OBJECTIVE Sexual minority (i.e., lesbian, bisexual) women and racial-ethnic minority groups in the United States are disproportionately harmed by excessive alcohol use. This study examined disparities in excessive alcohol use at the intersection of race-ethnicity and sexual identity for non-Hispanic Black and Hispanic sexual minority women. METHOD Using data from the 2015 National Survey on Drug Use and Health, we compared the age-adjusted prevalence of binge drinking and heavy alcohol use among sexual minority women of color, sexual minority White women, and heterosexual women of color with that of White heterosexual women. The joint disparity is the difference in the prevalence of excessive alcohol use between sexual minority women of color and White heterosexual women. The excess intersectional disparity is the portion of the joint disparity that is due to being both a racial-ethnic minority and a sexual minority woman. RESULTS Black and Hispanic sexual minority women reported the highest prevalence of binge drinking (45.4% and 43.4%, respectively), followed by White sexual minority women (35.7%) and White heterosexual women (23%). Black and Hispanic heterosexual women reported the lowest prevalence of binge drinking (20.8% and 20.2%, respectively). The joint disparity in binge drinking between Black sexual minority women and White heterosexual women was 21.2%, and the excess intersectional disparity was 17.7%. The joint disparity in binge drinking between Hispanic sexual minority women and White heterosexual women was 16.8%, and the excess intersectional disparity was 10.8%. CONCLUSIONS Disparities in excessive alcohol consumption for Black and Hispanic sexual minority women, compared with White heterosexual women, were larger than what would be expected when considering differences by race or sexual identity individually.

目的在美国，过度饮酒会严重危害性少数群体（即女同性恋，双性恋）妇女和种族少数群体。这项研究调查了非西班牙裔黑人和西班牙裔性少数族裔妇女在种族种族和性认同相交的地方过度饮酒的差异。方法使用2015年全国药物使用和健康调查的数据，我们比较了有色人种，有色人种的白人妇女和有色人种的异性恋妇女与异性恋白人妇女的年龄调整后的暴饮和重度酗酒的患病率女人。共同的差异是有色性少数族裔女性和白人异性恋女性之间过度饮酒的患病率之间的差异。交叉差异过大是关节差异的一部分，这是由于既是种族少数群体妇女又是性少数群体妇女。结果黑人和西班牙裔少数族裔妇女的狂欢饮酒发生率最高（分别为45.4％和43.4％），其次是白人少数族裔妇女（35.7％）和白人异性恋妇女（23％）。黑人和西班牙裔异性恋妇女的狂欢饮酒率最低（分别为20.8％和20.2％）。黑人性少数族裔妇女与白人异性恋妇女之间的暴饮暴食联合差距为21.2％，而多余的交叉差距为17.7％。西班牙裔少数族裔妇女与白人异性恋妇女之间的暴饮暴食联合差距为16.8％，而交叉交叉差距为10.8％。
