Pediatric Growth and Nutrition Branch (PGNB)

Hand under X-RayOverview/Mission

PGNB serves as the focal point for NICHD extramural research in pediatric endocrinology and nutrition and their impact on health promotion and disease prevention throughout the life course. PGNB also serves as the focal point for NICHD training in child health research.

Specifically, PGNB supports research to understand the relevant biological systems and factors that influence the mechanisms of physical and neurological development beginning in utero and extending through the lifespan, as well as the role and impact of nutritional status in these systems; the branch also encourages research to explore the external contextual (social, behavioral, and environmental) factors that influence these processes.

PGNB further supports translational and systems-based research in the application of behavioral, medical, and nutritional science to develop interventions aimed at promoting health and mitigating disease during critical periods in human development.


  • Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN) Project: This effort by federal and non-federal partners and extramural investigators, led by PGNB, examines the ecology of human milk and its functional implications for both lactating parent and infant.
  • The Determinants of Peak Bone Mass: A State of the Science Workshop was co-sponsored by PGNB, the NIH Office of Research on Women's Health, the NIH Office of Dietary Supplements, the National Osteoporosis Foundation, and the American Society for Bone and Mineral Research. The proceedings are available in the Journal of Pediatrics.
