Postnatal growth of etiologically characterized preterm newborns according to gestational age at birth.

ABSTRACT:

Objective

To examine the relationship between etiologically-based preterm birth sub-groups and early postnatal growth according to gestational age at birth.

Methods

Prospective, multinational, cohort study involving 15 hospitals that monitored preterm newborns to hospital discharge. Measures/exposures: maternal demographics; etiologically-based preterm birth sub-groups; very, moderate and late preterm categories, and feeding.

Primary outcomes

serial anthropometric measures expressed as z-scores of the INTERGROWTH-21^st preterm postnatal growth standards.

Results

We included 2320 singletons and 1180 twins: very=24.4% (n = 856, including 178 < 28 weeks' gestation); moderate=16.9% (n = 592) and late preterm=58.6% (n = 2052). The median (interquartile ran
