[BDSP. Notice produite par INIST-CNRS R0xEIHDC. Diffusion soumise à autorisation]. Objective. We investigated the association of the length of time spent at home between deployments, or dwell time, with posttraumatic stress disorder (PTSD) and other mental health disorders. Methods. We included US Marine Corps personnel identified from military deployment records who deployed to Operation Iraqi Freedom once (n =49328) or twice (n =16376). New-onset mental health diagnoses from military medical databases were included. We calculated the ratio of dwell-to-deployment time (DDR) as the length of time between deployments divided by the length of the first deployment. Results. Marines with 2 deployments had higher rates of PTSD than did those with 1 deployment (2.1 % versus 1.2 % ; P <. a ddr representing longer dwell times at home relative to first deployment length was associated with reduced odds of ptsd ratio confidence interval other mental health disorder ci="0.33,0.94)," and disorders conclusions. may reduce postdeployment risk disorders. future research should focus on the role time in adverse outcomes.>
