3Treatment groups
Experimental Treatment
Group I: Increase ConditionExperimental Treatment1 Intervention
A parent and child will be encouraged to increase fruits and vegetables. Children will be encouraged to consume 1 cup/day and 1.5 cups/day of whole fruit, and 1.5 cups/day and 2 cups/day of vegetables for children aged 6 to 8 years and 9 to 12 years, respectively. Children will gradually work towards these goals. Parents will also work towards F&V goals, with 2 cups/day of whole fruit and 2.5 cups/day of vegetables.
Group II: Increase + Decrease ConditionExperimental Treatment1 Intervention
Families will be encouraged to increase fruits and vegetables and decrease snack foods.
Group III: Decrease ConditionExperimental Treatment1 Intervention
In the Decrease Snack Foods condition participants will reduce intake of SFs (i.e., candy, cookies, cakes, ice cream, chips, nuts) to < 3 servings/week (for children aged 6 to 12 years, the solid fats and added sugar energy limit is 840 kcals/week and the DECREASE goal will help with meeting this limit). Children and parents will gradually work towards meeting these goals and self-monitor these behaviors.
