Risk factors for depressive symptoms in early postpartum period and after puerperium - are they the same?

OBJECTIVES: Correlation between the occurrence of postnatal depressive symptoms at 5 days and 6 weeks postpartum is well established. The objective of the study was to determine the influence of psychosocial and perinatal factors on the occurrence of postpartum depressive symptoms 2 to 5 days and 6 weeks after delivery.

METHODS: 373 women in early postpartum (EPG) and 107 women 6 weeks after delivery (late postpartum group - LPG) completed a questionnaire including questions concerning mothers' characteristics, obstetric and neonatal complications during pregnancy, psychiatric factors and Edinburgh Postnatal Depression Scale (EPDS).

RESULTS: 21.6% of mothers from EPG and 14.2% in LPG achieved ≥10 points in EPDS. In both groups patients with ≥10 points reported stressful situations during pregnancy, sedative agents usage and a history of suicidal attempts. In EPG women with ≥10 points significantly more frequent delivered preterm, were hospitalized during pregnancy and their newborns had more health problems. In LPG mothers with ≥10 points more often reported several obstetric complications. Maternal comorbidity or sociodemographic factors did not correlate with the risk of depressive symptoms.

CONCLUSION: The risk factors for depressive symptoms after delivery vary in different time intervals. Therefore screening for PD should not be performed once in a single selected risk group.
