A significant proportion of women of reproductive age experience situations of intimate partner violence. The periods of prenatal and childcare consultations are opportunities for healthcare professionals to identify situations of violence.

OBJECTIVE To estimate the incidence and identify risk factors for intimate partner violence during postpartum.METHODS This prospective cohort study was conducted with women, aged between 18-49 years, enrolled in the Brazilian Family Health Strategy in Recife, Northeastern Brazil, between 2005 and 2006. Of the 1.057 women interviewed during pregnancy and postpartum, 539 women, who did not report violence before or during pregnancy, were evaluated. A theoretical-conceptual framework was built with three levels of factors hierarchically ordered: women’s and partners’ sociodemografic and behavioral characteristics, and relationship dynamics. Incidence and risk factors of intimate partner violence were estimated by Poisson Regression.RESULTS The incidence of violence during postpartum was 9.3% (95%CI 7.0;12.0). Isolated psychological violence was the most common (4.3%; 95%CI 2.8;6.4). The overlapping of psychological with physical violence occurred at 3.3% (95%CI 2.0;5.3) and with physical and/or sexual in almost 2.0% (95%CI 0.8;3.0) of cases. The risk of partner violence during postpartum was increased for women with a low level of education (RR = 2.6; 95%CI 1.3;5.4), without own income (RR = 1.7; 95%CI 1.0;2.9) and those who perpetrated physical violence against their partner without being assaulted first (RR = 2.0; 95%CI 1.2;3.4), had a very controlling partner (RR = 2.5; 95%CI 1.1;5.8), and had frequent fights with their partner (RR = 1.7; 95%CI 1.0;2.9).CONCLUSIONS The high incidence of intimate partner violence during postpartum and its association with aspects of the relationship’s quality between the couple, demonstrated the need for public policies that promote conflict mediation and enable forms of empowerment for women to address the cycle of violence.

The results of this study are consistent with the hypothesis that women's exposure to intimate partner violence during pregnancy may be associated with behavioral problems of their children, emphasizing the need for greater understanding about the vulnerability of children to adversity in early ages.

Background: Exposure to intimate partner violence (IPV) is an important adverse childhood experience, but there are few longitudinal studies in low and middle-income countries.Objective: To investigate the consequences of exposure to IPV for the child's mental health.Participants and Setting: 614 mother-child pairs were evaluated in a poor urban district in Recife, northeastern Brazil. Methods: A prospective cohort study enrolled pregnant women in 2005-2006. Women were interviewed in pregnancy, postpartum and six to nine years after delivery, and asked about their experience of IPV, and the exposure of their child to violence. The Strengths and Difficulties Questionnaire (SDQ) was completed by child's mother and teacher. Ten types of child experience of IPV and the age of onset of exposure were compared with the child's behavioral profile at school age.Results: The commonest types of child exposure to IPV were "prenatally", "overheard" "eyewitnessed";10.0% of children were physically or verbally involved in the IPV. Mothers reported high SDQ Total Difficulties scores in 71.7% of all children exposed to IPV and teachers in 59.8%. Multivariate analyses demonstrated associations between exposures to IPV with SDQ scores. The strongest association with behavioral difficulties was with exposure in the age group 1-2 years (OR 2.5 [95% CI: 1.3-4.8]). Conclusions:Young children are sensitive to the age of first exposure to IPV and to the type of IPV. Interventions to reduce IPV should be targeted on vulnerable women from poor urban communities during their pregnancies and in the first two years of their child's life.

OBJECTIVE To estimate differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy.METHODS A nested case-control study was carried out within a cohort study with 1,120 pregnant women aged 18–49 years old, who were registered in the Family Health Strategy of the city of Recife, State of Pernambuco, Brazil, between 2005 and 2006. The cases were the 233 women who reported intimate partner violence in pregnancy and the controls were the 499 women who did not report it. Partner violence in pregnancy and previous experiences of violence committed by parents or other family members were assessed with a standardized questionnaire. Multivariate logistic regression analyses were modeled to identify differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy.RESULTS Having seen the mother suffer intimate partner violence was associated with physical violence in childhood (OR = 2.62; 95%CI 1.89–3.63) and in adolescence (OR = 1.47; 95%CI 1.01–2.13), sexual violence in childhood (OR = 3.28; 95%CI 1.68–6.38) and intimate partner violence during pregnancy (OR = 1.47; 95% CI 1.01 – 2.12). The intimate partner violence during pregnancy was frequent in women who reported more episodes of physical violence in childhood (OR = 2.08; 95%CI 1.43–3.02) and adolescence (OR = 1.63; 95%CI 1.07–2.47), who suffered sexual violence in childhood (OR = 3.92; 95%CI 1.86–8.27), and who perpetrated violence against the partner (OR = 8.67; 95%CI 4.57–16.45).CONCLUSIONS Experiences of violence committed by parents or other family members emerge as strong risk factors for intimate partner violence in pregnancy. Identifying and understanding protective and risk factors for the emergence of intimate partner violence in pregnancy and its maintenance may help policymakers and health service managers to develop intervention strategies.
