The objective of this study was to derive regression formulae for stature estimation from long limb bones in a Japanese population. Moreover, commonly employed estimation equations, such as that of Fujii, were re-evaluated through application of current data. To construct equations, measurements were conducted on 434 living subjects (342 females and 92 males; 18-59years old). The whole or maximum length of the femur, tibia, and humerus was determined radiographically using dual-energy X-ray absorptiometry, which permitted measurement of long bones with no magnification. Regression formulae were constructed for females and males relative to the real body height measured in the erect position. Lower limbs of the femur and tibia were more accurate predictors (R=0.813-0.903) than the humerus was (R=0.670-0.708). Multiple regression models were produced for all three bones and the two leg bones, revealing no significant difference between R values. Comparison of these equations with those of earlier studies of Andou and Fujii verified differences in estimated stature, indicating that stature estimation formulae should be constructed based on current data obtained from precise physical measurements. These equations will benefit forensic anthropology and nutrition science for stature estimation of contemporary Japanese individuals.
本研究的目的是推导日本人群中根据长骨估算身高的回归公式。此外，通过应用当前数据对常用的估算方程，如藤井的方程，进行了重新评估。为构建方程，对434名活体受试者（342名女性和92名男性；年龄在18至59岁之间）进行了测量。使用双能X线吸收法通过影像学确定股骨、胫骨和肱骨的全长或最大长度，该方法允许在无放大的情况下测量长骨。针对女性和男性，相对于直立位测量的实际身高构建了回归公式。股骨和胫骨的下肢比肱骨是更准确的预测指标（R = 0.813 - 0.903），而肱骨的预测指标为（R = 0.670 - 0.708）。针对所有三块骨头以及两条腿骨构建了多元回归模型，结果显示R值之间无显著差异。将这些方程与安藤和藤井早期研究的方程进行比较，证实了估算身高存在差异，这表明应基于从精确身体测量中获得的当前数据构建身高估算公式。这些方程将有助于法医人类学和营养科学对当代日本人的身高进行估算。
