THE INTEREST in body composition during growth, particularly as reflected in studies of obesity, has accelerated in the past few decades so that many different disciplines are being utilized in current studies. The symposium on body composition reported in the Annals of the New York Academy of Sciences1 in 1963 is evidence for the variety of the different paths of investigation extant at this time. Since no single method of study enables one to determine the proportion of weight that is made up of the growing skeleton, the muscle mass, and the adipose tissue of the individual child at successive ages, this longitudinal study of tissue measurements from seriatim measurements from roentgenograms seems to add to our understanding of the variations in body composition that occur during growth in healthy boys and girls.

The measurement of bone, muscle, and fat shadows from roentgenograms of the child was first reported
