Abstrakt: Unlabelled: During childhood and adolescence, a game could be an effective educational tool to learn healthy eating habits. We developed Kaledo, a new board game, to promote nutrition education and to improve dietary behavior. A two-group design with one pre-treatment assessment and two post-treatment assessments was employed. A total of 3,110 subjects (9-19 years old) from 20 schools in Campania, Italy, were included in the trial. In the treated group, the game was introduced each week over 20 consecutive weeks. Control group did not receive any intervention. The primary outcomes were (i) score on the "Adolescent Food Habits Checklist" (AFHC), (ii) scores on a dietary questionnaire, and (iii) BMI z-score. At the first post-assessment (6 months), the treated group obtained significantly higher scores than the control group on the AFHC (14.4 (95 % confidence interval (CI) 14.0 to 14.8) vs 10.9 (95 % CI 10.6 to -11.2); F(1,20) = 72.677; p < 0.001) and on four sections of the dietary questionnaire: "nutrition knowledge" (6.5 (6.4 to 6.6) vs 4.6 (4.5 to 4.7); F(1,16) = 78.763; p < 0.001), "healthy and unhealthy diet and food" (11.2 (11.0 to 11.4) vs 10.4 (10.3 to 10.6); F(1,32) = 21.324; p < 0.001), "food habits" (32.4 (32.0 to 32.8) vs 27.64 (27.3 to 28.0); F(1,26) = 195.039; p < 0.001), and "physical activity" (13.4 (13.2 to 13.7) vs 12.0 (11.8 to 12.6); F(1,20) = 20.765; p < 0.001). Moreover, the treated group had significantly lower BMI z-score with respect to the controls at the first (0.44 (0.42 to 0.46) vs 0.58 (0.56 to 0.59), F(1,18) = 16.584, p = 0.001) and at the second (18 months) (0.34 (0.30 to 0.38) vs 0.58 (0.54 to 0.62), F(1,13) = 7.577; p = 0.017) post-assessments.
Conclusion: Kaledo improved nutrition knowledge and dietary behavior over 6 months and had a sustained effect on the BMI z-score. Therefore, it may be used as an effective tool in childhood and adolescence obesity prevention programs.
