Demographic, Behavioral, and Proximal Risk Factors for Gambling Disorder in the US Military.

Abstract

To estimate the diagnostic prevalence and incidence of gambling disorder among United States service members and to identify associated risk factors, including demographics, history of mental illness or substance misuse, and proximity to legalized gambling vicinities. Gambling disorder cases comprised active component Service members who received a pathological or problem gambling diagnosis between October 1, 2005 and September 30, 2015. There were 901 cases (392 incidents) during the study period. Controls were matched on the case military entrance date (N = 43,564). Geospatial distance between gambling venue and military treatment facilities were calculated, then multivariable logistic regression and survival analyses were conducted. The 10-year prevalence of gambling disorder was 6.6 per 100,000. Men were 3.5 times more likely than women to receive a gambling disorder diagnosis. Other risk factors included age over 24, Asian or Black race, formerly married, and enlisted rank. The odds of gambling disorder increased with duration and proximity to gambling venues, ranging from 2.0 to 3.9. Service members with prior substance misuse or mental health conditions were 3.9 times and 6.3 times more likely to receive a disordered gambling diagnosis than those without substance misuse or mental illness history, respectively. The results of this study reveal that proximity to gambling venues and slot machines on bases, as well as a history of substance misuse or mental disorders, are important risk factors for gambling disorder in the US military. Department of Defense screening policies that focus on high-risk populations are appropriate. (Am J Addict 2021;00:00-00).
