Research Interests

Dr. Dewey´s research area is community and international nutrition, with an emphasis on maternal and child nutrition. Current topics of investigation include:

1. Interventions to prevent malnutrition in developing countries (such as the use of lipid-based nutrient supplements), particularly among children under two and pregnant and lactating women
2. Iron status of infants and young children
3. Cross-cultural comparison of early lactation success and risk factors for breastfeeding difficulties
4. Influence of infant feeding practices on infant intake, growth and fatness, and subsequent risk of child overweight
