Prenatal sleep quality and mental health symptoms across the perinatal period: A longitudinal study of high-risk women

Abstract

BackgroundTrauma-exposed women may be at magnified risk for posttraumatic stress (PTSS) and depression symptoms in the perinatal period, but few studies have examined symptomatology across the perinatal period in high-risk samples. Further, the role of sleep in perinatal symptomatology has been largely neglected in the violence literature, despite its well-established associations to mental health in other samples. This study aimed to examine the trajectory of PTSS and depression symptoms across the perinatal period and the effects of childhood adversity, intimate partner violence and prenatal sleep impairment on PTSS and depression symptoms across the perinatal period. MethodIn a longitudinal, prospective study, 101 low-income pregnant women were interviewed during pregnancy, at 6-weeks postpartum, and 4 months postpartum. N = 83 women completed at least 2 interviews and were included in the analyses. Prenatal sleep, childhood adversity, and IPV exposure were assessed at the prenatal interview; PTSS and depression were assessed at all interviews. ResultsPast year IPV was associated with elevated prenatal mental health symptoms and prenatal sleep difficulties were associated with a worsening trajectory in perinatal PTSS. ConclusionsScreening for IPV and prenatal sleep difficulties may be paramount in identifying those at risk for the development or exacerbation of mental health symptoms in the perinatal period.
