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.
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.
