High risk behavior and syphilis/HIV infection among men who have sex with men and women in Shenzhen

Objective To investigate the characteristics of high risk behavior and syphilis/HIV prevalence among men who have sex with men and women(MSMW)in Shenzhen. Methods Surveillance data from 2009 to 2011 among MSM in Shenzhen were collected and analyzed. Results Totally 809(27.49%)reported having had sex with men and women in the last 6 months among 2 943 MSM from 2009 to 2011. The infection rates of syphilis,HIV and syphilis-HIV co-infection among them were 17.80%,7.05% and 3.83%,respectively. Compared to MSM without female partners during the past 6 months,the proportions of the number of female partners more than 5,the number of male anal sex partners more than 2, inconsistent condom use with female partners,and condom use with male anal sex partners every time were higher. The proportions of inconsistent condom use with oral sex partners and syphilis/HIV infection rate of MSMW were lower. Conclusions MSMW have a lower proportion of consistent condom use with female partners. The risk of MSMW as a bridge transmitted AIDS/STD from MSM to general population cannot be underestimated.
