The association between depression and mortality in older community-dwelling populations is still unresolved.
This study determined the effect of both minor and major depression on mortality and examined the role of confounding and explanatory variables on this relationship.
A cohort of 3056 men and women from the Netherlands aged 55 to 85 years were followed up for 4 years.
Major depression was defined according to DSM-III criteria by means of the Diagnostic Interview Schedule.
Minor depression was defined as clinically relevant depression (defined by a Center for Epidemiologic Studies Depression score >= 16) not fulfilling diagnostic criteria for major depression.
After adjustment for confounding variables (sociodemographics, health status), men with minor depression had a 1.80-fold higher risk of death (95% confidence interval, 1.35-2.39) during follow-up than nondepressed men.
In women, minor depression did not significantly increase the mortality risk.
Irrespective of sex, major depression was associated with a 1.83-fold higher mortality risk (95% confidence interval, 1.09-3.10) after adjustment for sociodemographics and health status.
Health behaviors such as smoking and physical inactivity explained only a small part of the excess mortality risk associated with depression. (...)
