哈萨克族成人掌骨的X线测量及其与身高的性别判别分析

目的 对新疆哈萨克族成人掌骨长度进行X线测量,探讨其性别差异及其有性别判别方法的相关性,为法医学及人类学提供判别率较高的性别判别式。方法 随机选择健康新疆哈萨克族成人200人（男100人,女100人）,进行双手后前位X线拍片,分别测量各掌骨长度,同时测量身高,将所得数据用SPSS15.0软件进行统计学分析处理。结果 男性第4掌骨长度以及女性第5掌骨长度左右手差别有显著性,男、女性第4、5掌骨长度左右手差别有显著性;同时应用Fisher法分析得出4个判别式,判别式分别为Y＝2.824r1＋2.563r4-0.654r5＋0.614l7-0.039l9＋2.452 l10-212.186,Y＝2.350r1＋2.377r4-0.995r5＋0.445l7＋0.046l9＋2.966 l10-191.622,Y＝0.393h1＋3.152r1＋0.435r5＋1.250 r10-463.734,Y＝0.362h1＋2.785r1＋0.028r5＋1.834 r10-404.748,判别率分别为89.67%、86.55%、90.00%和87.50%。结论 新疆哈萨克族男、女身高增长与掌骨增长密切相关。

Radiologic measurement and sexual diagnosis of metacarpal in Kazakh nationality by discriminant analysis

Objective To study the sex difference and discriminating formulas by measuring both metacarpal bones on X-ray and body height of Kazakh nationality adults,providing anatomical data for physical anthropology and forensic medicine. Methods The metacarpal bones length on X-ray films and body height from 200 adults of Kazakh nationality,including 100 male and 100 females were measured. The obtained date were statistically dealt by SPSS15.0 software. Results The length of the 4th metacarpal bone in male and the 5th in female were statistical significance beside, 4 discriminating formulas were obtained as follows: Y＝2.824r_1+2.563r_4-0.654r_5+0.614l7-0.039l_9+2.452l_(10)-212.186,Y＝2.350r_1+2.377r_4-0.995r_5+0.445l_7+0.046l_9+2.966l_(10)-191.622,Y＝0.393h_1+3.152r_1+0.435r_5+1.250r_(10)-463.734,Y＝0.362h_1+2.785r_1+0.028r_5+1.834 r_(10)-404.748, the accuracy being 89.67%、86.55%、90.00% and 87.50%. Conclusion The data presented in this paper indicates that the body height of male and female kazakh minority is closely related with the enlargement of their metacarpal bones.
