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.

Objective@#To understand characteristics of men who have sex with men (MSM) who applied for HIV antibody self-testing reagents through "AIDS self-testing" column of a WeChat official account named "Dark Blue Public Health Center" in Tianjin City, so as to provide insights into exploring online modes of HIV antibody self-testing for MSM.@*Methods@#Data of MSM who were 18 years old or above, currently lived in Tianjin City, had sex with men in the past six months and applied for HIV antibody self-testing reagents through "AIDS self-testing" column from May 2018 to December 2022 were collected. Demographic characteristics, results return and positive findings were descriptively analyzed.@*Results@#Data of 2 064 MSM were collected, including 1 052 MSM aged 20 to 29 years (50.97%), 1 522 unmarried MSM (73.74%), 545 workers (26.41%), 1 385 MSM with college education or above (67.10%), and 315 MSM without testing for HIV antibody in the past (15.26%). A total of 6 470 self-testing reagents were applied, and 5 942 testing results were returned, with a return rate of 91.84%. There were 33.28% (687/2 064) of the applicants applying for 66.32% (4 291/6 470) reagents multiple times. There were 73 MSM with positive results, accounting for 1.23%.@*Conclusions@#The MSM applying for HIV antibody self-testing reagents through "AIDS self-testing" are mainly young and highly educated, including some who have never tested for HIV. However, attention should be paid to duplicate applications and the return rate should be increased.

Objective@#To investigate the detection of HIV/AIDS cases in medical institutions in Tianjin Municipality from 2005 to 2021, so as to provide insights into optimization of HIV antibody testing strategies in medical institutions.@*Methods@#All data pertaining to individuals receiving HIV antibody tests in medical institutions in Tianjin Municipality from 2005 to 2021 were collected from the information systems in medical institutions and the HIV/AIDS Prevention and Control Information System of Chinese Disease Prevention and Control Information System. The positive rate of HIV antibody and epidemiological characteristics of HIV/AIDS cases in medical institutions were analyzed.@*Results@#The number of HIV antibody tests increased from 86 102 person-times in 2005 to 1 369 345 person-times in 2021 in medical institutions in Tianjin Municipality, with annual increase by 18.88%. The positive rate of HIV antibody increased from 2.44/104 to 2.85/104 (P<0.05), with annual increase by 2.79/104. Both the proportion of the number of HIV antibody tests and the number of HIV/AIDS cases detected by medical institutions in the whole city appeared a tendency towards a rise (P<0.05). A high positive rate of HIV antibody was seen in sexually transmitted disease clinics (53.69/104) and other testing services (12.25/104), and the highest positive rate of HIV antibody was seen in individuals at ages of 20 to 39 years (5.40/104), while the positive rate of HIV antibody was higher in men (5.84/104) than in women (0.53/104) (P<0.05). A total of 3 610 HIV/AIDS cases were detected in medical institutions in Tianjin Municipality from 2005 to 2021, with a median age of 38 (interquartile range, 24) years. Of all HIV/AIDS patients, there were 3 277 men (90.78%), and men who have sex with men was the predominant transmission route (63.46%), while the proportion of late identification of HIV/AIDS cases was 65.60%. In addition, the proportion of timely detection for the first CD4+T lymphocyte count testing increased from 23.81% in 2005 to 71.54% in 2021 (P<0.05).@*Conclusions@#The number of HIV antibody tests and positive rate of HIV antibody appeared a tendency towards a rise in medical institutions in Tianjin Municipality from 2005 to 2021. The HIV/AIDS cases were predominantly identified in sexually transmitted disease clinics and other testing services, and were predominantly men.
