By measuring lengths of tibias and fibulas in computed radiography (CR) of living body, regression formulae for stature estimation were obtained from these measurements that were adapted to the population of northern adults of Han.
The length of tibias and fibulas were measured in radiography, including 422 subjects (207 men and 215 women). The body height of each subject was also recorded. Linear regression analysis between body height and the length of tibias and fibulas , analysis of variance of hypothesis test of linear regression model and t-test of the partial regression coefficient were applied to establish the regression equations for stature estimation. Then the paired t-test between the predictive value and the actual body height, the residual analysis, the tests of equal scedasticity and colinearity had been done to evaluate whether the equations accord with the model.
Thirty five regression equations which were statistical significant were obtained. The multiple correlation coefficient was from 0.909 to 0.823 and the standard error of the estimation was between 2.48-3.87 cm.
The lengths of tibias and fibulas on the CR films could be helpful to estimate stature. These equations could be used to estimate the body height of the Han population in North China.
通过测量活体计算机X线摄影（CR）中胫骨和腓骨的长度，从这些测量值中获得适用于北方汉族成年人的身高估计回归公式。
在X线摄影中测量422名受试者（207名男性和215名女性）的胫骨和腓骨长度，并记录每个受试者的身高。应用身高与胫骨和腓骨长度之间的线性回归分析、线性回归模型假设检验的方差分析以及偏回归系数的t检验来建立身高估计的回归方程。然后对预测值与实际身高进行配对t检验、残差分析、等方差性和共线性检验，以评估方程是否符合模型。
获得了35个具有统计学意义的回归方程。复相关系数在0.909至0.823之间，估计标准误差在2.48 - 3.87厘米之间。
CR片上的胫骨和腓骨长度有助于估计身高。这些方程可用于估计中国北方汉族人群的身高。
