Cigarette Smoking and the Role of Menthol in Tobacco Use Inequalities for Sexual Minorities.

Abstract

Cigarette smoking is disproportionately common among sexual minorities. While menthol market share has increased in the past decade, research on menthol cigarette smoking among sexual minorities is scant. For this study, we examined menthol cigarette smoking in the United States, by sex and sexual identity using a nationally representative sample of adults. We pooled data from the 2015-2019 National Survey on Drug Use and Health. We used chi-square tests and multivariable logistic regression models to examine (1) past 30-day cigarette use, (2) past 30-day menthol use, and (3) menthol preference among adults who have smoked cigarettes in the past 30 days for the following groups: heterosexual/straight males, heterosexual/straight females, gay males, gay/lesbian females, bisexual males, and bisexual females. Data were analyzed in September 2020. Bivariate analyses revealed that prevalence of cigarette smoking and menthol cigarette smoking were higher among sexual minorities compared with heterosexual respondents, and that preference for menthol was highest among lesbian/gay and bisexual females who smoke. Multivariable models showed that compared with heterosexual females who smoke, odds of menthol preference were lower among heterosexual/straight and bisexual males who smoke, and higher among bisexual females. Our study found that menthol preference was disproportionately high among sexual minorities who smoke-bisexual and gay/lesbian females who smoke in particular. Research is needed to understand why menthol use is common among sexual minorities who smoke. Using data from a nationally representative study, this study makes a unique contribution to literature by identifying differences in menthol smoking between sexual minority subgroups. Specifically, we found that menthol smoking was highest among sexual minority females (ie, lesbian/gay and bisexual females) compared with other sexual minorities. These findings highlight the need for targeted interventions to prevent menthol cigarette initiation among sexual minorities, as well as to promote smoking cessation among sexual minorities who smoke menthol cigarettes, with an emphasis on sexual minority females. Future research should examine the impact of a potential menthol ban on these inequalities.
