Obesity is a serious health problem for many children in the United States. Approximately 32% of US children aged 2 to 19 years have overweight or obesity (body mass index [BMI] ≥85th percentile), and nearly 8% of infants and toddlers younger than 2 years have a weight-for-length at the 95th percentile or greater,1 predisposing them to obesity.2,3 Obesity leads to serious, lifelong medical and psychosocial problems and premature death.4 These consequences disproportionately affect racial/ethnic minority groups and low-income communities, where obesity is most pronounced.5 Despite previous reports that childhood obesity has remained stable or decreased, more recent evidence shows that the prevalence of obesity and severe obesity is unfortunately increasing, especially among preschool-aged children.6
