Factors associated with disclosing men who have sex with men (MSM) sexual behaviors and HIV-positive status: A study based on a social network analysis in Nanjing, China.

Abstract

We explored the factors associated with disclosure of men who have with sex with men (MSM) behaviors and HIV-positive status among HIV-positive MSM in Nanjing, China. Social network analysis and epidemiological methods were combined in this pilot study. Information about participants' (egos') characteristics and behaviors and their social network members (alters) were collected through interview-administered questionnaires. General estimating equation logistic regression analysis was applied in both univariate and multivariate analysis. Eighty-seven HIV-positive MSM participated. Their mean age was 35.9 ±13.81years. They were more likely to disclose their MSM behavior to their friends [adjust Odds Ratio (AOR) = 6.43, 95% confidence interval (CI):3.08-13.42] or to the social network members who were not heterosexual [AOR = 4.40, 95%CI: 2.17-8.91]. Being participants' friends [AOR = 5.16, 95%CI: 2.03-13.10] or family members [AOR = 6.22, 95%CI: 2.52-15.33] was significantly associated with HIV-positive status disclosure. HIV-positive MSM tended to disclose their MSM behaviors and HIV positive status to close friends, family members or other individuals who were HIV-positive, engaging in MSM behavior, or both. Consequently, it will be an effective way to implement HIV prevention and intervention strategies in both MSM population and their trusted social networks.
