AIM: In our aging society, the number of community-dwelling dependent elderly people is increasing. Many studies have shown that depression influences the health of older persons. In the present study, we examined whether depressive status is associated with mortality and hospitalization in community-dwelling dependent older people during a 3-year follow-up period. METHODS: This study was a prospective cohort analysis of 1,409 community-dwelling disabled elderly (489 men, 920 women; average age 80.1, the Nagoya Longitudinal Study for Frail Elderly). Data included demographic characteristics, basic activities of daily living (ADL) scores, comorbidity, and depressive status as assessed by the short version of the Geriatric Depression Scale (GDS-15) at baseline. The participants were considered to have depression or severe depression if their GDS-15 score was 6-10 or above 10, respectively. The Cox proportional hazard model and the Kaplan-Meier method were used to assess any association with depressive status at baseline with mortality or hospitalization during a 3-year period. RESULTS: During a 3-year observation, 284 participants died (53 at home, 231 at hospital), and 576 were admitted to hospitals. Univariate analysis revealed that the depressive status of participants was associated with mortality and hospitalization during a 3-year follow up. However, multivariate models used to adjust for potential confounders including gender, age, ADL status, and comorbidity, did not show any association between depressive status and mortality and hospitalization. CONCLUSIONS: Depressive status among community-dwelling disabled elderly was not associated with mortality or hospitalization in the present series.
