Analysis on the characteristics and influencing factors of commercial sexual behavior among men who have sex with men infected with HIV.

Objective To describe the characteristics of commercial sexual behavior of HIV-infected men who have sex with men (MSM) and analyze its influencing factors. Methods An anonymous questionnaire survey was conducted through the recruitment of HIV-infected MSM by two social organizations in Chongqing. The x² test was used to compare the commercial sexual behavior of HIV infected with MSM with different social demographic characteristics, mental health status, and sexual behavioral characteristics. Multivariate Logistic regression model was used to analyze the influencing factors of commercial behavior. Results A total of 1 501 cases of HIV infection with MSM were investigated in this study. In total 12.50% of the respondents reported same-sex commercial sex in the past six months, of which 28.34% reported unprotected commercial sex behavior. The results of multivariate Logistic regression showed HIV-infected MSM with marital status as marriage/cohabitation (OR =2.345, 95%CI: 1.442-3.814), working status as part-time and others (OR=6.522, 95%CI: 3.575-11.900), monthly income exceeding 5 000 yuan (OR=7.890, 95%CI: 4.254-14.634), age of first sexual intercourse less than 18 years old (OR= 1.818, 95%CI: 1.014-3.260), using same-sex dating software (using one: OR=2.984, 95%CI: 1.477-6.030; using two: OR = 3.683, 95%C$: 1.650-8.221; using 3 and above: OR=21.777, 95%CI: 8.349-56.804), drinking (0R=2.528, 95%C$: 1.5684.074), and using Rush (OR=3.114, 95%CI: 1.988-4.877) were more likely to have commercial sexual behavior (P < 0.05). Conclusion The commercial sexual behavior of HIV infection with MSM is common in Chongqing, and the proportion of commercial sexual behavior without condom is high_ Comprehensive measures should be taken to intervene the drinking, Rush use, and commercial sexual behavior of this population in order to reduce the further spread of HIV/STIs.
