The estimation of stature using foot and hand dimensions is essential in the process of personal identification. The shapes of feet and hands vary depending on races and gender, and it is of great importance to design an adequate equation in consideration of variances to estimate stature. This study is based on a total of 5,195 South Korean males and females, aged from 20 to 59 years. Body dimensions of stature, hand length, hand breadth, foot length, and foot breadth were measured according to standard anthropometric procedures. The independent t-test was performed in order to verify significant gender-induced differences and the results showed that there was significant difference between males and females for all the foot-hand dimensions (p<0.01). All dimensions showed a positive and statistically significant relation with stature in both genders (p<0.01). For both genders, the foot length showed highest correlation, whereas the hand breadth showed least correlation. The stepwise regression analysis was conducted, and the results showed that males had the highest prediction accuracy in the regression equation consisting of foot length and hand length (R=0.532), whereas females had the highest accuracy in the regression model consisting of foot length and hand breadth (R=0.437) The findings of this study indicated that hand and foot dimensions can be used to predict the stature of South Korean in the forensic science field.
在个人识别过程中,利用手足尺寸估算身高至关重要。手足的形状因种族和性别而异,考虑到这些差异来设计合适的公式以估算身高非常重要。本研究基于5195名年龄在20至59岁之间的韩国男性和女性。按照标准人体测量程序测量了身高、手长、手宽、足长和足宽等身体尺寸。进行独立t检验以验证性别引起的显著差异,结果表明,在所有手足尺寸方面,男性和女性之间均存在显著差异(p<0.01)。所有尺寸在两性中均与身高呈正相关且具有统计学意义(p<0.01)。对于两性而言,足长的相关性最高,而手宽的相关性最低。进行了逐步回归分析,结果表明,在由足长和手长组成的回归方程中,男性的预测准确性最高(R=0.532),而在由足长和手宽组成的回归模型中,女性的准确性最高(R=0.437)。本研究结果表明,在法医学领域,手足尺寸可用于预测韩国人的身高。
