To explore differences in demographic characteristies, risk practices, and preventive behaviors among subgroups of men who have sex with men (MSM), including gay- and non-gay-identified MSM, MSM who inject drugs, and those engaging in sex hustling.
A secondary analysis of cross-sectional data collected through interviewer-administered questionnaires in a purposive sample of MSM.
Gay bars, bath houses, adult video arcades, and out-door crusing areas in Denver and Long Beach.
Men who reported oral or anal sex with another man in the past year with oversampling of non-gay-identified MSM.
Of 1,290 MSM, 417 (32%) did not gay-identify, 86 (7%) were drug injectors, and 117 (9%) were hustlers. Of drug-injecting MSM, 55% reported sex hustling and 40% of hustlers reported injection drug use. Hustling was associated with higher number of partners, more frequent anal sex with men and women, and less frequent condom use during anal sex with occasional male partners. Hustlers and drug-injecting MSM used condoms less consistently during vaginal intercourse with female partners than did other MSM.
Among MSM, subgroups at particularly high risk for HIV can be identified. Although these subgroups may be relatively small, they may be important epidemiologic links to the larger MSM and heterosexual communities and warrant focused behavioral interventions to prevent the further spread of HIV.
探讨男男性行为者(MSM)亚组之间在人口统计学特征、风险行为及预防行为方面的差异,这些亚组包括自我认同为同性恋和非同性恋的MSM、注射毒品的MSM以及从事性交易的MSM。
对通过访谈式问卷收集的横断面数据进行二次分析,该数据来自于有目的抽样的MSM。
丹佛和长滩的同性恋酒吧、澡堂、成人录像厅及户外寻欢场所。
过去一年中报告与另一名男性有口交或肛交行为的男性,对自我认同为非同性恋的MSM进行了过度抽样。
在1290名MSM中,417名(32%)不自我认同为同性恋,86名(7%)为注射毒品者,117名(9%)从事性交易。在注射毒品的MSM中,55%报告从事性交易,而从事性交易的MSM中有40%报告注射毒品。从事性交易与更多的性伴侣数量、更频繁地与男性及女性进行肛交以及与偶尔的男性性伴侣进行肛交时较少使用避孕套有关。从事性交易的MSM和注射毒品的MSM在与女性伴侣进行阴道性交时使用避孕套的频率低于其他MSM。
在MSM中,可以识别出感染HIV风险特别高的亚组。尽管这些亚组可能相对较小,但它们可能是与更大的MSM群体及异性恋群体重要的流行病学联系纽带,需要有针对性的行为干预措施来防止HIV的进一步传播。
