目的 了解绵阳市男男性行为者(men who have sex with men, MSM)获取艾滋病防治信息途径(简称“防治信息”)的意愿现状,分析关联因素。方法 2018年2-10月采用滚雪球抽样法,对四川省绵阳市MSM进行获取防治信息意愿、性行为学等调查和血清学检测。获取防治信息意愿关联因素的单因素分析用χ2检验,多因素分析用logistic回归模型。结果 调查合格问卷1 126份,获取防治信息意愿主动型构成比为63.9%,MSM社区组织的艾滋病病毒(Human immunodeficiency virus,HIV)咨询检测构成比为51.9%、群体干预活动构成比为12.0%;被动型构成比为36.1%(朋友构成比为16.3%、互联网构成比为16.6%、其他构成比为3.3%)。HIV阳性率在被动型构成比为5.2%,高于主动型的2.8%(P=0.041)。多因素分析结果,婚姻状况在婚及其他(OR=2.240)、本地居住时间≥1年(OR=2.326)、社区朋友数≥5人(OR=1.739)、知晓艾滋病知识(OR=3.918)、近1年接受预防服务(OR=2.310)、安全感得分(OR=1.029)、浴室/公园/互联网寻找性伴(OR=2.201)、近6个月肛交有保护(OR=1.835)的以主动型获取防治信息的概率高,干部职员/其他职业(OR=0.558)、性角色均可方(OR=0.710)以主动型获取防治信息概率低。结论 绵阳市MSM获取防治信息意愿以主动型为主,其意愿与人口学特征和性行为相关,主动型其行为风险低于被动型,应不断强化被动型的行为干预。

Objective To understand the current willingness and the associated factors of men who have sex with men(MSM) to access the prevention and control information on AIDS(referred to as prevention and control information) in Mianyang City.Methods From February to October 2018,the snowball sampling method was used to survey the willingness to access the prevention and control information and sexual behavior, and the serological testing of MSM in Mianyang City, Sichuan Province.The univariate analysis of factors associated with willingness to access the prevention and control information was performed using the χ~2 test, and the multivariate analysis was conducted using the logistic regression model.Results There were 1 126 qualified questionnaires, with a 63.9% willingness to proactively obtain prevention and control information, 51.9% for HIV counseling and testing by MSM community organizations, and 12.0% for group intervention activities.The passive component was 36.1%(16.3% for friends, 16.6% for the internet, and 3.3% for others).The HIV-positive rate was 5.2% in the passive type, which was higher than 2.8% in the active type(P=0.041).In the multivariate analysis, marital status in marriage and others(OR=2.240),local residence time≥1 year(OR=2.326),number of friends in the community≥5 people(OR=1.739),knowledge of AIDS(OR=3.918),receipt of prevention services in the past year(OR=2.310),feeling safe scores(OR=1.029),finding sexual partners in bathroom/park/internet(OR=2.201),and anal sex protected in the past 6 months(OR=1.835) had a high probability of proactive access the prevention and control information, while staff/other occupations(OR=0.558),and bisexual roles(OR=0.710) had a low probability of proactive access the prevention and control information.Conclusion MSM in Mianyang City is mainly active in willingness to obtain prevention and control information.The willingness is related to demographic characteristics and sexual behavior.The proactive type has lower behavioral risk than the passive type, and the behavioral interventions for the passive type should be continuously reinforced.
