Body composition is a sensitive marker of infants’ intra- and extrauterine growth quality that can influence short- and long-term outcomes; including retinopathy of prematurity, bronchopulmonary dysplasia (BPD), metabolic health, cardiovascular and neurodevelopmental outcomes.

The study wants to explore the longitudinal association of neonatal adiposity (fat mass percentage) with BMI trajectories and childhood overweight and obesity from ages 2 to 6 years.

Chronic kidney disease (CKD) is characterized by accelerated aging, but the age-related changes in body composition and its modification by sex and race are unclear.

In this study, only the change in FM% in the first 6 months of life was associated with more adiposity at age 2 years. Infants with a rapid increase in FM% had higher trajectories of FM% and FM index during the first 2 years of life. These findings appear to support a critical window for adiposity programming in early life.

The aim of this study is to characterize changes in body composition during pregnancy in women with obesity.
