The MSM generalinformation, awareness of AIDS-related knowledge, and willingness of AIDS testingwere analyzed descriptively. Chi-square test used to compare differences betweengroups. Influencing factors were analyzed by logistic regression analysis.Results(1) Age of the first male sexual behavior among MSM ranged from11to60years old, and the average and median age were19.91±5.17and18, respectively. Thegender distribution of the first sexual behavior was that there were359men89.75%accounting for89.75%and41women accounting for10.25%.272respondents (68.00%) had1to3sexual partners,102respondents (25.50%) had4to5, and26respondents (6.50%) had above6.(2) Condom usage rate of last homosexual behavior, last commercial homosexualbehavior, and last heterosexual behavior among MSM were64.36%,72.73%and50.00%, respectively.(3) Of400respondents, the proportions of receiving peer education, publicityand distribution of condoms and AIDS counseling and testing, and HIV testing were52.5%,57.5%and61.5%, respectively.(4) The awareness rate of AIDS-related knowledge was85.50%. There weresignificant differences in the awareness rate among different ethnicity, sample sources,local residence time, feasibility of regular testing, and testing methods (P<0.05). Butthe awareness rate had no difference in marital status, household, and willingness ofinforming testing results (P>0.05).(5) The infection rates of HIV, syphilis and hepatitis C were11.00%,9.50%and0.00%among MSM in this survey, respectively. After being adjusted by mid-pointformula of McDougal calculation method, the new infection rate of HIV-1amongMSM of Qiqihar city in2014was10.69%.(6) The results of logistic regression analysis showed that age, knowledgeawareness, counseling and testing HIV regularly, sexual partners, age of firsthomosexual behavior, testing results of syphilis, condom usage of homosexualbehavior in recent6months, and location of sex were the influencing factors of HIVinfection (P<0.05), while marital status, educational levels, gender of first sex objects,sex orientation, and heterosexual behavior nearly6months were not (P>0.05).Conclusions(1) MSM of the local residents, low age, and high school or higher are in themajority in this survey.(2) The rate of condom use in MSM homosexual or heterosexual intercourse isonly24.31%and33.33%respectively in Qiqihar within recent half year, which needs to be improved.(3) The AIDS awareness rate in the group of MSM is85.50%.
