A cohort study published recently in Revista Latino-Americana de Enfermagem evaluated breastfeeding self-efficacy, presence of postpartum depression symptoms and the association between breastfeeding self-efficacy and postpartum depression with cessation of exclusive breastfeeding. In all, 83 women were included in this study. Investigators used instruments like Breastfeeding Self-Efficacy Scale and the Edinburgh Postnatal Depression Scale. Statistical analysis was conducted using the log-rank tests, analysis of variance and the Cox survival model.Breastfeeding self-efficacy and postpartum depression did not reveal any statistical difference over time. The chances of cessation of exclusive breastfeeding were found to decrease by 48% when self-efficacy changed from low to medium and by 80% when it changed from medium to high. Postpartum women scoring ≥10 on the Edinburgh Postnatal Depression Scale discontinued exclusive breastfeeding, on average, 10 days earlier than those with a score ≤9, whose median breastfeeding duration was 38 days postpartum. Breastfeeding self-efficacy was thus found to be a protective factor for exclusive breastfeeding, while postpartum depression was a risk factor.
