    Children During Adolescence [10 - 16 Years]

the development in all the bones i.e. Radius, Ulna, Short bones and Carpal bones it shows intermediate values between RUS and Carpal bones.

The trends of skeletal maturity are the same for both Delhi and Jabalpur boys and girls except that they lag behind by 6-12 months at several chronological ages. The plotting of percentile values of skeletal maturity scores for Vellore boys and girls shown in Fig. 50 to 55, on the reference graphs published for British children by Tanner shows that they compare very well with British children at each age group. However, each centre shows some divergence. For example, in Vellore children, the variation as reflected by the 3rd and 97th percentiles is more for each of the bone scores at all ages considered. The picture is not very different for boys and girls from other two centres except that the 50th centile values of all the three skeletal maturity scores coincide with 25th centile of the reference population till the age of 13 years. From then onwards there is a close agreement between the 50th centiles. In general the variability is more for Delhi and Jabalpur children for each of the skeletal maturity scores.


This longitudinal study was carried out in six centres to study the physical growth, secondary sexual characteristics and skeletal maturity during adolescence as well as to study the growth and development in relation to previous nutritional status. A total of 6829 children (3517 boys and 3312 girls) in the age group of 10 to 12 years were followed up at six monthly intervals for a period of five years. The anthropometric parameters of physical growth studied were height, weight, chest circumference, mid-arm circumference, bi-acromial diameter and bi-cristal diameter. The centrewise average values, standard deviations and percentiles for males and females are presented in Tables 2 to 17..

No significant differences in height and weight were observed in this study as compared to an earlier ICMR study conducted in the seventies 5.

The mean height of males was 6.1 cms. and 12.9 cms. lower for rural areas and 5.6 cms. and 6.5 cms. for urban areas studied than the mean height of affluent Indian children at 10 years and 16 years of age respectively. With regard to weight of male children this difference was 5.9 and 5.1 kgs. respectively at 10 years of age and 16.0 and
