BACKGROUND
Childhood obesity and physical inactivity are growing global concerns, particularly in developing countries. Traditional interventions have shown limited success in fostering sustained physical activity (PA) behaviors among children. Serious games and active video games offer an engaging alternative by integrating behavior change techniques within immersive digital environments. This study evaluated the effectiveness of Naji Iriano, a culturally adapted health video game, in improving motivation, self-efficacy, and PA prioritization among children in Bushehr, Iran.
METHODS
This randomized clinical trial included 128 primary school students aged 9-12 years, who were allocated to either an intervention group (Naji Iriano) or a control group (no intervention). Assessments were conducted at baseline, 6 weeks post-intervention onset (Post-test-1), and 6 weeks post-intervention completion (Post-test-2). Data collection tools included questionnaires measuring PA motivation, self-efficacy, prioritization, and the Physical Activity Questionnaire for Children (PAQ-C). Data were analyzed using SPSS version 20, employing chi-square tests, independent t-tests, and analysis of covariance (ANCOVA) with a significance level of 0.05.
RESULTS
The adjusted ANCOVA analysis showed significant group differences. The intervention group showed significant improvements in PA self-efficacy (p < 0.001), PA prioritization (p < 0.001), and PA levels (p < 0.001) at both Post-test-1 and Post-test-2 compared to the control group. However, no significant changes were observed in body mass index (BMI) between the groups (p = 0.799). Although PA motivation increased at Post-test-1, this effect was not sustained at Post-test-2 after controlling for covariates (p = 0.968).
CONCLUSIONS
Health video games such as Naji Iriano can effectively enhance psychological and behavioral determinants of PA in children, providing a scalable, engaging strategy for obesity prevention. Future research should explore long-term adherence, emphasizing the role of parental involvement and environmental support in sustaining behavior change.
TRIAL REGISTRATION
This trial was registered in the Iranian Registry of Clinical Trials (IRCT) on 2019-01-02, registration number: IRCT20130317012830N33.
背景
儿童肥胖和身体活动不足是日益引起全球关注的问题，在发展中国家尤为如此。传统干预措施在促进儿童持续身体活动（PA）行为方面成效有限。严肃游戏和主动式电子游戏通过将行为改变技术融入沉浸式数字环境，提供了一种引人入胜的替代方式。本研究评估了一款经过文化适应性调整的健康视频游戏《纳吉·伊里亚诺》对伊朗布什尔儿童的动机、自我效能和PA优先级的改善效果。
方法
这项随机临床试验纳入了128名9至12岁的小学生，他们被分配到干预组（《纳吉·伊里亚诺》）或对照组（无干预）。在基线、干预开始后6周（测试后1）和干预结束后6周（测试后2）进行评估。数据收集工具包括测量PA动机、自我效能、优先级的问卷以及儿童身体活动问卷（PAQ-C）。使用SPSS 20版软件进行数据分析，采用卡方检验、独立t检验和协方差分析（ANCOVA），显著性水平为0.05。
结果
调整后的ANCOVA分析显示出显著的组间差异。与对照组相比，干预组在测试后1和测试后2时PA自我效能（p < 0.001）、PA优先级（p < 0.001）和PA水平（p < 0.001）均有显著改善。然而，两组间体重指数（BMI）未观察到显著变化（p = 0.799）。虽然在测试后1时PA动机有所增加，但在控制协变量后，测试后2时这种效果未持续（p = 0.968）。
结论
像《纳吉·伊里亚诺》这样的健康视频游戏可以有效增强儿童PA的心理和行为决定因素，为预防肥胖提供一种可扩展、引人入胜的策略。未来研究应探索长期依从性，强调父母参与和环境支持在维持行为改变中的作用。
