Abstract:
Objective:To explore changes in high-risk sexual behaviors and associated factors in HIV-infected men who have sex with men (MSM) in industrial workers, and provide evidence for designing behavioral interventions for this population.Methods:In this observational study, HIV-infected MSM were recruited in industrial workers using convenient sampling during August to September 2021. The sample size was estimated to be 530. A questionnaire was used and combined with routine follow-up to collect socio-demographic characteristics, high-risk sexual behaviors, partner notification, viral load testing and history of sexually transmitted diseases before and after diagnosis of HIV infection. The χ2 test was used to analyze the changes in high-risk sexual behaviors before and after diagnosis and logistic regression was conducted to identify factors associated with high-risk sexual behaviors. Results:A total of 560 HIV-infected MSM in industrial workers were recruited in this study. Of whom, 32.1% (180/560) had unprotected anal intercourse (UAI) within 12 months after diagnosis . The proportions of those having UAI with casual, commercial and regular same-sex partners significantly decreased from 73.4% (381/519), 75.1% (187/249) and 69.5% (207/298) within 12 months before diagnosis to 36.2% (146/403), 40.2% (86/214) and 34.2% (67/196) within 12 months after diagnosis , respectively. Educational level of college or above (a OR=0.41, 95% CI:0.23-0.71), passive anal sex (a OR=0.40, 95% CI:0.19-0.85), both active and passive anal sex after diagnosis (a OR=0.40, 95% CI:0.20-0.83) and no unprotected oral sex (a OR=0.02, 95% CI:0.01-0.05) were negatively associated with UAI within 12 months after diagnosis. Whereas, not considering necessary to use condom consistently after having repeated undetectable viral load (a OR=3.02, 95% CI:1.37-6.69) was positively associated with UAI within 12 months after diagnosis. Conclusions:Compared with that before diagnosis of HIV infection, although the prevalence of UAI seemed to decrease in HIV-infected MSM in industrial workers after diagnosis, nearly one third of them had high-risk sexual behaviors. Therefore, relevant interventions should be strengthened to reduce high-risk sexual behaviors.
