HIV Prevalence and Risk Factors among Young Men Who Have Sex with Men in Southwest China: A Cross-Sectional Questionnaire Study
ABSTRACT
Background:
National surveillance data showed an increase of HIV infection among young men who have sex with men (YMSM) aged 25 years or younger in China.
Objective:
This study aimed to assess HIV prevalence and associated factors among YMSM in Guangxi Zhuang Autonomous Region, which was in Southwest China.
Methods:
Laboratory tests were performed to detect HIV and syphilis infections. A self-administered questionnaire was utilized to collect cross-sectional data from 632 YMSM.
Results:
The prevalence of HIV and syphilis was 9.3% and 11.4%, respectively. Multivariate logistic analysis showed that ethnic minority (AOR=2.45, 95%CI=1.39-4.33, P<0.05), receptive sexual positioning in the past 6 months (AOR=2.12, 95%CI=1.13-4.00, P<0.05), and current syphilis infection (AOR=2.63, 95%CI=1.33-5.20, P<0.05) were independently positively associated with HIV infection, while consistent condom use in anal intercourse in the past six months was negatively associated with HIV infection (AOR=0.53, 95%CI=0.30-0.96, P<0.05).
Conclusions:
There was an urgent need to scale up HIV and syphilis interventions in YMSM. Some subgroups might need specific attention for HIV prevention, including ethnic minority men, and individuals with a history of sexually transmitted infections and who have been engaging in receptive anal sex.
