To the Editor Research on perinatal mental disorders other than postnatal depression is long overdue; therefore, we were pleased to see the study by Yonkers et al,1 which reported a 4-fold elevated risk for preterm birth in women who had a likely diagnosis of posttraumatic stress disorder or a major depressive episode. However, we were concerned by the omission of any measure of domestic violence in the study, as domestic violence is a correlate of posttraumatic stress disorder and major depression in pregnancy2 and of adverse pregnancy outcomes including preterm birth.3
