Approximately 4 million U.S. service members took part in the wars in Afghanistan and Iraq. Shortly after troops started returning from their deployments, some active-duty service members and veterans began experiencing mental health problems. Given the stressors associated with war, it is not surprising that some service members developed such mental health conditions as posttraumatic stress disorder, depression, and substance use disorder. Subsequent epidemiologic studies conducted on military and veteran populations that served in the operations in Afghanistan and Iraq provided scientific evidence that those who fought were in fact being diagnosed with mental illnesses and experiencing mental healthâ€"related outcomesâ€"in particular, suicideâ€"at a higher rate than the general population. This report provides a comprehensive assessment of the quality, capacity, and access to mental health care services for veterans who served in the Armed Forces in Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn. It includes an analysis of not only the quality and capacity of mental health care services within the Department of Veterans Affairs, but also barriers faced by patients in utilizing those services.

This book contains papers presented at a conference which describe studies of a World War II hepatitis epidemic, a genetic analysis of substance use in veteran twins, hemorrhagic fever with renal syndrome, the psychological effects of military captivity, and dioxin in adipose tissue. Other papers discuss radiation risk studies in military populations and resources for epidemiologic research in Vietnam-era veterans. This volume should be of interest to epidemiologists, medical researchers, and others interested in public health.
