The prevalence of childhood and adolescent obesity has increased in the last several decades, with no evidence of plateau or decrease. Infant feeding style has been found to be associated with an increased risk of overweight and obesity in childhood and adolescence. This study sought to determine if maternal body dissatisfaction was associated with infant feeding style among a cohort of non-Hispanic black mother-infant dyads. A cross-sectional preliminary study found significant associations with non-responsive feeding styles early in the postpartum period. The current study explored this association longitudinally from 3- to 18-months of infant age. Multilevel mixed effects models indicate that maternal body dissatisfaction is positively associated with restrictive-diet-quality, and negatively associated with responsive-satiety throughout the postpartum period. Early feeding interventions should be tailored toward mothers to educate on postpartum body changes, positive body image, and appropriate infant feeding practices. This association should be explored in a larger, heterogeneous sample.
