目的了解深圳地区男男性行为人群(MSM)性伴数量,分析其影响因素。方法应用同伴推动抽样(RDS)法进行抽样调查,收集MSM人群人口学和性伴数等资料。用SAS软件对数据进行Poisson回归分析。结果共抽样调查351例MSM。最近半年,仅31.4%MSM没有肛交性伴或保持单一性伴,25.9%没有口交性伴或保持单一性伴:28.5%有女性性伴,其中11.4%有多个女性性伴。职业为娱乐场所从业人员和曾做过男男性工作者(MB),是MSM肛交性伴数和口交性伴数的共同危险因素。除此之外,HIV风险感知越高,艾滋病知识得分越高,MSM口交性伴数越多。结论对该人群有针对性的干预行动已刻不容缓,以有效阻断HIV传播和蔓延。
