Relationship of delayed lactogenesis II to maternal perception of insufficient milk: A longitudinal study

Abstract

AimTo analyze the relationship of delayed lactogenesis II with maternal perception of insufficient milk. MethodsA prospective, multicenter, longitudinal observational study was conducted. Data were obtained at discharge and between 1 and 5 months postpartum on the perception of insufficient milk and related variables, by means of a self-administered questionnaire, and subsequent postal and online follow-up. Logistic regression analysis was used to develop the explanatory model. ResultsA total of 260 puerperal mothers participated. Of these, 31.9% had insufficient milk and 23.6% had delayed lactogenesis II. During postpartum admission, delayed lactogenesis II (OR = 2.26; 95%CI = 1.07–4.79), difficulty in breastfeeding (OR = 1.02; 95%CI = 1.00–1.03), and professional help in breastfeeding (OR = 0.70; 95%CI = 0.50–0.97) were associated with maternal perception of insufficient milk. ConclusionsThe occurrence of breastfeeding difficulties during postpartum admission and at discharge, especially when there is delayed lactogenesis II, should be considered risk indicators, suggesting the need for additional support to standardized care. The PIM is a suitable indicator to assess the quality of professional breastfeeding support in improvement interventions.
