Stepwise regression model (table 4)
After variable selection (socio-demographic variables and variables with a P-value below 0.2 in the first analysis), early and late PPD have different explicative models. Thus, early PPD was significantly associated with a personal history of depression, emotional neglect in childhood, stressful life events during pregnancy as well as obstetric factors, and a concomitant chronic physical disease during pregnancy. While factors significantly associated with late PPD included: being unemployed, having a family history of mood disorder, a personal history of depression, emotional abuse in childhood, stressful life events during pregnancy, emergency consultations during pregnancy and postnatal complications (postpartum hemorrhage or ICU stay for the mother).
