目的：与异性恋成年人相比，女同性恋者、男同性恋者和双性恋者(LGB)的物质使用率(SU)更高，但这些差异在不同年龄组之间的差异程度尚不清楚。利用全国调查数据，我们测试了LGB成年人的年龄组寿命差异和最近的SU差异。方法：利用2015年和2016年全国药物使用与健康调查(NSDUH)的67,354名成年人(包括4868名LGB成年人)的数据，我们检查了LGB在终身和最近使用香烟、大麻和非法药物方面的差异。分析按年龄组(18-25岁、26-34岁和35-49岁)分层，并分别将女同性恋者/男同性恋者(L/G)和双性恋成年人与相同性别和年龄组的异性恋成年人进行比较。结果：在L/G人群中，最年轻年龄组的差异(相对于同龄异性恋女性)在多项生活指标和近期SU上显著大于高龄组。相反，在双性恋男性和双性恋女性中，最年轻的年龄组与最年长的年龄组相比，多发性SU差异(相对于相同年龄和性别的异性恋成年人)明显较小。结论：与最近几代LGB个体中少数民族压力减少的假设相反，我们发现SU差异在年轻年龄组中并没有系统性地缩小。相反，不同年龄段的差异呈现出明显的趋势。由于NSDUH数据是横截面的，按年龄组划分的差异可能既反映了年龄变化的发展因素的影响，也反映了时间变化的社会和背景因素的影响。
Purpose: Lesbian, gay, and bisexual (LGB) adults have elevated rates of substance use (SU) relative to heterosexual adults, yet the extent to which these disparities vary across age groups is unknown. Using national survey data, we test for age group differences in lifetime and recent SU disparities among LGB adults. Methods: Using data on 67,354 adults (including 4868 LGB adults) from the 2015 and 2016 National Survey on Drug Use and Health (NSDUH), we examined LGB disparities in lifetime and recent use of cigarettes, marijuana, and illicit drugs. Analyses were stratified by age groups (18-25, 26-34, and 35-49 years) and compared lesbian/gay (L/G) and bisexual adults, respectively, with heterosexual adults of the same gender and age group. Results: Among L/G women, disparities (relative to same-age heterosexual women) were significantly larger in the youngest age group compared with the older age groups for numerous measures of lifetime and recent SU. Conversely, among bisexual men and bisexual women, multiple SU disparities (relative to heterosexual adults of the same age and gender) were significantly smaller among the youngest age group compared with the oldest age group. Conclusion: Contrary to hypotheses of decreased minority stress among more recent generations of LGB individuals, we found that SU disparities were not systematically smaller in younger age groups. Rather, disparities exhibited distinct trends across age groups. As NSDUH data are cross-sectional, differences by age group may reflect the influence of both age-varying developmental factors as well as time-varying social and contextual factors.
