预测儿童身高的生长模型对于总结个体和群体的生长模式和时间是有用的。Jolicoeur等人描述了JPPS模型，并将其与Preece和Baines（PB 1）以及Shohoji和Sasaki（SS）的模型进行了比较。最近Jolicoeur等人描述了JPA2模型，它是JPPS的扩展。与PB 1模型和SS模型（SSC）的修改相比，JPPS模型在这里进行了更深入的研究，并有更多的受试者。JPPS模型始终给出最佳拟合，尽管SSC模型也明显优于PB 1。结果表明，生物参数可以从模型参数。婴儿期和成人期的数据都需要JPPS模型拟合良好。在某些受试者中，JPPS速度曲线显示了中期增长的井喷式增长，但它通常并不表明基础数据中的井喷式增长。SSC模型被证明是类似于Karlberg的ICP模型。总的来说，JPPS模型提供了一个很好的拟合儿童身高曲线。
Growth models for predicting child stature are useful to summarize both the pattern and timing of growth in individuals and populations. Jolicoeur et al. described the JPPS model and compared it with the models of Preece and Baines (PB 1) and Shohoji and Sasaki (SS). More recently Jolicoeur ct al. described the JPA2 model, an extension of the JPPS. Here the JPPS model is studied in greater depth, and with more subjects, compared to the PB 1 model and a modification of the SS model (SSC). The JPPS model gives consistently the best fit, although the SSC model is also better appreciably than the PB 1. It is shown that biological parameters can be derived from the model parameters. Both infancy and adult data are required for the JPPS model to fit well. In some subjects the JPPS velocity curve suggests a mid-growth spurt, but it does not usually indicate a spurt in the underlying data. The SSC model is shown to be similar to Karlberg's ICP model. Overall the JPPS model provides a good fit to the child stature curve.
