Objective: To assess the effectiveness of an educational intervention to improve children's knowledge of the sugar content of food and beverages.
Methods: Cluster-randomized, controlled trial with 268 children (aged 10-12 years) from 14 primary schools in Aberdeen, Scotland. The intervention group received 2 interactive classroom sessions about sugar. A questionnaire to assess knowledge was completed at baseline and 4, 10, and 34 weeks post-intervention. Dietary intake was assessed by food frequency questionnaire at baseline and on weeks 10 and 34.
Results: After the intervention, the intervention group demonstrated greater knowledge of sugar than did the control group (P < .001), which was sustained at week 34 (P < .001). Dietary intakes of sugar did not change postintervention. Pre-intervention children underestimated the sugar content of fruit-based beverages.
Conclusions and Implications: Children's knowledge of sugar in food and beverages is limited but can be improved through a simple educational intervention. Further intervention would be needed to encourage a change in dietary intake.
