There is a continuing need to identify factors associated with risk for HIV transmission among men who have sex with men (MSM), including a need for further research in the ongoing scientific debate about the association of internalised homophobia and sexual risk due partly to the lack of specificity in analysis. We assess the association of internalised homophobia by race/ethnicity within HIV serostatus for a large sample of substance-using MSM at high risk of HIV acquisition or transmission.
Convenience sample of substance-using (non-injection) MSM reporting unprotected anal sex in the prior 6 months residing in Chicago, Los Angeles, New York and San Francisco. The analytic sample included HIV-negative and HIV-positive black (n=391), Latino (n=220), and white (n=458) MSM. Internalised homophobia was assessed using a published four-item scale focusing on negative self-perceptions and feelings of their own sexual behaviour with men, or for being gay or bisexual. Analyses tested associations of internalised homophobia with recent risk behaviour, stratified by laboratory-confirmed HIV serostatus within race/ethnicity, and controlling for other demographic variables.
In multivariate analysis, internalised homophobia was inversely associated (p<0.05) with recent unprotected anal sex among black MSM, and not significantly associated with sexual risk behaviour among white and Latino MSM.
More research is needed to further identify nuanced differences in subpopulations of MSM, but these results suggest differentially targeted intervention messages for MSM by race/ethnicity.
持续需要确定男男性行为者(MSM)中与HIV传播风险相关的因素,包括在关于内化恐同症与性风险关联的 ongoing scientific debate 中需要进一步研究,部分原因是分析缺乏特异性。我们针对大量有感染或传播HIV高风险的吸毒MSM样本,评估按种族/族裔划分的内化恐同症与HIV血清学状态之间的关联。
对居住在芝加哥、洛杉矶、纽约和旧金山的在过去6个月内报告有无保护肛交行为的吸毒(非注射)MSM进行便利抽样。分析样本包括HIV阴性和HIV阳性的黑人(n = 391)、拉丁裔(n = 220)和白人(n = 458)MSM。使用已发表的一个包含四项的量表评估内化恐同症,该量表侧重于对自身与男性发生性行为、或身为同性恋或双性恋者的负面自我认知和感受。分析测试了内化恐同症与近期风险行为之间的关联,按种族/族裔内实验室确认的HIV血清学状态分层,并控制其他人口统计学变量。
在多变量分析中,内化恐同症与黑人MSM近期的无保护肛交呈负相关(p < 0.05),与白人和拉丁裔MSM的性风险行为无显著关联。
需要更多研究来进一步确定MSM亚群体中的细微差异,但这些结果表明应按种族/族裔为MSM制定有针对性的干预信息。
