dc.description.abstractINTRODUCTION: Disease prevention should begin in childhood and lifestyles are important risk determinants of cardiovascular disease. Awareness and monitoring of risk is essential in preventive 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 age 16.3±0.9 years. Data collection included questionnaires, physical examination, charts for 10-year relative risk of mortality, and biochemical assays. In the statistical analysis continuous variables were studied by the Student's t test and categorical variables by the chi-square test and Fisher's exact test, and each risk factor was entered as a dependent variable in logistic regression 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 ≤3 and 77% took ≥5 meals a day. The prevalence of each risk factor was as follows: overweight 16%; smoking 13%; hypertension 11%; impaired glucose metabolism 9%; hypertriglyceridemia 9%; and hypercholesterolemia 5%. Out-of-school physical activity, hypertension and overweight were 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-year cardiovascular mortality of ≥2. Overweight showed a positive association with blood pressure, changes in glucose metabolism and triglycerides, and a negative association with number of daily meals. CONCLUSIONS: The results demonstrate the need for action in providing and encouraging healthy choices for adolescents, with an emphasis on behavioral and lifestyle changes aimed at individuals, families and communitiespor
