背景资料：以前的研究特征性少数物质使用的差异主要比较女同性恋/男同性恋和双性恋的个人，分别或组合，异性恋的个人。鉴于新出现的证据表明，双性恋者可能有特别高的物质使用风险，我们研究了双性恋和女同性恋/男同性恋者之间的差异，最近的物质使用使用全国调查data.Methods：数据126,463成人（包括8241 LGB成人）是从2015-2017年全国药物使用和健康调查。物质使用结局包括酗酒、吸烟、雪茄吸烟、大麻使用、非法药物使用、阿片类药物滥用、酒精使用障碍、尼古丁依赖和物质使用障碍。Logistic回归用于估计性别身份和性别特异性比值比，控制人口统计学特征。特别感兴趣的是估计比较双性恋和女同性恋/男同性恋个体的同一gender.Results：男性和女性性少数成年人有显着升高的物质使用率相比，异性恋成年人。此外，相对于女同性恋/男同性恋女性，双性恋女性的酗酒（aOR = 1.29），大麻使用（aOR = 1.42），非法药物使用（aOR = 1.55），阿片类药物滥用（aOR = 1.53）和酒精使用障碍（aOR = 1.48）的几率显着增加。相对于男同性恋者，双性恋男性有显着升高雪茄的使用（aOR = 1.64）。结论：双性恋女性是在显着更大的风险，相对于女同性恋者/男同性恋者的多种物质使用行为。我们没有观察到任何物质使用行为，双性恋者的风险显着低于他们的女同性恋/男同性恋同龄人。这些差异可能在一定程度上可以由双性恋者（尤其是双性恋女性）使用药物的独特风险因素来解释。
Background: Prior studies characterizing sexual minority substance use disparities have primarily compared lesbian/gay and bisexual individuals, respectively or in combination, to heterosexual individuals. In light of emerging evidence that bisexual individuals may have particularly elevated substance use risk, we examine differences in recent substance use between bisexual and lesbian/gay individuals using national survey data.Methods: Data on 126,463 adults (including 8241 LGB adults) were from the 2015-2017 National Survey on Drug Use and Health. Substance use outcomes included binge drinking, cigarette smoking, cigar smoking, marijuana use, illicit drug use, opioid misuse, alcohol use disorder, nicotine dependence, and substance use disorder. Logistic regression was used to estimate sexual identity- and gender-specific odds ratios, controlling for demographic characteristics. Of particular interest were estimates comparing bisexual and lesbian/gay individuals of the same gender.Results: Both male and female sexual minority adults had significantly elevated rates of substance use compared to heterosexual adults. Furthermore, relative to lesbian/gay women, bisexual women had significantly elevated odds of binge drinking (aOR = 1.29), marijuana use (aOR = 1.42), illicit drug use (aOR = 1.55), opioid misuse (aOR = 1.53), and alcohol use disorder (aOR = 1.48). Relative to gay men, bisexual men had significantly elevated cigar use (aOR = 1.64).Conclusions: Bisexual women were at significantly greater risk for multiple substance use behaviors relative to lesbian/gay women. We did not observe any substance use behaviors for which bisexual individuals had significantly lower risk than their lesbian/gay peers. These disparities may be explained, in part, by unique risk factors for substance use experienced by bisexual individuals, particularly bisexual women.
