世界卫生组织WHO根据骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度水平的丈量结果BMD与健康年轻人数据两者之间的规范差SD定出以下4项指标。

1正常：骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度在年轻人平均值的1SD内+1-1SD

2低骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度：骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度低于年轻人平均值12.5SD-1-2.5SD

一般说来，骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度每减少一个标准差值，无论用何种方法测定和在何处测定，都揭示今后发生骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松性骨">骨折的风险将增加约50%但在某一特定部位测得的骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度，对该处今后发生骨">骨折的风险预测作用，比在其他部位测定时要好。因此，较为明智的选择是较常发生骨">骨痛的部位检测骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度，或在已测得骨">骨量减少的部位定期复查骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度。科进骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度仪厂家提醒大家，如果出现有疑似骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松">骨">骨质">骨">骨质疏松的症状，要及时去医院做骨">骨密度">骨">骨密度">骨">骨密度">骨">骨密度测试并定期随访，从而判断有否骨">骨质">骨">骨质流失的情况发生，早发现早治疗。
