To assess the prevalence and exacerbating factors of intimate partner violence in people living with HIV in China, we conducted a cross-sectional study, involving 2792 people living with HIV (PLHIV) in four provinces in China from Sep 1, 2020, to Jun 1, 2021. The category of Intimate partner violence (IPV) included physical violence, sexual violence, emotional abuse and controlling behavior. The severity of a violent act was divided into mild, moderate and severe. Among PLHIV, the prevalence of IPV was 15.4% (95% CI: 14.1-16.8%). The severity of physical violence was mainly moderate, and the severity of sexual violence, emotional abuse and controlling behavior was mainly mild. The prevalence of IPV in men was higher than that in women. Results from the multivariable logistic regression showed that age, ethnic, registered residence, education, and duration of HIV ART were factors related to IPV in PLHIV (P < 0.05).
