To investigate the epidemic of HIV, HCV and syphilis, HIV-1 subtype among men who have sex with men (MSM) and to measure factors that correlated with sexual transmitted infections (STIs), a cross-sectional survey was conducted among 657 MSM in Zhenjiang, Jiangsu, during 2012-2013. Social-demographic characterization and risky behaviors were collected and blood samples were obtained. In this survey, the prevalence of STIs of HIV (5.3%), HCV (0.6%) and syphilis (19.2%) were measured. Of 35 HIV-infected MSM, 1 (0.2%) and 17 (2.6%) were co-infected with HCV and syphilis. Among 33 samples with available HIV-1 genomic fragments sequences, 6.1% B, 72.7% CRF01_AE and 21.2% CRF07_BC were indentified. Multivariate logistic regression analysis showed that age>30 years (OR 2.002; 95% CI 1.144 to 3.502) and having had STIs symptoms in the past year (OR 11.673; 95% CI 3.092 to 44.078) were positively correlated with STIs positive, while consistently use condom when have sex with male partners (OR 0.621; 95% CI 0.408 to 0.945) was significantly associated with a low STIs rate. The worsening epidemic of HIV, HCV and syphilis, complex subtypes of HIV-1 and risk factors suggest that effective intervention strategies should be strengthened for MSM in Zhenjiang, Jiangsu.
