Abstract

ObjectiveGames promoting nutrition education are helpful tools to improve nutrition knowledge. Healthy Foodie is an interactive web-based nutrition game for Filipino children. This study aimed to determine the effectiveness of Healthy Foodie on the nutrition knowledge of children aged 7 to 10 years old.MethodologyThis study had 2 phases. In Phase 1, we developed and validated the Healthy Foodie nutrition game application and Nutrition Knowledge Questionnaire involving 46 participants. The Nutrition Knowledge Questionnaire was divided into 2 15-item questionnaires: Part 1 pertained to Food Group Knowledge and Part 2 on Food Frequency Knowledge. Phase 2 was the implementation of the game and questionnaire. This was a randomized controlled trial conducted in two elementary schools in Manila, involving 360 participants divided equally into control and experimental groups.ResultsFor Phase 1, internal consistency of the questionnaire using the Kuder-Richardson Formula 20 was 0.75 for part 1 and 0.70 for Part 2. In Phase 2, comparing the adjusted posttest mean Food Group Knowledge scores, there was statistically higher score (F=111.84, p=0.0001) in the experimental group (11.57±0.20) compared to the control (8.51±0.20). In the adjusted posttest mean Food Frequency Knowledge scores, there was a statistically higher score (F=56.12, p=0.0001) in the experimental group (10.70±0.15) compared to the control (9.07±0.15).ConclusionA nutrition game-based intervention such as Healthy Foodie is effective as a reinforcement intervention to previous standard nutrition education of school-aged children.
