Dual-energy X-ray absorptiometry in the lumbar spine, proximal femur and distal radius in children

Abstract
Dual-energy X-ray absorptiometry was used to measure bone mineral density (BMD) in the lumbar spine, proximal femur and distal radius in 48 Japanese children aged 3–18 years. In the normal children (n=32), BMD increased with age in all locations, with a nearly twofold increase from preschool age to adolescence. Most of the children with chronic diseases known to affect vone metabolism (e.g., steroid osteoporosis) (n=16) had low BMD in every region, indicating that these disease states probably affect multiple sites of the skeleton in children.
