Aim: To provide growth charts for clinical monitoring of extra‐uterine growth from birth to full‐term age, in infants born before 26 weeks of gestation, hospitalized at neonatal intensive care unit (NICU), and compare it to the commonly used Swedish preterm birth‐size reference. Methods: This retrospective longitudinal cohort comprised all infants born before 26 + 0 weeks of gestation and surviving to full‐term age (n = 162), admitted to the NICU, Karolinska Hospital during the period January 1990 to December 2002. Body weight was recorded daily, head circumference (HC) weekly and length twice a month. Results: Birth weight (BW), length and HC showed a normal distribution without significant gender difference. The majority of the infants showed a pronounced postnatal growth restriction for all growth variables with increasing deviation from the reference with age. The mean initial weight loss was 16% with nadir at 6 days of age and a mean time to regain BW of 18 days. At discharge from NICU, 75% of those initially appropriate for gestational age infants were below –2 standard deviation scores for at least one of the body size variables. Conclusion: The poor extra‐uterine growth pattern points to the need of growth curves for extra‐uterine growth of extremely premature infants.
