目的：这项研究评估了纽约市HIV阳性同性恋和双性恋男人的未受保护的肛门和口交行为，以及他们的主要和非媒体性伴侣。在这里，我们专注于使用三种减少危害策略（射精，战略定位和射精前退出），以降低传输风险。方法：来自两个城市的1168 HIV阳性同性恋者基线评估的数据，被利用。男性是通过广告和其他技术从各种基于社区的场所招募的：发现城市差异，与纽约市的男人相比，旧金山的男性越来越多地报告了所有合作伙伴类型的性风险行为。鉴定出塞罗塞治疗，男性与其他HIV阳性伴侣相比，与与HIV阴性的伴侣相比，与其他HIV阳性伴侣的口腔和肛交行为更大。但是，与其他伴侣相比，男性还报告了与未知地位的伴侣更加无保护的性行为。尽管在各个城市和不同类型的伙伴之间都发现了一些战略定位的证据，尽管存在差异。这两个城市的男性报告没有射精的口交行为多于射精，但是在旧金山的男性中，将戒断作为减少肛交的危害策略更为普遍：总体而言，确定了减少伤害的证据；但是，发现两个城市之间存在显着差异。讨论了同性恋和双性恋男人的性行为的复杂性，这些发现对预防工作和未来的研究具有重要意义。 （c）2005 Lippincott Williams＆Wilkins。
Objective: This study assessed unprotected anal and oral sex behaviors of HIV-positive gay and bisexual men in New York City and San Francisco with their main and nonmain sexual partners. Here we focus on the use of three harm reduction strategies (serosorting, strategic positioning, and withdrawal before ejaculation) in order to decrease transmission risk.Method: The data from a baseline assessment of 1168 HIV-positive gay and bisexual men in the two cities,were utilized. Men were recruited from a variety of community-based venues, through advertising and other techniques.Results: City differences were identified, with more men in San Francisco reporting sexual risk behaviors across all partner types compared with men in New York City. Serosorting was identified, with men reporting significantly more oral and anal sex acts with other HIV-positive,partners than with HIV-negative partners. However, men, also reported more unprotected sex with partners of unknown status compared with their other partners. Some evidence of strategic positioning was identified, although differences were noted across cities and across different types of partners. Men in both cities reported more acts of oral sex without ejaculation than with ejaculation, but the use of withdrawal as a harm reduction strategy for anal sex was more common among men from San Francisco.Conclusion: Overall, evidence for harm reduction was identified; however, significant differences across the two cities were found. The complicated nature of the sexual practices of gay and bisexual men are discussed, and the findings have important implications for prevention efforts and future research studies.
