IntroductionThe purpose of this study is to determine the past-year prevalence estimates of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder based on sexual identity among U.S. adults, and to examine potential variations in these estimates by age, race/ethnicity, and sexual identity-attraction concordance/discordance.MethodsThe 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions collected data via in-person interviews with a cross-sectional nationally representative sample of non-institutionalized adults (response rate=60.1%) and analyses for the present study were conducted in 2017.ResultsAny past-year nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder were most prevalent among sexual minority-identified adults compared with heterosexual-identified adults, with notable variations based on sex, age, race/ethnicity, and sexual identity-attraction discordance. Elevated rates of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder among sexual minorities were most prevalent among younger lesbian women and gay men, and all age groups of bisexual men and women. The odds of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder were significantly greater among sexual identity-attraction discordant women and significantly lower among sexual identity-attraction discordant men.ConclusionsThese findings provide valuable new information about sexual minority subgroups, such as self-identified bisexual older adults and sexual identity-attraction discordant women, that appear to be at higher risk for adverse smoking-related health consequences as a result of their elevated rates of cigarette smoking. Additional attention is warranted to examine these high-risk subpopulations prospectively and, if the results are replicated with larger samples, this information can be used to target smoking-cessation and lung cancer screening efforts.Copyright © 2018 American Journal of Preventive Medicine.
