Sexual violence and pregnancy-related physical symptoms

BACKGROUND Few studies have investigated the impact of sexual violence on health during pregnancy. We examined the association between sexual violence and the reporting of physical symptoms during pregnancy. METHODS A population-based national cohort study conducted by The Norwegian Mother and Child Cohort study (MoBa) collected data from pregnant women through postal questionnaires at 17 and 32 weeks gestation. Three levels of sexual violence were measured: 1) mild (pressured into sexual relations), 2) moderate (forced with violence into sexual relation) and 3) severe (rape). Differences between women reporting and not reporting sexual violence were assessed using Pearson's X2 test and multiple logistic regression analyses. RESULTS Of 78 660 women, 12.0% (9 444) reported mild, 2.8% (2 219) moderate and 3.6% (2 805) severe sexual violence. Sexual violence was significantly associated with increased reporting of pregnancy-related physical symptoms, both measured in number of symptoms and duration/degree of suffering. Compared to women not reporting sexual violence, the probability of suffering from ≥8 pregnancy-related symptoms estimated by Adjusted Odds Ratio (AOR) was 1.49 (1.41-1.58) for mild sexual violence, 1.66(1.50-1.84) for moderate and 1.78 (1.62-1.95) for severe. Severe sexual violence both previously and recently had the strongest association with suffering from ≥8 pregnancy-related symptoms, AOR 6.70 (2.34-19.14). CONCLUSION A history of sexual violence is associated with increased reporting of pregnancy-related physical symptoms. Clinicians should consider the possible role of a history of sexual violence when treating women who suffer extensively from pregnancy-related symptoms.
