The creamatocrit, fat and energy concentration in human milk produced by mothers of preterm and term infants

Abstract

Objective: The objective of this study was to investigate the composition of breast milk which had been gathered from mothers for over first 2 weeks of lactation and to compare the changes in composition of preterm and term milk. Methods: A prospective, single center study was provided in Warsaw, Poland. The samples of breast milk from 22 mothers who had delivered prematurely and 39 mothers who had given birth to term infants were collected. The creamatocrit, energy and fat concentration were estimated in each participant’s breast milk sample twice a day (morning and night hours). Results: The lowest creamatocrit, calories and fat concentration was indicated in the preterm milk obtained in the morning (4.86%, 663.8 kcal/L and 33.6 g/L, respectively). The highest milk parameters were observed in the night samples of full-term milk and measured (9.6%, 919.7 kcal/L, and 60.7 g/L, respectively). No significant differences in analysed parameters were observed between preterm and full-term milk (p > 0.05). In summary, creamatocrit, calories and lipid concentration in breast milk shows the daily differences. Colostrum and mature milk from mothers of preterm neonates differed from colostum and mature milk from mothers of term neonates. They had lipid contents, creamatocrit level and calorific value.
