To explore demographic, behavioral and psychosocial risk factors for HIV infection in South African MSM we recruited 480 MSM (aged 18 and 44 years) using respondent-driven sampling. Data were collected through individual computer-assisted face-to-face interviews. Participants were tested for HIV. RDS-adjusted HIV prevalence is 30.1 % (unadjusted 35.6 %). Few participants had ever engaged in both receptive and insertive anal sex; sex with women was frequently reported. Independent demographic and behavioral correlates of HIV infection include age, education, number of male sexual partners, ever having been forced to have sex, and ever having engaged in transactional sex; engagement in sex with women was a protective factor. Psychosocial risk factors independently associated with HIV infection were feminine identification, internalized homophobia, and hazardous drinking. Our findings confirm what has been found in other studies, but also suggest that the dynamics and context of sexual transmission among MSM in South Africa differ from those among MSM in Western countries.
为探讨南非男男性行为者（MSM）感染艾滋病毒的人口统计学、行为和心理社会风险因素，我们采用应答者驱动抽样方法招募了480名MSM（年龄在18至44岁之间）。通过个人计算机辅助面对面访谈收集数据。对参与者进行了艾滋病毒检测。经应答者驱动抽样调整后的艾滋病毒感染率为30.1%（未调整为35.6%）。很少有参与者既进行过接受性肛交又进行过插入性肛交；经常有与女性发生性行为的报告。艾滋病毒感染的独立人口统计学和行为相关因素包括年龄、教育程度、男性性伴侣数量、曾被迫发生性行为以及曾进行过交易性性行为；与女性发生性行为是一个保护因素。与艾滋病毒感染独立相关的心理社会风险因素是女性化认同、内化的恐同心理和有害饮酒。我们的研究结果证实了其他研究的发现，但也表明南非MSM中性传播的动态和背景与西方国家的MSM不同。
