Resumen
Objectives To examine the effect of co-occurring depressive symptoms and functional disability on mortality in older Mexican–American adults with diabetes mellitus.
Design Longitudinal cohort study.
Setting Hispanic Established Populations for the Epidemiological Study of the Elderly (HEPESE) survey conducted in the southwestern United States (Texas, Colorado, Arizona, New Mexico, California).
Participants Community-dwelling Mexican Americans with self-reported diabetes mellitus participating in the HEPESE survey (N = 624).
Measurements Functional disability was assessed using a modified version of the Katz activity of daily living scale. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. Mortality was determined by examining death certificates and reports from relatives. Cox proportional hazards regression analyses were used to examine the hazard of mortality as a function of co-occurring depressive symptoms and functional disability.
Results Over a 9.2-year follow-up, 391 participants died. Co-occurring high depressive symptoms and functional disability increased the risk of mortality (hazard ratio (HR) = 3.02, 95% confidence interval (CI) = 2.11–4.34). Risk was greater in men (HR = 8.11, 95% CI = 4.34–16.31) than women (HR = 2.21, 95% CI = 1.42–3.43).
Conclusion Co-occurring depressive symptoms and functional disability in older Mexican–American adults with diabetes mellitus increases mortality risk, especially in men. These findings have important implications for research, practice, and public health interventions.
