Healthy lifestyle promotion in primary schools through the board game Kaledo: a pilot cluster randomized trial
AbstractThe 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.
