Mental Health, Sexual Orientation, and Perceived Social Network Support in Relation to Hazardous Alcohol Consumption Among Active Duty Military Men

Knowledge surrounding perceived network support and alcohol consumption among active duty U.S. military personnel is limited, particularly among sexual minorities. We sought to determine the correlates of hazardous alcohol consumption and whether perceived network support moderated the relationship between sexual orientation and Alcohol Use Identification Test (AUDIT-C) score. The sample comprised cisgender men currently serving in the U.S. military (N = 292). Participants were recruited through respondent-driven sampling and completed an online survey. Logistic regression analysis evaluated associations between positive AUDIT-C with sociodemographic characteristics (including sexual orientation), military service, mental health, and perceived social network support. Interaction analysis assessed the moderating effect of perceived network support on sexual orientation and AUDIT-C. Among study participants, 52.7% (154/292) had positive AUDIT-C, while 65.4% (191/292) self-identified as heterosexual/straight and 34.6% (101/292) identified as gay or bisexual. In adjusted analysis, positive AUDIT-C was associated with increased post-traumatic stress disorder symptomatology (adjusted odds ratio [adjOR] 1.03; 95% CI [1.00, 1.06]; p =.019) and high perceived network support (adjOR 1.85; 95% CI [1.04, 3.29]; p =.036), while mental health service utilization had reduced odds of positive AUDIT-C (adjOR 0.40; 95% CI [0.20, 0.78]; p =.007). In interaction analysis, high perceived network support was associated with increased odds of positive AUDIT-C among sexual minority men (adjOR 3.09; 95% CI [1.21, 7.93]; p =.019) but not heterosexual men (adjOR 1.38; 95% CI [0.68, 2.81]; p =.37). Hazardous alcohol use was prevalent among all men in our sample. Perceived social network support may influence hazardous alcohol consumption, particularly among sexual minority servicemen. These findings suggest the potential role of tailored social network-based interventions to decrease hazardous alcohol use among military personnel.
