A special field survey to MSM was conducted. The MSMs surveyed are informed and agreed to attend this survey. Results There are 623 cases as the study samples. By quick evaluation and calculation, the incidence density is estimated to be 2.65/100 persons -year in 2013, 1.72/100 in 2014, the average observed persons-year is 3.37 ± 1.72 years. The age of having sex among MSM for the first time is about 20 years old. A third of those had first sexual behavior among MSM when 12 to 18 years old; The usage rates of condoms when having the latest sexual behavior with the fixed, temporary and commercial same-sex sexual partner are 55.27% (304/550), 54.55% (300/550), 82.35% (28/34); the usage rates of condoms for every sexual behavior with the fixed and temporary same-sex sexual partner in the past six months are 46.18% (254/550), 46.18% (223/550); According to the multi-variable logistic regression model, the frequency of the use of condoms when having anal sex with same sex (OR = 0.404, 95% CI 0.226 to 0.724), and whether same sex having commercial sexual behavior (OR = 2.466, 95% CI 2.466 to 2.466) are statistically related with HIV infection. Conclusion The quick evaluation results show that AIDS infections among MSM group with single marital status between 18-29 years old in Tianjin in the past two years is quite stable, but HIV infection risk still exists for this group.
