男女发生性行为 (MSMW) 的黑人男性感染和传播艾滋病毒的风险很高。这项研究比较了自报艾滋病毒阳性的黑人 MSMW 与自报艾滋病毒阴性和不知道自己艾滋病毒状况的黑人 MSMW 的性危险行为。采用受访者驱动抽样 (RDS) 方法在费城和纽约招募了 1,154 名黑人 MSM，他们完成了音频计算机辅助自我访谈 (ACASI)。在这些男性中，有 212 人在过去 3 个月内与男性伴侣进行过肛交，以及与女性伴侣进行过阴道性交或肛交。四分之一（23.6%；n = 50）的 MSMW 自我报告在上次检测中 HIV 检测呈阳性，59.4%（n = 126）报告在上次检测中 HIV 检测呈阴性，17.0%（n = 36）报告从未进行过 HIV 检测。多变量逻辑回归分析显示，与艾滋病毒阴性男性和从未检测过的男性相比，艾滋病毒阳性 MSMW 与被认为艾滋病毒阴性或血清状态未知的主要男性和主要女性伴侣进行无保护性交的可能性要小得多。然而，艾滋病毒阳性男性与艾滋病毒阴性男性同样有可能与被视为艾滋病毒阴性或血清状态未知的非主要男性和非主要女性伴侣进行无保护性交。我们的研究结果表明，一些艾滋病毒呈阳性的 MSMW 进行无保护的性行为，使女性和男性伴侣面临感染艾滋病毒的风险。然而，从未接受过 HIV 检测或最近未接受过检测的 MSMW 可能是将 HIV 传播给其女性和男性伴侣的更大来源。
Black men who have sex with men and women (MSMW) are at high risk for HIV infection and transmission. This study compared the sexual risk behaviors of Black MSMW who self-reported being HIV-positive with those who reported being HIV-negative and those who did not know their HIV status. Respondent-driven sampling (RDS) was used to recruit 1,154 Black MSM in Philadelphia and New York who completed an audio computer-assisted self-interview (ACASI). Of these men, 212 had engaged in anal sex with male partners and vaginal or anal sex with female partners in the past 3 months. A quarter (23.6%; n = 50) of MSMW self-reported testing positive for HIV at their last test, 59.4% (n = 126) reported testing negative for HIV at their last test, and 17.0% (n = 36) reported never having an HIV test. Multivariate logistic regression analysis revealed that HIV-positive MSMW were much less likely than HIV-negative men and never-tested men to have engaged in unprotected intercourse with main male and main female partners perceived to be HIV-negative or of unknown serostatus. However, HIV-positive men were equally as likely as HIV-negative men to have unprotected intercourse with non-main male and non-main female partners perceived as HIV-negative or of unknown serostatus. Our findings indicate that some HIV-positive MSMW engage in unprotected sex that places female and male partners at risk for HIV infection. However, MSMW who have never taken an HIV test, or who have not been recently tested, may be a greater source of HIV transmission to their female and male partners.
