Prevalence of a positive screen for PTSD among OEF/OIF and OEF/OIF-era veterans in a large population-based cohort.

Multiple studies have reported the prevalence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans; however, these studies have been limited to populations who use the Department of Veterans Affairs (VA) for health care, specialty clinic populations, or veterans who deployed. The 3 aims of this study were to report weighted prevalence estimates of a positive screen for PTSD among OEF/OIF and nondeployed veterans, demographic subgroups, and VA health care system users and nonusers. The study analyzed data from the National Health Study for a New Generation of U.S. Veterans, a large population-based cohort of OEF/OIF and OEF/OIF-era veterans. The overall weighted prevalence of a positive screen for PTSD in the study population was 13.5%: 15.8% among OEF/OIF veterans and 10.9% in nondeployed veterans. Among OEF/OIF veterans, there was increased risk of a positive screen for PTSD among VA health care users (OR = 2.71), African Americans (OR = 1.61), those who served in the Army (OR = 2.67), and those on active duty (OR = 1.69). The same trend with decreased magnitude was observed in nondeployed veterans. PTSD is a significant public health problem in OEF/OIF-era veterans, and should not be considered an outcome solely related to deployment.
