Abstract
Growth is marked by changes in body shape as well as increase in body size. It is suggested that changes in body shape in childhood and adolescence be analyzed by least squares fit lines for one dimension on a second at successive ages. These are preferred during childhood to the traditional indices of anthropologists because body proportions change with growth, and one can identify the direction of the change and observe which body dimension is changing, or if both are. Furthermore, populations may be compared by analysis of covariance for different patterns of growth related to sex and ethnic groups. Analysis of a number of populations have demonstrated clear differences between the sexes and between populations for the following body proportions: sitting height to leg length, arm length to leg length, biacromial width to biiliac width.
