The Impacts of Service Related Exposures on Trajectories of Mental Health among Aging Veterans

Abstract

Objectives: Drawing on life-course perspective and cumulative advantage theory, we examined whether service related exposures (SREs)-combat and exposure to death have lasting impacts on depressive symptom and psychiatric problem trajectories of aging veterans. Methods: The Health and Retirement Study and linked 2013 Veterans Mail Survey were used to examine SREs and mental health among older veterans between 2002 and 2012 (N = 1,662). Latent growth curves were used to measure how individuals vary from average mental health trajectories based on SREs and other important covariates. Results: Exposure to death had a signifcant and lasting effect on depressive symptoms for veterans in late life but was reduced to nonsignifcance when physical health trajectories were included. Combat and exposure to death had independent and robust impacts on psychiatric problems, which were robust in fnal models. Discussion: SREs presented varied and signifcant impacts, suggesting that combat does not work alone in driving poor mental health trajectories, and that exposure to death is a more robust risk marker for later outcomes.
