摘要: 目的 了解男男性行为人群(men who have sex with men,MSM)最近1次接受艾滋病病毒(human immune deficiency virus ,HIV)检测时间距离及其影响因素。方法 2014年4~10月,以绵阳市辖区9县(市、区)MSM为对象,在固定场所知情同意下,应用滚雪球抽样法,进行调查对象招募和自填式匿名行为学调查和血清学检测。结果 共调查1 097例,76.7%近1年做过HIV检测,75.8%做过检测并知道检测结果。最近1次检测时间距离≤3个月、4~6个月、7~12个月、>12个月分别依次为34.3%、28.9%、24.2%、12.6%,HIV确证感染率分别依次为0.4%、3.8%、2.0%、8.8%,差异有统计学意义(P<0.001)。多因素分析发现,年龄、性取向、接受预防服务、寻找性伴场所、近1周肛交次数、近1次肛交保护性、近6月肛交保护性是HIV检测时间距离的独立影响因素(均有P<0.05)。结论 MSM HIV检测时间距离较短,促进感染者及时发现。检测时间距离与人口学特征、预防服务和性行为相关。Abstract: Objective To understand the time interval of the last time of the human immunodeficiency virus(HIV)testing and the influencing factors among men who have sex with men(MSM).
