Abstract

Analyzing skeletal remains is crucial for identifying individuals, and forensic anthropologists use this analysis to determine biological characteristics, particularly sex, aiding criminal investigations. Among thoracic vertebrae, the twelfth thoracic vertebra (T12) is highly sexually dimorphic in various populations. This study aims to establish a discriminant function equation (DFE) for sex determination based on T12 in the Central Thai population. A total of 15 parameters of T12 were examined in 69 bone samples (43 males and 26 females). Among the 15 parameters, 14 were significantly different between males and females. The discriminant function equation (DFE) was generated as DFE = −19.578 + 0.376(i) BDsm + 0.254(l) PW + 0.081TDm, with a cutoff value of −0.296 for males and females, showing 92.8 % accuracy. The evaluation of the DFE using 10 blind samples showed 90 % accuracy. These findings may offer an additional method for sex determination through T12, complementing the examination of other skeletal elements.

泰国中部人群第十二胸椎的性别二形性，用于性别鉴定

分析骨骼遗骸对识别个人身份至关重要，法医人类学家利用这种分析来确定生物特征，特别是性别，从而帮助刑事调查。在胸椎中，第十二胸椎（T12）在不同人群中具有高度的性别二态性。本研究旨在建立一个基于泰国中部人群 T12 的性别判定判别函数方程（DFE）。共对 69 个骨骼样本（43 个男性样本和 26 个女性样本）的 15 个 T12 参数进行了检测。在这 15 个参数中，有 14 个参数在男性和女性之间存在显著差异。生成的判别函数方程（DFE）为 DFE = -19.578 + 0.376(i) BDsm + 0.254(l) PW + 0.081TDm，男性和女性的临界值为-0.296，准确率为 92.8%。使用 10 个盲样对 DFE 进行的评估显示，准确率为 90%。这些发现为通过 T12 进行性别鉴定提供了一种新方法，是对其他骨骼元素检查的补充。
