Subst Use Misuse. 2018 Mar 21;53(4):559-564. doi: 10.1080/10826084.2017.1347185. Epub 2017 Sep 15.
Internalized homonegativity may promote substance use among U.S. men who have sex with men only (MSMO) and men who have sex with men and women (MSMW). However, studies have produced mixed findings, used non-representative samples, and not adequately examined MSMW.
We investigated (1) internalized homonegativity in relation to substance use and (2) the extent of temporal change in internalized homonegativity among MSMO and MSMW.
Using merged 2002, 2006-2010, and 2011-2013 cycles of the National Survey of Family Growth-a nationally representative U.S. sample of persons aged 15-44 years-we acquired subsamples of MSMO (n = 419) and MSMW (n = 195). Rao-Scott chi-square tests examined internalized homonegativity in relation to past-month binge drinking and use of marijuana. These tests examined past-year use of any illicit substance, cocaine, crack, injection drugs, and methamphetamine. Multivariable logistic regression models controlled for covariates. Rao-Scott chi-square tests examined temporal changes in internalized homonegativity.
Among MSMO, internalized homonegativity was associated with increased odds of using any illicit substance, cocaine, and methamphetamine. Among MSMW, however, internalized homonegativity was associated with decreased odds of using any illicit substance, cocaine, crack, injection drugs, and methamphetamine. The proportion of MSMO and MSMW who expressed internalized homonegativity did not significantly change during 2002-2013. Conclusions/Importance: Internalized homonegativity may be positively associated with substance use among MSMO, but negatively associated with substance use among MSMW. Future studies should seek to better understand internalized homonegativity and other determinants of substance use among MSMO and MSMW.
内化的同性恋消极观念可能会促使仅与男性发生性关系的美国男性（MSMO）以及与男性和女性都发生性关系的男性（MSMW）使用毒品。然而，研究结果不一，样本缺乏代表性，且未对MSMW进行充分研究。
我们调查了（1）内化的同性恋消极观念与毒品使用之间的关系，以及（2）MSMO和MSMW内化的同性恋消极观念的时间变化程度。
利用2002年、2006 - 2010年以及2011 - 2013年合并的全国家庭成长调查周期数据——这是一个具有全国代表性的15 - 44岁美国人群样本——我们获取了MSMO（n = 419）和MSMW（n = 195）的子样本。Rao - Scott卡方检验考察了内化的同性恋消极观念与过去一个月的狂饮及大麻使用之间的关系。这些检验还考察了过去一年中任何非法药物、可卡因、快克、注射毒品和甲基苯丙胺的使用情况。多变量逻辑回归模型对协变量进行了控制。Rao - Scott卡方检验考察了内化的同性恋消极观念的时间变化。
在MSMO中，内化的同性恋消极观念与使用任何非法药物、可卡因和甲基苯丙胺的几率增加有关。然而，在MSMW中，内化的同性恋消极观念与使用任何非法药物、可卡因、快克、注射毒品和甲基苯丙胺的几率降低有关。在2002 - 2013年期间，表达内化的同性恋消极观念的MSMO和MSMW的比例没有显著变化。结论/重要性：内化的同性恋消极观念可能与MSMO中的毒品使用呈正相关，但与MSMW中的毒品使用呈负相关。未来的研究应致力于更好地理解内化的同性恋消极观念以及MSMO和MSMW中其他毒品使用的决定因素。
