The U.S. military is frequently called upon as the first line of response or defense in conflicts and disasters, often resulting in service members' separation from family or home life for extended periods of time. Reports have suggested that personnel involved in combat operations or peacekeeping missions following combat may have increased symptoms of psychological distress, with one report recently suggesting significant risk of mental health problems after combat duty in Iraq and Afghanistan. The mental health of military service members affects organizational productivity and effectiveness and is of great importance to the U.S. military for retention, readiness, and mission capability. In this report, the authors describe the baseline prevalence of mental disorders in a large U.S. military cohort, the Millennium Cohort, that will be longitudinally followed until 2022. Using crude and weighted prevalence and multivariable logistic regression, the mental health morbidity of the Millennium Cohort is reported for a variety of demographic characteristics. The findings suggest a mentally healthier population than other comparison populations. However, the higher prevalence of alcohol abuse and the disproportionately higher burden of mental disorders among some subgroups -- members who are female, younger, less educated, single, White (non-Hispanic), short-term service, enlisted, and Army - - should prompt further clinical investigation and intervention. Further coordination between primary care providers, mental health specialists, and researchers is necessary to identify and prioritize critical areas for research and improvement of clinical services to protect the mental health of the U.S. military. 收起
