由胸骨长度估算中国北方成年人身高的回归方程

调查了中国北方28具(男15、女13)汉族成年人尸体身高、胸骨全长、胸骨柄长和胸骨体长的均值,并计算了胸骨的长度与身高的相关系数。除男性胸骨全长高度相关外,其余皆为中度相关。由胸骨全长推算身高的回归方程式,较由胸骨柄长和胸骨体长推算身高的回归方程式,有较高的相关系数和较低的标准估计误差。由胸骨体长推算也较由胸骨柄长推算为佳。

ESTIMATION OF STATURE FROM STERNUM OF ADULTS IN NORTH CHINA

28 adult cadavers from north China were studied. The average value of the stature, the total length of sternum, the length of the manubrium sterni, the length of the body of sternum were measured. The coefficients of the correlation between the average length of the sternum and the stature were calculated. The coefficient of correlation between the total length of the ster-num, the length of the manubrium sterni, the length of the body of the sternum and the stature are 0.8630, 0.7122 and 0.8395 respectively. It shows that the correlation between them is rather high. But in the males the coefficients of correlation are 0.7157, 0.5789 and 0.5669 respective-ly; while in the females they are 0.6111, 0.5630 and 0.6122 respectively. Nine regression for-mulae from the average length of sternum and the stature were computed.The relationship between stature and total length of sternum reveals a higher coefficient of correlation and a lower standard error of estimation, as comparied to that between sta-ture and length of the manubrium sterni and that between stature and length of the body of the sternum. The reconstruction of stature from the length of the body appears more reliable than that from the length of the manubrium of the sternum.
