The association between substance use disorders and mortality among a cohort of Veterans with posttraumatic stress disorder: Variation by age cohort and mortality type

Among Veterans with PTSD, the association between SUD and mortality was most pronounced for the youngest age group, which included Iraq/Afghanistan Veterans. For older age groups, which included Vietnam-era Veterans, SUD was a greater predictor of injury-related mortality. The findings could be useful for identifying PTSD patients at excess risk of mortality.
