Effectiveness of a Behavior-and Age-Specific Nutrition Education Intervention to Promote Nutrition Knowledge and Preference for Fruits and Vegetables among Elementary School Children

Abstract

ABSTRACT Background Lack of nutrition knowledge, low preference for fruits and vegetables (F&V), and underdeveloped taste are recognized as modifiable influencers of children’s F&V intake. Purpose To assess the effectiveness of a behavior-and age-specific nutrition education intervention to improve nutrition knowledge and preference for F&V among elementary school children. Methods In a quasi-experimental pre-and posttest assessment designed study, a six-week nutrition education intervention (including class-based nutrition education, hands-on activities, cooking demonstrations, and tasting) was implemented at four elementary schools. Nutrition knowledge and preference for F&V were evaluated at baseline and after the intervention. Wilcoxon signed-rank test was carried out to examine the differences between baseline and post-assessment. Results A total of 115 children (3rd- 5th grade) completed both baseline and post-assessment. After the intervention, participants showed a significant improvement in nutrition knowledge (mean [± sd] change score: 7.6 ± 3.7, P < .001). A significant improvement in F&V preference (Ps < .001) was found among the participants after the intervention. Discussion An age-and behavior-focused nutrition education intervention can improve children’s nutrition knowledge and F&V preference. Translation to Health Education Practice: This nutrition education curriculum can be implemented for the child population (age-specific groups) by adapting cultural priorities in nutrition lessons and cooking recipes.
