A hospital-based study of intimate partner violence during pregnancy.

Objective: To determine the prevalence and types of intimate partner violence (IPV) during pregnancy, factors linked with IPV, and effects of IPV on maternal-fetal outcomes.

Methods: In a prospective observational study at a tertiary care hospital in Delhi, India, 400 women at 20-28 weeks of pregnancy were screened for IPV between December 2013 and April 2015. The women completed a detailed questionnaire and were followed up until delivery.

Results: Overall, 49 (12.3%) women experienced IPV during pregnancy. The most prevalent type of IPV was emotional (43/400 [10.7%]), followed by physical (40/400 [10.0%]) and sexual (7/400 [1.8%]). The most prevalent factor triggering IPV was intimate partner's desire for a son (17/49 [34.7%]). Women and their intimate partners were older in the IPV group than in the control group, and duration of marriage was longer (P<0.05 for all). Multigravidity, lower socioeconomic status, low education level of intimate partner, and partners' addiction were more common in the IPV group (P<0.05 for all). Obstetric outcomes were similar in both groups. Depression was diagnosed in 19 (46.3%) women affected by IPV.

Conclusion: IPV was documented in approximately 12% of participants. Population-based surveys need to be done to investigate further.
