Intimate partner violence victimization and HIV infection among men who have sex with men in Shanghai, China.

Intimate partner violence (IPV) and its association with HIV infection among men who have sex men (MSM) in China are not understood. In this study, 732 MSM recruited from Shanghai, China between March and August 2015 were administered with a questionnaire survey and HIV blood testing. IPV victimization was measured by 25 forced-choice items capturing lifetime experience of physical, sexual, psychological, deprivation or neglect, and other forms of violence. Of them, 179 (24.3%) reported having experienced at least one type of IPV victimization. In separate multivariable analyses, sexual violence was associated with age over 35 years (AOR = 0.26, 95% CI: 0.07-1.02), ever had male-to-male commercial sex (AOR = 2.53, 95%CI: 1.19-5.39), and diagnosis of a sexually transmitted infection (STI) (AOR = 2.14, 95%CI: 0.98-4.66). Both psychological violence (AOR = 2.53, 95%CI: 1.25-5.12)and deprivation or neglect violence (AOR = 1.75, 95%CI: 1.14-2.68) were associated with ever had sex with a casual male partner(s). Having experienced at least one type of IPV victimization was significantly associated with ever had sex with a causal partner(s) (AOR = 1.72, 95%CI: 1.15-2.57) and ever had a diagnosis of a STI (AOR = 1.80, 95% CI: 1.12-2.88). HIV infection was marginally associated with having experienced any form of IPV victimization. IPV victimization is common among MSM, especially young MSM, in China, although its association with HIV infection is not conclusive in our sample. Nonetheless, our findings highlight the importance of the needs of individualized IPV interventions for certain target risk groups of MSM.
