2.Analysis of potential categories of sexual behaviors among male students who have sex with men and the status of pre exposure prophylaxis use
Chinese Journal of School Health 2024;45(7):974-977
Objective:
To analyze the use of preexposure prophylaxis (PrEP) among male students who had sex with men (MSM) with different sexual behavior patterns using potential categories, so as to provide evidence for determining the use patterns of PrEP consistent with MSM.
Methods:
A questionnaire survey was conducted by proportional sampling method on MSM in 31 provincial administrative regions in mainland China from 20 October to 30 December 2021, a total of 1 040 students were selected for the study. Latent variable analyses were conducted on a total of seven sexual behavioral characteristics, including knowledge of sexual partner HIV infection, frequency of condom use, number of sexual partners, engaging in group sex, provision of commercial sex, use of sex aids, and history of sexually transmitted infections (STIs) in the past year. And demographic characteristics were analyzed by Logistic regression analysis. The rates of PrEP awareness, willingness to use and usage rate in different sexual behavior risk groups were investigated.
Results:
Student MSM could be divided into two potential category groups:a lowrisk behavior group (82.4%) and a highrisk behavior group (17.6%). The PrEP usage rate (15.8%) was higher in the highrisk behavior group, and the difference was statistically significant compared to the lowrisk behavior group (7.2%) (χ2=13.43, P<0.05). Student MSM residing in the northeast, south, and northwest of China, in the pilot city, and with a sex role of "0.5" (possible acceptance and insertion of sexual behavior) were more likely to be in the highrisk behavior group (OR=3.13, 3.07, 3.87, 2.22, 1.66, P<0.05).
Conclusion
Student MSM in highrisk and lowrisk sexual differs in the behavior of PrEP, and targeted interventions should be implemented to promote the use of PrEP and reduce HIV infection in this population.
