【摘要】：目的测量颈椎高度建立四川汉族女性人群的身高推算方程,为法医学个人识别提供帮助。方法应用计算机X线摄影放射学方法,在209例四川汉族女性颈椎CR片上测量C3～C7椎体高度,并准确测量身高。按年龄是否大于45岁进行分组,对各颈椎的测量数据与身高进行线性回归分析,建立颈椎推算身高的回归方程。结果共建立一元回归方程36个,多元回归方程12个,所有回归方程经线性回归模型假设检验,均有统计学意义(P0.05)。所建立的回归方程的复相关系数(r)在0.628～0.280范围内,回归方程的标准误在4.03～5.03cm范围内。结论本研究所建立的回归方程,可用于四川汉族女性颈椎的身高推算。
[Abstract]:Objective to measure the height of cervical vertebrae and establish the equation of height calculation for the female population of Sichuan Han nationality so as to provide help for personal identification in forensic medicine. Methods the height and height of C3~C7 vertebrae were measured on the CR film of the cervical vertebrae of 209 women of Han nationality in Sichuan province by computer radiography. According to whether the age is more than 45 years old, the linear regression analysis of the measured data and height of each cervical vertebra is carried out, and the regression equation for calculating the height of cervical vertebrae is established. Results A total of 36 single regression equations and 12 multivariate regression equations were established. All regression equations were tested by linear regression model and were statistically significant (P0.05). The complex correlation coefficient (r) of the established regression equation is in the range of 0.6280.280, and the standard error of the regression equation is in the range of 4.03~5.03cm. Conclusion the regression equation established in this study can be used to calculate the height of cervical vertebrae in Sichuan Han women.
