Urban-rural differences in the growth of Peruvian children.
The growth characteristics of children from four villages in northern Peru were compared with those of poor urban children in the capital city, in whom short stature but generally satisfactory weight for height relationships after infancy had been demonstrated. Height for age and weight for age fell more rapidly during infancy in the rural than in the urban children of both sexes. Rural girls caught up with the urban girls in height during childhood but did not match them in weight until late adolescence. Their weight to height ratios were consistently lower after 1 year of age, most strikingly between 2 and 5 years of age, and did not approach or match those of the urban girls until adolescence. Rural boys did not catch up with the urban boys in height or weight (differences in height were not statistically significant between 6 and 10 years, however) and their ratios remained consistently lower until late adolescence, most strikingly in early childhood and during puberty. Such urban-rural and sex differences, if typical and current, might well call for very different remedial measures at different ages in each of the populations.
