Background: The objectives of this study were to: (1) estimate the prevalence of family history of alcohol and other drug (AOD) misuse (positive family history [FH+]) in first- and second-degree relatives across sexual identity subgroups (i.e., lesbian, gay, bisexual, heterosexual); (2) compare AOD misuse among offspring of sexual minority and heterosexual parents; and (3) examine the relationships between FH+ and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alcohol use disorder (AUD) and other drug use disorder (ODUD) across sexual identity subgroups. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III (n = 36,309 non-institutionalized U.S. adults aged ≥ 18 years). Data collection occurred in households using structured diagnostic face-to-face interviews during 2012-2013. Results: The presence of FH+ in first- and second-degree relatives was most prevalent among bisexual women relative to all other sexual orientation subgroups. Multivariable regression analyses indicated that the odds of AUD and ODUD were higher among FH+ adults relative to negative family history (FH-) adults. Lesbian and bisexual women had higher odds of AUD compared to heterosexual women, controlling for any FH+; this sexual identity difference was not found for men. There were no significant differences in ODUD between heterosexual FH- men and gay FH- men. We found differences in AOD misuse among offspring of bisexual parents, but not gay or lesbian parents compared to heterosexual parents. Conclusions: Health professionals should consider the higher likelihood of a family history of AOD misuse among sexual minorities, especially bisexual women, when treating these individuals. The lack of differences in AOD misuse among offspring of gay or lesbian parents relative to heterosexual parents warrants attention for legal, policy, and clinical decisions.
