中国汉族男女股骨性别差异

经测量235副（男158副，女77副）已知生前确切性别的成年股骨的21项指标，对单一测量项目判定股骨性别的效果进行了检验。结果表明，21项测量指标中有11项单一指标的判别效果达80％以上。采用Fisher两类判别分析法对测量数据进行统计处理，得到根据单侧股骨测量值判别性别的函数方程14个；对南方和北方人群组的测量数据，分别用Fisher两类判别法进行统计，建立了根据单侧股骨测量值判断性别的函数34个，判别率最高达98．23％。与盲测判别准确率相近。该法可用于法医人类学的个体识别。

STUDY OF THE SEX DIFFERENCES OF FEMORA OF CHINESE HAN POPULATION

The sample of this study consists of 235 femora of known sex and race. 21 items of femoral measurements were carried out. The population was divided into two groups: the northern group and the southern group. The statistic analysis showed that except condylo-diaphyseal angle of the femur allmeasurements had significant sex differences. Good result can be obtained by using single measurernentfor sexing. Some rneasurements at both ends of femur was more efficient for sexing than measurements of length. The length between trochanter major and trochanter minor and femur weight werealso good criteria for sex deterrnination. 48 sex discriminating functions of femur left and right]wereestablished by means of Fisher's method and stepwise discriminating analysis with discriminating rateof 98. 23 %. It is useful for personal identification in the field of forensic anthropology.
