摘要： 目的应用计算机X线摄影(computer radiography,CR)测量活体胫腓骨长度,建立适合当代中国北方汉族人群胫腓骨长度推算身高的数学模型。方法在422例(男性207例,女性215例)活体山东汉族成年人的胫腓骨正位CR片上测量5项长度指标,同时测量其身高。通过各项测量指标与身高的线性回归分析、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,建立运用胫腓骨长度推算身高的回归方程;并对所建立的方程进行身高预测值与真实值的配对t检验、残差分析等方程的预测与诊断。结果共建立有统计学意义的一元回归方程35个。所建立的回归方程的相关系数在0.909～0.823范围内,回归方程的估计值标准误在2.48～3.87cm范围。结论应用CR放射学方法测量胫腓骨长度推算身高,可以为法医学个人识别身高推算提供帮助,建立的回归方程适用于中国北方汉族人群胫腓骨的身高推算。

Abstract: Objective 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.Methods 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.Results 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 2.48-3.87cm.Conclusion 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.
