RESUMO
OBJECTIVE: To apply behavioral economics strategies (i.e., placement changes and signage) to nudge university students' healthy dining hall eating. Participants: A convenience sample of 4208 students exiting a university dining hall were asked to take a brief survey on meal selections. Methods: Three unique nudges (related to beverage, snack and dessert) were individually introduced and then removed for a week using a quasi-experimental design. Exit surveys during non-nudge and intervention periods were compared using chi-square analysis. Results: The beverage nudge significantly increased water consumption (p=.03) and the dessert nudge significantly increased healthy dessert consumption (p<.001) between comparison and intervention weeks. The snack intervention did not significantly affect snack choice. Conclusions: Simple signage interventions may be effective to encourage healthy eating behaviors in a college dining hall setting. Student health may be improved by nudging students to select healthier beverage and dessert options.
