Violence against women (VAW) is a major human rights and public health concern, with significant impacts on women’s health [1, 2], including increased vulnerability to HIV [3, 4]. Intimate partner violence (IPV) is the most common form of violence against women, with 30% of women globally experiencing it during their lifetime . There is now a growing body of evidence on the impact of prevention interventions on HIV and IPV in different contexts. In South Africa, the IMAGE Study assessed the impact of a combined microfinance programme and participatory gender and HIV training . The cluster randomized study found that the intervention led to a 55% reduction in past year IPV over two years and among younger participants was associated with increases in HIV testing and reduced prevalence of unprotected sex at last intercourse with a non-spousal partner . The programme has been scaled up in South Africa and is currently being replicated in Tanzania as part of the MAISHA study . Stepping Stones, a participatory HIV prevention programme which includes gender, relationship education and IPV content, has been used throughout Africa and evaluated extensively. A cluster randomized control study in South Africa found that after a two year follow up period there was no association between the intervention and a reduction in HIV, but there was an association with a 33% reduction in HSV-2 incidence. Reductions were also observed among men in reported levels of IPV perpetration against women and sexual risk behaviours . And, more recently a randomized control trial of the Bandebereho gender-transformative couples’ intervention in Rwanda found that compared to the control group, women in the intervention group reported less past-year physical (OR 0.37, p < 0.001) and sexual IPV (OR 0.34, p < 0.001) . The program engages men and their female partners (for some sessions) on topics including gender and power, IPV, couple communication and parenting.
