This study assesses the use of postcranial elements for sex estimation taking population variability into account. European American and Latin American populations are independently analyzed. Nine measurements from postcranial elements were collected from 72 European American individuals, and 59 Latin American individuals. Statistical analyses were performed using the Statistical Package for Social Science (SPSS) version 15. Statistical analyses were conducted to corroborate that there were no intra- or interobserver errors. In both populations, significant differences were found on all measured traits between males and females, except Scapular Breadth in Latin Americans. According to Discriminant Function Analysis (DFA) in the European American population the Ulna Minimum Breadth of the Olecranon (UMBO) correctly classified 91.3% of individuals. When this parameter was combined with the Diameter of Humeral Head (HHD), the two correctly classified 98% of individuals. In Latin Americans, the UMBO correctly classified 82.4% of the individuals. When combined with HHD, the measurements correctly classified 79.4% individuals. UMBO is the most useful trait to correctly assign the sex of the remains in both populations. Including the HHD improved accuracy rates in the European American sample. These results are in agreement with previous studies, which named the humerus as one of the potentially useful bones to consider for sex estimation based on its accuracy. Thus, these two anatomical regions could be used alone or in combination with other methodologies for sex estimation, which is particularly important in situations of fragmentary remains and incomplete skeletons.
本研究评估了考虑到人群变异性后使用后体节元素进行性别估计的情况。对欧洲裔美国人和拉丁裔美国人进行了独立分析。从 72 名欧洲裔美国人和 59 名拉丁裔美国人中收集了 9 个后体节元素的测量值。使用社会科学统计软件包（SPSS）版本 15 进行了统计分析。进行了统计分析以证实没有观察者内或观察者间的误差。在两个群体中，除了拉丁美洲人的肩胛骨宽度外，所有测量的特征在男性和女性之间均存在显著差异。根据欧洲裔美国人中的判别函数分析（DFA），尺骨的鹰嘴最小宽度（UMBO）正确分类了 91.3%的个体。当将此参数与肱骨头直径（HHD）结合使用时，两个参数正确分类了 98%的个体。在拉丁裔美国人中，UMBO 正确分类了 82.4%的个体。当与 HHD 结合使用时，测量结果正确分类了 79.4%的个体。UMBO 是两种人群中正确分配遗骸性别的最有用特征。在欧洲裔美国人样本中，包含 HHD 可提高准确性。这些结果与先前的研究一致，先前的研究将肱骨命名为基于其准确性可用于性别估计的潜在有用骨骼之一。因此，这两个解剖区域可以单独使用或与其他性别估计方法结合使用，这在遗骸碎片和不完整骨骼的情况下尤为重要。
