OBJECTIVES
We examined interrelationships among the 3 dimensions of sexual orientation-self-identity, sexual attraction, and sexual experience-and their associations with substance use among adolescents and young adults.
METHODS
To estimate total and net associations of sexual identity, attraction, and experience with use of tobacco, drugs, and alcohol, we applied logistic regression to cross-sectional data from the National Survey of Family Growth Cycle 6.
RESULTS
We found a lack of concordance among the different dimensions of sexual orientation. More youths reported same-gender sexual attraction and same-gender sexual experiences than identified as lesbian, gay, or bisexual. Estimates of substance use prevalence differed significantly by gender and across dimensions of sexual orientation. Sexual experience was the most consistent predictor of substance use. Women and men with no sexual experience had the lowest odds of all forms of substance use; those reporting sexual experience with partners of both genders had the highest odds.
CONCLUSIONS
Our findings indicate that sexual identity was less strongly associated with substance use than sexual experience and attraction were, pointing to the need for more nuanced indicators of sexual orientation in public health studies.
目的
我们研究了性取向的三个维度——自我认同、性吸引和性经历——之间的相互关系，以及它们与青少年和年轻人物质使用的关联。
方法
为了估计性认同、性吸引和性经历与吸烟、使用毒品和饮酒之间的总关联和净关联，我们对国家家庭增长周期 6 号调查的横断面数据应用了逻辑回归分析。
结果
我们发现性取向的不同维度之间存在不一致性。报告同性性吸引和同性性经历的年轻人多于自认为是女同性恋、男同性恋或双性恋的年轻人。物质使用的流行率估计值因性别和性取向的不同维度而有显著差异。性经历是物质使用的最一致预测因素。没有性经历的女性和男性使用所有形式物质的几率最低；与两性伴侣发生过性经历的人几率最高。
结论
我们的研究结果表明，性认同与物质使用的关联不如性经历和性吸引强，这表明在公共卫生研究中需要更细致的性取向指标。
