Childhood Overweight & Obesity
Childhood obesity is a serious health problem in the United States where 1 in 5 children and adolescents are affected. Some groups of children are more affected than others, but all children are at risk of gaining weight that is higher than what is considered healthy.
Obesity is complex. Many factors can contribute to excess weight gain including behavior, genetics and taking certain medications. But societal and community factors also matter: child care and school environments, neighborhood design, access to healthy, affordable foods and beverages, and access to safe and convenient places for physical activity affect our ability to make healthy choices.
Every child deserves a healthy start in life. Learn what parents and caregivers can to do help prevent obesity at home, how healthcare systems can help families prevent and manage childhood obesity, and what strategies communities can use to support a healthy, active lifestyle for all.
