This study assesses the prevalence, types, and pattern of intimate partner violence (IPV) during lifetime and current pregnancy for 2,392 women in Lima, Peru. The reported lifetime prevalence of any IPV (physical, sexual, or emotional) is 45.1%. For women who experienced abuse, the prevalence of lifetime physical, emotional, and sexual IPV is 34.2%, 28.4%, and 8.7%, respectively. Older (ĝ‰¥ 30 years), unmarried, employed, and economically disadvantaged women and those with little education are more likely to experience lifetime and pregnancy IPV. Efforts at universal antepartum IPV screening and appropriate interventions are needed to reduce the burden of violence experienced by pregnant women. © 2009 Sage Publications.
