Postnatal growth failure of very low-birth-weight infants in Southwest Iran: A descriptive analytical study.

Background And Aims: Preterm infants are more prone to poor growth and neurodevelopment. The first few weeks of life play an important role in the growth and neurodevelopment of very-low-birth-weight (VLBW) infants. The Vermont Oxford Network, evaluating the postnatal growth of preterm newborns, considers growth failure as body weight <10th percentile for postmenstrual age.
