Clinical investigation of postpartum depression risk factors and screening predictors

Figure 1 Comparison of obstetric risk factors between the postpartum depression and non- postpartum depression groups. This figure illustrates the significantly higher percentages of primiparas, unplanned pregnancies, cesarean section, and premature rupture of membranes in the postpartum depression (PPD) group than in the non-PPD group. All four obstetric factors were significantly different between the groups, suggesting that these factors may be important risk factors for developing PPD. ^aP < 0.05. PPD: Postpartum depression; PROM: Premature rupture of membranes.
