Infant Weight Growth Trajectories Differ by Feeding Mode

Year: 2026

Type: article

Abstract: Objectives: Rapid weight gain during infancy is a well-established predictor of childhood obesity. Breastfeeding (BF) is associated with differences in infant growth trajectories; however, studies examining this relationship are often cross-sectional or treat feeding mode or rapid weight gain as fixed categorical variables rather than time-varying measures. This limitation may obscure time-dependent relationships between feeding mode and weight gain. In response, this analysis examined the longitudinal association between the time-varying feeding mode and changes in weight-for-age z scores (ΔWAZ), a continuous measure of rapid weight gain.
