Detailed description: The objective of this study was to determine the efficacy of the iGrow Readers curriculum in changing diet and physical activity knowledge among preschool-aged children. The secondary objective of this study was to better understand the relationship between diet and physical activity related outcome variables in preschool aged children and their primary caregivers.

iGrow Readers was created to support literacy development among preschoolers, while promoting nutrition and physical activity messages. This program utilizes the social cognitive theory because it focuses on different environments influencing individual's behaviors and knowledge acquisitions, primarily through observing others within the context of social interactions and experiences. Developmentally appropriate preschool-aged children books, including relevant Native American books, facilitate the themes of healthy physical activity and nutrition practices. The program, a 6-8-week educational curriculum, helps young children understand the benefits of making healthy decisions involving nutrition and physical activity.
