CTRC Nutrition Core, Nutrition Assessment (CHOP)

Director: Zemel, Babette, PhD (CHOP)

Summary:

The Nutrition Assessment Unit of the Nutrition Core is a state-of-the-art facility for the assessment of growth and body dimensions, body composition (the amount of muscle, fat and bone in the body), energy expenditure, bone density, and muscle strength. The Unit has two locations and four experienced technicians for performing research assessments.
