Summary

New references for height velocity in prepubertal children were created using the infancy-childhood-puberty (ICP) model. These improve accuracy for children nearing puberty, addressing limitations of current growth assessment methods.

Area of Science:

  • Pediatric endocrinology
  • Human growth and development

Background:

  • Accurate height velocity assessment is crucial for monitoring child growth.
  • Current methods for calculating SD scores for height velocity are inaccurate for prepubertal children approaching puberty.
  • Reference groups often mix prepubertal and pubertal children, confounding results.

Purpose of the Study:

  • To develop new, accurate reference standards for height velocity in prepubertal children.
  • To address the limitations of existing methods in the pre-pubertal age range.
  • To utilize the infancy-childhood-puberty (ICP) model for improved growth curve analysis.

Main Methods:

  • Adaptation of the mathematical infancy-childhood-puberty (ICP) model.
  • Construction of new height velocity references using a 12-month interval.

  • Utilizing data from the Swedish longitudinal growth study.

    • Main Results:

    • New height velocity references were calculated for prepubertal children up to 15.5 years (boys) and 13.5 years (girls).
    • The adapted ICP model allowed for the separation of pubertal growth components.
    • These references provide a more accurate assessment for the target age group.

    Conclusions:

    • The developed references provide a more precise tool for assessing height velocity in prepubertal children.
    • The ICP model offers a valuable approach to dissecting growth phases.
    • These findings enhance the accuracy of growth monitoring in pediatric populations.
