中国正在经历一个新的艾滋病毒流行的男男性行为者（MSM）。我们调查了北京市首次大样本的男男性行为者的性风险、风险认知、艾滋病和安全套知识以及预防服务的利用情况。从2001年9月至2002年1月，对482名男男性行为者进行了抽样调查。49%的参与者报告在过去6个月内与男性进行过无保护的肛交。然而，只有15%的人认为他们有感染艾滋病毒的风险，许多人对艾滋病毒的传播途径有误解，对安全套的知识有限。在过去两年中，不到四分之一的人获得免费避孕套（24%）和避孕套润滑剂（19%）。多因素Logistic回归分析显示，无北京户口、有6名以上男性性伴、无女性性行为史、有性病史、未做过HIV检测是无保护插入肛交的危险因素。无保护的接受性肛交与有六个或更多男性性伴侣、不与女性发生性关系、有性病终生史、从未接受过艾滋病毒检测以及较少接触艾滋病毒预防服务独立相关。此外，28%的人报告在过去6个月内与男性和女性都发生过性行为，11%的人与男性和女性都发生过无保护的性行为。这一发现表明，男男性行为者是艾滋病毒传播到异性恋妇女（或反之亦然）的潜在桥梁，解决男男性行为者的艾滋病毒预防需求可能会使更广泛的人群受益。
China is experiencing an emerging HIV epidemic among men who have sex with men (MSM). We investigated sexual risk, risk perception, HIV and condom knowledge, and utilization of prevention services in the first large sample of MSM recruited in Beijing. Four hundred eighty-two MSM were sampled from September 2001 to January 2002. Forty-nine percent of participants reported unprotected anal intercourse with men during the previous 6 months. However, only 15% perceived they are at risk for HIV and many had misconceptions about HIV transmission routes and limited knowledge about condoms. Less than one quarter obtained free condoms (24%) and condom lubricants (19%) in the past 2 years. Multiple logistic regression analysis showed that unprotected insertive anal intercourse was associated with not having a Beijing residence card, having six or more male sexual partners, not having sex with women, having a lifetime history of sexually transmitted diseases (STDs), and having never tested for HIV. Unprotected receptive anal intercourse was independently associated with having six or more male sexual partners, not having sex with women, having a lifetime history of STDs, having never tested for HIV, and having less exposure to HIV prevention services. In addition, 28% reported having sex with both men and women during the previous 6 months, and 11% had unprotected intercourse with both men and women. This finding suggests that MSM are a potential bridge of HIV transmission to heterosexual women (or vice versa) and that addressing the HIV prevention needs of MSM may benefit the wider population.
