There is a different standard of growth and development for each region, population, ethnic community and for each period. So, this work was planned to study the anthropometric parameters and skeletal maturation of Egyptian children (in Sharkia) from 6 up to 16 years of age.Samples of 270 normal children living in Sharkia Governorate were chosen from different outpatient clinics in Zagazig University Hospitals . The children were classified into 9 age groups (6-7, 7-8, 8-9, 9-10, 10-11, 11-12, 12-13, 13-14, and 14-16 years). Each group included equal number(15) of males and females. Each of the studied children was subjected to various anthropometric measurements and skeletal maturity assessment.The anthropometric parameters used in this study were weight, height, BMI and triceps skin-fold thicknesses .The mean values and standard deviations of all parameters were presented in the form of tables and charts. The T test was done between the means of males and females as well as between successive age groups in both sexes. Correlation coefficients between the anthropometric parameters, and the skeletal age were assessed. Correlation coefficients between the anthropometric parameters were also assessed.The anthropometric measurements showed sexual differences where, the weight , height and BMI were found greater in male children than in females while, the skin fold thicknesses was greater in females than in males at younger age groups .As regards the height, the males were higher than females at the first 3 age groups then, the females became higher from the 4th to 7th year of age groups. Also the weight and BMI were greater in males than females in older age groups.With progress of age, some of the measured anthropometric parameters increased and the other decreased. The weight, height and BMI increased progressively from 6 years up to 13 years of age. On the other hand the skin fold thicknesses increased gradually with age progress after they have reached their peaks to reach the lowest level at the 14-16 years of age. The age at which they reached their peaks for the triceps skin fold thickness was at 6th age group in males and 7th age group in females .The weight had positive correlations with height, skin fold thickness and with BMI in both sexes.As regards the skeletal maturity guided by skeletal ages it was found that the skeletal age increased progressively in both sexes from 6 years up to 13 years of age. The males were advanced in their skeletal age from 6 months to 2 years of age. from 13-16 years of age, the females were advanced in their skeletal age than males.The mean bone ages for both sexes were more advanced than the mean chronological ages at all age groups .The mean bone age of both males and females at all age groups were above the 50th percentile of the American children .The skeletal age had positive correlations with weight, height and skin-fold thicknesses .
