Abstract: By the methods of literature review and logical analysis, the practice and current situation of multi-body linkage for children and adolescents' physical health promotion in China is analyzed. It is believed that there exist such problems in the multi-body linkage of adolescents' physical health promotion as the softening of the effectiveness of policy implementation, the imbalance between resource supply and demand, and the diverse views from participants involved. With the lessons from foreign experience and the theory of overlapping spheres of influence, social network and social support, plus theory of synergy, a "pyramid" model of multiple linkage of children's and adolescents' physical health promotion is constructed with "4 points - 6 sides - 4 lines" as the core content. And strategies are put forward as follows: clarifying the division of rights and responsibilities in the multiple body linkage based on the principle of equality and mutual benefit; taking activity innovation as the channel to create a diversified linkage power engine; maintaining the supply and demand of diversified and linked resources based on the balance between resource supply and demand; and taking data-driven as the guide to build a multiple linkage evaluation system.
