A Positive Deviance/Hearth Nutrition Program (PD/Hearth) is a home- and neighborhood-based nutrition program for children who are at risk for protein-energy malnutrition in developing countries. The program uses the “positive deviance” approach to identify those behaviors practiced by the mothers or caretakers of well-nourished children from low-resource families and to transfer such positive practices to others in the community with malnourished children. The “hearth” or home is the location for the nutrition education and rehabilitation sessions.
