少数性取向（即男同性恋、女同性恋、双性恋和大多数异性恋）的青少年吸烟的风险很高。我们研究了青春期和成年初期吸烟的性取向差异，并调查了首次吸烟的年龄对吸烟差异的影响。我们使用了“今日成长研究”的数据，该研究对 12 至 24 岁的青少年进行了大型纵向队列跟踪（N = 13,913）。每年或每两年填写一次自我管理的调查问卷，评估首次吸烟的年龄、当前吸烟情况、吸烟频率、每天吸烟的数量和尼古丁依赖。比例风险生存分析和重复测量回归估计了吸烟的性取向差异。与完全异性恋者相比，女同性恋/男同性恋、双性恋和大多数异性恋青少年吸第一支烟的年龄更小，更有可能是当前吸烟者，并且吸烟频率更高。在过去一年的吸烟者中，与完全异性恋的女性相比，性少数女性每天吸烟更多，尼古丁依赖得分更高。在某些情况下，性别和年龄改变了性取向和吸烟之间的关系，女性性少数群体和年轻时期的性少数群体的相对风险更大。大多数异性恋者和双性恋者的吸烟年龄较年轻，导致女同性恋者吸烟率上升，但男同性恋者则不然。与异性恋者相比，性取向少数群体在青春期和成年初期吸烟的风险更大。女性的差异更大，并且在青春期早期很明显。预防和戒烟工作应针对这一人群，最好从青春期早期开始。
Youths with a minority sexual orientation (i.e., gay, lesbian, bisexual, and mostly heterosexual) are at high risk for cigarette smoking. We examined sexual-orientation disparities in smoking during adolescence and emerging adulthood and investigated the role of age at first smoking in contributing to smoking disparities.We used data from the Growing Up Today Study, a large longitudinal cohort of adolescents followed from ages 12 to 24 years (N = 13,913). Self-administered questionnaires filled out annually or biennially assessed age at first smoking, current smoking, frequency of smoking, number of cigarettes smoked daily, and nicotine dependence. Proportional hazards survival analysis and repeated measures regression estimated sexual-orientation differences in smoking.Compared with completely heterosexuals, lesbian/gay, bisexual, and mostly heterosexual youths smoked their first cigarette at younger ages, were more likely to be current smokers, and had higher frequency of smoking. Among past-year smokers, sexual-minority females smoked more cigarettes daily and scored higher on nicotine dependence than completely heterosexual females. In some instances, gender and age modified relationships between sexual orientation and smoking, with relative risk accentuated in female sexual minorities and in sexual minorities during younger ages. Younger age of smoking onset contributed to elevated smoking in mostly heterosexuals and bisexuals, and to a lesser extent in lesbians, but not in gay males.Sexual-orientation minorities are at greater risk for smoking during adolescence and emerging adulthood than heterosexuals. Disparities are larger in females and evident in early adolescence. Prevention and cessation efforts should target this population, preferably beginning in early adolescence.
