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 two sites (subscapular and triceps), in conjunction with nine body dimensions. For newborn infants total body fat so calculated accorded satisfactorily with published data from cadaver analyses. The formula has been tentatively applied to infants up to the age of 40 weeks, and to preterm infants. The difference between the growth of male and female infants was analysed 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.
