Overview of systematic reviews of health interventions that aim to prevent and treat overweight and obesity among children

Background: Childhood overweight and obesity is a global public health issue. Although there is evidence of a reduced prevalence in some countries, there is still much controversy about the efficacy of health interventions that aim to prevent and treat obesity in this specific population. The objective of the present study is to develop an overview of systematic reviews (OSRs) that assesses the effects of school-based, family, and multi-component health interventions for the prevention and treatment of obesity, change in physical activity, dietary, and/or hydration behaviors, and change in metabolic risk factors in school-aged children. Methods: This protocol was developed using the methodology proposed by Cochrane. It outlines a comprehensive search in 12 electronic databases to identify systematic reviews of health interventions, including studies that evaluate and how to prevent and/or treat overweight and/or obesity in children aged 6 to 12 years. The risk of bias of the included Systematic Reviews will be assessed with the ROBIS tool. Discussion: Since the OSRs methodology's purpose is only to harmonize evidence from open access publications, ethical consent is not necessary for the present protocol. In terms of diffusion, a paper will be submitted for publication in a scientific journal to describe the main results obtained through the OSRs.

The objective of this study is to evaluate the effects of school-based, family, and multi-component health interventions on childhood overweight and obesity through overview of systematic reviews (OSRs). A comprehensive search will be conducted in 12 electronic databases to identify relevant systematic reviews, and the risk of bias will be assessed using the ROBIS tool. The main results obtained through OSRs will be published in a scientific journal.
