The present study comprised of 1155 Soliga tribal boys ranging in age group of 8 to 18 years from Chamarajanagar, Coorg and Mysore districts of Karnataka. 12 measurements were included in the present cross sectional data. The segmental growth progression of the body assessed through percentage of growth at each age from 8 to 18 years related to their final size attained at 18 years. The growth spurt was observed for trunk height, leg length, and foot length at 13 years, while for the stature, sitting height, neck length, total upper extremities length, hand length, upper arm length, forearm length, total lower extremity length, thigh length at 15 ­ 16 years. The growth of constituent components of upper and lower extremity at all ages showed caudo­cephalic sequence of maturation. However the growth of upper arm, thigh gradient showed cephalo­caudal as well as caudo­cephalic sequence of maturation.
