Abstract

Introduction: There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs. Population and methos: Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for selfefficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded. Results: A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD]: ± 132.4) at 14 days and 285 mL (SD: ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were observed with biosocial variables. Conclusion: BMP was positively associated with breastfeeding self-efficacy; no association was observed with anxiety and depression among mothers of VLBWIs.
