Key result
Exposure to combat and exposure to death during military service had independent and lasting impacts on the trajectories of psychiatric problems among aging veterans over a 10-year period.
Why the study?
Do service related exposures (combat and exposure to death) worsen trajectories of depressive symptoms and psychiatric problems in aging veterans?

Do service related exposures (combat and exposure to death) worsen trajectories of depressive symptoms and psychiatric problems in aging veterans?
Exposure to death during military service is a robust risk marker for long-term psychiatric problems in aging veterans, independent of combat exposure.

Death exposure flags aging veterans for psychiatric monitoring; leaves open whether targeted interventions alter trajectories.
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 significant and lasting effect on depressive symptoms for veterans in late life but was reduced to nonsignificance when physical health trajectories were included. Combat and exposure to death had independent and robust impacts on psychiatric problems, which were robust in final models. Discussion: SREs presented varied and significant 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.

Ureña et al. (2016) conducted a cohort in Mental health (depressive symptoms and psychiatric problems) (n=1,662). Service-related exposures (combat and exposure to death) vs. Veterans without these exposures was evaluated on Psychiatric problems trajectory (0.15 SD increase at baseline and 0.51 SD growth over time for combat exposure, p=<0.001). Exposure to combat and exposure to death during military service had independent and lasting impacts on the trajectories of psychiatric problems among aging veterans over a 10-year period.
