Abstract：Objective To investigate the status of recent HIV infection and its related risk factors among men who have sex with men (MSM) in Urumqi City, and to provide a scientific basis for estimating the epidemic tendency of HIV/AIDS and assessing the epidemic situation and high-risk behavior intervention. Methods A total of 866 MSM were recruited from HIV/AIDS sentinel surveillance in Urumqi City in 2015, and their serum samples were tested by using ELISA. The HIV-antibody positive samples in primary screening were confirmed with Western blot. All HIV-antibody positive samples were further tested with BED-capture enzyme immunoassay (CEIA) to find recent HIV-1 infection, and then the recent HIV infection rate among the MSM in 2015 was estimated. A questionnaire survey was conducted to investigate the risk factors of HIV infection among the MSM. Results A total of 866 MSM were surveyed, and the mean age was (31.03±7.44) years old, of which the Han, Uyghur, Hui and other ethnic groups accounted for 84.76%(n=734), 6.24% (n=54), 6.24% (n=54), and 2.76%(n=24) respectively. 83.60% of the MSM had received college or higher education. The awareness rate of knowledge concerning HIV/AIDS prevention and treatment was 97.92%. 95.84% (830/866) had anal sex with men in the last 6 months, and the ratio of consistent condom use was 52.04% (432/830). The HIV-positive detection rate was 5.31% (46/866), including 7 cases with previous infection. The results of BED-CEIA indicated that there were 14 cases of long-term HIV infection and 25 cases of recent HIV infection. The annual recent infection rate calculating by McDougal was 5.95% (95%CI:4.37%-7.52%). Multivariate logistic regression analysis showed that the age of ≥45 years (OR=3.105), consistent condom use during homosexual behavior in the last 6 months (OR=0.205) and having knowledge concerning HIV/AIDS prevention and treatment (OR=0.151) were the independent factors influencing newly-diagnosed HIV infection in the MSM. Conclusions The recent HIV infection rate in the MSM in Urumqi City in 2015 was high. It is necessary to continuously strengthen the intervention and pay special attention to the elder among the MSM.
