What is the Fenton 2013 growth chart?

The Fenton 2013 chart provides sex-specific growth curves for preterm infants from 22-50 weeks postmenstrual age (PMA), derived from a meta-analysis of 6 large international datasets.

How is growth failure defined in preterm infants?

Growth failure is typically defined as weight, length, or head circumference below the 10th percentile (z-score < -1.28), or a drop of 2 or more z-score lines from birth.

When does a preterm infant transition from Fenton to WHO charts?

The Fenton chart transitions to WHO growth standards at 50 weeks PMA (approximately 10 weeks corrected age), when the preterm growth norms align with term infant growth patterns.
