中国汉族成人胸骨多项测量值与身高关系的研究

目的 研究中国汉族成人胸骨多项测量值与身高的关系,建立以胸骨推算身高的方法。方法 测量135例(男100,女35)已知身高的中国汉族成年人干燥胸骨的全长、柄长、体长、柄最大宽、柄最小宽、体最大宽、体最大厚、柄厚、柄最大厚9项指标,采用多元逐步回归分析的方法,分别求出由男性(分年龄组)和女性胸骨的多项测量值推算身高的多元回归方程式。结果 所建立的4个男性(分年龄组)和1个女性胸骨推算身高的多元回归方程式,其复相关系数(R)在0.6237～0.7350之间,标准差(s)在4.5720—7.0348之间。结论 根据人体胸骨的多项测量值可以推算其身高,准确性略低于四肢长骨的同类推算;相同身高组的男女性胸骨多项测量值均存在明显的性别差异,胸骨柄长不能作为单因素推算身高的测量指标。

A study of the relationship between the adult sternum multiple measurements and the body length in Chinese Han population

Objective To study the relationship between the adult sternum multiple measurements and the body length in Chinese Han population for the purpose of body length estimation. Methods In this article, we had surveyed 135 samples(100 males and 35 females) .The total length of the sternum, the length of the sternal manubrium and the sternal body, the maximum and minimum breadth of the sternal manubrium, the Kleinste Breite des Ma-nubrium sterni, the maximum breadth of the sternal body, the Dicke des Manubrium sterni, the thickness of the sternal manubrium,the maximum thickness of the sternal manubrium and the sternal body in Chinese Han population was measured. Multiple linear regressions for estimating the body length were obtained by the stepwise regressive mathematics. Results Five multiple linear regressions (4 for different male age groups and 1 for female group ) for body length estimation were obtained. The multiple- relationship coefficient(R) was between 0.6237 and 0.7350, and the standard deviation was between 4.5720 and 7.0348. Conclusion The body length could be estimated by the sternum measurement data.However, its accurate was not as well as estimation by the long bone measurement. The male sternum multiple measurement data was significantly different from female. The body length can not be estimated only by the length of the sternal manubrium .
