The Illusion of Catch-up Growth in Premature Infants: Use of the Growth Index and Age Correction

The corrected growth data of appropriate-for-gestational-age children approximated normal expected growth, whereas small-for-gestational-age children still demonstrated subnormal growth at 29 months of age, despite correction. In both appropriate-for-gestational-age and small-for-gestational-age children, catch-up growth appears to be a statistical illusion created by charting growth of premature infants using chronological age rather than the more appropriate corrected age.
