Prevalence of depressive symptoms in the immediate postpartum period.

Purpose: There is currently little information about rates of positive maternal depression screens immediately after delivery; rather, most studies have assessed the prevalence of major depression between 1 and 6 months postpartum. This study investigated the rate of positive 9-item Patient Health Questionnaire (PHQ-9) surveys within 1 to 2 days after delivery.

Methods: A retrospective chart review of PHQ-9 results obtained within 1 to 2 days after childbirth was performed on 441 women who delivered at 3 St. Paul, MN, hospitals during February 2010.

Results: Out of 441 deliveries recorded during the study period, PHQ-9 results were available for 361 women (81.9%). A total of 9 women (2.5%) had positive PHQ-9 scores within 1 to 2 days after delivery.

Conclusion: We found very low rates of depressive symptoms during the immediate postpartum period, which leads us to suggest that this is not an ideal time for postpartum depression screening or evaluation.
