2020年北京市男男性行为者自我评价感染艾滋病风险影响因素分析

Analysis on self-assessed risk of HIV infection and its influencing factors in men who have sex with men in Beijing,2020

目的了解男男性行为者(men who have sex with men,MSM)自我评价感染艾滋病风险的情况及其影响因素。方法2020年5-9月采用同伴推动抽样法招募MSM进行横断面问卷调查和人类免疫缺陷病毒(human immunodeficiency virus,HIV)抗体检测,采用SPSS 19.0软件进行单因素和多因素分析。结果共调查424名MSM,平均年龄为(41.8±11.1)岁,22.88%的MSM自我评价感染艾滋病的风险高,77.12%认为风险低,多因素Logistic回归分析结果显示,最近6个月同性肛交临时性伴数>1(OR=1.694,95%CI:1.055~2.718)、最近6个月与男性发生过肛交性行为(OR=4.691,95%CI:1.057~20.812)、最近一年患过性病(OR=2.069,95%CI:1.144~3.743)者自我评价感染艾滋病风险高。结论北京市MSM人群自我评价感染艾滋病风险意识较差,MSM自我评价感染艾滋病风险与最近6个月同性肛交临时性伴个数、最近6个月是否与男性发生肛交性行为以及最近一年是否患过性病有关,但与是否使用安全套无关。
