西安市学生中从膝部长骨干骺融合推算身高与年龄的回归方程

本文根据西安市2612名学生的活体测量和1361例的X线拍片观察,得出了应用膝部长骨的干骺融合程度及某些线性度量推算身高与年龄的三十个回归方程和相应的误差,同时,对得出的方程进行了讨论。

REGRESSION FORMULAE FOR ESTIMATING AGE AND STATURE FROM EPIPHYSEAL FUSION AND LINEAR MEASUREMENT

Based on the anthropometry of 2612 Han students and the observation of the ante-ro-posterior roentgengraph of the knee of 1361 students born in Xian, this paper provides thirty regression formulae for calculating age and from the degree of epiphyseal fusion in the long bones forming knee joint and some linear measurements.The estimation of stature from height of tibiale is considered as a better choice. The degree of epiphysis-diaphysis fusion on upper end of fibula is the better information for estimating age. The stepwise regression is suggestible rather than the linear.
