Overview

Retrospective study evaluates neonatal malnutrition indicators' reliability in preterm infants, suggesting the need for new criteria.

Key Points

  • The study aims to evaluate the reliability of 2018 neonatal malnutrition criteria in diagnosing malnutrition in preterm infants.
  • Retrospective review of 2305 preterm infants admitted to a level III neonatal intensive care unit from 2013 to 2022
  • Malnutrition diagnoses were assigned using established weight and growth indicators based on Fenton growth chart
  • Kappa values assessed both inter-indicator and intra-indicator reliability of malnutrition criteria.
  • Poor inter-indicator reliability was found for diagnosis in the first 2 weeks of life (k = 0.054) and thereafter (k = 0.087)
  • Better reliability was noted among growth-based indicators compared to others
  • Intra-indicator reliability was strong for weight gain velocities (k = 0.86 to 0.94) but poor for linear growth definitions (k = 0.12).
