Abstract

BACKGROUND: Partner violence against women is common during pregnancy and might have an adverse effect on the mental health of women after delivery. We aimed to investigate the association of postnatal depression with psychological, physical, and sexual violence against women by their intimate partners during pregnancy. METHODS: In a prospective cohort study undertaken in Recife, northeastern Brazil, between July, 2005, and December, 2006, we enrolled pregnant women (aged 18-49 years) in their third trimester of pregnancy who were attending primary health-care clinics. The women were interviewed during pregnancy and after delivery. The form of partner violence in pregnancy was assessed with a validated questionnaire, and the Edinburgh postnatal depression scale was used to measure postnatal depression. Associations were estimated with odds ratios (ORs), adjusted for confounding factors contributing to the association between postnatal depression and intimate partner violence. FINDINGS: 1133 pregnant women were eligible for inclusion in the study, of whom 1045 had complete data for all variables and were included in the analysis. 270 women (25.8%, 95% CI 23.2-28.6) had postnatal depression. The most common form of partner violence was psychological (294 [28.1%, 25.4-31.0]). Frequency of psychological violence during pregnancy was positively associated with occurrence of postnatal depression, and although this association was attenuated after adjustment, women reporting the highest frequency of psychological violence were more likely to have postnatal depression even after adjustment (adjusted OR 2.29, 95% CI 1.15-4.57). Women who reported physical or sexual violence in pregnancy were more likely to develop postnatal depression (OR 3.28, 2.29-4.70), but this association was substantially reduced after adjustment for psychological violence and confounding factors. INTERPRETATION: Psychological violence during pregnancy by an intimate partner is strongly associated with postnatal depression, independently of physical or sexual violence. This finding has important policy implications since most social policies focus on prevention and treatment of physical violence.
