Early maternal feeding practices: Associations with overweight later in childhood

Current understanding of the impact of maternal feeding practices on weight outcomes in young children remains unclear given equivocal longitudinal study outcomes.

To determine whether feeding practices used by mothers when their child was less than 2 years of age were related to overweight status at ages 3.5 and 5 years in a large cross-country sample; and investigate whether these associations were moderated by weight status in early life.

Data from mother-child dyads participating in four childhood obesity prevention trials across Australia and New Zealand were pooled (n = 723). Each trial administered items from the Comprehensive Feeding Practices Questionnaire (CFPQ) to mothers when infants were approximately 20 months of age, measuring food as a reward, modelling, restriction for health, pressure to eat, and emotion regulation. Poisson regression was used to determine risk ratios (RR) for overweight (BMI z-score ≥85th percentile) at 3.5 and 5 years by CFPQ scores.

Greater use of emotion regulation at 20 months of age predicted higher risk for overweight at 3.5 and 5 years (RR = 1.19 and 1.28, respectively), while restriction for health predicted lower risk for overweight at 5 years (RR = 0.88). Child's weight status at 20 months moderated the association between pressure to eat and overweight risk at 5 years, such that those who were not overweight at 20 months of age had reduced risk of overweight associated with the use of pressure to eat (RR = 0.68) but those who were overweight had an increased risk (RR = 1.09).

Early maternal feeding practices are related to a child's later risk of overweight.
