用商用双光子骨密度仪测定了136名1~18岁正常生长儿童腰椎(L2~L4)的骨矿含量(BMC)。BMC计算为BML(单位长度的BMC)和BMD(单位表面积的BMC)。儿童腰椎骨矿含量(2.53+/-0.86GHA/cm)显著低于成人(4.26+/-0.57GHA/cm)。腰椎BMC无性别差异。BML和BMD高度依赖于年龄、身高和体重。在青春期前几年，BML和BMD呈直线增长。在青春期，BMC增加更快：BMD增加40%，BML增加77%。对于整个人群，BMC随年龄、身高和体重的增加通过指数回归线分析得到了最好的预测。
In 136 normal growing children between the ages of 1 and 18 yr, bone mineral content (BMC) at the level of the lumbar spine (L2-L4) was determined with a commercial dual-photon absorptiometer. BMC was calculated as BML (BMC per unit length) and BMD (BMC per unit surface). The mean lumbar spine BML of the studied children (2.53 +/- 0.86 gHA/cm) was significantly lower than the spinal mineral content of adults (4.26 +/- 0.57 gHA/cm). No sex difference existed in lumbar spine BMC. BML as well as BMD were highly dependent on age, body height, and body weight. During the prepubertal years, BML and BMD increased in a fairly rectilinear pattern. During puberty, BMC increased more rapidly: 40% for BMD and 77% for BML. For the entire group, the increase in BMC with age, height, and weight was best predicted by an exponential regression line analysis.
