This article reviewed all available research about gambling problems among active duty military personnel. The researchers found a total of 11 relevant sources. All studies were from the U.S. Results revealed that while gambling is a popular pastime among the military personnel, there may be high prevalence of gambling disorders among them. Unfortunately, the military culture may act as a barrier to seeking help for gambling problems. As a result, many personnel may conceal their issues and not seek treatment. The review also showed that people most at risk for gambling problems include males, minority groups, and younger age groups. Finally, gambling disorders often co-occur with other issues, such as depression, substance use problems, suicidal ideas and attempts, and other risky health behaviours. No study had directly examined the association of gambling with post-traumatic stress disorder among active duty military personnel.
