Sexual minority (i.e., lesbian, gay, and bisexual) adults smoke cigarettes at higher rates than heterosexual adults. Smoking after receiving a cancer diagnosis is a major health concern, yet risk of continued smoking among sexual minority cancer survivors is as yet unknown. The current study examines current smoking among sexual minority vs. heterosexual adult cancer survivors.
Data drawn from the 2010 Behavioral Risk Factor Surveillance System survey in five states (Alaska, California, Massachusetts, New Mexico, and Wisconsin) included items about sexual orientation, cancer diagnosis, and tobacco use. The analytic sample included 124 sexual minority and 248 propensity score matched heterosexual adult cancer survivors.
Bivariate analysis showed that sexual minority cancer survivors had twice the odds of current smoking as their heterosexual counterparts (OR=2.03, 95%CI:1.09-3.80). In exploratory analyses stratified by sex, sexual minority disparities in prevalence of smoking post-cancer showed a trend toward significance among females, not males.
The current study offers preliminary evidence that sexual minority status is one variable among many that must be taken into account when assessing health behaviors post-cancer diagnosis. Future research should identify mechanisms leading from sexual minority status to increased rates of smoking and develop tailored smoking cessation interventions.
性少数群体（即女同性恋、男同性恋和双性恋）成年人吸烟率高于异性恋成年人。癌症诊断后仍继续吸烟是一个主要的健康问题，但性少数群体癌症幸存者持续吸烟的风险尚不清楚。本研究调查性少数群体与异性恋成年癌症幸存者的当前吸烟情况。
从阿拉斯加、加利福尼亚、马萨诸塞、新墨西哥和威斯康星五个州的2010年行为危险因素监测系统调查中获取的数据，包括有关性取向、癌症诊断和烟草使用的项目。分析样本包括124名性少数群体和248名倾向得分匹配的异性恋成年癌症幸存者。
双变量分析显示，性少数群体癌症幸存者当前吸烟的几率是异性恋幸存者的两倍（OR=2.03，95%CI：1.09-3.80）。在按性别分层的探索性分析中，癌症后吸烟患病率的性少数群体差异在女性中显示出显著趋势，在男性中则不然。
本研究提供了初步证据，表明性少数群体身份是癌症诊断后评估健康行为时必须考虑的众多变量之一。未来的研究应确定导致性少数群体身份导致吸烟率增加的机制，并制定针对性的戒烟干预措施。
