Nutritional balance studies: evaluation of a premature infant formula.
A 24 kcal/oz (81 kcal/100 ml) premature infant formula (Enfamil Premature Formula) with moderately high mineral content (117 mg Ca/100 ml and 58 mg P/100 ml) and a protein content of 3 g/100 kcal was evaluated in sixteen 3-day balance studies at 10 and 21 days of age in nine premature infants with birth weights from 1,200 to 1,400 g. Growth rates were similar to in utero rates, and the formula was well accepted and tolerated. Calcium retention (62.5%) was similar to in utero accretion, and phosphorus retention was only slightly lower. Nitrogen retention was high without the development of metabolic acidosis or abnormal serum urea nitrogen levels.
