Data on the growth of 1063 children and their parents were analysed. Of the variation in height at prepuberty about 20%, and of the final height 30-46%, were explained by the variation in parental heights; the children's own height at the age of 1.0 year increased the proportion explained to half. Two equations were developed for increasing the accuracy of the evaluation of growth. One defines parent specific mean height standard deviation score, and the other includes the parents' heights and the child's height at the age of 1.0 year and defines expected standard deviation score for height. These equations are easy to use if they are converted to nomograms.
对1063名儿童及其父母的生长数据进行了分析。青春期前身高变异的约20%以及最终身高变异的30 - 46%可由父母身高的变异来解释;孩子1.0岁时自身的身高使可解释比例增加到一半。为提高生长评估的准确性制定了两个方程。一个定义了父母特定的平均身高标准差分数,另一个纳入了父母的身高以及孩子1.0岁时的身高,并定义了身高的预期标准差分数。如果将这些方程转换为列线图,就很容易使用。
