Multi-component school-based obesity prevention interventions involve educational, environmental, and behavioral activities and typically address both physical activity and nutrition before, during, or after school. Multi-component school-based interventions typically include healthy living and nutrition education classes, enhanced physical education and increased physical activity opportunities, school-wide promotion of healthy food options and food environment improvements, capacity building and professional support for teachers and staff, and family education and support. Specific components vary by program1, 2.

Evidence of Effectiveness
There is strong evidence that multi-component school-based obesity prevention programs increase physical activity3, 4, 5, and improve dietary habits6, 7, 8. Such programs also improve weight status when implemented with high intensity and for long durations2, 9, 10, 11, 1, 12. However, there is significant variability in program design and effect13, 14, 15. Additional evidence is needed to confirm long-term effects.
In general, multi-component school-based obesity prevention programs are more successful than single component programs1, 12, 11, 7, 16, 17, 10. Multi-component school-based obesity prevention programs that include both a nutrition and physical activity focus appear more effective than one-sided programs10, 18. Such programs can also reduce blood pressure more effectively than single-focus interventions19. Specific components of school-based obesity prevention programs may be more effective for some age groups than others16.
Multi-component school-based interventions with durations of a year or more, high levels of intensity, and parent and community involvement have the greatest effects on weight-related outcomes9, 10, 20. Such interventions may also be more effective among children and adolescents who are overweight or obese20. Multi-component school-based obesity prevention programs’ effects on body mass index (BMI) outcomes vary based largely on program duration and intensity. Many programs demonstrate significant positive effects1, 6, 13, 9, 21, others show no significant effect4, 13, 14, 22, and, in rare instances, programs demonstrate negative effects5. The effect on weight outcomes of multi-component interventions that focus on physical activity also depends on the duration and intensity of the intervention19, 23, 24. Improvements to the school food environment, implemented as part of multi-component nutrition education interventions, have been shown to reduce or maintain the rate of overweight or obese children15. In some cases, school-based multi-component interventions appear to work better for girls than boys25.
School-based physical activity interventions, as part of an obesity prevention program, can benefit executive functions of children who are overweight or obese26. School-based dietary components of multi-component interventions may also benefit general school achievement for obese children26. Multi-component interventions with a specific focus on self-esteem can improve self-esteem for overweight or obese adolescents; interventions without such a focus improve weight status but not self-esteem21.
Multi-component school-based interventions can improve weight outcomes for African-American children and youth, especially when programs address both physical activity and nutrition and have a long duration27. Such interventions appear to be most successful when they are designed as joint parent-youth interventions, include supportive relationships between African-American mentors and youth, emphasize healthy activities that youth enjoy, and are culturally-adapted28. Targeted multi-component obesity prevention interventions may also benefit Latino children who are overweight or obese29.
Surveys suggest that obesity prevention programs are not associated with increases in unhealthy weight control behaviors such as fasting. Programs that specifically include the topic of eating disorders in their curricula are associated with a reduction in the percent of students reporting using unhealthy or extreme weight control behaviors30.
Impact on Disparities
Multi-component school-based obesity prevention programs that include health education classes, enhanced physical education, and promotion of healthy food options are used in all 50 states. Physical Activity and Teenage Health program31; Sports, Play and Active Recreation for Kids program32; and the Eat Well and Keep Moving program33 are three examples. The 5-2-1-0 childhood obesity prevention program is another example of a multi-component intervention for improving diet, increasing physical activity, and reducing screen time; the program is often implemented in school and community settings and encourages developing daily habits that include 5 servings of fruits and vegetables, 2 hours or less of screen time, 1 hour or more of physical activity, 0 sugary drinks, and increased water consumption. The 5-2-1-0 program started in Maine34, and has expanded to cities and states across the country, including Florida35; New Hampshire36; Baton Rouge, LA37; Chesterfield County, VA38; and Palo Alto, CA39.
As of 2014, 35 states, Washington DC, and Puerto Rico have legislation that supports school-focused policies for healthy eating and physical activity, including many components of successful multi-component obesity prevention interventions40.
