Association between maternal satisfaction with breastfeeding and postpartum depression symptoms

Due to the multiple health benefits of breastfeeding, it is essential to identify factors that may negatively interfere with this healthy practice. Among such factors are postpartum depression (PPD) and maternal satisfaction with breastfeeding. The objective of this study was to evaluate the association between maternal satisfaction with breastfeeding and symptoms of PPD in the first month after childbirth.

This cross-sectional study nested in a cohort study was conducted in Porto Alegre, Brazil, with 287 puerperal women selected at two maternity hospitals, one public and one private. Women were interviewed at their homes the week after the infant completed 30 days of life. A structured questionnaire was applied, as well as instruments to evaluate maternal satisfaction with breastfeeding (Maternal Breastfeeding Evaluation Scale) and to screen for PPD (Edinburgh Postnatal Depression Scale). The association between higher satisfaction with breastfeeding (outcome) and negative PPD screening test was assessed using Poisson regression with robust variance, adjusting for specific covariables. Adjusted prevalence ratios (aPR) and respective 95% confidence intervals (95%CI) were estimated.

The prevalence of increased satisfaction with breastfeeding (defined as women with scores above the median) was 47% higher among women who screened negative for PPD when compared to those with a positive result (aPR 1.47; 95%CI 1.01-2.16). This result was adjusted for maternal age and skin color, cohabitation with the infant's father, planned pregnancy, type of delivery, exclusive breastfeeding, and occurrence of breastfeeding problems.

The findings of this study showed an association between higher maternal satisfaction with breastfeeding and absence of PPD symptoms, reinforcing the importance of caring for the mental health of pregnant and puerperal women and paying attention to their satisfaction with breastfeeding.
