Abstract

To develop population - specific stature prediction equations from measurements of the lower limb bone in a contemporary Chinese. 303 individuals of Han group in Western China, including 201 females and 102 males were collected. The study sample was randomly divided into two subgroups. A calibration sample, which consisted of 171 females and 87 males, was used to develop the regression formula. A validation sample comprising the remaining 30 female and 15 male individuals was then used to test the predictive accuracy of the established formula. The regression equations were developed from intact bones and fragments of the femur, tibia and fibula, the maximum lengths of femur, tibia, and fibula were highly correlated with the stature. The maximum length of femur provide the most accurate result with the prediction accuracy of 3.84 cm for unknown sex, 4.00 cm in the male group, 3.45 cm in the female group, 3.61 cm in the group with age no more than 45, 3.45 cm in the group with age above 45. Moreover, the multiple regression equations were developed, and they portray a more accurate stature in instances in which the femur, tibia and fibula are available. This paper provides indications that the femur, tibia and fibula are important bones for stature estimation and they could be effectively used in forensic cases.

摘要

从中国西部汉族人群的下肢骨骼测量中建立特定人群的身高预测方程。共收集了 303 名个体,包括 201 名女性和 102 名男性。研究样本随机分为两组。校准样本由 171 名女性和 87 名男性组成,用于开发回归公式。然后,使用剩余的 30 名女性和 15 名男性个体组成验证样本,以测试建立公式的预测准确性。回归方程是从股骨、胫骨和腓骨的完整骨骼和碎片中得出的,股骨、胫骨和腓骨的最大长度与身高高度相关。股骨的最大长度提供了最准确的结果,对未知性别的预测准确率为 3.84 厘米,男性组为 4.00 厘米,女性组为 3.45 厘米,年龄不超过 45 岁的组为 3.61 厘米,年龄超过 45 岁的组为 3.45 厘米。此外,还开发了多元回归方程,它们在股骨、胫骨和腓骨都可用的情况下描绘了更准确的身高。本文表明,股骨、胫骨和腓骨是身高估计的重要骨骼,可有效用于法医案例。
