Meanwhile, 264 MSM were found to he positive for syphilis with the positive rate of 12.63%. Both HIV and syphilis posi rive rates varied significantly from 2006 to 2013 （χ2 = 30. 149, P〈0.05; χ2=92. 406, P〈0.05） . The survey also found that there were 86.36%, 26.60/oo and 6.04% of MSM who claimed of having homosexual, heterosexual and commercial sexual behaviors in recent 6 months with only 43.55%, 34.89% and 56.88% MSM admitting of condom use during each sexual intercourse.
