OBJECTIVES: To evaluate the three-month effectiveness of incorporating co-creation into physical literacy intervention for weight management and physical fitness improvement in obese children.
METHODS: A parallel-group, multi-center, cluster randomized controlled trial was conducted from September to December 2024. Chinese children aged 8-12 years with obesity (Body Mass Index [BMI] ≥98th percentile) were recruited to participate in a 12-week touch rugby programme in partnership with local schools and youth-serving non-governmental organizations in Hong Kong. After obtaining parental consent, schools were randomized into intervention and control groups (1:1 ratio). The intervention group received a co-creation programme led by sports science-trained coaches, incorporating engagement and design discussions before and after sessions. The control group received standard touch rugby instruction. Interview-administered questionnaires, bioimpedance analysis, and sprint running assessment were conducted at baseline and week 12. Descriptive statistics characterized the cohort, and independent t-tests analyzed intergroup differences in BMI, body fat percentage, and sprint performance, with 95% confidence intervals (95% CI).
RESULTS: Eighty-two children (intervention: n=41; control: n=41; mean age=9.78±1.26 years; 63.4% male) participated, with baseline BMI of 24.04 kg/m² and 24.21 kg/m² in intervention and control groups, respectively. Nineteen participants (23.2%) were lost to follow-up. Post-intervention, the intervention group demonstrated significantly improved 4×10m sprint performance (mean difference=1.662s; 95% CI: 0.531-2.795). While the intervention group showed a BMI reduction (-0.181 kg/m²), the intergroup difference was not significant (mean difference=0.187; 95% CI: -1.087-1.460). No significant intergroup differences were observed in body fat percentage changes.
CONCLUSIONS: Incorporating co-creation into physical literacy intervention significantly improved physical fitness in obese children, though further investigation is warranted to establish its effects on body composition parameters.
