通过单光子吸收法，测量了１０５名健康学生桡、尺骨中、远１／３交界处的骨密度。结果表明。年龄与骨矿含量呈正相关，男性骨量增加的速率大于女性；在１７岁以后男性骨量明显高于女性，有显著性差异；骨量与身高、体重呈直线正相关。 One-photon absorption method was used to measure the bone mineral density of 105 healthy students in the radial, ulnar and distal 1/3 junction. The results show. There was a positive correlation between age and bone mineral content. The rate of bone mass increase was higher in males than in females. The bone mass of males was significantly higher than that of females after 17 years old. There was a linear positive correlation between bone mass and height and body weight.
