Research Abstract |
Purpose : To determine the prevalence of major depression and to know the effects of demographic variables and major life events on the disorders among middle-aged and elderly community populations in Japan. Methods : A random sample (n=500) was selected from residents aged 50 + in a rural city of the Gifu Prefecture, Japan. Trained interviewers contacted 372 subjects between February 1996 and July 1997, and conducted 246 (66%) face-to-face interviews. The Japanese translation of the Composite International Diagnostic Interview ver.1.1 (WHO,1993 ; modified by Kessler et al., 1994) was used to assess a lifetime experience of major depression according to DSM-III-R criteria. Selected 28 major life events in the lifetime were also assessed in the interview. Results : Lifetime prevalence rate of major depression was 4.6%. A significantly higher age-specific cumulative rate was observed in a younger birth cohort (p<0.05). Major physical illness and death of child were significantly associated with higher risk of major depression after controlling for sex and birth cohort (hazard ratios, 10.0 and 16.0, respectively). Conclusion : The lifetime prevalence rate of major depression was similar with ones reported in the Western countries. Being in younger birth cohort, physical illnesses and death of child might be risk factors for major depression.
