Developing a socio-ecological framework for promoting physical activity among Chinese children and adolescents: a Delphi–AHP study

This study is the first to establish a localized framework for PA promotion among Chinese children and adolescents, offering clear stakeholder responsibilities and weighted indicators to guide evidence-based interventions. While grounded in China's unique sociocultural setting, the methodology may inform similar efforts internationally. Future research should focus on empirical validation and development of standardized assessment tools based on this framework.
