| Objectives:In this study,a non-government organization(NGOs)in Changchun City investigated the MSM population to determine the status of HIV and syphilis infection among the MSM population in the region,and analyzed the main influencing factors of HIV and syphilis infection in the MSM population in the region,aimed at giving full play to the advantages of NGOs actively,expand the coverage of HIV/AIDS high-risk behavioral interventions,and provide more effective suggestions for the prevention of HIV and syphilis infections among MSM populations,improve services,and improve treatment effectiveness.Methods:From December 2016 to December 2017,the study recruited men who have sex with men in Changchun City,Jilin Province,and conducted HIV and syphilis counseling tests and AIDS-related surveys.A total of 1736 MSM test subjects were recruited within 12 months.Among them,1699 were non-HIV positive and 1529 were non-syphilis positive.Questionnaire surveys were conducted to collect data on sociodemographic data,infection status of certain diseases,sexual behaviors,and knowledge of AIDS-related knowledge among MSM populations,and apply the HIV and syphilis antibody detection reagent to detect MSM populations.The data database was established using a third-party e-questionnaire application program,using IBM_SPSS24.0 statistical software package for data analysis,and the count data adoption rate and composition ratio to describe.New infections were expressed as a rate,and the chi-square test was used for comparison between groups,and multivariate Logistic regression was used to analyze the multivariate analysis of new HIV and syphilis infections.Result:1.Among the 1736 cases,the average age was 29.28±8.71 years,the minimum age was 15 years,and the maximum age was 80 years.The age group of 21-30 years old was the highest(59.1%),and the age group over 50 years old was the least(2.7%).A total of 1696 Han people were detected in the population,accounting for 97.7% of the total test population,58.9% of them were university students and above,36.8% were in junior high school and senior high school,and 75.7% of the marital status of the total test population was unmarried.The main place of residence was Changchun City(93.5).%),mostly freelancers(30.6%),followed by technical staff(20.7%)and students(19.1%),and there are relatively more bars(22.5%)in gathering places.Among the surveyed population,the largest number of self-identified homosexuals(64.2%),followed by self-identified bisexuals(31.9%);the MSM population had the most neutral role of 0.5,accounting for 49.5%,and the sexual role of 1 total of 30.4%.Only 2.1% of the MSM population had experience in drug use.Today,1.3% of drug users are drug users;Of the population,9.2% had a history of syphilis,4.3% had a history of condyloma acuminatum,and 27.0% had a history of hemorrhoids.In the course of sexual intercourse,48.3% used condoms every time,43.2% occasionally used condoms,and never used condoms with 8.5%.2.The subject’s cognition of HIV infection: 99.9% of survey respondents felt nervous when they referred to AIDS;96.6% of MSM people thought the topic of AIDS was very relevant to themselves;71.6% of the respondents did not know whether the person infected with HIV was Can be seen from the outside,only 21.5% felt that it could not be seen;99.8% did not know if there were any AIDS patients around.Among the problems that may occur with HIV infection,they all believe that infection with HIV-infected blood,children born to HIV infected women,and syringe sharing with HIV infected individuals will occur HIV infected.A total of 57.7% felt that having sex with only one sex partner could reduce the probability of HIV infection.66.8% of the MSM population never used aphrodisiacs,RUSH,No.0 capsules,etc.when they had sex,occasionally used 15.6%,14.5% tried,and only 3.2% often used.In addition,52.9% of the respondents had a need to further receive knowledge counseling services related to HIV and syphilis infection.3.Analysis of new HIV positive status in the test population: Among the 1,699 previously non-HIV positive subjects,the new HIV positive rate was 10.8%.In the comparison of HIV positive rate with demographic data and part of disease history and behavior,age groups,academic records,sexual behaviors,history of hemorrhoids,and use of condoms during sexual activity were statistically different from new HIV positive rates(p<0.05).There was no significant difference in nationality,marital status,sexual orientation,and drug use history from HIV positive rates(p>0.05).Multivariate Logistic regression model analysis showed that the use of condoms,age grouping,sexual behavior,and history of hemorrhoids in sexual behaviors had a statistically significant effect on the HIV positive status in the population tested by MSM.The specific manifestations were condom use occasionally in sexual behavior(OR=2.380,95% CI= 1.678-3.376),sexual condoms were not used(OR=1.833,95%CI=1.015-3.311),age group≥51 years old(OR=3.383,95%CI=1.528-7.490)and hemorrhoids detection population(OR=2.062,95%CI=1.474-2.884)had a higher prevalence of new HIV infection;while there was a lower incidence of new HIV infection in the sexual role in people with a role of 0.5(OR=0.579,95% CI=0.394-0.850)and those with a sex role of 1(OR=0.380,95%CI=0.238-0.607).Among the newly identified HIV-positive people,the mean value of CD4+ T cell counts was 415.75/μL,the minimum was 4/μL,and the highest was 1128/μL.Among them,the number of CD4+ T cell count ≤200/μL group was the lowest,with a total of 30,accounting for 16.4%,and the ≥501/μL group had the most,a total of 53,accounting for 29.0%.4.New syphilis positive investigation results: Among the 1529 previously non-syphilis positive investigators,the new syphilis positive rate was 8.7%.Comparison of positive new syphilis and demographic data,history of some diseases,and behaviors,use of condoms and new syphilis in age groups,education,marital status,history of hemorrhoids,and sexual behaviors There were statistically significant differences(p<0.05),but there was no significant difference in nationality,sexual orientation,sexual behaviors,and the history of drug use and new syphilis(p>0.05).Multivariate Logistic regression model analysis showed that age group and hemorrhoid history had a statistically significant effect on the incidence of new syphilis infection(p<0.05),and there was a higher rate of new syphilis infection among people aged ≥ 51 years old(OR = 7.637,95% CI = 3.111-18.747)and those with hemorrhoids(OR = 1.725,95% CI = 1.161-2.562).Conclusion:1.The positive rate of HIV and syphilis in the MSM population in Changchun City detected by a non-governmental organization was at a relatively high level;2.The MSM population has a good understanding of HIV infection-related problems and a low demand for HIV and syphilis infection-related counseling services after testing;3.Age ≥51 years old,with hemorrhoid history,occasionally using condoms and not using condoms are risk factors for new HIV infection in MSM population;4.Age ≥51 years old and history of hemorrhoids are risk factors for new syphilis infection in MSM population. |
