Review: Prevalence and Co-Occurrence of Addictions Among Sexual Minority Subgroups

The purpose of this study is to present current data on the prevalence and co-occurrence of 12 substance and behavioral addictions among adult cisgender sexual minorities (SM). We utilized MEDLINE, PsycINFO, and Google Scholar databases to systematically review the literature on alcohol, nicotine, cannabis, illicit drugs, gambling, eating/food, Internet, sex, love, exercise, work, and shopping within the SM community. Peer reviewed empirical articles in English from 2000 to 2019 were included. When possible, we compared prevalence and co-occurrence statistics between four SM subgroups (stratified into lesbian women, bisexual women, gay men, and bisexual men), and used heterosexual women and men as reference groups. Studies were scant within each area of addiction with the most studies focusing on addictions acknowledged within the DSM-V (alcohol, nicotine, cannabis, illicit drugs, gambling). Significantly fewer studies addressed the prevalence and co-occurrence of behavioral addictions across SM subgroups. Most studies assessing addiction among SM populations either categorize SMs into a single group or only stratify by gender. However, even with limited research, the findings from this review suggest that significant differences in addictive behaviors exist when comparing one SM subgroup to another. There is a strong need for more research that quantifies these disparities through prevalence and co-occurrence statistics.
