Such illness may represent recurrence or exacerbation of a preexisting psychiatric disorder, or it may signal the onset of a new condition. Especially prevalent in pregnancy and the puerperium are depressive and anxiety disorders (Kendig, 2017). Many of these disorders are associated with less prenatal care, substance use, preterm delivery, and other poor obstetrical and neonatal outcomes. In affected gravidas, the postpartum psychiatric illness rate also is higher (Baer, 2016). Last, perinatal mood disorders can adversely hinder the mother-child relationship.
