: To identify social and behavioral characteristics associated with sexual risk behaviors among male sex workers who sell sex to men in Mombasa, Kenya.
: Using time-location sampling, 425 men who had recently sold, and were currently willing to sell sex to men were invited to participate in a cross-sectional survey. A structured questionnaire was administered using handheld computers. Factors associated with self-reported unprotected anal sex with male clients in the past 30 days were identified and subjected to multivariate analysis.
: Thirty-five percent of respondents did not know HIV can be transmitted via anal sex, which was a significant predictor of unprotected anal sex [adjusted odds ratio (AOR) 1.92; 95% confidence interval (95% CI), 1.16-3.16]. Other associated factors included drinking alcohol 3 or more days per week (AOR, 1.63; 95% CI, 1.05-2.54), self-report of burning urination within the past 12 months (AOR, 2.07; 95% CI, 1.14-3.76), and having never been counseled or tested for HIV (AOR, 1.66; 95% CI, 1.07-2.57). Only 21.2% of respondents correctly knew that a water-based lubricant should be used with latex condoms.
: Male sex workers who sell sex to men in Mombasa are in acute need of targeted prevention information on anal HIV and STI transmission, consistent condom use, and correct lubrication use with latex condoms. HIV programs in Africa need to consider and develop specific prevention strategies to reach this vulnerable population.
确定肯尼亚蒙巴萨向男性出售性服务的男男性工作者中与性风险行为相关的社会和行为特征。
采用时间-地点抽样法，邀请425名近期有过且目前愿意向男性出售性服务的男性参与横断面调查。使用手持电脑进行结构化问卷调查。确定过去30天内与男性客户进行无保护肛交的自我报告相关因素，并进行多变量分析。
35%的受访者不知道艾滋病毒可通过肛交传播，这是无保护肛交的一个重要预测因素[调整后的优势比（AOR）为1.92；95%置信区间（95%CI）为1.16-3.16]。其他相关因素包括每周饮酒3天或更多天（AOR为1.63；95%CI为1.05-2.54）、在过去12个月内自我报告有尿痛（AOR为2.07；95%CI为1.14-3.76）以及从未接受过艾滋病毒咨询或检测（AOR为1.66；95%CI为1.07-2.57）。只有21.2%的受访者正确知道应使用水性润滑剂搭配乳胶避孕套。
在蒙巴萨向男性出售性服务的男男性工作者迫切需要关于肛门艾滋病毒和性传播感染传播、持续使用避孕套以及正确使用乳胶避孕套润滑剂的针对性预防信息。非洲的艾滋病毒项目需要考虑并制定针对这一脆弱人群的具体预防策略。
