Abstract -1- INTRODUCTION AND AIM OF THE WORK - Growth studies provide a means of monitoring developmental plasticity and are important in evaluating the impact of environmental stress (Buschange et al., 1983). Waston, 1967, Son’a and others 1990, stated that growth of young children is an extremely sensitive indicator of the general state of their health and any adverse changes in the environment can disturb growth .- before or without any clinically diagnostable disease. Association between physical growth and mental development has interested many scholars in the field (Tanner, 1969. Tanner, 1978, Lasky et al., 1981, Pollitte eta!., 1982 and Ounsted et al., 1988). However, the human growth is not a steady uniform process all over the growth period but certain periods are characterized by marked change in rate and increment of growth e.g pubertal growth spurt. Nevertheless, in the man’s medical and social heritage the age of 7 years constitute special interest in marking between periods of growth. The ancient Greeks classify the human growth into stages each of 7 y. period |
