The effect of depression on the association between military service and life satisfaction.

Purpose: The purpose of this study was to examine the effect of depression on the association between a history of military service and life satisfaction among a nationally representative sample of US men.

Methods: Data from 57,905 men were obtained from the 2006 Behavioral Risk Factor Surveillance survey that assessed depression, history of military service, and life satisfaction. Multivariable logistic regression was conducted, controlling for demographics and physical health characteristics.

Results: In non-depressed men, a history of military service was associated with higher odds of life satisfaction, OR (95% CI) = 1.39 (1.07, 1.81). However, the interaction between depression and a history of military service was significant, OR (95% CI) = 0.56 (0.38–0.84), such that a history of military service was associated with equivalent odds of satisfaction in depressed men, OR (95% CI) = 0.78 (0.56–1.09).

Conclusions: Intervention efforts targeting depression in men with a history of military service may have a significant impact on their well-being. Future research should replicate these findings, examine potential mechanisms of the effects, and study the utility of life satisfaction measures in this population.
