更多的女同性恋,男同性恋和双性恋(LGB)青年比异性恋者报告物质使用。我们研究了一个理论模型,以了解这些差异的一生和过去一年的物质使用的压力和附件的范例,使用纵向成长今天的研究(GUTS)和护士的健康研究II(NHSII)。全球统一测试系统的参与者是参加国家卫生服务第二阶段的参与者的子女;因此,可以获得儿童和母亲的数据。此外,GUTS包含兄弟姐妹,允许LGB和异性恋兄弟姐妹的比较。在5,647名GUTS青年(2005年男性= 20.6岁)中,1.6%是女同性恋/男同性恋(LG),1.6%是双性恋(BI),9.9%是异性恋(MH),86.9%是完全异性恋(CH)。在调整GUTS和协变量的兄弟姐妹聚类后,比CH报告的一生和过去一年吸烟,非大麻非法药物使用和处方药滥用的性少数群体(LG,BI和MH)显着更多。在过去的一年里,更多的性少数群体也报告了大麻的使用。性取向和物质使用之间的关系是缓和的压力标记:随着母亲的不适与同性恋增加,更多的BI和MH比CH使用的物质。随着儿童期性别歧视行为的增加,更多的LG比CH使用物质。性取向和物质使用之间的关系是由依恋和母亲的感情介导的(中介效应的百分比范围从5.6%-16.8%%的终身物质使用和4.9%-24.5%的过去一年的使用)。此外,兄弟姐妹的比较发现,性少数报告更多的物质使用,更多的童年性别歧视行为,和不安全的附件比CH兄弟姐妹;母亲报告较少的感情,他们的性少数比CH后代。研究结果表明,压力和依恋范式的重要性,了解性取向的差异,在物质使用。
More lesbian, gay, and bisexual (LGB) youths than heterosexuals report substance use. We examined a theoretical model to understand these disparities in lifetime and past-year substance use by means of stress and attachment paradigms, using the longitudinal Growing Up Today Study (GUTS) and Nurses’ Health Study II (NHSII). GUTS participants are the children of participants in NHSII; thus, child and maternal data are available. In addition, GUTS contains siblings, allowing for comparisons of LGB and heterosexual siblings. Of 5,647 GUTS youths (M = 20.6 years old in 2005), 1.6% were lesbian/gay (LG), 1.6% bisexual (BI), 9.9% mostly heterosexual (MH), and 86.9% completely heterosexual (CH). After adjusting for sibling clustering in GUTS and covariates, significantly more sexual minorities (LGs, BIs, and MHs) than CHs reported lifetime and past-year smoking, non-marijuana illicit drug use, and prescription drug misuse. More sexual minorities also reported marijuana use in the past year. The relations between sexual orientation and substance use were moderated by the stress markers: As mother's discomfort with homosexuality increased, more BIs and MHs than CHs used substances. As childhood gender nonconforming behaviors increased, more LGs than CHs used substances. The relations between sexual orientation and substance use were mediated by attachment and maternal affection (percent of effect mediated ranged from 5.6%–16.8%% for lifetime substance use and 4.9%–24.5% for past-year use). In addition, sibling comparisons found that sexual minorities reported more substance use, more childhood gender nonconforming behaviors, and less secure attachment than CH siblings; mothers reported less affection for their sexual-minority than CH offspring. The findings indicate the importance of stress and attachment paradigms for understanding sexual-orientation disparities in substance use.
