Abstract: Objective To establish functions for discriminating Chinese genders by tibia parameters.Methods 360 tibiae were collected from 180 known Chinese skeletons in 14 provinces(150 male and 30 female,aged 18 to 76).13 parameters were measured and analyzed by statistical software SPSS13.0.Independentsamples t test was made between left and right of tibiae of the same gender first,and then between male and female of the right tibiae.Data of right tibiae of male and female was sub-jected to Fisher discriminant analysis for constructing the gender discriminant function.Results There are 13 discriminating functions for the single measurement of tibiae.The correct rate is 66.7%~96.7%.The correct rate by discriminant functions in-cluding 13 measurements is 97.3% for the male and 93.3% for the female,respectively.Conclusions The gender discriminant functions are effective for Chinese gender discrimination by tibiae.

摘要： 目的建立中国人胫骨性别判定的方程。方法测量来自全国14省区已知生前确切性别的180例(男150例,女30例)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%,总判别方程的判别准确率为男性97.3%,女性93.3%。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。
