We examined sexual orientation status differences in alcohol use among youths aged 13 to 18 years or older, and whether differences were moderated by sex, age, or race/ethnicity.
We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys and conducted weighted analyses, adjusting for complex design effects. We operationalized sexual orientation status with items assessing sexual orientation identity, sexual behavior, sexual attraction, or combinations of these.
Compared with exclusively heterosexual youths, sexual-minority youths were more likely to report each of the primary study outcomes (i.e., lifetime and past-month alcohol use, past-month heavy episodic drinking, earlier onset of drinking, and more frequent past-month drinking). Alcohol-use disparities were larger and more robust for (1) bisexual youths than lesbian or gay youths, (2) girls than boys, and (3) younger than older youths. Few differences in outcomes were moderated by race/ethnicity.
Bisexual youths, sexual-minority girls, and younger sexual-minority youths showed the largest alcohol-use disparities. Research is needed that focuses on identifying explanatory or mediating mechanisms, psychiatric or mental health comorbidities, and long-term consequences of early onset alcohol use, particularly frequent or heavy use, among sexual-minority youths.
我们研究了 13 至 18 岁或以上青少年的饮酒行为在性取向方面的差异，以及这些差异是否受到性别、年龄或种族/民族的调节。
我们汇总了 2005 年和 2007 年青少年风险行为调查的数据，并进行了加权分析，对复杂的设计效果进行了调整。我们通过评估性取向认同、性行为、性吸引或这些因素的组合来确定性取向状况。
与完全异性恋的青少年相比，性少数群体的青少年更有可能报告所有主要的研究结果（即终生和过去一个月的饮酒、过去一个月的重度饮酒、饮酒开始年龄较早和过去一个月更频繁的饮酒）。在（1）双性恋青少年比女同性恋或男同性恋青少年、（2）女孩比男孩、（3）年轻青少年比年长青少年中，饮酒差异更大且更显著。种族/民族对结果的调节作用很小。
双性恋青少年、性少数群体中的女孩以及年龄较小的性少数群体青少年表现出最大的饮酒差异。需要开展研究，重点关注识别解释或中介机制、精神疾病或心理健康共病以及早期饮酒，特别是频繁或重度饮酒，对性少数群体青少年的长期后果。
