The purpose of this study was to examine relationships between sexual orientation-based discrimination and excessive alcohol use and substance use disorders and to identify how these relationships differ by sexual identity, sex, race, Hispanic origin, and education among sexual minorities.
We used logistic regression to analyze associations between discrimination and substance use measures among 1351 gay/lesbian, bisexual, or unsure adults from a nationally representative survey. Differential effects by sexual identity, sex, race, Hispanic origin, and education were assessed using interaction models followed by stratified models.
Discrimination was associated with increased odds of the following: exceeding weekly drinking limits [adjusted odds ratio (aOR) = 1.52, 95% confidence interval (CI): 1.12-2.08] among bisexuals, any substance use disorder (aOR = 2.04, 95% CI: 1.41-2.95) and nicotine use disorder (aOR = 1.52, 95% CI: 1.08-2.14) among Hispanic sexual minorities, and exceeding weekly drinking limits (aOR = 1.56, 95% CI: 1.08-2.26) among those with a high school degree or less.
Sexual orientation-based discrimination was associated with select substance use outcomes, especially among bisexuals, Hispanics, and less educated sexual minority adults, highlighting potential disparities associated with experiencing discrimination.
本研究旨在探讨性取向歧视与酗酒和物质使用障碍之间的关系，并确定这些关系在性少数群体中如何因性认同、性别、种族、西班牙裔血统和教育程度而有所不同。
我们使用逻辑回归分析了来自全国代表性调查的 1351 名同性恋/双性恋或不确定成年人中歧视与物质使用措施之间的关联。使用交互模型和分层模型评估了性认同、性别、种族、西班牙裔血统和教育程度的差异效应。
歧视与以下情况的几率增加有关：双性恋者超过每周饮酒限制（调整后的优势比[aOR] = 1.52，95%置信区间[CI]：1.12-2.08），西班牙裔性少数群体中的任何物质使用障碍（aOR = 2.04，95% CI：1.41-2.95）和尼古丁使用障碍（aOR = 1.52，95% CI：1.08-2.14），以及高中及以下学历者超过每周饮酒限制（aOR = 1.56，95% CI：1.08-2.26）。
性取向歧视与某些物质使用结果有关，尤其是在双性恋者、西班牙裔和受教育程度较低的性少数群体成年人中，这突显了与经历歧视相关的潜在差异。
