The Role of Linear Growth and Fat-Free Mass Gain in Determining Cognitive Outcomes in Extremely Preterm Infants

Study Purpose

The aim of this study is to learn more about the association between early growth and later development in infants born prematurely. We know from previous studies that preterm infants undergo periods of slower growth while in the hospital. The purpose of this study is to identify both nutritional and non-nutritional factors that lead to altered body composition and potentially affect later development.

Study Developments

We are busy working on analyzing the data we’ve collected so far. We’ve posted several journal articles and poster presentations from scientific conferences, and we will update this website with any future publications or presentations. Please feel free to direct any questions you may have regarding these to Neely Miller at

Moving Forward

With all this in mind, we are looking ahead and excited about things to come. We have truly enjoyed seeing the children grow up and are excited to follow them to 4 years old. A big thank you to the wonderful families who have been so dedicated to the research we have been doing. We couldn’t do this without you!
