Nutrition Clinical Trial
Official title:
Using Reinforcement Schedules to Improve Carotenoid Levels, Reduce Fruit and Vegetable Waste, and Increase School Lunch Participation in El Paso
Using small monetary rewards to reinforce healthy behaviors, such as the consumption of fruits and vegetables (F&V), the investigators tested fixed and variable reinforcement schedules in three middle schools. The investigators measured carotenoid levels, as a biomarker of F&V intake, and F&V waste over the intervention time frame. The investigators also tracked the school lunch participation rates over time.
