摘要

当身高难以测量时，膝关节高度常被用于身高预测。本研究的目的是使用泰国 妇女膝盖高度估计身高并验证预测方程。选择年龄在18-59岁之间，居住在曼谷 或周边三省的成年妇女作为研究对象。将研究对象分配到两组中的一组，方程 拟合组（488例）和方程验证组（188例）。使用测距仪和膝盖高度卡尺测量站 高和膝盖高度。拟合组和验证组的年龄和身体特征具有可比性。测得的身高与 平均膝盖高度呈显著正相关（r=0.84，0.001）。在回归模型中膝盖高度对身高 具有最准确的预测价值（调整R2=0.718，标准误差=2.80），根据公式“高度 =38.1+2.45（平均膝盖高度）-0.051（年龄）”。这项研究提出了利用泰国成年妇 女膝盖高度估计身高的新的估计方程。该方程比以前在泰国进行的研究具有更 高的估计能力。

Knee height has been the most frequently used measure for height prediction where full height is difficult to measure. The aim of this study was to develop and validate predictive equations using knee height to estimate the height of Thai women. The female participants were 18-59 years of age and lived in Bangkok or three surrounding provinces. They were assigned to one of two groups; the equation development group (n=488) and the equation validation group (n=188). Standing height and knee height were measured in duplicate using a stadiometer and a knee height calliper. Age and physical characteristics of the equation development group and the validate group were comparable. The measured heights showed a significant strongly positive correlation with the mean knee height (r=0.84, p＜0.001). Mean knee height in a regression model exhibited the most accurate height prediction (adjusted R^2=0.718, standard error of estimate=2.80), according to the equation ＂Height=38.1+2.45 (average knee height) - 0.051(age)＂. This study proposes a new height estimation equation for Thai adult women using knee height. The equation shows more estimation power than the previous studies conducted in Thailand.
