摘要：

目的 探讨猕猴胸骨柄性差特征、胸骨柄与锁骨、股骨长的相关性。 方法 太行山猕猴胸骨、锁骨和股骨标本45例（雄13例，雌32例）。选择6个线性测量变量，包括胸骨变量4个、锁骨长和股骨长。数据分析采用SPSS 22.0统计学软件，计算变量之间相关系数和偏相关系数。性别之间差异采用独立样本t检验。受试者工作特征曲线（ROC）分析得到每个变量识别性别的灵敏度和特异度。 结果 t检验显示胸骨变量性别差异显著（P<0.05）。胸骨柄前面宽正确判别率较高（84.4%），后面宽相对较低（66.7%）。胸骨变量与锁骨长相关性较强，与股骨长相关性较弱，通过胸骨柄去推测猕猴个体大小时误差较大。 结论 利用猕猴个体的胸骨柄标本可以识别个体的性别。运动方式和生活习性是造成胸骨形态特征差异的主要因素。

Abstract:

Objective To evaluate the sexual dimorphism in the sternum, and further to investigate whether a correlation exists between the sternal variables and the length of the clavicle and femur. Methods We examined intact sterna, clavicle and thighbone from 45 Macaca mulatta (13 males and 32 females). Six linear variables, including four sternal variables, length of clavicle and length of femur, were measured. Statistical analysis was done using SPSS 22.0 package, and t-test was used to determine the difference between sexes. A receiver-operator characteristic (ROC) curve analysis was conducted in order to identify the sensitivity and specificity of gender identification of each variable. The sex discrimination rate of each variable was derived using the discriminant analysis. Results The sexual differences of sternal variables were statistically significant (P<0.05). The correct discrimination rate was higher in anterior width of sternum (84.4%) and relatively lower in posterior width of sternum (66.7%). The correlation was higher between sternal variables and length of clavicle and weaker between sternal variables and length of femur. The error was larger when estimating stature using manubrium. Conclusion The manubrium of Macaca mulatta can be used for estimation of sex. The principal factors influencing sternum morphology may be locomotor and habit behavior.
