**5. Conclusions**

Research regarding interventions and treatment for children and adolescents with overweight or obesity is still of great interest to researchers over the world. By applying LDA, we identified ten major topics research related to the intervention and treatment of overweight and obesity among children and adolescents. Notably, is the development in the number of publications that mentioned family-based, school-based, and community-based. Besides, the active collaboration from the LMICs' side, and the support as well as further research on treatments and intervention from developed countries, are needed to reduce the increasing prevalence of childhood obesity.
