摘要:
了解泰安市大中专院校大学生男男性行为者(men sho have sex with men,MSM)的艾滋病病毒(HIV)感染状况及其相关危险行为,为制定适宜的健康干预措施提供依据.方法 采用横断面调查研究,对泰安市大中专院校在校MSM人群通过自愿咨询检测(VCT)的方式获得方便样本,采用自填式问卷调查收集人口学特征和行为学信息,并采集血液样本进行HIV、梅毒和单纯疱疹病毒Ⅱ型(HSV-Ⅱ)的血清学检测.结果 共有127例男男性行为者参与研究.性行为角色以“肛交性行为的被插入方”为主的占42.5%.最常用的寻找性伴的方式是网络(89.0%),其中69人通过男同交友软件Blued,占54.3%.有79.4%的被试存在多性伴,近6个月与固定性伴、临时性伴发生无保护肛交的比例分别为60.4%(55/91),50.7%(37/73).最近一次肛交的安全套使用率仅为61.4%,未使用安全套的原因主要是认为和性伴彼此忠诚(18.4%)、身边没有(18.4%)、认为自己不会感染HIV(16.3%).大学生艾滋病知识知晓率为96.1%,但8题全部答对的比例仅为58.3%.大学生HIV感染率为3.1%,4.7%曾感染过梅毒,HSV-Ⅱ血清阳性率为3.1%.单因素分析显示,主要性行为方式以“肛交性行为的插入方”角色为主、使用Blued软件作为寻找性伴的主要方式、与固定性伴发生无保护性行为是HIV感染的危险因素,但Logistic回归分析均无统计学意义.结论 泰安市大中专院校学生MSM艾滋病流行已经显现.急需采取针对性措施提高感染风险意识,改变普遍存在的高危性行为.
Abstract:
Objective To determine the prevalence of HIV and risky sexual behaviors among male college students who have sex with men in Taian.Methods A cross-sectional survey was conducted among MSM college students recruited by respondent-driven sampling (RDS) and voluntary counseling and testing (VCT).Self-administered questionnaires were used to collect social demographic characteristics and HIV/AIDS related risk sexual behaviors.Blood sample was collected to HIV,syphilis and HSV-11 testing.Results A total of 127 MSM students were recruited,63% of them self-identified gay,and 42.5% as female role in the sexual behavior.The most common way to find male sexual partner was the network,especially one of the software "Blued" through which 69 (54.3%) MSM students were recruited.About 79.4% of respondents had more than one male sexual partners.The proportion of unprotected anal intercourse (UAI) was 60.4% (55/91) with regular sex partners and 50.7% (37/73) with casual sex partners,respectively.The rate of condom use in their last homosexual anal intercourse experience was 61.4%,the main reasons for not using condoms included mutual loyalty (18.4%),having no condom at the time (18.4%),and low risk of infection (16.3%).The awareness rate of HIV/AIDS was 96.1%.The prevalence of HIV,syphilis and HSV-Ⅱ was 3.1%,4.7% and 3.1%,respectively.Univariate analysis showed that main sexual role as female,looking for male sexual partners using software "Blued",not using condoms with regular sexual partners were risk factors for HIV infection.Conclusion The HIV/AIDS epidemic has emerged among MSM students in Taian.Comprehensive intervention strategies that address condom promotion and health education need to be tailored to this vulnerable population to prevent HIV infection.
