SUMMARY:

Adolescence is a period marked by several neuroendocrine changes that influence brain development and behavior. Adolescents are more likely to adopt risky behaviors in their lifestyle, including sedentary behavior (SB). In this sense, intervention studies have sought to develop efficient strategies to educate adolescents to adopt a healthy lifestyle. However, although promising actions can be identified in the literature, the real mechanism that acts in the regulation of behavior in adolescents seems to be associated with the neurotrophin Brain-Derived Neurotrophic Factor (BDNF), and studying how risk behaviors influence its secretion are of great relevance to develop more effective interventions. Therefore, the objective of this thesis is to describe the theoretical foundation and planning of a school-based multicomponent intervention with combined actions to promote physical activity, reduction of sedentary behavior and food and nutrition education, and the possible consequences for cognitive performance and adolescent health. The methodology of this thesis is described in the format of a collection of articles and was divided into four stages. The first stage describes a systematic review that was developed during the theoretical foundation studies for planning the intervention of the Attitude, Movement and Choices for a Healthy Life Program (AME Program), and it was possible to identify the need to implement a specific training stage for physical education teachers. The second stage, which was motivated by the outcomes of the COVID-19 pandemic, presents an opinion article on the effects of SB on adolescents’ health and describes in a preliminary way some of the strategies of the AME Program that can be used by school teachers in order to reduce sedentary time during the classes and the stay in the school environments.In stage three was detailed the methodology of a systematic review that will be developed with the objective of investigating the relationship between SB and BDNF in adolescents. The methodological protocol for the review has been submitted to the International Prospective Register of Systematic Reviews (PROSPERO) and will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the recommendations outlined in the Cochrane Handbook for Systematic Reviews of Interventions. The fourth step refers to the description of the theoretical basis and methods addressed in the sedentary behavior axis of the AME Program intervention, which was registered on the Brazilian Registry of Clinical Trials platform under the number RBR-86xv46. The results of this thesis are based on the production of studies and, considering that part is still in the writing phase, the appreciation and suggestions of the examining board will contribute to the methodological and scientific quality of the articles. It can be said that the AME Program is an integrated, sustainable and low-cost proposal, with great potential to produce benefits inlifestyle, cognitive performance and health of adolescents. Finally, the results of these studies will strengthen evidence-based practice in research aimed at promoting health in the school context.
