Abstract

A child's growth achievement depends on his genetic endowment and the environment in which he lives; Comparative studies of children of similar racial origin but growing under different environmental conditions have shown differences in their body size and shape. In general higher income families produce offspring with higher mean birth weight. This is largely due to better nutrition and care of mothers during pregnancy and childhood. Children from higher socioeconomic groups are on an average larger in size in terms of weight, height, head circumference, midarm circumference, crown-rump length and leg length. This is largely due to a better home environment including sanitation, nutrition, health and care enjoyed by the better-off children. .Generally urban children are larger than rural children mainly due to economic differences between the two areas. In most countries the secular trend to children getting larger still continues reflecting an improvement of living conditions with time. Unlike body size, body shape is less influenced by the environment and the change in body proportion brought about by environment is not permanent. In developing countries, children from higher socioeconomic families have generally thicker skinfolds. On the average, infants and preschool children of European ancestry have thicker triceps skinfolds compared with Negroes and Asians living in comparable environments. It is possible that this is due to long term adaptation to different climatic conditions.
