Abstract
The concentrations of protein nitrogen (PN), non-PN (NPN), energy (Cal), fat (F), sodium (Na), calcium (Ca), phosphorus (P), magnesium (Mg), and zinc (Zn) were determined in human milk from mothers giving birth to infants classified as preterm appropriate-for-gestational age (PAGA, n=5); preterm small-for-gestational age (PSGA, n=4); term AGA (TAGA, n=5); and term SGA (TSGA, n=6). Samples were collected under controlled conditions at 2 week intervals for 12 weeks postpartum. PN concentrations did not differ significantly except between PSGA and TSGA. Overall PN means were 206 and 157 mg%, respectively. No other differences in nutrient concentration were observed between the 4 groups. Concentrations of PN, NPN, Na, P, and Zn decreased over time. The concentration of Mg increased slightly. The content of F, Cal, and Ca did not change. These data indicate that the concentrations of some potentially limiting nutrients do not differ in milk from mothers delivering tell and preterm infants.
