Dr. Barffour’s broad research interests involve the epidemiology and reduction of morbidity and mortality among women and pediatric populations in resource-poor regions. His primary research focuses on the bidirectional interactions between infections and micronutrient status
Specific interests include (a) childhood malaria risk as a function iron status or supplementation; (b) effects of preventive and therapeutic zinc interventions on growth, immune response and diarrheal outcomes in children; (c) vitamin A supplementation and health outcomes in women and children; (d) anemia reduction through integrated malaria-iron strategies; (e) inflammation-associated changes in the biomarkers of micronutrient status; and (f) validation of the Portable Field Dark Adaptometer for measuring functional vitamin A status.
