上海市浦东新区男男性行为者HIV定期检测状况调查

The cross-section study of HIV regular testing among men who have sex with men in Pudong district,Shanghai

目的了解上海市浦东新区MSM的HIV定期检测情况,为开展针对性干预提供科学依据。方法采用横断面调查方法,于2019年2-6月,通过艾滋病自愿咨询检测门诊、Blued交友软件、同伴教育员等多种方式招募研究对象。对研究对象开展问卷调查,收集信息主要包括HIV检测、交友软件使用、性行为发生情况等。采用Logistic回归模型对HIV定期检测行为(过去一年内HIV检测≥2次)进行分析。结果共计420例MSM纳入本研究,54.29%的研究对象年龄<30岁,42.62%为上海户籍,84.76%使用过Blued软件。研究显示MSM中HIV定期检测比例为59.05%(248/420)。Logistic回归模型多因素分析显示,经常使用和偶尔使用Blued软件(aOR=2.99,95%CI:1.41~6.33;aOR=2.56,95%CI:1.33~4.91),在VCT门诊检测HIV(aOR=3.97,95%CI:2.53~6.24),偶尔发生临时性行为(aOR=2.25,95%CI:1.33~3.81)和发生性行为前让性伴检测HIV(aOR=3.42,95%CI:2.07~5.66)与较高的HIV定期检测比例密切相关。结论上海市浦东新区仍有较大比例的MSM没有定期检测HIV,应进一步利用互联网平台等多种渠道和多种形式开展宣传教育,促进MSM建立定期接受HIV检测的健康意识,降低传播风险。

Objective To understand the regular HIV testing behavior among men who have sex with men(MSM)in Pudong district,Shanghai,aiming to provide scientific evidence for targeted interventions development.Method We conducted a cross-section survey among MSM recruited from February to June in 2019 through an AIDS voluntary counseling and testing clinic(VCT),Blued dating software,and peer educators.Data collected in the survey included HIV testing behaviors,the use of dating software,and the occurrence of sexual behavior.The logistic regression model was used to analyze the occurrence of regular HIV testing(defined as HIV testing more than two times in the past year)and its influencing factors.Result A total of 420 participants were included in the study.About 54.29%of study participants were younger than 30 years old,42.62%were locally from Shanghai,and 84.76%ever used Blued.The result showed that the proportion of MSM who had a regular HIV testing behavior was 59.05%(248/420).Multivariate Logistic regression model showed that behavioral factors associated with a higher rate of having regular HIV testing included often or occasionally using Blued software(aOR=2.99,95%CI:1.41-6.33;aOR=2.56,95%CI:1.33-4.91),having HIV testing in VCT clinic(aOR=3.97,95%CI:2.53-6.24),occasionally having temporary sexual behaviors(aOR=2.25,95%CI:1.33-3.81),and asking sexual partners to have HIV tested before having sex(aOR=3.42,95%CI:2.07-5.66).Conclusion MSM in Pudong district,Shanghai had a higher proportion of not having a regular HIV testing.Further efforts are needed to well use the internet as an effective intervention platform together with other intervention strategies to promote HIV education to increase the awareness of the importance of the HIV regular testing and to reduce the risk of HIV transmission.
