中国汉族人腰椎的性别差异

目的提供体质人类学的数据资料 ,建立中国汉族腰椎性别判别的方法。方法根据人体骨骼测量方法 ,测量 117付 (男 80 ,女 3 7付 ,年龄 17～ 90岁 )中国汉族人腰椎的 10项指标 ;选择性别差异显著的椎测量项目 ,建立腰椎及各腰椎的性别判别方程。结果第一至第五腰椎均有 5个以上的测量项目的数据存在显著意义的性别差异 (P<0 0 5 ) ;建立的 5个腰椎及各腰椎的性别判别方程 ,判别率在 69 4%～ 91 8% ,以 5个腰椎的多项指标的性别判别方程的准确率最高 (91 8% ) ,其次为第一腰椎 (84 5 % )和第二腰椎 (82 1% )。结论中国汉族人腰椎的性别差异以第一和第二腰椎明显 ,腰椎性别判定以多项指标的准确率高

A study on the gender discrepancy of lumbar vertebra from Chinese Han population

Objective In oder to enrich data of physique anthropology and method of individual identification,a lumbar vertebra sexing method was constructed with the discriminant analysis.Method The multiple indexes of human lumbar vertebra of Chinese Han population were measured according to the measurement methods of human bone.117 samples were used(male 80,female 37;age 17～90,mean age 40).10 items of lumbar vertebra measurements were carried out.The items with marked sex difference were then chosen.Results A serial formulas were obtained from each lumbar vertebra and five lumbar vertebra indexes,the discriminant rates were between 69 4% to 91 8% respectively.The discriminant rates of the 1th and 2 nd lumbar vertebra were the highest which were 84 5% and 82 1% respectively.Conclusion The research demonstrated that the discriminant rates obtained from multiple lumbar vertebra indexes were higher than those from the single lumbar vertebra.The discriminant rates obtained from the 1th and 2 nd lumbar vertebra were higher than those obtained from other lumbar vertebra.
