【摘要】： 目的:探讨应用股骨进行性别判别的方法,建立股骨性别判别的函数判别式。方法:测量来自全国14省区的已知生前确切性别180例(男150例,女30例)个体的双侧股骨21项指标。使用统计软件SPSS13.0对获得的股骨测量项目数据,进行同一性别双侧间及不同性别同侧间的t检验,然后采用Fisher判别分析法和Bayes逐步判别分析法,建立股骨性别判定的系列判别函数。结果:(1)男性或女性股骨的左、右侧指标测量值的侧别差异均无统计学意义(P0.05),可以选择单侧进行研究。 (2)股骨21项指标测量值的性别差异均具有极显著意义(P0.01),可以利用其进行性别判别。 (3)获得股骨21个单指标函数判别式及1个多指标函数判别式,其中单一测量指标中男性判别率最高指标为股骨上髁宽,为94.0%,女性判别率最高指标为股骨头周与股骨颈垂直径,为93.3%,总判别方程的判别率为男性98.0%,女性93.3%。结论:股骨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。
[Abstract]:Objective: to establish the functional discriminant of femur sex discrimination by using femur sex discrimination method. Methods: 21 indexes of bilateral femur were measured in 180 individuals (150 males and 30 females) from 14 provinces of China. The data of femur measurement items obtained by statistical software SPSS13.0 were used for t test between two sides of the same sex and the same sex, then Fisher discriminant analysis and Bayes stepwise discriminant analysis were used. To establish a series of discriminant functions for femur sex determination. Results: (1) left femur of male or female, (2) the gender differences of the measured values of 21 indexes of femur are significant (P0.01), and can be used to carry out sex research. (2) the gender difference of the measured values of 21 indexes of femur is significant (P0.01). (3) 21 single index function discriminations and 1 multiple index function discriminant were obtained. In the single measure, the highest discriminant rate of male was the width of femoral epicondyle (94.0), the highest of female was circumference of femoral head and the vertical diameter of femoral neck (93.3cm). The discriminant rate of total discriminant equation was 98.0 for male and 93.3for female. Conclusion: single index and multi-index function discriminant can be used to judge the sex of Chinese people, and multi-index function discriminant is more valuable.
