Childhood Obesity Prevention
Most US children spend an average of 6 to 7 hours a day at school, which is a large part of their waking hours.1–3 Thus, schools are a priority setting for preventing childhood obesity,4–7 a health condition that affects nearly 1 in 5 young people of school age (6 to 19 years) in the United States.8
A comprehensive approach is most effective at addressing childhood obesity in schools, especially for elementary and middle school students.9,10 Scientists know less about what school-based obesity prevention approaches are effective for teenagers.9,10 A comprehensive approach means addressing nutrition and physical activity in schools and involving parents, caregivers, and other community members (e.g., pediatricians, after-school program providers). This kind of approach aims to support the health and well-being of all students. It does not single out students according to their weight status. To avoid embarrassing or shaming students, schools should not emphasize physical appearances or reinforce negative stereotypes about obesity.11
The WSCC Model and Childhood Obesity Prevention
Schools can apply the Whole School, Whole Community, Whole Child (WSCC) model to guide their approach to preventing childhood obesity and supporting students with obesity. The WSCC model highlights how a child’s emotional, physical, and academic development requires multiple components, including:
- Physical education and physical activity.
- Nutrition environment and services.
- School health services to support physical, psychological, and emotional health.
- Family and community engagement.
Addressing these areas can help children achieve and maintain a healthy weight and attitude about weight.
CDC’s School Health Guidelines present evidence-based guidelines and strategies for putting a comprehensive approach in place. Strong state and local wellness policies can demonstrate schools’ commitment to these guidelines and a comprehensive approach to support physical activity and healthy eating. Research has linked these kinds of policies with improvements in the nutrition of foods and beverages sold and served in schools12 and opportunities for physical activity.13
