Target Behavior: Healthy Eating
Intervention Type: Direct Education, PSE Change, Social Marketing
Intervention Reach and Adoption
Target Audience: Elementary School, Middle School
- School self-assessment: Each school created a Nutrition Advisory Group to assess their environment and created an action plan.
- Nutrition Education: An interdisciplinary educational component was designed to teach children how dietary intake and physical activity are linked to overall health. The goal was to provide 50 hours of nutrition education per student every year.
- Nutrition Policy: All beverage options were changed to align with USDA Dietary Guidelines and had to be 100% fruit juice, low-fat milk, or water. Snacks had to contain ≤7 g of total fat, 2 g of saturated fat, 360 mg of sodium, and 15 g of sugar per serving, eliminating the sale of previously sold snacks like candy and chips.
- Social Marketing: Slogans and characters were developed through student focus groups to promote healthy eating messages. Raffle tickets were given out to children who purchased healthy snacks and beverages and raffle winners received prizes.
- Parent Outreach: Nutrition educators reached out to parents using a variety of strategies to encourage parents to reinforce the health behaviors children learn in schools and to purchase healthy snacks for the home.
This toolkit reviews the link between child health and schools, provides an overview of SNPI, and provides detail on each program component for those who would like to create a program for the children in their community.
