Burgeoning research suggests a link between suicidality (i.e., ideation, attempts) and cannabis use; however, little is known about which demographic groups are at increased risk of co-occurring suicidality and cannabis use disorders (CUD). This study tested differences in suicidality, CUD, and their co-occurrence by gender, age, race/ethnicity, and sexual orientation in a nationally representative U.S.
Five years (2015-2019) of National Survey of Drug Use and Heath surveys were combined. Multinomial logistic regressions tested demographic differences in odds of suicidality only, CUD only, and co-occurring CUD and suicidality, relative to neither suicidality nor CUD. Covariates included survey year, major depressive episode, and other substance use disorders.
Men had higher odds of co-occurring suicidal ideation and CUD than women (AOR = 2.06). All older age groups reported lower odds of co-occurring suicidal ideation and CUD and co-occurring suicide attempts and CUD than emerging adults (AORs = 0.06-0.39). Black/African American (AOR = 1.42) and Native (AOR = 2.16) adults reported higher odds of co-occurring suicidal ideation and CUD than White adults. Black/African American (AOR = 4.05) and Hispanic/Latinx (AOR = 2.49) adults reported higher odds of co-occurring CUD and suicide attempts than White adults. Gay/lesbian (AOR = 2.04) and bisexual (AOR = 3.16) adults reported higher odds of co-occurring suicidal ideation and CUD than heterosexual adults.
Men, emerging adults, Black/African American, Native, and sexual minority groups had elevated risk of co-occurring suicidal ideation and CUD. Emerging adults, Black/African American, and Hispanic/Latinx groups had elevated risk of co-occurring suicide attempts and CUD.
大量研究表明自杀意念（即想法、尝试）与大麻使用之间存在关联；然而，对于哪些人群更容易同时出现自杀意念和大麻使用障碍（CUD）知之甚少。本研究通过性别、年龄、种族/民族和性取向测试了全国代表性美国人群中自杀意念、CUD 及其共病的差异。
将五年（2015-2019 年）的国家药物使用与健康调查数据合并。多项逻辑回归检验了相对于既无自杀意念也无 CUD 而言，自杀意念仅、CUD 仅和 CUD 与自杀意念共病的情况下，人口统计学差异的可能性。协变量包括调查年份、重度抑郁发作和其他物质使用障碍。
与女性相比，男性同时出现自杀意念和 CUD 的可能性更高（AOR=2.06）。所有年龄较大的群体报告同时出现自杀意念和 CUD 以及同时出现自杀企图和 CUD 的可能性均低于新兴成年人（AORs=0.06-0.39）。黑种/非裔美国人和原住民（AOR=1.42）比白人成年人报告同时出现自杀意念和 CUD 的可能性更高。黑种/非裔美国人和西班牙裔/拉丁裔（AOR=2.49）比白人成年人报告同时出现 CUD 和自杀企图的可能性更高。同性恋/女同性恋（AOR=2.04）和双性恋（AOR=3.16）比异性恋成年人报告同时出现自杀意念和 CUD 的可能性更高。
男性、新兴成年人、黑种/非裔美国人、原住民和性少数群体同时出现自杀意念和 CUD 的风险增加。新兴成年人、黑种/非裔美国人和西班牙裔/拉丁裔群体同时出现自杀企图和 CUD 的风险增加。
