Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find improvements in executive function by decreasing response time and increasing accuracy (correct answers) assessed by the Stroop Test, at the beginning of the study, at the end of the intervention (end of the semester) and at the end of the next semester (follow up) after completion of the intervention.;It is expected to find decreased use of screen equipment and decreased sitting time during the day measured through the validated questionnaire PeNSE (National School Health Survey), at the beginning of the study, at the end of the intervention (end of the semester) and at the end of the next semester (follow up) after completion of the intervention.;It is expected to find improvements in food intake that will be measured through the validated questionnaire PeNSE (National School Health Survey), at the beginning of the study, at the end of the intervention (end of the semester) and at the end of the next semester (follow up) after completion of the intervention. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find a reduction in systemic resting blood pressure, measured by a digital sphygmomanometer (Omron 705-IT), calibrated and certified by the National Institute of Metrology, Standardization and Industrial Quality - INMETRO. A standardized technique will be used according to the procedure described in the 7th Brazilian Hypertension Guidelines and will be classified according to the American Academy of Pediatrics, which takes into account gender and age adjusted for the adolescent's height / age percentile. These measures will be evaluated at the beginning of the study, at the end of the intervention (end of the semester), and at the end of the following semester (follow up) after the conclusion of the intervention.;It is expected to find improvements in the biochemical parameters: fasting glucose, fasting insulin, lipid profile (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides), inflammatory markers (interleukin-10 and Tumor Necrosis Factor - Alpha) and markers of stress oxidative (glutathione peroxidase and malonaldehyde). Determination of serum concentrations of biochemical parameters will be performed by enzymatic-colorimetric assays and determinations of inflammatory and oxidative stress markers will be performed by ELISA (Enzyme Linked ImmunonoSorbent Assay) and high performance liquid chromatography (HPLC), respectively. These measures will be evaluated at the beginning of the study, at the end of the intervention (end of the semester), and at the end of the following semester (follow up) after the conclusion of the intervention.;Improvements in the obesogenic environment are expected to be validated by the Family Eating and Activity Habits Questionnaire (FEAHQ-R). Adolescents and their parents will answer questions regarding the identification and monitoring of behaviors and associated factors that facilitate the development of obesity within the family. These measures will be evaluated at the beginning of the study, at the e | — |
