A comparison of abstinence outcomes among gay/bisexual and heterosexual male smokers in an intensive, non-tailored smoking cessation study

Abstract

Introduction: Smoking rates are higher among lesbian/gay/bisexual (LGB) than heterosexual (HT) individuals. However, there is scant information regarding smoking cessation treatments and outcomes in LGB populations. This study examined abstinence outcome in response to a high intensity smoking cessation program not specifically tailored to LGB smokers.

Methods: A total of 54 gay/bisexual (GB) and 243 HT male smokers received 8-week open treatment with nicotine patch, bupropion, and counseling. Participants reported biologically verified abstinence at multiple time points during the study.

Results: Demographic, smoking, and psychological characteristics at baseline were similar according to sexual orientation. During the first 2 weeks after quit day, abstinence rates were higher among GB smokers (Week 1: GB = 89%, HT = 82%; Week 2: GB = 77%, HT = 68%; ps < .05); abstinence rates converged subsequently, becoming nearly identical at the end of treatment (Week 8, GB = 59% vs. HT = 57%). In mixed effects longitudinal analysis of end-of-treatment outcome, sexual orientation (b = 1.40, SEM = 0.73, p = .056) and the Sexual Orientation x Time interaction (b = -0.146; SEM = 0.08, p = .058) approached statistical significance, reflecting the higher initial abstinence rates among GB smokers and the later convergence in abstinence rates by sexual orientation.

Discussion: This first report comparing smoking cessation treatment response by sexual orientation found higher initial and similar end-of-treatment abstinence rates in GB and HT smokers. Further work is needed to determine whether these observations from GB smokers who displayed a willingness to attend a non-tailored program and broad similarity with their HT counterparts in many baseline characteristics will replicate in other groups of GB smokers.
