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.
