title: The influence of some socio-demographic factors on body weight and stature of 6-18 years old boys from Cairo, Egypt.
abstract: Body weight and stature have been studied in a cross-sectional sample of 926 Egyptian boys aged 6-18 in relation to age, level of education of parents, sibship size and order of birth. The results show that education of either parent has obvious influence on body weight and to a lesser extent on stature. The impact of parental level of education on both characters is particularly significant, if the two parents are equally educated or not. The boys of smaller sibship size (3 or less) have heavier weight and taller stature than those of bigger sibship size (4 or more sibs). There is no consistancy in the relationship between birth order and either weight or stature. Body weight, however, is heavier for the first and second child than for the later children. Nevertheless, boys of any of the four studied categories (first, second, third, and fourth or more child) might be the tallest in one age group and the shortest in another.
