Abstract
In order to identify as early as possible those children who may later develop malnutrition, a sample of Zambian copper-miners' children of known age and birth weights were measured at the age of one year and again at 18 months. By this time, their mean weight, height, triceps skin-fold, arm circumference and developmental progress were less than expected and many were, or had been ill, with malnutrition and infections. The slower growth corresponded significantly with lower development scores.
