Greater within‐person weight variability during infancy predicts future increases in z‐BMI

This study tested the hypothesis that greater weight variability (WV; measured as root mean square error [RMSE]) during the first year of life predicts weight gain at year two and greater WV during the second year of life predicts greater weight gain at year three.This was a prospective study using mother and offspring data from the Avon Longitudinal Study of Parents and Children. Infant z-BMI (BMI z score) and WV scores were calculated...
