具有少数性取向的青少年（例如，女同性恋、男同性恋、双性恋）比异性恋同龄人更有可能使用药物。这项研究旨在通过以下方式增进对这一弱势群体吸毒情况的了解：1）比较过去一年非法药物使用的纵向模式（例如，大麻，可卡因，摇头丸）和滥用处方药的少数性取向青年相对于异性恋青年，2）研究性取向亚组，性别和年龄与药物使用风险的变化。数据来自“今日成长研究”（Growing Up Today Study），这是一项以社区为基础的青少年队列研究，在1999年至2005年期间，对12至23岁的青少年进行了三次自我问卷调查（N= 12，644;占原始队列的74.9%）。采用多变量重复测量广义估计方程，采用改良Poisson回归估计相对危险度。表明他们的性取向主要是异性恋，双性恋或女同性恋/男同性恋的参与者比完全异性恋的年轻人更有可能报告过去一年的非法药物使用和滥用处方药。性别是一个重要的修正因素;双性恋女性最有可能报告吸毒。年龄也是风险的一个重要修正因素;青少年期（12-17岁）的少数性取向青年和异性恋青年之间的吸毒差异大于初成年期（18-23岁）。研究必须侧重于查明少数性取向青年吸毒风险过高的原因。这些信息对于制定减少这一人群吸毒所急需的干预措施至关重要。需要及早开始努力，因为吸毒方面的性取向差异在青少年时期就很明显。
Adolescents with a minority sexual orientation (e.g., lesbian, gay, bisexual) are more likely to use substances than their heterosexual peers. This study aimed to increase understanding of the development of drug use in this vulnerable population by: 1) comparing longitudinal patterns of past-year illicit drug use (e.g., marijuana, cocaine, ecstasy) and misuse of prescription drugs among minority sexual orientation youth relative to heterosexual youth and, 2) examining how sexual orientation subgroup, gender, and age relate to variation in risk of drug use. Data come from the Growing Up Today Study, a community-based cohort of adolescents who were assessed three times between 1999–2005 with self-administered questionnaires when they ranged in age from 12 to 23 years (N=12,644; 74.9% of the original cohort). Multivariable repeated measures generalized estimating equations using modified Poisson regression was used to estimate relative risks. Participants indicating their sexual orientation was mostly heterosexual, bisexual, or lesbian/gay were more likely than completely heterosexual youth to report past-year illicit drug use and misuse of prescription drugs. Gender was an important modifier; bisexual females were most likely to report drug use. Age was also an important modifier of risk; differences in drug use between minority sexual orientation and heterosexual youth were larger during adolescence (12–17 years) than during emerging adulthood (18–23 years). Research must focus on identifying reasons why minority sexual orientation youth are at disproportionate risk for drug use. Such information is essential for developing interventions that are critically needed to reduce drug use in this population. Efforts need to begin early because large sexual orientation disparities in drug use are evident by adolescence.
