[Changes in the human fat mass from the ages of 6 to 18].
In 2,300 persons of both sex, 6, 8, 10, and 18 years of age, using the caliper of "Holtein"-type for measuring thickness of skin-fat folds, age dynamics in distribution of subcutaneous fat, as well as general, subcutaneous and internal fat have been estimated. Both in boys and girls at the age of 6-12 years the place of the greatest accumulation of the subcutaneous fat is the anterior surface of the femur; its least layer up to 10 years of age is localized on the brachium, and at the age of 12 and 18 years--on the forearm. The subcutaneous fat mass from 6 up to 12 years of age increases more than 3 times, while the body mass at the same time increases only by 91-98%. The most significant increment of the general fat mass is noted at 10-12 years of age. In 6-year-old children the part of the subcutaneous fat in the body mass is less than that of the internal fat. By 12 years of age the relative mass of the subcutaneous fat increases, and that of the internal fat remains practically the same. This, evidently, demonstrates that equilibrium between volumetric characteristics of tissues in the internal medium of the organism is preserved in the process of its age development. Up to 12 years of age sexual differences in the dynamics of all the parameters are insignificant. Comparing with the adolescents, in 18-year-old boys fat mass--body mass ratio decreases, and in the girls it continues to increase.(ABSTRACT TRUNCATED AT 250 WORDS)
