Co-occurrence of disadvantage conditions in elderly subjects with depressive symptoms

The aim of this survey study is to describe the association of symptomatic depression with the co-occurrence of psycho-social, functional, and somatic disadvantage conditions in 390 over 70 subjects living at home. The most disadvantaged tertile of various conditions (age, social support, cognition, social interactions, self evaluation of health, disability, number of diseases, and somatic symptoms) was associated with greater risk of symptomatic depression. A subset of conditions that might be causally related to depression (age, social support, financial welfare, diseases, and disability) was used to divide subjects into five levels of increasing multiple disadvantage conditions (MDC). Increasing severity of MDC level was associated with greater risk of symptomatic depression even after adjustment for gender and all five conditions used to define MDC levels (odds ratios ranging from 2.7 to 11.3).
