RESUMO
Objective@#To understand the current status of acquired immunodeficiency syndrome (AIDS) knowledge, attitudes, and practices of college students in Tianjin City and to further investigate the associated factors of high risk sexual behaviors, so as to provide a scientific and theoretical basis for accurate prevention and treatment of AIDS.@*Methods@#A stratified cluster random sample of 64 697 students in 56 colleges and universities in Tianjin City in November to December 2022 was investigated about the current status of AIDS knowledge, attitudes and practices. Information was collected using online survey via Questionnaire Star. Descriptive analysis was used for the current status of AIDS knowledge, attitudes and practices among college students. Chi square test and multiple Logistic regression analysis were used to analyze the influencing factors of high risk sexual behavior among college students.@*Results@#The AIDS awareness rate of college students in Tianjin City reached 87.33%. The sexual openness rate was 70.73 %. Among the 3 463 students who had sex during the past year, 42.13% of students reported high risk sexual behavior. Multivariate Logistic regression showed that female, having a romantic partner, having received sex education and prevention and treatment knowledge of AIDS were negatively associated with high risk sexual behavior ( OR =0.66, 0.59, 0.81, 0.59, P <0.05). Being in sophomore year, non heterosexuality (homosexuality, bisexuality, not knowing), prejudice against AIDS, and misunderstanding the testing methods for AIDS showed positive correlations with highrisk sexual behavior ( OR =1.22, 2.49, 2.30, 3.17, 1.43, 1.22 , P <0.05).@*Conclusions@#The awareness rate of AIDS in college students in Tianjin is high, but high risk sexual behaviors are still at a high level. Further targeted knowledge education and behavioral interventions are needed to scientifically prevent the spread of AIDS.
