| BackgroundAIDS is a severe infection across the world and a serious threat to human health. At present, the global AIDS epidemic is controlled basicly. Chinese AIDS epidemic is rising, but rising is in slowdown, and epidemic is moving from high-risk groups to the general population-proliferation. The relationship between Syphilis and AIDS are very close, so we should pay attention to strengthen the control of Syphilis outbreak in AIDS prevention and control work.System researches about AIDS knowledge, behavioral factors among MSTDs in Changchun were less in the past. Therefore, it is significant to do research on the epidemic situation of AIDS/STDs as well as AIDS knowledge and behaviors.ObjectiveInvestigating the infectious status and risk factors of AIDS and Syphilis for MSTDs in Changchun, analyzes related factors in order to provide scientific basis for changing high-risk behaviors among MSTDs and halting AIDS/STDs disease outbreak.MethodsApril to June in 2010, a cross-sectional survey was conducted on 800 MSTDs in Changchun, using questionnaire survey method, and gathering venous blood 5-10ml. The questionnaire included demographic information, serological information, behavioral information, STDs infections, AIDS prevention relevant information. Survey results were input into AIDS Sentinel Surveillance Network and the data were analyzed via SPSS 13.0 statistical software. Measurement data were expressed as mean, standard deviation, median index, and numeration data were expressed as rate and proportion. Chisquare test was applied for the comparison between groups classification variables. Logistic regression model was used to analyze the associated factors of AIDS and Syphilis infection. AIDS knowledge awareness, high-risk behaviors, STDs diagnosis and HIV testing.Results1. In this survey, the average age of MSTDs in Changchun was 27.4±6.9. Married crowd accounted for 54.1%. Registered population of Jilin province and the Han Chinese patients was 94.0% and 96.1% respectively. Age, marital status, household register and nationality distribution had significant difference between the two sources of MSTDs.2. The general awareness rate of AIDS knowledge of MSTDs was 91.0%. The awareness rate of three transmission ways about AIDS was 100%. and part of MSTDs had a certain lack of understanding about some non-transmission of HIV.3. The incidence of commercial sex and temporary sex among MSTDs in recently three months was 34.4% and 36.2% respectively. The incidence rate of injecting drug use and homosexual sex was 0.8% and 5.2% respectively. Living alone was the risk for high-risk behavior occurrence, and whether to accept AIDS peer education in recent one year was the protective factors for high-risk behavior occurrence.4.21.8% of the MSTDs had been diagnosed STDs in recent one year, and Syphilis had the largest proportion. Living alone and homosexual sex were the risk factors for STDs infection before. Coverage of HIV prevention interventions for MSTDs was 91.3%.5.61.6% of the MSTDs had been conducted an HIV antibody test in recent one year. Sample sources, household register, diagnosis of STDs last year and AIDS intervention were the influence factors of HIV testing.6. The infection rate of HIV and Syphilis of MSTDs was 0.4% and 2.1% respectively. The HIV infection possibility of MSTDs who aged≤20 years old more than the ones who aged> 20 years old.Conclusion1. In this survey, the 800 MSTDs are mainly concentrated in sexual activity crowd, the proportion in marriage is large, floating population is less.2. The general awareness rate of AIDS knowledge of MSTDs in Changchun is high. three ways of transmission are all known, there is a certain lack of understanding of non-transmission of HIV.3. This investigation shows that the infection rate of AIDS and Syphilis of MSTDs is 0.4% and 2.1% respectively, and the trend is in a low prevalence overall. The rate of HIV infection in young people is high.4. The survey shows that the incidence rate of high-risk behaviors of MSTDs is 51.5%. living alone was the risk for high-risk behavior occurrence, and whether to accept AIDS peer education in recent one year was the protective factors for high-risk behavior occurrence.21.8% of MSTDs has been diagnosed STDs in recent one year. living alone and homosexual sex are the risk factors of STDs infection before.61.6% of MSTDs have been conducted an HIV antibody test in recent one year. The STD specialist out-patient, non-local census register, diagnosed of STDs and received AIDS interventions last year were the risk factors of HIV testing.
