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.
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.
本研究旨在复制棋盘游戏 Kaledo 在改善营养知识和改变中、高中生饮食行为方面的有效性，探究其在年龄更小的（7-11 岁）小学生中的作用。
共招募了来自 10 所学校的 1313 名儿童参与本研究。参与者被随机分为两组：（1）治疗组，玩 Kaledo 超过 20 次；（2）无干预组。两组均在基线（治疗前）和两次随访评估（8 个月和 18 个月）时进行了人体测量。所有参与者均在每次评估时完成了一份关于身体活动的问卷和一份为期一周的食物日记。主要结局指标为：（i）BMI z 评分，（ii）身体活动评分，和（iii）饮食问卷评分。治疗组在 8 个月时的 BMI z 评分显著低于对照组。治疗组在两次随访时的自我报告身体活动频率和持续时间也显著高于对照组。此外，治疗组健康食品的摄入量显著增加，垃圾食品的摄入量显著减少。
本研究结果证实了 Kaledo 在小学生中的有效性，它可以作为儿童肥胖预防计划中一种有用的营养工具。
• Kaledo 是一种新的教育棋盘游戏，旨在提高营养知识，促进健康的生活方式。• 在坎帕尼亚地区（意大利）进行的两项聚类随机试验中，我们表明 Kaledo 可以提高营养知识和饮食行为，并对 9-14 岁在校儿童的 BMI z 评分产生积极影响。• Kaledo 可作为中、高中生肥胖预防计划的有效工具。
• 研究 Kaledo 对年龄更小的（7-11 岁）小学生的影响，表明 Kaledo 可能是 7 岁以下儿童肥胖预防计划的有效工具。
