[BDSP. Notice produite par INIST-CNRS 8R0xomnC. Diffusion soumise à autorisation]. Objective. We investigated relations between deployment and new-onset depression among US service members recently deployed to the wars in Iraq and Afghanistan. Methods. We included 40219 Millennium Cohort Study participants who completed baseline and follow-up questionnaires and met inclusion criteria. Participants were identified with depression if they met the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire criteria for depression at follow-up, but not at baseline. Results. Deployed men and women with combat exposures had the highest onset of depression, followed by those not deployed and those deployed without combat exposures. Combat-deployed men and women were at increased risk for new-onset depression compared with nondeployed men and women (men : adjusted odds ratio [AOR]=1.32 ; 95% confidence interval [CI]=1.13,1.54 ; women : AOR=2.13 ; 95% CI=1.70,2.65). Conversely, deployment without combat exposures led to decreased risk for new-onset depression compared with those who did not deploy (men : AOR=0.66 ; 95% CI=0.53,0.83 ; women : AOR=0.65 ; 95% CI=0.47,0.89). Conclusions. Deployment with combat exposures is a risk factor for new-onset depression among US service members. Post-deployment screening may be beneficial for US service members exposed to combat.
