Research on sexual orientation and substance use has established that lesbian, gay, and bisexual (LGB) individuals are more likely to smoke than heterosexuals. This analysis furthers the examination of smoking behaviors across sexual orientation groups by describing how same- and opposite-sex romantic attraction, and changes in romantic attraction, are associated with distinct six-year developmental trajectories of smoking. The National Longitudinal Study of Adolescent Health dataset is used to test our hypotheses. Multinomial logistic regressions predicting smoking trajectory membership as a function of romantic attraction were separately estimated for men and women. Romantic attraction effects were found only for women. The change from self-reported heterosexual attraction to lesbian or bisexual attraction was more predictive of higher smoking trajectories than was a consistent lesbian or bisexual attraction, with potentially important differences between the smoking patterns of these two groups.
性取向和物质使用的研究已经确立，同性恋、双性恋和异性恋（LGB）个体比异性恋者更有可能吸烟。本分析通过描述同性和异性恋吸引力以及浪漫吸引力的变化如何与吸烟的独特六年发展轨迹相关，进一步检查了性取向群体中的吸烟行为。使用国家青少年健康纵向研究数据集来检验我们的假设。对于男性和女性，分别使用多项逻辑回归预测作为浪漫吸引力函数的吸烟轨迹成员资格。仅在女性中发现了浪漫吸引力的影响。从自我报告的异性恋吸引力向同性恋或双性恋吸引力的转变比持续的同性恋或双性恋吸引力更能预测更高的吸烟轨迹，这两个群体的吸烟模式存在潜在的重要差异。
