Longitudinal study of growth and development of young Jamaican children recovering from severe protein-energy malnutrition.

The developmental level and nutritional status of a group of 17 children aged between six and 24 months who were admitted to hospital with severe protein-energy malnutrition were studied from admission to hospital until 36 months after returning home. They were compared with a group of 14 adequately nourished children of similar age who had been admitted to hospital for other reasons. Initially the malnourished group were markedly behind the controls in developmental level, and they failed to reduce their deficit in hospital. Over the following 36 months they showed a gradual improvement relative to the controls in developmental level, height and head circumference, but were still significantly behind at the end of the study. In contrast, they caught up in weight for height by one month after returning home. When length of stay in hospital, age at admission, birthweight, mother's IQ and home background measures were taken into account, the direction of the differences between the two groups and significance levels were unchanged.
