The estimation of stature is a very important step in developing a biological profile for forensic identification. However, little previous work has been done on stature estimation among modern Thai people, despite a growing number of forensic cases in Thailand in recent years. The current study was carried out on a sample of 200 skeletons from a northern Thai population (132 males and 68 females), ranging in age from 19 to 94 years. The maximum lengths of six long bones (humerus, radius, ulna, femur, tibia and fibula) were measured and stature reconstruction formulae generated using linear regression. These equations were then tested on a holdout sample of 15 females and 15 males. Results reveal that the three lower limb bones are the most accurate estimators of stature among the males, with the fibula equation producing the lowest standard error of the estimate (SE=4.89cm), followed by the femur (SE=5.06cm). Results for females were mixed. The femur produced the lowest standard error among the females (SE=5.21cm), followed by the radius (SE=5.63cm). However, when tested against the holdout sample (n=30), the femur equations were considerably more accurate, with a mean absolute error of 3.5cm and a median absolute error of 2.4cm. Females exhibited a higher standard error of the estimate than reported in many previous studies. This higher error may be the result of a recent secular trend in stature affecting the females of our sample somewhat more than the males.
身高估计是建立法医学鉴定生物特征的重要步骤。然而，尽管近年来泰国的法医学案件数量不断增加，但针对现代泰国人的身高估计研究却很少。本研究对来自泰国北部人群的 200 具骨骼样本（132 名男性和 68 名女性）进行了研究，年龄范围为 19 至 94 岁。测量了六长骨（肱骨、桡骨、尺骨、股骨、胫骨和腓骨）的最大长度，并使用线性回归生成了身高重建公式。然后，将这些方程应用于 15 名女性和 15 名男性的验证样本中。结果表明，在男性中，三条下肢骨是最准确的身高估计器，其中腓骨方程的估计标准误差（SE=4.89cm）最低，其次是股骨（SE=5.06cm）。女性的结果则参差不齐。在女性中，股骨的估计标准误差最低（SE=5.21cm），其次是桡骨（SE=5.63cm）。然而，当应用于验证样本（n=30）时，股骨方程则更为准确，平均绝对误差为 3.5cm，中位数绝对误差为 2.4cm。女性的估计标准误差高于许多先前研究报告的结果。这种更高的误差可能是最近身高的世俗趋势影响了我们样本中的女性，而对男性的影响则相对较小。
