In order to correct height velocities for the confounders age and sex, SD scores can be calculated using the mean and the SD of the height velocity in the normal population. However, current methods are inappropriate for prepubertal children in the age range in which puberty occurs, because reference groups then consist of a mixed prepubertal/pubertal population. The mathematical infancy-childhood-puberty (ICP) model opens up the possibility of dissecting the puberty component from the total growth curve. New references for height velocity for prepubertal children calculated over a 12 month interval up to the ages of 15.5 years (boys) and 13.5 years (girls) have been constructed on the basis of adaptations of the ICP model and the Swedish longitudinal growth study.
为了校正年龄和性别等混杂因素对身高增长速度的影响,可以使用正常人群身高增长速度的均值和标准差来计算标准差分数。然而,目前的方法不适用于青春期开始年龄段的青春期前儿童,因为此时的参考群体是青春期前/青春期混合人群。数学上的婴儿期-儿童期-青春期(ICP)模型为从总生长曲线中剖析青春期部分提供了可能。基于ICP模型的调整以及瑞典纵向生长研究,构建了15.5岁(男孩)和13.5岁(女孩)以下12个月间隔的青春期前儿童身高增长速度的新参考标准。
