About

The purpose of this study is to improve health professionals understanding of preterm infant growth patterns, and to determine if early growth patterns predict risks of adverse metabolic and cognitive outcomes.

Full description

The purpose of this study is:

To improve health professionals understanding of preterm infant growth patterns, and to determine if growth patterns (rapid early growth in the first 2 weeks of life, weight less than the 10th percentile at the time of discharge) predict risks of adverse metabolic outcomes (measured as overweight at age 3) once the following variables are controlled for: size at birth (z-score), neonatal morbidities, social determinants of health, and nutritional adequacy in the neonatal intensive care unit (NICU).

To assess diagnostic accuracy of 36-week anthropometric weight, length and head circumference <10th and <3rd percentiles to predict preterm infant cognitive impairment.

Enrollment: 1,275 patients

Sex: All

Ages: Under 3 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• < 32 weeks gestational age at birth

Exclusion criteria

• infants who had congenital anomalies or those who died prior to discharge

Trial design

1,275 participants in 4 patient groups

Size < the 3rd or 10th percentiles

Description:

Infant size smaller than the 3rd or 10th percentiles relative to the Fenton growth chart for weight or head circumference at discharge from neonatal intensive care

Treatment:

Other: Growth

Rapid early growth

Description:

Rapid early growth will be defined as exceeding birthweight in the first week of life

Growth velocity calculation methods

Description:

We will compare a variety of growth velocity calculation methods used in clinical care and research to compare and assess growth velocity calculation methods

Size for gestational age

Description:

Small size for gestational age
