Nutritional intervention: a key to child survival.

In a collaborative relationship, researchers from the Cebu Institute of Medicine and from the United States have carried out a series of longitudinal studies of breast feeding and infant growth in a rural Philippine community. On the basis of our findings, we have conducted field experiments designed to have mothers improve their infants' diets using locally available food. Contingent reinforcement strategies were used successfully to get mothers to change their behavior and beliefs about infant feeding practices. The use of reinforcements resulted in improved diets and very high rates of continuation of participation in the field experiments. We believe that this is a highly productive and cost effective way to approach the problem of gaining cooperation and continued involvement in a nutrition intervention effort.
