Maturity Status Norms for 11 And 12 Years Old Boys of Punjab Through Morphological Method.
Dr. Rajwinder Pal Singh,  Dr. Parminder kaur laroiya
The present study, conducted on 130 male children belonging to two age groups viz. 11 & 12 years, explores new avenues for anthropologists, sports scientists and physical trainers to find out the developmental age of children (below 20 years), just by taking five anthropometric measurements. These measurements for male children (separate for female) are body height(cm), body weight (Kg), biacromiale and billiospinale breadths (cm) and forearm circumference(cm.). the Body Development Index (B.D.I) of the child is obtained by using the formula given by Wutscherk (1982). the obtained value of B.D.I. is referred to the table to find out the developmental ages of the child. The developmental ages estimated for 11 and 12 years’ children of the present study show significant differences, that means, children of both these age categories are slow in their physical maturity. In the present study, hand wrist x-rays of children were also taken and assessment of development age by Tanner et al (1975) has also been made. A high level of correlation was observed between both these methods and there by claiming the stand for use of B.D.I. method to assess one’s developmental age. By making use of these methods i.e. TW2 20 – bone age method and B.D.I. method, the norms for assessment of developmental age for Indian children were made.
