Women that experience recent intimate partner violence (IPV) are three times more likely to contract HIV, according to a new study led by McGill University researchers. In regions like Sub-Saharan Africa, women face an intersecting epidemic of intimate partner violence and HIV.

“Worldwide, more than one in four women experience intimate partner violence in their lifetime,” says McGill University Professor Mathieu Maheu-Giroux, a Canada Research Chair in Population Health Modeling.

“Sub-Saharan Africa is among one of the regions in the world with the highest prevalence of both IPV and HIV. We wanted to examine the effects of intimate partner violence on recent HIV infections and women’s access to HIV care in this region,” he says.

Their study, published in The Lancet HIV, shows considerable overlap between violence against women and the HIV epidemics in some of the highest burdened countries. Among women living with HIV, those experiencing intimate partner violence were nine percent less likely to achieve viral load suppression—the ultimate step in HIV treatment.

New calls to eliminate all forms of sexual and gender-based violence

“The 2021 UN General Assembly, attended and supported by the Government of Canada, adopted the Political Declaration on HIV and AIDS with bold new global targets for 2025. This encompasses a commitment to eliminate all forms of sexual and gender-based violence, including IPV, as a key enabler of the HIV epidemic. Improving our understanding of the relationships between IPV and HIV is essential to meet this commitment,” says Professor Maheu-Giroux.

The researchers found that physical or sexual intimate partner violence in the past year was associated with recent HIV acquisition and less frequent viral load suppression. According to the researchers, IPV could also pose barriers for women in accessing HIV care and remaining in care while living with the virus.
