Bone mineral density and body composition in normal weight, overweight and obese children.

Background: There is a possibility that excess body fat affects bone mass gain and may compromise skeletal health in obese children. The purpose of the study was to identify the relationship between bone mineral density (BMD) and body composition in normal weight, overweight and obese children.

Methods: This was a cross-sectional study of 6- to 11-year-old children who attended the hospital's outpatient clinic.
