O29 Development of a Virtual Reality Avatar Software Program to Prevent Obesity in Children From Low-Income Communities

Abstract

Background Many families from low-income communities lack access to evidence-based nutrition education opportunities. Thus, we developed a virtual reality avatar program to provide parents and children with tailored nutrition education on healthy snacking. Objective To assess the effectiveness, usability, and applicability of an innovative virtual reality avatar software to improve healthy snacking behaviors in children. Study Design, Setting, Participants Qualitative methods were used for product development user testing. The research focused on children (ages 5-10) from low-income communities in North Carolina. First, children from a youth food summit provided anonymous written feedback on their reactions to the program. Second, this initial feedback was used to modify the program, which was then given to parent-child dyads (n = 15) who were observed using the program and then completed an in-depth semi-structured interview about their experiences. Eligibility for the second phase included being English speaking, low-income (federal benefit eligible), and having a child between ages 5-10. All participants for the observations/interviews were African American and received a gift card for their participation. Measurable Outcome/Analysis Interest in using the program, usability, and overall perceptions were determined with a Thematic analysis approach in Atlas Ti. Results The anonymous written feedback from children was mostly positive. Most children found the program to be “cool,” “fun,” and “helpful.” Children suggested changing the voice of the avatar, adding more pictures and interaction (eg, gamifying), and allowing personalization of the avatar. In the interviews, children stated they were excited about interacting with the avatar and parents liked that it modeled healthy behaviors. The program helped to foster dialogue between children and parents, and the avatar's probes helped parents learn new information about their children's preferences/behaviors. Conclusion The virtual reality avatar program appears to be a promising nutrition education approach for children. Evaluation of impact on dietary behaviors is needed.
