ABSTRACT Domestic violence during pregnancy is a critical health issue due to its significant implications for both maternal and fetal well-being. Women in South Asian countries are particularly at a higher risk of experiencing domestic violence. The objective of this study was to identify factors associated with domestic violence among pregnant women attending tertiary care antenatal services in Pakistan. The secondary aim was to evaluate the impact of domestic violence on maternal and perinatal outcomes. The study participants were 681 pregnant women registered for antenatal care and delivery at a tertiary care hospital in Islamabad, Pakistan. Data were collected through in-person surveys and medical chart reviews. Associations between domestic violence and study variables were examined by logistic regression analysis. Among the study participants, 31.4%experienced some form of domestic violence during pregnancy, with psychological abuse (16.4%) being the most prevalent followed by sexual abuse (9.5%) and physical violence (1.8%). Women whose husbands were unemployed were three times more likely to experience domestic violence (aOR; 3.3, 95%CI: 1.6, 7.0). Similarly, husband’s substance abuse was significantly associated with domestic violence during pregnancy (aOR: 120.8, 95%CI: 57.9, 252.2). Domestic violence was a significant predictor of adverse maternal outcomes, including anemia, preterm labor, and recurrent abdominal pain. Similarly, domestic violence was a significant predictor of NICU admission (aOR: 20.6, 95%CI: 12.6, 33.8) and low birthweight (aOR: 24.4, 95%CI: 10.2, 58.4). The study findings emphasize the urgent need for comprehensive interventions targeting domestic violence among women and preventing its cascading effects on pregnancies.
