Resumo: Disease prevention should begin in childhood and lifestyles are important riskdeterminants of cardiovascular disease. Awareness and monitoring of risk is essential in pre-ventive strategies.Aim: To characterize cardiovascular risk and the relationships between certain variables in adolescents.Methods: In a cross-sectional study, 854 adolescent schoolchildren were surveyed, mean age16.3±0.9 years. Data collection included questionnaires, physical examination, charts for 10-year relative risk of mortality, and biochemical assays. In the statistical analysis continuousvariables were studied by the Student’s t test and categorical variables by the chi-square testand Fisher’s exact test, and each risk factor was entered as a dependent variable in logisticregression analysis.Results: Physical activity was insufficient in 81% of students. The daily consumption of soup,salad or vegetables, and fruit was, respectively, 37%, 39% and 21%. A minority (6%) took ≤3and 77% took ≥5 meals a day. The prevalence of each risk factor was as follows: overweight16%; smoking 13%; hypertension 11%; impaired glucose metabolism 9%; hypertriglyceridemia9%; and hypercholesterolemia 5%. Out-of-school physical activity, hypertension and overweightwere more prevalent in males (p<0.001). Females had higher levels of cholesterol (p<0.005)and triglycerides (p<0.001). A quarter of the adolescents had a relative risk score for 10-yearcardiovascular mortality of ≥2. Overweight showed a positive association with blood pressure,changes in glucose metabolism and triglycerides, and a negative association with number ofdaily meals.
