About Me

Biography

Heidi Kalkwarf, PhD, RD, is a nutritional epidemiologist whose research interest is in bone health and body composition development during growth. Her research investigates the normal patterns of bone acquisition in infants, children and adolescents, how lifestyle factors and chronic medical conditions affect bone accrual and how bone mineral deficits translate to risk of fracture. The long term goals of this work are to identify children who are at risk for fractures in childhood or osteoporosis later in life and to identify interventions to reduce this risk. One of her current studies focuses on bone acquisition in toddlers and pre-school aged children, an understudied population that is undergoing rapid changes in motor skills, physical activity, dietary intake and growth. She is also investigating the long term bone health consequences of bariatric surgery performed during adolescence. Dr. Kalkwarf’s research has been funded by the National Institutes of Health for the last two decades.

Dr. Kalkwarf is a standing member of the NIH study section Neurological, Aging and Musculoskeletal Epidemiology (NAME). She came to Cincinnati Children's Hospital Medical Center as a postdoctoral fellow in 1990 and joined the faculty in 1993.
