Infant feeding and subcutaneous fat at birth and at one year

Abstract

Skin folds were measured at birth and at 1 year in infants who were obese, normal or thin at birth, infants of obese mothers and infants of diabetic mothers. There was no significant correlation between skinfold thickness at birth and skinfold thickness at 1 year and there was no significant difference in skinfold thickness between any of the groups at 1 year of age. These findings are not consistent with the hypothesis that overnutrition in the last 10 weeks of pregnancy has a permanent effect on the adiposity of the infant. The distributions of triceps and subscapular skinfolds in these 1-year-old infants were considerably lower than in a 1967-68 survey of British 1-year-olds. In this (1976) survey, the breast-feeding rate (40% at 2 months) and the mean age of introduction of solids (15 weeks) were both greater than in previous British surveys. Recent warnings against overfeeding in infancy may be changing feeding practices, resulting in slimmer 1-year-old children.
