Height and weight measurements of male Turkish adolescents according to biological maturation.

Abstract

Eight hundred and seventy-nine Turkish male adolescents aged between 11 and 19 years were investigated with respect to their physical development. Bone ages were considered as well as chronological ages in determining biacromial (BAC), biiliac lengths (BIC) and chest circumference (CC). Different bone and chronological ages were obtained at the same chronological age (CA) and bone age (BA) columns. The importance of bone ages in evaluating an adolescent's physical development was shown to be as important as the chronological ages. In this study, the mean BAC, BIC and CC values between the same CA but different BA groups showed statistically significant differences (P < 0.001). When the measurements of two consecutive age groups who had the same CA and BA and who were found to be statistically significant (P < 0.05) were compared, the maximum increments in BAC and BIC values which were between 13 and 14 years of age (2 and 1.4 cm, respectively) were similar to the maximum increment in height and weight of Turkish male adolescents found between 13 and 14 years of BA. The maximum increment in CC values which were between 14 and 15 years and 15 and 16 years (4.1 cm each) was 1 year after the maximum increment in height and weight for BA of Turkish male adolescents (13-14 years) and was similar to maximum weight increment for CA which was between 15 and 16 years.
