摘要
目的了解东莞市男男性行为人群(MSM)的高危行为特征,艾滋病病毒(HIV)感染情况及影响因素,为在该人群中开展防控措施提供依据。方法利用2010-2012年东莞市MSM哨点监测数据,对MSM的人口学特征、行为学特征、性病症状、接受干预服务、HIV和梅毒感染水平等进行分析。结果共调查MSM 984人,平均年龄为(30.36±6.71)岁;最近6个月发生过同性、异性性行为的比例分别为73.37%和37.5%,与同性、异性发生性行为时坚持使用安全套的比例分别为48.89%和29.27%。近1年有性病相关症状的MSM的比例为6.81%,接受过干预服务的比例为59.04%。HIV和梅毒抗体阳性率分别为14.23%和15.35%,其中2010-2012年HIV阳性率分别为10.5%、11.33%和22.91%。多因素Logistic回归分析结果表明:艾滋病知识知晓和接受过干预服务与最近6个月同性性行为时坚持使用安全套的关系有统计学意义(P<0.05);梅毒抗体阳性、近1年有性病相关症状、年龄在≥40岁、样本来源等因素,与HIV感染的关系有统计学意义(P<0.05)。结论东莞市MSM的HIV感染率高,且上升趋势明显,迫切需要加强行为干预,防止艾滋病向一般人群蔓延。
