This study examined demographic characteristics, sexual risk behaviors, sexual beliefs, and substance use patterns in HIV-positive, methamphetamine-using men who have sex with both men and women (MSMW) (n = 50) as compared to men who have sex with men only (MSM) (n = 150). Separate logistic regressions were conducted to predict group membership. In the final model, of 12 variables, eight were independently associated with group membership. Factors independently associated with MSMW were acquiring HIV through injection drug use, being an injection drug user, using hallucinogens, using crack, being less likely to have sex at a bathhouse, being less likely to be the receptive partner when high on methamphetamine, having greater intentions to use condoms for oral sex, and having more negative attitudes about HIV disclosure. These results suggest that, among HIV-positive methamphetamine users, MSMW differ significantly from MSM in terms of their HIV risk behaviors. Studies of gay men and HIV often also include bisexual men, grouping them all together as MSM, which may obscure important differences between MSMW and MSM. It is important that future studies consider MSM and MSMW separately in order to expand our knowledge about differential HIV prevention needs for both groups. This study showed that there were important differences in primary and secondary prevention needs of MSM and MSMW. These findings have implications for both primary and secondary HIV prevention among these high-risk populations.
本研究调查了艾滋病毒阳性、同时与男性和女性发生性行为的甲基苯丙胺使用者(MSMW)(n=50)与仅与男性发生性行为的男性(MSM)(n=150)之间的人口统计学特征、性风险行为、性信仰和物质使用模式。分别进行了逻辑回归以预测群体归属。在最终模型中,在 12 个变量中,有 8 个与群体归属独立相关。与 MSMW 独立相关的因素包括通过注射吸毒感染艾滋病毒、注射吸毒者、使用迷幻剂、使用冰毒、不太可能在浴室发生性行为、在吸食冰毒时不太可能处于接受方、更倾向于使用避孕套进行口交以及对艾滋病毒披露有更多负面态度。这些结果表明,在艾滋病毒阳性的甲基苯丙胺使用者中,MSMW 在 HIV 风险行为方面与 MSM 有显著差异。对男同性恋者和艾滋病毒的研究通常也包括双性恋男性,将他们全部归为 MSM,这可能掩盖了 MSMW 和 MSM 之间的重要差异。重要的是,未来的研究应分别考虑 MSM 和 MSMW,以扩大我们对这两个群体不同的 HIV 预防需求的了解。本研究表明,MSM 和 MSMW 在一级和二级预防需求方面存在重要差异。这些发现对这些高危人群的一级和二级艾滋病毒预防都有影响。
