protective effect. A multivariate analysis showed that age, number of drugs, and depression severity were independent risk factors for frailty, while an active social life was a protective factor. The severity of depressive symptoms showed higher association with frailty than other clinical and socio-demographic characteristics. CONCLUSIONS: In depressed elderly subjects, frailty is associated with psychologiocal factors such as the intensity of depressive symptoms and with social factors such as education level, widowhood, loneliness, and limited social life. More research is required to better understand the modifiable psychological risk factors for frailty.
