About this study
This study was a multicenter, prospective cohort study to define postnatal longitudinal growth for very low birth weight (VLBW) infants. The objectives were: 1) to develop postnatal growth curves for VLBW preterm infants that would permit an assessment of growth velocity; 2) to relate growth velocity and nutritional practices (duration of parenteral nutrition, age at first enteral feeding, and age at full enteral feeding); 3) to compare growth velocity in infants who are small-for-gestational age (SGA) with infants who are appropriate-for-gestational age (AGA); and 4) to relate growth velocity to several common, major morbidities, including chronic lung disease (CLD), nosocomial infection (or late-onset infection) and necrotizing enterocolitis (NEC). These growth data may be useful in identifying preterm infants who are growing slowly despite current nutritional support and in designing and performing clinical trials of nutritional interventions.
Read the detailed description
Previous growth curves for premature infants were based on a 1948 study of 100 infants. More recent reports described growth rates for VLBW infants exceeded those predicted by the previous study. The authors suggested that the differences may reflect changes in nutritional management and cautioned that the observed growth rates may not be optimal. Although a greater number of extremely low birth weight infants were included in these studies, data for infants with birth weights <750 g was still limited.

Data were collected on 1660 infants with birth weights between 501 to 1500 g who were inborn or admitted at 24 hours of age or less to 1 of the 12 National Institute of Child Health and Human Development (NICHD) Neonatal Research Network centers between August 31, 1994 and August 9, 1995, survived >7 days (168 hours) and were free of major congenital anomalies. Infants were weighed daily for a minimum of 14 days or until birth weight was regained, whichever occurred later, and then weekly. Recumbent length was measured weekly with a Premie Length Board. Head circumference (HC) was measured weekly. Midarm circumference (MAC) was measured weekly. Length, HC, and MAC measurements were each performed twice.

Where is the study taking place?
The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01203475, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2015; AzTrials last refreshed its copy on 27 Oct 2026.
