Premature Infant Growth Charts

Measurements for most preterm infants weighing 1500 grams or more at birth may be charted by chronologic age, with the adjusted age measurement alongside until age 2, in the 2000 WHO and CDC Growth Charts (CDC):

Although the World Health Organization (WHO) growth charts are recommended for use in term infants ages 0-24 months, the CDC has not evaluated their use for premature or very low-birth weight infants.
Based on data from two major studies, other growth charts are helpful for very low birth weight infants (<1500 grams at birth) [CDC: 2015]:

  • National Institute of Child Health and Human Development Neonatal Research Network Centers [Ehrenkranz: 1999] extend to 3 or 4 months of age
  • Infant Health and Development Program (IHDP) [Guo: 1997] [Roche: 1997] extend to age 36 months
  • Fetal-Infant Growth Charts from 22 Weeks GA to 66 or 92 Weeks Postconception Age [Lapillonne: 2013] - evaluates the growth adequacy during the first year of life in preterm infants according to sex (based on intrauterine growth measurements).
