Impact of early rapid weight gain on odds for overweight at one year differs between breastfed and formula-fed infants.

ABSTRACT:

Background

Early rapid weight gain (RWG) increases, whereas longer durations of breastfeeding decreases, odds for later obesity.

Objectives

To determine the independent and interactive effects of early weight gain and diet on infant weight status trajectories and odds for overweight at 1 year.

Methods

We conducted secondary analysis on data from two longitudinal trials with repeated anthropometric measures. One trial consisted of predominantly or exclusively breastfed (BF, n = 97) infants, whereas the other consisted of exclusively formula-fed (FF, n = 113) infants. Weight-for-length z-score (WLZ) change from 0.5 to 4.5 months was used to categorize early weight gain as slow (<-0.67; SWG), normal (-0.67 to 0.67; NWG) or rapid (>0.67; RWG).
