A Systematic Review and Meta-Analysis of the Association between Childhood Exposure to Intimate Partner Violence and Intimate Partner Violence Victimization/Perpetration in Adulthood in Africa

Abstract

Intimate partner violence (IPV) is widespread in many African countries. Evidence, mainly from Western countries, shows that exposure to IPV in childhood is an important risk factor for experiences of IPV in adulthood. However, to date, no systematic review has synthesized the evidence on this association for individuals living in Africa, which is the goal of the current study. We used three search strategies: database searches (e.g., MEDLINE and PsycINFO), manual searches, and machine learning tools (e.g., Connected Papers). We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included peer-reviewed studies (in French or English) that reported quantitative or qualitative associations between childhood exposure to IPV and later IPV victimization/perpetration. A total of 48 studies from 29 African countries were included ( N = 520,000 participants). Pooled effects indicated an association between childhood exposure to IPV and IPV victimization for females (odds ratio [OR] = 2.46, 95% CI [2.09, 2.91], p < .001) and males (OR = 1.76, 95% CI [1.57, 1.97], p < .001). Similarly, males (OR = 1.92, 95% CI [1.60, 2.29], p < .001) and females (OR = 3.04, 95% CI [2.51, 3.69], p < .001) who were exposed to IPV in childhood were more likely to perpetrate IPV compared to those with no childhood exposure. Effect sizes varied substantially across studies (0.89–5.66), suggesting that other risk factors should be considered in future studies. This review provides unique insights on cycles of IPV in Africa that may usefully inform practice and research.
