Intimate partner violence and childhood health outcomes in 37 sub-Saharan African countries: an analysis of demographic health survey data from 2011 to 2022

Background: Understanding the contribution of intimate partner violence (IPV) to childhood health outcomes (eg, morbidity and mortality) is crucial for improving child survival in sub-Saharan Africa. This comprehensive study aimed to explore the associations between maternal exposure to physical, sexual, or emotional violence and adverse childhood health outcomes in sub-Saharan Africa. Methods: We analysed Demographic Health Survey datasets from 37 sub-Saharan African countries from 2011 to 2022. A generalised linear mixed model was used to examine the associations between maternal physical violence, sexual violence, or emotional violence, and early childhood health outcomes (eg, acute respiratory infection, diarrhoea, undernutrition, and child mortality). A random effects meta-analysis was used to calculate pooled odds ratios (ORs) for adverse childhood health outcomes. The odds of undernutrition and mortality were 55% and 58% higher among children younger than 5 years born to mothers who were exposed to physical and sexual violence, respectively. Findings: 238 060 children younger than 5 years were included. Children whose mothers experienced physical violence (adjusted OR 1·33, 95% CI 1·29–1·42), sexual violence (1·47, 1·34–1·62), emotional violence (1·39, 1·32–1·47), or a combination of emotional and sexual violence (1·64, 1·20–2·22), or a combination of all the three forms of violence (1·88, 1·62–2·18) were associated with an increased odds of developing diarrhoeal disease. Similarly, children whose mothers experienced physical violence (1·43, 1·28–1·59), sexual violence (1·47, 1·34–1·62), emotional violence (1·39, 1·32–1·47), or a combination of emotional and sexual violence (1·48, 1·16–1·89), or a combination of all three forms of violence (1·66, 1·47–1·88) were positively associated with symptoms of acute respiratory infection. Interpretation: We found a strong link between maternal exposure to IPV and health outcomes for children younger than 5 years in sub-Saharan Africa, with minor variations across countries. To address childhood morbidity and mortality attributed to IPV, interventions need to be tailored for specific countries. Burkina Faso, Burundi, Chad, Comoros, Gabon, Liberia, Nigeria, Sierra Leone, South Africa, and Uganda should be priority nations. Funding: None.
