Overview/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.
The branch supports research to understand the relevant biological systems and factors that influence 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. PGNB also encourages research to explore the external contextual (social, behavioral, and environmental) factors that influence these processes.
Furthermore, PGNB supports translational and systems-based research in the application of behavioral science, medical science, and nutrition science to develop interventions for promoting health and mitigating disease during critical periods in human development.
- Bone Mineral Density in Childhood Study (BMDCS) (Historical/For Reference Only): This multicenter study, supported by NICHD from 2001 to 2011, identified predictors of the timing and magnitude of peak bone mass, a major determinant of osteoporosis in later adulthood. Comparable to the Centers for Disease Control and Prevention growth curves for children and adolescents, the BMDCS developed reference curves for bone mineral density, bone accrual, and linear growth velocities to serve as a valuable tool for both clinicians and investigators worldwide. Data are available in NICHD’s Data and Specimen Hub (DASH).
- Child Health and Development Study (CHDS): The CHDS began in 1959 as a companion to the Collaborative Perinatal Study and includes data on more than 20,000 pregnancies. CHDS data are particularly relevant for investigators studying maternal and placental origins of disease, especially the long-term effects of in utero exposure to organochlorines, such as DDT. Data are available in NICHD’s DASH.
- Fels Longitudinal Study
: This large study began in 1929 to evaluate human growth and body composition changes over the lifespan. NICHD funded data collection on more than 1,400 individuals enrolled at birth. The North American Standard Tables of Height and Weight and other standards of bone age and skeletal development used Fels data and are in widespread use in the United States and abroad. - Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) Study PubMed Articles: These scientific articles resulted from the HAPO study, partially funded by PGNB.
- National Collaborative on Childhood Obesity Research (NCCOR) : This collaborative effort focuses on accelerating progress to reduce childhood obesity in America, especially among high-risk populations and communities. NCCOR provides a library of internal resources as well as online tools such as the Measures Registry, the Catalogue of Surveillance Systems, and the Youth Compendium of Physical Activities, which may be useful for investigators studying childhood obesity. NICHD is an NCCOR member and has contributed to the development of these materials.

Highlights
- ADVANTAGE (Agriculture and Diet: Value Added for Nutrition, Translation, and Adaptation in a Global Ecology) Project Virtual Meetings. In spring 2023, PGNB sponsored this series of working group meetings to better understand the intersection of food systems, diet, nutrition, and health.
- Biomarkers of Nutrition for Development–Knowledge Indicating Dietary Sufficiency (BOND-KIDS) Working Group Meetings. In 2022, PGNB sponsored this series of working group meetings to examine the nutritional needs and assessment issues for school-age children (5 through 19 years). Visit the meeting page to access recordings of all four working group discussions.
- BEGIN Project Webinar Series. In early 2021, PGNB sponsored a series of meetings to examine the ecology of human milk and its functional implications for both lactating parent and infant. Visit the meeting page to access recordings of all five working group discussions.
- The American Journal of Clinical Nutrition recently published a supplement about the BEGIN Project .

- Exploring the Science Surrounding the Safe Use of Bioactive Ingredients in Infant Formula: Considerations for an Assessment Framework. In fall 2021, PGNB collaborated with the U.S. Food and Drug Administration (FDA) to sponsor a 2-day workshop focused on the functional state-of-the-science of biologically active human milk components and analogs and the implications for safety assessments when used in infant formula. Access the recordings from Day 1 and Day 2.
- Bridging the Biological and Communication Sciences on Nutrients and Environmental Contaminants in Foods to Support Child Development. In early 2023, PGNB, in collaboration with the FDA, sponsored a 2-day workshop focusing on research in risk communication, environmental contaminants in food, and the role of nutrition as they relate to child development. Access the recordings from Day 1 and Day 2.
