RESUMEN

The board game Kaledo was proven to be effective in improving nutrition knowledge and in modifying dietary behavior in students attending middle and high school. The present pilot study aims to reproduce these results in younger students (7-11 years old) attending primary school. A total of 1313 children from ten schools were recruited to participate in the present study. Participants were randomized into two groups: (1) the treatment group which consisted of playing Kaledo over 20 sessions and (2) the no intervention group. Anthropometric measures were carried out for both groups at baseline (prior to any treatment) and at two follow-up post-assessments (8 and 18 months). All the participants completed a questionnaire concerning physical activity and a 1-week food diary at each assessment. The primary outcomes were (i) BMI z-score, (ii) scores on physical activity, and (iii) scores on a dietary questionnaire. BMI z-score was significantly lower in the treated group compared to the control group at 8 months. Frequency and duration of self-reported physical activity were also significantly augmented in the treated group compared to the control group at both post-assessments. Moreover, a significant increase in the consumption of healthy food and a significant decrease in junk food intake were observed in the treated group. CONCLUSION: The present results confirm the efficacy of Kaledo in younger students in primary schools, and it can be used as a useful nutritional tool for obesity prevention programs in children. What is Known: • Kaledo is a new educational board game to improve nutrition knowledge and to promote a healthy lifestyle. • In two cluster randomized trials conducted in Campania region (Italy), we showed that Kaledo could improve nutrition knowledge and dietary behavior and have a positive effect on the BMI z-score in children with age ranging from 9 to 14 years old attending school. • Kaledo may be used as an effective tool for obesity prevention programs in middle and high school students. What is New: • Investigating the effects of Kaledo on younger primary school children (7-11 year olds), Kaledo could be an effective tool in obesity prevention programs for children as young as 7 years old.

RESUMEN

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.

RESUMEN

The impairment of brain functions during aging could be prevented by an increase in antioxidative defenses. In fact, dietary manipulation with antioxidants or with antioxidant-rich extracts from vegetables and fruit can ameliorate age-associated behavioral alterations. Moreover, dietary supplements of antioxidants can reverse the age-dependent impairment to sustain long-term potentiation (LTP). There is evidence that fresh fruit could be more effective than antioxidant supplements or fruit and vegetable extracts but the effect of a diet enriched in fresh fruit on brain aging process has not been investigated until now. The aim of the present study was to verify whether dietary manipulation with fresh apples could influence age-induced changes in motor and emotional behavior and in LTP in rats. Groups of aged and young rats were fed with a standard diet or a diet supplemented with fresh apples of annurca variety for 10 weeks and assessed for behavioral performance in the open field and elevated plus maze tests and for the ability to sustain LTP. The brains were then removed, histochemically stained for superoxide dismutase (SOD) and SOD activity was measured by computer-assisted image analysis. The aged rats fed with the enriched diet showed a significant decrease in the anxiety level. Moreover, they improved in the ability to sustain LTP, reaching the level of the young rats. SOD activity was increased in the aged rats fed with the standard diet whereas SOD activity in the hippocampus of the aged rats treated with annurca apple was at the level of the young animals. These results suggest that a diet rich in annurca apple could have an important role in health-care during aging.
