The present scoping review protocol aims to investigate the complex factors associated with the active and sedentary behaviors in young people applying Bronfenbrenner's bioecological theory. The study will be carried out based on the steps proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews. The review question was formulated with the help of the ‘PCC’ strategy, such that: a) population: studies carried out with children and adolescents (aged between 5-17 years) and with any health condition will be considered eligible; b) concept: studies in the area of physical activity (PA) and/or sedentary behavior (SB) that used Bronfenbrenner's theory and the PPCT method; c) context: studies conducted in any context will be included. The search for studies will be carried out in the following databases: PubMed, Scopus, SPORTDiscus, Web of Science, PsycINFO, ERIC, and Scielo. The processes of identifying and removing duplicates, as the evaluation of titles and abstracts will be carried out in Rayyan by two independent and blind reviewers. The research data can guide political agents in the implementation of public policies and the development of work policies that encourage the reduction of SB and the increase of PA in children and adolescents.
