Physical activity strategies for preventing school-aged children's overweight and obesity: a systematic review

This systematic review examined physical activity recommendations and strategies within clinical practice guidelines (CPG) for preventing overweight and obesity in children aged 5-17. Eighteen guidelines from Asia, Europe, North America, Oceania, and South America were identified. Strategies were classified into five categories: individual, family, school, community, and healthcare. Most recommendations aligned with international guidelines, highlighting individual responsibility in increasing daily activity and reducing sedentary time. Families should support active lifestyles and limit screen time, while schools must provide quality physical education and activity opportunities. Communities should ensure safe facilities, and the healthcare sector is tasked with guiding, monitoring, and assessing physical activity levels. Improving clarity regarding sector responsibilities may enhance the effectiveness of CPGs in schools and other health practices, contributing to long-term reductions in childhood overweight and obesity rates.
