Anthropometric standards vary among different populations, and renewal of these reference values is necessary.
To produce formulae for the assessment of limb segment lengths.
Whole-body dual-energy X-ray absorptiometry scans of 413 Caucasian children and adolescents (170 boys, 243 girls) aged from 6 to 18 years were retrospectively analysed. Body height and the lengths of four long bones (humerus, radius, femur and tibia) were measured. The validity (concurrent validity) and reproducibility (intraobserver reliability) of the measurement technique were tested.
High linear correlations (r > 0.9) were found between the mentioned five longitudinal measures. Corresponding linear regression equations for the most important relationships were derived. The tests of validity and reproducibility revealed a good degree of precision of the applied technique.
The reference formulae obtained from the analysis of whole-body DEXA scans will be useful for anthropologists, and forensic and nutrition specialists, as well as for prosthetists and paediatric orthopaedic surgeons.
人体测量标准在不同人群中存在差异，因此有必要更新这些参考值。
制定用于评估肢体节段长度的公式。
回顾性分析了413名6至18岁的白种儿童和青少年（170名男孩，243名女孩）的全身双能X线吸收法扫描结果。测量了身高以及四块长骨（肱骨、桡骨、股骨和胫骨）的长度。对测量技术的有效性（同时效度）和可重复性（观察者内信度）进行了测试。
在上述五项纵向测量之间发现了高度线性相关性（r > 0.9）。得出了最重要关系的相应线性回归方程。有效性和可重复性测试表明所应用技术具有良好的精度。
通过对全身DEXA扫描分析获得的参考公式，将对人类学家、法医和营养专家以及假肢师和小儿骨科医生有用。
