The JPPS model offers superior accuracy for tracking human stature growth from birth to adulthood compared to older Preece and Baines models. This advanced model provides better fits and smaller errors for comprehensive growth analysis.

Area of Science:

  • Human growth and development
  • Biomathematics
  • Auxology

Background:

  • Accurate modeling of human stature growth is crucial for understanding developmental trajectories.
  • Previous models, such as those by Preece and Baines, have limitations in fitting growth data across all age ranges.
  • The development of robust and accurate growth models is an ongoing area of research.

Purpose of the Study:

  • To compare the performance of established (Preece and Baines) and recent (JPPS) mathematical models for human stature growth.
  • To evaluate model fit, robustness, and applicability across the entire growth spectrum from infancy to adulthood.
  • To identify the most suitable asymptotic model for human stature growth analysis.

Main Methods:

  • Comparative analysis of three growth models: Preece and Baines (5- and 6-parameter) and the JPPS (7-parameter) model.

  • Application of models to longitudinal auxological data from 27 healthy French children (birth to adulthood).
  • Evaluation metrics included residual mean squares and model robustness.

    • Main Results:

    • The JPPS model demonstrated significantly smaller residual mean squares compared to Preece and Baines models.
    • JPPS model accurately fits data from infancy through adulthood and passes through the origin.
    • Preece and Baines Model No. 3 showed larger residual mean squares and less robustness than Model No. 1.

    Conclusions:

    • The JPPS model is currently the most satisfactory asymptotic model for human stature growth.
    • The JPPS model offers superior performance over existing Preece and Baines models for comprehensive growth assessment.
    • Model invariance and fit across developmental stages are key factors in selecting growth models.
