Objective：To investigate the situation of HIV/Syphilis infection and its risk factors among men who have sex with men（MSM） in Jiangmen, providing evidence for AIDS prevention and control. Methods： Using the sentinel surveillance data of HIV/AIDS in MSM for analysis. Results： Among the 1 916 MSMs, the awareness of AIDS-related knowledge was 90. 19%, 6.73% were positive for HIV antibody, 4. 07% were positive for TPPA and PRP of syphilis, and 51.93% used condoms occasionally during homosexual and intercourses in recent 6 months. The multivariate logistic regression analysis showed that married and lived together（ OR = 1. 408, 95% CI 1. 153 ~ 1. 720） with commercial behavior in recent 6 months （ OR = 2. 458, 95 % CI 1. 266 - 3. 787 ） and syphilis infection（ OR = 5. 804, 95% CI 3. 196 - 10. 540） were significantly associated with HIV seroconversion. Drug use （ OR = 1. 164, 95% CI 1. 037 - 3. 722 ） and anal sex with same-sex sexual behavior in recent 6 months（ OR = 10. 753,95% CI 7.958 ~ 12. 685） were signif- icantly associated with syphilis seroconversion, while the history of non-syphilis STD in the recent years was a protective factor of syphilis infection（ OR = 0. 239, 95% CI O. 090 -0. 629）. Conclusion ： The morbidity of HIV and Syphilis is very high in MSM population in Jiangmen. The infec- tion of syphilis, married and lived together or with commercial behavior can increase the risk of HIV incidence. Drug use and anal sex with same-sex sexual behavior can increase the risk of Syphilis incidence.
