Exposure to interparental violence and risk of intimate partner violence among women in sexual unions in sub-Saharan Africa.

Background: Intimate partner violence (IPV) has emerged as a serious human rights issue as well as a public health concern globally. We examined the association between exposure to interparental violence and experience of intimate partner violence (IPV) among women in sub-Saharan Africa (SSA) using Demographic and Health Survey (DHS) data.
Methods: We included 96 782 women in 23 countries with a recent DHS dataset conducted from 2012 to 2020. We employed multivariable multinomial logistic regression to examine the association between exposure to interparental violence and experience of IPV.
Results: Overall, women who were exposed to interparental violence were more likely to experience physical (adjusted OR [aOR]=2.17, 95% CI 2.07 to 2.28), emotional (aOR=1.87, 95% CI 1.78 to 1.96) and sexual violence (aOR=2.02, 95% CI 1.90 to 2.15) than those who were not exposed. In all countries except Comoros, women exposed to interparental violence had higher odds of physical and emotional violence than those who were not exposed. Experience of sexual violence was higher among women exposed to interparental violence from all countries except for Liberia, Rwanda and Sierra Leone.
Conclusions: Women's exposure to interparental violence increases their risk of experiencing IPV. Policies should focus on women or young girls who who witness IPV to reduce their likelihood of experiencing it. Special support can be provided for women who were exposed to interparental violence and are currently experiencing IPV.
