Relation Between Perinatal Depressive Symptoms, Harm Avoidance, and a History of Major Depressive Disorder: A Cohort Study of Pregnant Women in Japan
Abstract
Introduction: The relationship between perinatal depressive symptoms, harm avoidance (HA), and a history of major depressive disorder (MDD) was examined in a prospective cohort study.Methods: This study was conducted from May 1, 2011, to December 31, 2016. A history of MDD was evaluated using the Inventory to Diagnose Depression, Lifetime version during pregnancy. Depressive state and HA were evaluated during pregnancy and at 1 month postnatal using the Edinburgh Postnatal Depression Scale (EPDS) and Temperament and Character Inventory, respectively. The relationship between these variances was examined using structural equation modeling.Results: A total of 338 participants with complete data were included in the present study. Pregnant women with compared with those without a history of MDD were observed to have a significantly higher intensity of HA and more severe depressive symptoms in both the prenatal and postnatal periods. A history of MDD affected the severity of depressive symptoms [standardized path coefficient (SPC) = 0.25, p < 0.001] and the intensity of HA during pregnancy (SPC = 0.36, p < 0.001). The intensity of HA during pregnancy affected that at 1 month postnatal (SPC = 0.78, p < 0.001), while the severity of depressive symptoms as assessed by the EPDS during pregnancy affected that at 1 month postnatal (SPC = 0.41, p < 0.001). The SPC for perinatal HA to postnatal depressive symptoms (SPC = 0.13, p = 0.014) was significant and higher than that for perinatal depressive symptoms to postnatal HA (SPC = 0.06, p = 0.087).Conclusion: The present results suggest that early intervention in pregnant women with a history of MDD or a high intensity of HA is important to prevent postnatal depressive symptoms.
