目标。我们试图在男男性行为者的概率样本中确定HIV的流行率和新的高危传播行为的辅助因素。我们对旧金山1976名成年男男性接触者进行了横断面电话调查。我们发现艾滋病毒的流行率为25.2%。在感染艾滋病毒的男性中，与血清不一致(不具有相同艾滋病毒/艾滋病血清状态)的伴侣进行无保护插入式肛交的预测因素包括在过去12个月中使用伟哥和伴侣数量较多。在未知感染艾滋病毒的男性中，与血清不一致的伴侣进行无保护的接受性肛交独立地与在旧金山生活不到1年、使用冰毒晶体和亚硝酸戊酯、伴侣数量更多以及同意这样的说法有关：“与几年前相比，你在性或药物方面不再那么谨慎，因为现在有更好的艾滋病毒治疗方法。”城市男男性接触者预防艾滋病毒的战略应侧重于艾滋病毒传播的新预测因素。
Objectives. We sought to determine the prevalence of HIV and novel cofactors of high-transmission-risk behavior in a probability sample of men who have sex with men WSM).Methods. We performed a cross-sectional telephone survey of 1976 adult MSM in San Francisco.Results. We found an HIV prevalence of 25.2%. Predictors of unprotected insertive anal intercourse with a serodiscordant (not having the same HIV/AIDS serostatus) partner among HIV-infected men included use of Viagra and a greater number of partners in the past 12 months. Unprotected receptive anal intercourse with a serodiscordant partner among men not known to be HIV infected was independently associated with having lived in San Francisco for less than 1 year, use of crystal methamphetamine and amyl nitrites, a greater number of partners, and agreement with the statement, "You are less careful about being safe with sex or drugs than you were several years ago because there are better treatments for HIV now."Conclusions. Strategies to prevent HIV for urban MSM should focus on new predictors of HIV transmission.
