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.

非洲童年时期暴露于亲密伴侣暴力与成年期亲密伴侣暴力受害/实施之间关联的系统评价和荟萃分析


亲密伴侣暴力 （IPV） 在许多非洲国家很普遍。主要来自西方国家的证据显示，儿童时期暴露于 IPV 是成年期经历 IPV 的重要危险因素。然而，迄今为止，还没有系统评价综合了生活在非洲的个体的这种关联的证据，这是当前研究的目标。我们使用了三种检索策略：数据库检索（例如MEDLINE和PsycINFO）、手动检索和机器学习工具（例如Connected Papers）。我们遵循系统评价和荟萃分析的首选报告项目指南，并纳入了同行评审研究（法语或英语），这些研究报告了儿童期暴露于 IPV 与后来的 IPV 受害/实施之间的定量或定性关联。共纳入来自 29 个非洲国家的 48 项研究 （ N = 520,000 名参与者）。汇总效应表明，女性 （OR = 2.46， 95% CI [2.09， 2.91]，p < .001） 和男性 （OR = 1.76， 95% CI [1.57， 1.97]，p < .001） 的儿童期暴露与 IPV 受害之间存在关联。同样，与童年未暴露于儿童期的人相比，在儿童期暴露于 IPV 的男性 （OR = 1.92， 95% CI [1.60， 2.29]，p < .001） 和女性 （OR = 3.04， 95% CI [2.51， 3.69]，p < .001） 更有可能实施 IPV。不同研究的效应量差异很大 （0.89-5.66），表明在未来的研究中应考虑其他风险因素。本综述提供了关于非洲 IPV 周期的独特见解，可能为实践和研究提供有用的信息。
