Insights

The INTERGROWTH-21st Project established new fetal and preterm infant growth standards. Standardized anthropometric protocols ensured high-quality data for optimal international growth indicators.

Area of Science:

  • Pediatrics
  • Human Growth and Development
  • Anthropometry

Background:

  • Optimal fetal and preterm infant growth requires accurate, standardized measurement tools.
  • Existing growth charts may not reflect diverse international populations.
  • The INTERGROWTH-21st Project addresses the need for updated, prescriptive growth standards.

Purpose of the Study:

  • To detail the rigorous methodology for constructing new fetal and preterm infant growth standards.
  • To ensure the validity and reliability of anthropometric data collected across multiple international sites.
  • To establish a foundation for optimal fetal and postnatal growth assessment.

Main Methods:

  • Selection and training of anthropometric personnel across international study sites.
  • Standardization of anthropometric equipment and measurement techniques.
  • Detailed description of calibration protocols for all measurements.

Main Results:

  • Implementation of standardized protocols ensured high-quality anthropometric data.
  • Consistent measurement techniques were applied across all participating centers.
  • The methodology provides a robust framework for international growth standard development.

Conclusions:

  • Standardized anthropometric protocols are critical for valid international growth standards.
  • The INTERGROWTH-21st Project's methodology ensures data quality for optimal growth assessment.
  • These standards will improve the evaluation of fetal and preterm infant growth globally.
