Fracture Prediction and the Definition of Osteoporosis in Children and Adolescents: The ISCD 2007 Pediatric Official Positions

Osteoporosis in adults has been defined on the basis of densitometric criteria, but at present the term osteoporosis does not have a widely recognized definition in pediatrics. Consequently, the International Society for Clinical Densitometry (ISCD) 2007 Position Development Conference reviewed the literature describing the relationship between bone densitometric studies and fractures in apparently healthy children and adolescents, and prepared Official Positions regarding the definition of osteoporosis in children and adolescents. The ISCD Official Positions with respect to the above issues, as well as the rationale and evidence used to derive these positions, are presented here.
