%X OBJECTIVE: Our aim was to identify independent determinants of rapid weight gain in infants at 3-4, 6, and 12 months of age.
METHODS: A cohort study was conducted on Mexican term infants in public and private settings between March 2021 and May 2023. Rapid weight gain was defined as a ≥0.67 SD change in weight-for-age-Z-score from birth to 3-4, 6, and 12 months of age. Maternal and infant characteristics were described, and infant feeding practices, appetitive traits, weight, and length were analysed at 3-4, 6, and 12 months of age. Rapid weight gain predictors were determined using generalised linear regression models.
RESULTS: In total, 168 infants were recruited (55% boys). Small-for-gestational-age status increased rapid weight gain risk 1.5 times, whereas large-for-gestational-age status represented a 20%-30% decrease. Slowness in eating decreased the risk by 10%. Protective factors were older maternal age and higher educational level, whereas formula feeding, early complementary feeding, greater food enjoyment, and satiety responsiveness increased the risk.
CONCLUSIONS: Small for gestational age, slowness in eating, and feeding practices can be rapid weight gain predictors across the first year of life.
