Prevalence of physical and sexual assault in pregnant adolescents.

Few studies have addressed the prevalence of violence among pregnant adolescents. We interviewed 342 pregnant teenagers 17 years of age or younger for a history of assault; 9% reported physical assault, 8% sexual assault, and 8% both physical and sexual assault. Of those physically abused, 40% had been hit during pregnancy. The most common perpetrator of physical assault was a member of their family of origin as compared to a mate (46% versus 33%), although a boyfriend or spouse was the attacker in 80% of cases in which abuse had increased during pregnancy. The face or neck was the most common site of contact. A total of 14% reported being hit in the abdomen, one-third of them while pregnant. We conclude that a significant proportion of pregnant teenagers have experienced violence and therefore should be screened routinely for a history of abuse.
