Calcium and bone metabolism; establishing nutrient requirements; calcium metabolism during lactation; bone mineral acquisition in children

Heidi Kalkwarf, PhD, RD, is a nutritional epidemiologist whose research interest is in the development of dietary recommendations to optimize health, particularly bone health.

She has conducted research, funded by the National Institutes of Health (NIH) and the United States Department of Agriculture (USDA), focusing on dietary calcium requirements of lactating women and the changes in bone density and in calcium metabolism that occur during lactation and after weaning. Dr. Kalkwarf's research has been published in the New England Journal of Medicine, and was used by the Institute of Medicine to establish the new dietary calcium intake recommendations for lactating women.

Dr. Kalkwarf also is investigating the normal patterns of bone growth and development in children and adolescents. The goals of this work are to identify the short term and long term consequences of low bone density in childhood, identify children who are at risk for osteoporosis later in life and to identify interventions to reduce this risk.

Dr. Kalkwarf came to Cincinnati Children's Hospital Medical Center as a postdoctoral fellow in 1990 and joined the faculty in 1993. She earned her master's and doctoral degrees in nutritional sciences at Cornell University in Ithaca, NY.
