Effects of unsafe sexual behavior and sexual orientation on previous HIV testing and HIV testing willingness among college students in Harbin

Objective To analyze the effects of unsafe sexual behavior and sexual orientation on previous HIV testing and HIV testing willingness among college students in Harbin,to provide a theoretical basis for promoting and promoting HIV testing among them.Methods A cross-sectional survey design was used to place the automatic vending machine of HIV urine test kit in 9 universities in Harbin from December 2017 to January 2018.The questionnaire star was used to design and recruit college students to carry out an anonymous online survey.The estimated sample size was 6659.A multivariate logistic regression model was used to analyze the effects of unsafe sexual behavior and sexual orientation on previous HIV testing and HIV testing willingness among college students.WPS 2016 was used to sort out the database,and SPSS 21.0 software was used for statistical analysis.Results A total of 60849 valid questionnaires were collected.19.1%(11189/58605)of college students reported having sex.College students who used condoms correctly every time,occasionally or never during sex in the past six months 58.5%(6206/10603),25.2%(2669/10603)and 16.3%(1728/10603),respectively.Heterosexuality,homosexuality and bisexuality accounted for 94.1%(54393/57823),2.4%(1369/57823)and 3.5%(2061/57823),respectively.The HIV testing willingness of college students was 73.3%(44572/60849).The proportion of previous HIV testing was 10.3%(951/9241).Results of the multivariate logistic analysis showed that compared with the college students who used condoms correctly whenever they had sex in the past six months,there was no significant difference in the proportion of previous HIV testing among college students who sometimes/occasionally used or never used condoms(OR=0.94,95%CI:0.69-1.29;OR=1.11,95%CI:0.73-1.67),but their willingness to HIV testing was lower(OR=0.79,95%CI:0.71-0.89;OR=0.48,95%CI:0.42-0.55);Compared with heterosexual college students,homosexual or bisexual college students have a higher proportion of previous HIV testing(OR=2.62,95%CI:1.62-4.24;OR=2.04,95%CI:1.25-3.32),but have lower HIV testing willingness(OR=0.76,95%CI:0.62-0.93;OR=0.64,95%CI:0.53-0.77).Conclusions Unsafe sexual behavior existed among college students in Harbin,and college students with weak awareness of HIV prevention also have weak awareness of testing.Behavioral intervention should be strengthened and HIV testing promoted.Compared with heterosexuals,homosexual or bisexual college students had a higher proportion of previous HIV testing,but their willingness to test was lower.The HIV detection mode with better concealment,accuracy,and convenience should be promoted on the college's campus.
