Association between intimate partner violence against women and HIV infection

OBJECTIVE: To analyze the association between intimate partner violence against women and infection or suspected infection by the human immunodeficiency virus (HIV). METHODS: A cross-sectional study was conducted, based on data from questionnaires applied face-to-face and medical records of 2,780 women aged between 15 and 49 years, cared for in Sistema Unico de Saude (Unified Health System) units of the Greater Sao Paulo area, Southeastern Brazil, in 2001-2002. Women were categorized into: users in treatment because they are HIV seropositive, those suspected of having HIV and others who sought health services for different reasons. Intimate partner violence against women throughout life was categorized according to the severity and recurrence of episodes of violence. The association with the outcome was tested using the Poisson model with robust and adjusted variance for sociodemographic, sexual and reproductive variables. RESULTS: The prevalence of violence was 59.8%. Suffering repeated and severe violence was more closely associated with confirmed HIV infection (PR = 1.91). Violence independent from severity and recurrence of episodes showed greater association with suspected HIV infection (PR = 1.29). CONCLUSIONS: Intimate partner violence against women has a key role in situations of suspected and confirmed HIV infection. Thus, it is essential to include its detection, control and prevention as part of the comprehensive care provided for women's health.
