Insights

New INTERGROWTH-21st growth standards are recommended for newborn care, replacing older Fenton and Kim curves. These updated references provide better evaluation of infant size at birth and postnatal development.

Area of Science:

  • Neonatalogy
  • Pediatrics
  • Public Health

Background:

  • Accurate newborn size and growth standards are crucial for guiding infant care practices.
  • Previous references, such as Fenton and Kim, have been widely used but are now being superseded.
  • The INTERGROWTH-21st project offers updated, prescriptive growth standards.

Purpose of the Study:

  • To recommend the adoption of the INTERGROWTH-21st growth standards for neonatal assessment in Argentina.
  • To replace the previously utilized Fenton and Kim growth curves with newer, more comprehensive standards.

Main Methods:

  • The INTERGROWTH-21st project developed prescriptive standards for size at birth (from 33 weeks gestation) and postnatal growth (from 27 weeks gestation).
  • References for early gestational ages (24 to 32.6 weeks) were also established.
  • The Argentine Society of Pediatrics' committees and the National Government of Health endorsed these new standards.

Main Results:

  • The INTERGROWTH-21st standards provide comprehensive growth evaluation from early gestation through postnatal development.
  • These new standards are recommended to replace the Fenton and Kim curves in clinical practice.
  • The adoption of INTERGROWTH-21st standards aims to improve the evaluation and care of newborns.

Conclusions:

  • The INTERGROWTH-21st standards represent a significant advancement in neonatal growth assessment.
  • Official recommendation in Argentina supports the transition from Fenton and Kim to INTERGROWTH-21st curves.
  • This shift is expected to enhance the quality of care for newborns through improved growth monitoring.
