To determine HIV prevalence and associated risk factors among men who have sex with men (MSM) in Abidjan, Côte d'Ivoire. We conducted a cross-sectional RDS survey of MSM in Abidjan from October 2011 to February 2012. Eligibility criteria included age ≥ 18 years and having had oral or anal sex with another man in the last 12 months. Weighted data analysis was conducted with RDSAT and SAS. We enrolled 603 participants, of whom 601 (99.7%) completed the questionnaire and 581 (96.7%) consented to HIV testing. HIV population prevalence was estimated as 18.0% (95% CI: 13.0-23.1); 86.4% (95% CI: 75.1-94.9) of HIV-positive MSM were unaware of their serostatus. In multivariable analysis, adjusting for age, education, and income, HIV infection was associated with unprotected sex at last sex with a woman, more than two male anal sex partners in last 12 months, inconsistent condom use during anal sex with a man, self-perceived risk of HIV, history of forced sex, history of physical abuse due to MSM status, and not receiving last HIV test result prior to study. HIV prevalence among MSM in Abidjan is more than four times as high as that of general population men. MSM engage in high-risk sexual behavior and most HIV-positive MSM are unaware of their serostatus. Greater access to HIV prevention, care, and treatment services targeted to MSM is necessary.
确定科特迪瓦阿比让男男性行为者（MSM）中的艾滋病毒流行率及相关风险因素。我们于2011年10月至2012年2月在阿比让对男男性行为者开展了一项横断面反应性抽样调查（RDS）。纳入标准包括年龄≥18岁且在过去12个月内与另一名男性有过口交或肛交。采用RDSAT和SAS软件进行加权数据分析。我们招募了603名参与者，其中601名（99.7%）完成了问卷调查，581名（96.7%）同意接受艾滋病毒检测。估计艾滋病毒人群流行率为18.0%（95%置信区间：13.0 - 23.1）；86.4%（95%置信区间：75.1 - 94.9）的艾滋病毒阳性男男性行为者不知道自己的血清学状态。在多变量分析中，校正年龄、教育程度和收入后，艾滋病毒感染与上次与女性发生性行为时无保护措施、过去12个月内有两个以上男性肛交性伴侣、与男性肛交时避孕套使用不一致、自我感知的艾滋病毒感染风险、强迫性行为史、因男男性行为身份遭受身体虐待史以及在研究前未收到上次艾滋病毒检测结果有关。阿比让男男性行为者中的艾滋病毒流行率是普通男性人群的四倍多。男男性行为者存在高危性行为，且大多数艾滋病毒阳性男男性行为者不知道自己的血清学状态。有必要为男男性行为者提供更多的艾滋病毒预防、护理和治疗服务。
