Childhood obesity is more than a number: its risk is tied to health disparities, access to healthy foods, and the daily routines of families and communities. This page maps how prevalence and outcomes vary by region and highlights what works in care, from family-based behavioral programs to intensive interventions. We also connect obesity to major health effects—like type 2 diabetes, hypertension, fatty liver disease, and sleep apnea—while examining the costs for U.S. families and health systems.
