| BMI. BMI was assessed using the formula BMI-weight(kg)/height(m²) for the classification of nutritional condition. The values found were distributed into z scores according to sex and age (0 to 19 years), considering as overweight percentiles higher than 85 and lower or iqual than 97, or score higher than z + 1 and lower or iqual than z + 2, while adolescents with percentiles higher than 97 or score lower than z + 2 and z + lower or iqual than 3 were considered obese and, above these values, as severely obese. ;Tricipital and subscapular skinfolds, arm circumference, waist circumference, neck circumference, estimated fat percentage and arm fat area. To determine the skin folds, the tricipital and subscapular skinfold was measured, in which folds that had a percentile (PCT) higher than p90 for both sexes were considered as overweight or obese. In addition to the evaluation of the isolated percentile of skinfolds, the sum of these folds was calculated, estimating the percentage of body fat (%F) using the predictive equations of Slaughter et al according to the recommendations for adolescents. The brachial perimeter was also evaluated according to the Frisancho protocol, with the percentile (PCT) maor than p908 being considered as obesity for both sexes, and the arm fat area, using the Frisancho protocol and considering excess fat values above 95. Waist circumference was obtained using the Freedman protocol in which obesity was categorized as values greater than the 90th percentile for both sexes. Neck circumference (NC) was also assessed, and we used individuals with NC higher than 32 cm and higher than 35.5 cm as cutoff points for overweight and obesity, respectively. | — |

| Lipid profile, capillary glycemia. These were obtained through the collection of blood by sample in capillaries, through the portable laboratory test or Point-of-Care-Testing, to analyze glycemia, total cholesterol and triglycerides, using the Accutrend® CGT device. Participants were fasting for 12 hours before the examination. The normal reference values were used to determine the lipid profile, total cholesterol lower than 170 mg/dL and triglycerides lower than 130 mg/dL. Cholesterol was classified as: lower than 150mg/dl; between 150 and 169 mg/dl, and higher than 170 mg/dl. Triglycerides values were classified as: lower than 70 mg/dl; from 70 to 129 mg/dl and higher than 130 mg/dl. Normal blood glucose reference values lower than 100 mg/dl were used to determine the glycemic profile. ;Systemic blood pressure. Systemic blood pressure was obtained by measuring blood pressure, using an appropriate sphygmomanometer for adolescents, according to the recommended protocol. Normal values of systolic and diastolic blood pressure were determined according to the age and height of the adolescents. | — |
