男男性行为者对性伴HIV血清学状态知晓情况及其安全性行为的调查

HIV serostatus awareness of sexual partners and safe sex behaviors among Chinese men who have sex with men

目的了解男男性行为者(MSM)对不同类型性伴艾滋病病毒(HIV)血清学状态的知晓情况及其影响因素;分析MSM对性伴HIV血清学状态的知晓情况与安全性行为的关系。方法自2018年4-6月,通过网络问卷的形式对湖南省MSM进行调查。结果共调查232名MSM,年龄为(29.0±8.2)岁,对固定性伴、临时性伴和商业性伴的HIV血清学状态的知晓率分别为36.1%(60/166)、7.0%(9/129)和0(0/8),差异有统计学意义(χ^(2)=39.747,P=0.000);与固定性伴、临时性伴和商业性伴发生性行为时的安全套持续使用率分别为44.2%(65/147)、55.2%(64/116)和20.0%(1/5),差异无统计学意义(χ^(2)=4.611,P=0.112);多因素分析显示,与同性性伴居住是影响MSM对性伴HIV血清学状态知晓率的主要因素[比值比(OR)=2.5,P=0.000,95%可信区间(CI):5.0~122.2];MSM对性伴HIV血清学状态是否知晓与其安全性行为未见明显统计学差异(固定性伴:χ^(2)=0.151,P=0.698;临时性伴:χ^(2)=0.454,P=0.503)。结论MSM对不同类型性伴的HIV血清学状态知晓率不同,与不同类型性伴的安全套使用率均较低,是否知晓其性伴HIV血清学状态与安全性行为无统计学相关性。因此,探讨如何提高MSM的安全套持续使用率是我国艾滋病防治工作的根本任务。

Objective To investigate the HIV serostatus awareness of different types of sexual partners and the associated factors among men who have sex with men(MSM),and to explore the relationship between the HIV serological status awareness of sexual partners and their safe sex behaviors.Methods From April to June 2018,232 MSM in Hunan province were investigated by online questionnaire.Chi-square test and logistic regression model were used to analyze the data.Results The age of the respondents was 29.0±8.2 years,and the HIV awareness rate of regular partners,casual partners and commercial partners was 36.1%,7.0%and 0,respectively(χ^(2)=39.747,P=0.000).The rate of consistent condom use in sex with regular partners,casual partners and commercial partners was 44.2%,55.2%and 20%,respectively(χ^(2)=4.611,P=0.112).The results of multiple logistic regression showed that living with the same-sex partners was the main factor affecting HIV status awareness of sexual partners among MSM(OR=2.5,P=0.000,95%CI:5.0-122.2).However,there was no significant statistical difference between the awareness of infection status of sexual partners with HIV and their safe sexual behaviors(regular partners:χ^(2)=0.151,P=0.698;casual partners:χ^(2)=0.454,P=0.503).Conclusion The HIV status awareness of different types of sexual partners among MSM is different,and the rates of consistent condom use with different types of sexual partners are all low.In addition,whether MSM are aware of their sexual partners’infection status and consistent condom use is not statistically correlated with safe sex.Therefore,AIDS prevention interventions should focus on how to improve consistent condom use among MSM rather than HIV serostatus disclosure.
