除了少数使用纵向抽样的研究外，几乎所有可用的高度生长参考值集都是以横断面方式构建的。然而，这种参考值是有缺陷的，因为青春期的时间有很大的个体差异，特别是在青春期成熟早或晚的儿童中。一个额外的复杂因素是，与成熟较晚的个体相比，早熟个体的青春期生长突增幅度要大得多。本研究基于145名瑞典健康儿童的纵向跟踪生长记录，引入了一种青春期前身高评估标准，用于青春期晚发儿童的青春期前身高评估。通过在包含青春期前参考值的图表中绘制儿童的身高值，可以通过在1年内青春期前身高标准差得分值的0.3或以上的变化来识别青春期生长突升的开始。一旦确定了发育期，就可以对数据应用高度精确的最终身高预测方法，如本文所述，其中发育期的身高和年龄是唯一需要的两个度量。两性预测模型的r(2)值均大于0.80。最后，提出了一种评估青春期总身高增长的方法。该方法根据青春期的时间进行调整，并基于青春期开始时的身高和年龄，加上观察到的最终身高。版权所有(C) 2003 S.

Almost all available sets of height growth reference values are constructed in a cross-sectional manner, except for a few studies in which longitudinal sampling was used. Such reference values are, however, flawed because of considerable individual variation in the timing of puberty, especially among children with early or late pubertal maturation. An additional complicating factor is that the magnitude of the total pubertal growth spurt is significantly larger among those individuals with early pubertal maturation, compared with late maturation. Based on the growth records of 145 healthy Swedish children followed longitudinally, this study introduces a pre-pubertal standard for the assessment of pre-pubertal height for children with late onset of puberty. By plotting the height values of a child in a chart containing prepubertal reference values, the onset of the pubertal growth spurt can be identified by a change in the prepubertal height standard deviation score values of 0.3 standard deviations or more over a period of 1 year. Once the pubertal onset is established, a highly accurate final height prediction method can be applied to the data, as described in this article, in which height and age at pubertal onset are the only two measures required. The r(2) value of the prediction model was over 0.80 for both sexes. Finally, a method for assessing total pubertal height gain is presented. The method adjusts for the timing of puberty and is based on the height and age at pubertal onset, plus the observed final height. Copyright (C) 2003 S. Karger AG, Basel.
