By way of introduction to this workshop, I choose to speak on the nutritional individuality of affected population groups. In so doing, I view some results that are not so latent, and by placing these causes among other agents instrumental in deficits of growth and development of young children, I reflect on the manner and the extent to which they interact.
In developing countries where childhood malnutrition is common, most children are breast-fed. They do well for the first four months or so, with gains in height and weight comparable to children whose nutritional situation is more favorable. The difficulty comes with the beginning of weaning and continues until transition to an adult diet is completed, which in general is long postponed. The result is that the first two or three years of life are the critical period.
Older preschool children have usually proved easier to enlist in nutritional intervention
