Sexual minorities and substance use treatment utilization: New evidence from a national sample.

introductionMinority stress theory suggests that sexual minorities would be, on average, less likely than heterosexual individuals to seek out substance use treatment (due to concerns of stigma and rejection). However, prior research on the subject is mixed, and largely dated. In light of historic increases in societal acceptance and legal protections for sexual minorities, the field needs an up-to-date assessment of treatment utilization among this population.

methodsThis study used data from the 2015-2019 National Survey on Drug Use and Health to examine the association between key independent variables (sexual identity, gender) and substance use treatment utilization using binary logistic regression. We conducted analyses using a sample of adults with a past-year substance use disorder (N = 21,926).

resultsControlling for demographic factors, with heterosexual individuals as the comparison group, gay/lesbian individuals (AOR = 2.12, CI = 1.19-3.77) were significantly more likely and bisexual individuals (AOR = 0.49, CI = 0.24-1.00) significantly less likely to report treatment utilization. Bisexual individuals were also less likely than gay/lesbian individuals to report treatment utilization (AOR = 0.10, CI = 0.05-0.23). Interaction tests examining sexual orientation and gender showed no difference in treatment utilization between gay men and lesbian women, and revealed that bisexual identity was associated with decreased likelihood of treatment utilization for men (p = .004) but not for women.

conclusionSexual orientation, particularly in the context of social identity, plays a significant role in substance use treatment utilization. Bisexual men face unique barriers to treatment, which is concerning given the high rates of substance use among this and other sexual minority populations.
