Syphilis infection among men who have sex with men in Hangzhou

Objective To understand the current status of syphilis infection among men who have sex with men （MSM） in Hangzhou. Methods A questionnaire survey was conducted among total 795 MSM from 2009 to 2012 in Hangzhou to collect data in terms of their soeio-demographics and risk behaviors. Blood samples were also collected for syphilis antibody test. Data were analyzed using SPSS 12.0 software, and chi square test was used for data statistical purpose. Results In Hangzhou, majority of MSM were young-aged, unmarried and well-educated. The survey revealed that 86.04% MSM had anal sex with men in the past six months. Only 29.97% MSM used condom for each anal intercourse, while 7.89% claimed that they never used con- doms. 228 MSM reported of having sex with female partners and 20.61% used condoms during each inter- course in the most recent 6 months. In total, 85 out of 785 MSM were infected with syphilis and the overall positive rate was 10.69%. The differences of annual prevalence from 2009 to 2012 were not significant, how- ever, the positive rates were significantly different among MSM with different education levels, marriage sta- tus and condom use （χ^2 =12. 232, 12. 630, 10. 150, P〈0.01）. The positive rate of HIV antibody was also higher among MSM with syphilis （72 =14. 565, P〈0.01）. Conclusions MSM was at high risk of syphilis infection mostly due to unprotected sex behaviors. Comprehensive health education and behavior intervention should he strengthened among MSM.
