Breast-vs. bottle-feeding. A study of morbidity in upper middle class infants.

This study compares the morbidity of two groups of healthy, full-term infants (25 in each group) who were exclusively either bottle-fed or breast-fed for 5 months. There were no statistically significant differences in morbidity between the two groups except for a borderline greater frequency of upper respiratory infections in the bottle-fed group. Although the study groups are limited in size, the results suggest that, when appropriate hygienic measures are taken and statistical biases eliminated, differences in morbidity between bottle-fed and breast-fed babies are relatively minor. The data also show that modern infant formulas seem to be nutritionally complete in that there was no difference in the rate of growth or in hematological parameters measured in the bottle-fed and breast-fed group.

Results of feeding a special formula to very low birth weight infants.

Fifty-eight premature infants weighing less than 1,600 g at birth were fed a special formula. The formula contained nutrients in amounts recommended by the Committee ono Nutrition of the American Academy of Pediatrics for very low birth weight (VLBW) infants. The feeding studies were carried out at newborn nurseries in Tampa, Florida (study A, n = 25), Pittsburgh, Pennsylvania (study B, n = 20), and Oaklawn, Illinois (study C, n = 13). Study subjects were comparable in birth weight, gestational age, and in the duration of follow-up in the nurseries. All study subjects grew at rates of weight acquisition equivalent to the comparative fetal counterpart. Routine anthropometric measurements were similar to those of fetal development curves. Mean protein intake ranged from 2.3 to 3.7 g/kg/day and mean caloric intake from 105 to 150 kcal/kg/day. Late metabolic acidosis in association with prematurity was absent in all subjects studied as demonstrated by normal pH values, bicarbonate, and partial pressure of carbon dioxide. Serum sodium and serum chloride levels were normal. Serum calcium ranged from 8.3 to 10.1 mg/dl and serum phosphorus from 6.0 to 7.5 mg/dl. Total serum protein levels ranged from 4.5 to 5.1 g/dl. Blood urea nitrogen diminished progressively from 5.1 to 2 mg/dl in the course of the study. Serum glucose levels in samples taken prior to and 2 h after feeding did not demonstrate any evidence of reactive hypoglycemia.

L-carnitine supplementation of a soybean-based formula in early infancy: plasma and urine levels of carnitine and acylcarnitines.

The absence of carnitine in the diet of normal infants results in marked reduction of plasma carnitine levels. In order to evaluate the effects of L-carnitine supplementation of soybean formula, plasma and urine levels of free carnitine and acylcarnitine were compared in infants receiving carnitine-free soybean protein-based formula and the same formula supplemented with 50 and 250 nmol/ml L-carnitine. In infants receiving soybean formula with 50 nmol/ml L-carnitine, the plasma levels of free carnitine were not significantly different from those in infants receiving formula with 250 nmol/ml L-carnitine; however, urine levels of free carnitine were significantly increased when the infants received formula with 250 nmol/ml L-carnitine. In normal full-term infants, supplementation of soybean formula with 50 nmol/ml L-carnitine was sufficient to maintain normal plasma levels that were comparable to breast-fed infants.
