ABSTRACT
Objective To assess the prevalence of HIV infection and related factors in men who have sex with men (MSM) living for ≤5 years in Wenzhou of Zhejiang province.Methods MSM who were aged ≥ 16 years,had lived in Wenzhou for ≥3 months and had anal sex and/or oral sex with men in the last 12 months were recruited through respondent-driven sampling (RDS) from February to October in 2015.The MSM recruited completed a questionnaire for the information collection on socio-demographic characteristics,sexual behavior,awareness of HIV and related intervention,mental health status.Blood samples were collected from them for serological detection of HIV and syphilis antibodies.Software SPSS 18.0 was used to analyze HIV infection and related factors.Results A total of 454 MSM were investigated,108 of them (23.7％) were HIV positive.There were 267 MSM who lived in Wenzhou for ≤5 years,and 73 of them (27.3％) were HIV positive.Most of them were workers and commercial servants aged ≥ 25 years with personal monthly income ＜4 000 yuan and educational level of junior high school or below.According to multiple logistics regression analysis,age of 25-68 years old (OR=12.19,95％CI:2.29-65.02),heterosexual behavior in recent 6 months (OR=0.42,95％CI:0.18-0.96),believing it was possible to be infected with HIV (OR=0.06,95％CI:0.01-0.95),believing it was impossible to be infected with HIV (OR=0.03,95％CI:0.01-0.35) and syphilis status (OR=3.32,95％CI:1.05-10.52) were the risk factors associated with HIV infection.Conclusion Compared with MSM who lived in Wenzhou for ＞ 5 years,MSM who lived in Wenzhou for ≤ 5 years had higher HIV infection rate and higher prevalence of risk behavior.It is necessary to conduct targeted intervention among them.
