Objectives. We examined gender differences in sociodemographic, military service, and mental health characteristics among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans. We evaluated associations between these sociodemographic and service characteristics and depression and posttraumatic stress disorder (PTSD) diagnoses. Methods. In a retrospective, cross-sectional study, we used univariate descriptive statistics and log binominal regression analyses of Department of Veterans Affairs (VA) administrative data on 329 049 OEF and OIF veterans seeking VA health care from April 1, 2002, through March 31, 2008. Results. Female veterans were younger and more likely to be Black and to receive depression diagnoses than were male veterans, who were more frequently diagnosed with PTSD and alcohol use disorders. Older age was associated with a higher prevalence of PTSD and depression diagnoses among women but not among men. Conclusions. Consideration of gender differences among OEF and OIF veterans seeking health care at the VA will facilitate more targeted prevention and treatment services for these newly returning veterans.

This study examined the relationship between routine work environment stress and posttraumatic stress disorder (PTSD) symptoms in a sample of police officers (N = 180) who were first assessed during academy training and reassessed 1-year later. In a model that included gender, ethnicity, traumatic exposure prior to entering the academy, current negative life events, and critical incident exposure over the last year, routine work environment stress was most strongly associated with PTSD symptoms. We also found that routine work environment stress mediated the relationship between critical incident exposure and PTSD symptoms and between current negative life events and PTSD symptoms. Ensuring that the work environment is functioning optimally protects against the effects of duty-related critical incidents and negative life events outside police service.
