The HEALTHY intervention program consisted of 4 intervention components:


The integration of all of the components enhanced the accomplishment of the targeted goals of:

  • Increasing water consumption.
  • Substituting water for added sugar beverages.
  • Drinking water for health, nutrition, and hydration.
  • Choosing healthier foods and drinks for meals and snacks.
  • Substituting nutrient dense, lower calorie foods for low nutrient, higher calorie foods.
  • Applying self-monitoring, goal setting, and problem solving to increase intake of water, fruits, and vegetables.
  • Increasing movement and accumulation of time spent being active.
  • Decreasing time spent in sedentary behavior.
  • Substituting physical activity for sedentary behavior.
  • Applying self-monitoring, goal setting, and problem solving to increase physical activity and decrease sedentary behavior.

The intervention was delivered over 5 semesters across the 6th, 7th, and 8th grades of middle school, and each semester targeted a theme:

1. Winter/Spring 2007 6th Grade Water versus Added Sugar Beverages
2. Fall 2007 7th Grade Physical Activity versus Sedentary Behavior
3. Winter/Spring 2008 7th Grade High Quality versus Low Quality Food
4. Fall 2008 8th Grade Energy Balance – Energy In/Energy Out
5. Winter/Spring 2009 8th Grade Strength, Balance, and Choice for Life


Every theme involved each of the intervention components, so the intervention is structured as a 5-by-4 matrix.
