ABSTRACT
OBJECTIVES:
To establish a mathematical model of stature estimation for Sichuan Han females on the basis of the relationship between lower limbs and individual height, thus to provide evidence for forensic identification.METHODS:
Samples were collected from 171 Sichuan Han females. Large flat panel multi-function digital photography system was used to take the full-body X-ray films of the lower limbs. Indexes of long bones and stature of the subjects were measured, respectively. A linear regression analysis was carried out on the correlation between them, and a mathematical model of the stature calculation was established. Then the mathematical model was used to calculate the stature of another 29 Sichuan Han females to test its accuracy.RESULTS:
The maximum length of femur ï¼x1ï¼ had the highest correlation with stature. A total of 13 linear regression equations were established ï¼P<0.05ï¼, with the correlation coefficient ï¼Rï¼ 0.821-0.897 and the standard error of the estimation ï¼SEEï¼ 2.994-3.812 cm. The backtesting showed that the equation y=41.604+1.205 x1+1.318 x6+2.444 x12+1.852 x13-2.388 x14 had the smallest mean absolute deviation ï¼2.485 years oldï¼ and the highest accuracy of ±2SEE ï¼92.9%ï¼, and that the equation y=48.783+2.568 x1 had the highest accuracy of ±1SEE ï¼60.7%ï¼.CONCLUSIONS:
The stature estimation is high by using the long bones of the lower limbs has high accuracy.Palabras clave
