title: [Evaluation of bone mass in children in a national sample of the population].
abstract: Dual energy X-ray absorptiometry (DEXA) was used to measure a mean bone mineral density (BMD) and bone mineral content (BMC) in total body and lumbar spine (L2-L4--BMD; L2-L4--BMC) in a group of 306 healthy children of both sexes, aged between 6 and 18 years. Step-wise increase in BMD in peripubertal age was noted. A degree of an increase in BMD at the age of 10 and 16 years was higher in boys than in girls. Bone mineral density of the spine was lower in the Polish population than that in USA. A high degree correlation between densitometric measurements and calendar age, and body height and weight was noted.
