Childbirth-related episiotomy and tear in relation to risk of postpartum depression: a retrospective cohort study on Omani mothers

Aims/Background: Studies on the association between perineal trauma (episiotomy and tear) and the risk of postpartum depression in Omani mothers are scarce. This study aimed to screen women for the risk of postpartum depression and associated maternal adverse outcomes (episiotomy and tear) in newly delivered Omani mothers. Design/Methods: Mothers were screened for postpartum depression using only the Edinburgh Postnatal Depression Scale (EPDS), with cut-offs of 1–12 indicating low risk and 13–30 indicating high risk. Data on birth outcomes were collected retrospectively from the medical records. Descriptive analyses, group comparisons, and linear regression analyses were conducted. Results: Of the 262 participating mothers (total sample, i.e. mothers with and without depression), 19.0% had an episiotomy, 29.0% had tears, and 52.0% had an intact perineum after their childbirth. The total EPDS score was significantly higher among mothers with episiotomy (10.4, SD = 5.4) compared to those with tears (8.1, SD = 4.8) and those with intact perineum (9.4, SD = 4.9) (p-value <0.05). Lower levels of depression (−2.23 points on average) were significantly (p-value <0.05) associated with higher levels of perineum status (coded as 1 = episiotomy, 2 = other). Mothers who had a tear or episiotomy had on average 1.24 points higher EPDS scores compared to mothers with an intact perineum, although not significant (p-value >0.05). Conclusions: Policymakers and clinicians are recommended to consider following up mothers with adverse birth outcomes to outline the risk of developing postpartum depression, at the same time as they routinely screen all mothers for risk of postpartum depression during their postpartum visits.
