3術語和定義

下列術語和定義適用于本文件。

Z評分Z-score

實測值與參考人群中位數(shù)之差和參考人群標準差相比，所得比值即為Z評分。參考人群的Z評分數(shù)據(jù)

詳見附錄A、B。

4骨礦和骨骼肌質量發(fā)育狀況評價

骨礦發(fā)育狀況評價

根據(jù)3歲～17歲男、女童年齡別與身高別骨礦發(fā)育指標（包括全身去顱骨礦含量、全身去顱骨密度、

腰椎骨礦含量和腰椎骨密度）的參考值（附錄A），按照表1評價骨礦發(fā)育狀況。發(fā)育正常的兒童青少年，

使用男、女童年齡別骨礦發(fā)育參考值（附錄A表A.1～表A.8）；生長遲緩者（參考WS423-2013或WS/T

456-2014），使用男、女童身高別骨礦發(fā)育參考值（附錄A表A.9～表A.16）。不同骨礦發(fā)育指標的評

價結果不一致時，以最低Z評分評價結果為準。

骨骼肌質量發(fā)育狀況評價

根據(jù)3歲～17歲男、女童年齡別骨骼肌質量發(fā)育指標（包括四肢骨骼肌質量指數(shù)、四肢骨骼肌質量

百分比、上肢骨骼肌質量指數(shù)和下肢骨骼肌質量指數(shù)）的參考值（附錄B），按照表2評價骨骼肌質量發(fā)

育狀況。不同骨骼肌質量發(fā)育指標的評價結果不一致時，以最低Z評分評價結果為準。
