Overview

abstract

  • Background Mothers of preterm (PT) infants have difficulty providing adequate quantities of human milk (HM) for their babies during their hospital stay. The macronutrient content in HM changes over time, varying across and within individual mothers. The research aim of the strudy was to describe the intake of mothers' own milk (MOM) and its composition according to gestational (GA) and postnatal age (PNA) in infants born <32 weeks' GA and to correlate them with neonatal weight, length and morbidities. Methods A prospective observational study of 176 premature infants in a unit without a donor milk bank was conducted. Daily milk intake was recorded. HM macronutrients were determined by mid-infrared spectrophotometric analysis at 7, 15 and 30 days after delivery and monthly until hospital discharge. Results Intake of MOM increased during the first 2 weeks after birth and decreased steadily thereafter. Protein concentration varied inversely with PNA. Carbohydrate and lipid concentrations increased over the first few days and remained stable thereafter. A fall in weight percentiles from birth to 60 days was found. No correlation was found between total protein and calorie intakes at 3 and 15 days of life and growth velocity (GV) between 15 and 30 days, even when broken down into parenteral nutrition (PN), formula and MOM. Conclusion To improve MOM feeding in PT newborns, intensive support strategies at the prenatal stage along entire hospitalization income should be encouraged. New protocols for fortification of HM should be implemented to optimize postnatal weight gain while preserving the health benefits of HM.
