Characteristics Of Sexual Behavior Among HIV-infected Male Students In Nanjing

ObjectivesIn recent years,the global number of new HIV infections and AIDS-related deaths continues to decline annually,while the total number of HIV infected people,especially MSM(Men Who have Sex with Men,MSM)continues to rise.Young students are sexually active;however,HIV/AIDS preventive methods are quite weak.Therefore,the main objectives of this study are: a)To explore the molecular epidemiological characteristics of HIV-1 and the transmission networks among MSM college students in Nanjing b)To investigate the growth environmental factors influencing sexual orientation.C)To assess and compare the high-risk sexual behaviors between HIV positive MSM college students and HIV negative MSM college students.This combination of analyses can further help create comprehensive and coordinated strategies for prevention and control.Methods1.Questionnaire: recruitment of 201 college male students newly diagnosed with HIV in 2015-2019.Questionnaires were used to collect information regarding demographics,sexual behaviors,HIV/AIDS awareness and knowledge,sex education;random sampling of 794 male college students from two Universities in Nanjing.Questionnaires were also used to collect information regarding demographics,upbringing and sexual orientation.2.Using the Kinsey Scale developed in 1948 by Alfred Kinsey,794 male college students from the pilot universities were divided into two groups according to UNDP classification: heterosexual(non-sexual minorities)and non-heterosexual(sexual minorities).Kinsey scale score of 0 means heterosexual,and the remaining are non-heterosexual.3.Statistical Methods: Epidata 3.1 software,double dual data entry.Excel 15.30 software was used to build the original database,SPSS 21.0 statistical software was used for data analysis.Mean±standard deviation(±s)were used to describe the quantitative data.The percentage(%)was used to describe qualitative data or ranked data.Quantitative data was used to compare between groups using two independent samples t-test or one-way analysis of variance between groups or qualitative level data were compared using 2 test or Fisher’s exact test,test level for the α=0.05.To explore the acquired causes of sexual orientation college males,univariate and stepwise regression analysis were used.Results1.Epidemiological characteristics analysis showed that among the 201 HIV-infected MSM students,97.4% self-identify as non-heterosexual,and 95.5%(192/201)were infected with HIV through having sex with other men.(72.7%)major in engineering,art and economics,49.4% are sophomores and juniors.In terms of reason for testing,26.8% of students choose to get tested because of exposure of high-risk sexual behavior.2.Univariate analysis showed that parents’ marital status during childhood,type of main parental support,single-sex environment,upbringing,when raised as girl,sexual harassment,sexual assault,sexual abuse,serious setback in relationships,sex education and parents forbidding close opposite sex relationships will influence sexual orientation among male college students(P<0.1).Multiple stepwise regression analysis showed that being raised as a girl,experiencing opposite sex abuse,parents’ involvement in sex education,single-sex environment,upbringing and sexual harassment are acquired factors influencing non-heterosexual sexual orientation.3.The awareness rate of the HIV/AIDS core knowledge among the 201 HIV-positive MSM was only 81.5%;the average age they started to be attracted to the same sex is 16.4±2.9(6~24)years old,the average age of first sexual experience is 18.9±2.1(10~25)years old,the frequency of condom use is only 56.7%,.The proportion of regular and casual partners among uninfected male students is much higher than HIV-positive MSM Students(χ2= 445.565,P<0.001)and(χ2= 484.041,P<0.001).Conclusion1.Education on HIV/AIDS is not comprehensive,only part of the knowledge is taught.HIV/AIDS prevention and health education should start before college students start being sexually active.This will improve voluntary counseling and testing(VCT)knowledge,risk awareness in this population,increase utilization of VCT to reduce high-risk sexual behavior.2.Childhood experience of sexual harassment,sexual abuse by the opposite sex and other factors affect sexual orientation of college males.Parents should provide a good environment for their children.Once the child has experienced traumatic life experiences,parents and schools should provide psychological counseling as soon as possible to reduce the negative impact of postnatal environment on sexual orientation formation.3.College students have a poor understanding of the AIDS epidemic in Chinese universities,and only a few have a high degree of knowledge.The status of MSM AIDS-related "KAP" in colleges and universities is not optimistic.Solidly carrying out anti-AIDS publicity work in colleges and universities,popularizing anti-AIDS knowledge,enhancing students’ awareness of anti-AIDS,and effectively improving condom use rate are still the center of the current anti-AIDS work in colleges and universities.Mobile Phone APPs have become the main tools for communication among MSM students to contact sexual partners.Therefore,this technology should play a significant role in the control of HIV/AIDS.
