Group sex is relatively common among gay men, and is a likely risk factor for infection with HIV and other sexually transmissible infections (STI). The 5,432 participants in the 2008 Gay Community Periodic Survey in Sydney, Melbourne and Brisbane, Australia, were asked about their participation in group sex. Nearly half (44.0%) of those who reported sex with casual male partners in the previous 6 months also reported engaging in group sex. Among other factors, using drugs odds ratios (OR) and confidence intervals (CI) (OR = 1.89, CI = 1.61-2.21), being HIV-positive (OR = 1.62, CI = 1.13-2.32), and engaging in anal intercourse, both with a condom (OR = 3.03, CI = 2.46-3.73) and without a condom (OR = 5.68, CI = 4.53-7.12) were independently associated with having engaged in group sex. This study suggests that gay men who engage in group sex represent an important priority for targeted HIV and STI prevention activities and research.
群体性行为在男同性恋者中较为常见,是感染艾滋病毒和其他性传播感染(STI)的一个可能的风险因素。2008 年澳大利亚悉尼、墨尔本和布里斯班的同性恋社区定期调查的 5432 名参与者被问及他们是否参与过群体性行为。在过去 6 个月报告与随意男性伴侣发生性行为的人中,近一半(44.0%)也报告有过群体性行为。在其他因素中,使用毒品的比值比(OR)和置信区间(CI)(OR=1.89,CI=1.61-2.21),HIV 阳性(OR=1.62,CI=1.13-2.32),以及进行肛交,无论是使用避孕套(OR=3.03,CI=2.46-3.73)还是不使用避孕套(OR=5.68,CI=4.53-7.12),都与参与群体性行为独立相关。这项研究表明,参与群体性行为的男同性恋者是针对艾滋病毒和性传播感染(STI)预防活动和研究的一个重要重点。
