“…From birth, BMI increases and reaches a peak around 9 months of age (“infancy peak BMI” or “adiposity peak”), then gradually drops to a low point in the range of 4–6 years old (“adiposity rebound”) [9, 10], and after that continues to rise up through adolescence until adulthood. An alternative promising approach is the use of infancy BMI trajectories (and associated characteristics such as the magnitude and timing of infancy BMI peak), which have been shown by several studies to be predictive of adiposity in children and in adulthood [9, 10, 11, 12, 13].…”
