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.
采用双能X线吸收法（DEXA）测量了306名6至18岁的健康男女儿童的全身及腰椎（L2-L4——骨密度；L2-L4——骨矿物质含量）的平均骨密度（BMD）和骨矿物质含量（BMC）。观察到青春期前年龄阶段骨密度呈逐步增加。10岁和16岁时男孩的骨密度增加程度高于女孩。波兰人群的脊柱骨密度低于美国人群。观察到骨密度测量值与实际年龄、身高和体重之间存在高度相关性。
