Abstract
Short sleep duration in childhood has often been linked with obesity in later childhood or adolescence. However, whether infant sleep duration affects body composition trajectories and cardiovascular health through to mid-adolescence remains unknown. Methods: Participants were 336 adolescents from a community-based prospective birth cohort in Melbourne, Australia.
