中国人胫骨的性别判定

【摘要】： 目的:建立中国人胫骨性别判定的方程。骨骼性别判定是法医人类学的重要研究内容。 方法:测量来自全国14省区的已知生前确切性别的180具(男150具,女30具)个体的双侧胫骨的13项指标,使用统计软件SPSS13.0,对所获得的测量数据,进行同一性别双侧间以及不同性别同侧间胫骨测量项目的t检验,最后用Fisher判别分析法,建立国人胫骨性别判定的方程式。 结果:建立单一测量指标的性别判别方程13组,其性别判别准确率为66.7%～96.7%;建立总判别方程,判别准确率为男性97.3%,女性93.3%;综合判别准确率为96.7。 结论:本研究提供的判别方程式判别准确率较高,适用于中国人胫骨的性别判定。多个测量指标的性别判别价值明显高于单一指标,且判别率随指标项目数的增多而增高。胫骨的单指标和多指标函数判别式可用于国人的性别判定,多指标函数判别式更具应用价值。尽管单一测量指标难以得到较高的判别准确率,但是可以用于胫骨破损情况下的性别判定。
[Abstract]:Objective: to establish the equation of tibia sex determination in Chinese. Skeletal sex determination is an important research content in forensic anthropology. Methods: thirteen indexes of bilateral tibia were measured in 180 individuals (150 males and 30 females) with known antemormal sex from 14 provinces and regions of China. The measured data were analyzed by SPSS13.0, software. T test of tibia measurement items between two sides of the same sex and the same side of the same sex was carried out. Finally, the equation of determining the tibia sex of Chinese was established by using Fisher discriminant analysis. Results: 13 groups of sex discriminant equation with single measurement index were established, the accuracy of sex discrimination was 66.7and 96.7.The total discriminant equation was established, the accuracy rate of discrimination was 97.3 for males and 93.3for females, and 96.7for comprehensive discrimination. Conclusion: the discriminant equation provided in this study has high accuracy and is suitable for sex determination of tibia in Chinese. The sex discriminant value of multiple measurement indexes was obviously higher than that of a single index, and the discriminant rate increased with the increase of the number of items. The single index and multi-index function discriminant of tibia can be used to judge the sex of Chinese people, and the multi-index function discriminant is more valuable. Although it is difficult to obtain high accuracy of single measurement, it can be used to judge the sex of tibia.
