Differences in subcutaneous fat in breast- and formula-fed infants.

During the first 6 weeks of life, 87 breast-fed infants had a significantly greater increase in skinfold thickness than 173 infants fed only with artificial milk formulae. The two groups were similar in respect of racial origin, gestational age, birthweight, and weight gain in the first 6 weeks of life. These findings show that formula-fed infants have a different distribution of body fat from breast-fed infants.
