“…Studies suggest that 14.8% to 40.7% (median = 35%) of mothers with PPD still met criteria for major depression with EPDS > 13 at less than 3 month (n = 8 studies 12,16,18,20,21,23,28,38 ); 27.4% at 1 week (n = 1 study 30 ) 38% to 44% (median = 39%) at 1 month (n = 3 studies 6,40,41 ); 30% to 39% (median = 36%) at 4 to 12 weeks (n = 3 studies 15,24,47 ); 12% to 36.3% (median 23.3%) at 2 months (n = 4 studies 4,27,32,44 ); and 30% to 80% (median = 33%) at 3 months (n = 6 studies 4,14,22,26,42,46 ); 9.6% to 60% (median = 27%), duration of months is not applicable (n = 11 studies 13,17,19,25,29,34,39,43,45,46 ), 12.4% at <5 months (n = 1 study 22 ). Overall, these findings suggest that at any time point between 1 week and <5 months postpartum, about 27% of mothers diagnosed with PPD still meet criteria for depression.…”
