ObjectiveTo review the extant literature on the effect of traumatic experiences that pre-date conception, pregnancy, and the postpartum period (perinatal period) and present a thematic overview of current issues in this relatively new area of inquiry. Data SourcesElectronic databases Cochrane, CINAHL, PsychINFO, and PubMed were searched. Manual searches of reference lists supplemented the electronic search. Study SelectionPeer-reviewed articles written in English on the role of posttraumatic stress disorder during the perinatal period were included. Data ExtractionKey findings relevant to perinatal posttraumatic stress that were reported in primary sources and meta-analyses were organized according to themes, including The Role of Childbirth, Comorbidity With Depression and Anxiety, Risk Factors for Perinatal PTSD, High-Risk Health Behaviors, and Association With Adverse Health Outcomes. Data SynthesisAcross studies, antenatal posttraumatic stress disorder (PTSD) rates were estimated between 2.3% and 24%, and observed prevalence rates during the postnatal period ranged from 1% to 20%; however, many researchers failed to assess PTSD that existed before or during pregnancy, and when preexisting PTSD is a controlled variable, postpartum rates drop to 2% to 4.7%. In addition to prenatal depression and anxiety and pre-pregnancy history of psychiatric disorders, history of sexual trauma, childhood sexual abuse, intimate partner violence, and psychosocial attributes are risk factors for development or exacerbation of perinatal PTSD. ConclusionWomen's health care providers should evaluate for PTSD in routine mental health assessments during and after pregnancy, especially with a reported history of trauma or the presence of a mood or anxiety disorder. Such screening will allow women to receive needed treatment and referrals and mitigate the potentially negative sequelae of PTSD. Future investigators must recognize the importance of subsyndromal posttraumatic stress symptoms and individual differences in responses to trauma.
