The aim of the study is to develop accurate stature estimation models for a contemporary Western Australian population from measurements of the feet and footprints. The sample comprises 200 adults (90 males, 110 females). A stature measurement, three linear measurements from each foot and bilateral footprints were collected from each subject. Seven linear measurements were then extracted from each print. Prior to data collection, a precision test was conducted to determine the repeatability of measurement acquisition. The primary data were then analysed using a range of parametric statistical tests. Results show that all foot and footprint measurements were significantly (P < 0.01-0.001) correlated with stature and estimation models were formulated with a prediction accuracy of ± 4.673 cm to ± 6.926 cm. Left foot length was the most accurate single variable in the simple linear regressions (males: ± 5.065 cm; females: ± 4.777 cm). This study provides viable alternatives for estimating stature in a Western Australian population that are equivalent to established standards developed from foot bones.
本研究的目的是通过对足部和脚印的测量，为当代西澳大利亚人群开发准确的身高估计模型。样本包括200名成年人（90名男性，110名女性）。收集了每个受试者的身高测量值、每只脚的三个线性测量值和双侧脚印。然后从每个脚印中提取七个线性测量值。在数据收集之前，进行了精度测试以确定测量采集的可重复性。然后使用一系列参数统计测试对主要数据进行分析。结果表明，所有足部和脚印测量值均与身高显著相关（P < 0.01 - 0.001），并制定了估计模型，预测精度为±4.673厘米至±6.926厘米。在简单线性回归中，左脚长度是最准确的单一变量（男性：±5.065厘米；女性：±4.777厘米）。本研究为西澳大利亚人群的身高估计提供了可行的替代方法，这些方法等同于根据足部骨骼制定的既定标准。
