广西男男性行为者向性伴告知HIV感染状况与知晓性伴感染状况的影响因素分析

Influencing factors of notification among MSM and their awareness of sexual partners'HIV infection status Guangxi

目的 了解广西MSM向性伴告知HIV感染状况(简称感染状况)与知晓性伴感染状况的现状,分析其影响因素。方法 2021年9月至2022年2月在广西5个城市采用方便抽样的方法招募MSM,并对其进行一对一面对面匿名调查,采用χ^(2)检验和Logistic回归模型分析MSM向性伴告知感染状况与知晓性伴感染状况的影响因素。结果共调查317名MSM,50.5%的MSM向性伴告知了感染状况,41.0%的MSM知晓性伴的感染状况。多因素Logistic回归分析显示,最近6个月有临时性伴(OR=0.083,95%CI:0.044~0.157)和赞成每次性行为均使用安全套(OR=0.343,95%CI:0.191~0.617)的MSM向性伴告知感染状况的可能性更低;有医疗保险(OR=1.483,95%CI:1.552~12.498)、最近6个月患HIV感染和梅毒以外的性病(OR=43.016,95%CI:4.602~402.060)的MSM知晓性伴感染状况的可能性更高;通过网络寻找性伴(OR=0.282,95%CI:0.081~0.984)、男性性伴数2~5个(OR=0.415,95%CI:0.201~0.856)、赞成每次性行为均使用安全套(OR=0.439,95%CI:0.229~0.841)和最近6个月有临时性伴(OR=0.126,95%CI:0.060~0.264)的MSM知晓性伴感染状况的可能性更低。结论 广西MSM向性伴告知感染状况及知晓性伴感染状况的比例偏低,仍需要加强MSM与性伴间相互了解感染状况的宣传教育,对通过网络途径寻找性伴、有2个及以上性伴和有临时性伴的MSM制订更具有针对性的干预策略,以促进MSM知情交友。

Objective To understand the situations of the notification among men who have sex with men(MSM)and their awareness of sexual partners'HIV infection status in Guangxi,and to analyze the related influencing factor.Methods From September 2021 to February 2022,convenient sampling was used to recruit MSM in 5 cities in Guangxi,and a"one-to-one""face-to-face"anonymous survey was carried out.Chi-square test and Logistic regression analysis were used to analyze the related factors influencing the notification of MSM and their awareness of sexual partners'HIV infection status.Results Out of 317 MSMs enrolled in,50.5%notified sexual partners of their infection status,and 41.0%knew about the infection status of their sexual partners.Multivariate Logistic regression analysis showed that MSM who had a temporary partner in the last 6 months(OR=0.083,95%CI:0.044-0.157)and agreed to use condoms every time(OR=0.343,95%CI:0.191-0.617)were less likely to notify their sexual partners about the infection status.MSM with medical insurance(OR=1.483,95%CI:1.552-12.498),sexually transmitted diseases other than HIV and syphilis in the last six months(OR=43.016,95%CI:4.602-402.060)were more likely to know the infection status of their sexual partners.MSM who sought sexual partners via internet(OR=0.282,95%CI:0.081-0.984),had 2-5 male sexual partners(OR=0.415,95%CI:0.201-0.856),agreed to use condoms every time(OR=0.439,95%CI:0.229-0.841),and had temporary partners in the last 6 months(OR=0.126,95%CI:0.060-0.264)were less likely to know the infection status of their sexual partners.Conclusions The proportion of MSM in Guangxi who inform sexual partners of the infection status and know the infection status of sexual partners is lower.It is still necessary to strengthen the publicity and education of mutual understanding of infection status between MSM and their sexual partners.To develop more targeted intervention strategies for MSM who seek sexual partners via internet,have two or more sexual partners and have temporary sexual partners,so as to promote informed dating among MSM.
