Assessment of total body fat in infancy from skinfold thickness measurements.

Abstract
A formula is given, allowing a value for total body fat to be calculated from skinfold thickness measurements at 2 sites (subscapular and triceps), in conjunction with 9 body dimensions. For newborn infants, total body fat so calculated accorded satisfactorily with published data from cadaver analyses. The formula was tentatively applied to infants up to the age of 40 wk and to preterm infants. The difference between the growth of male and female infants was analyzed in a series of 27 normal infants; the greater growth of musculoskeletal tissue in the male contrasted with the relatively greater growth of fat tissue in the female.
