title: [Prevalence of cardiovascular risk factors in adolescents].
abstract: The aim of this study was to determine the prevalence of cardiovascular risk factors in adolescents and to verify its association with age and gender. 644 high school students from public schools in the city of Londrina, Paraná State, Brazil, participated in the study. A two-step sampling process was used. Behavioral risk factors (physical inactivity, inadequate consumption of fruits and vegetables, and smoking) and biological risk factors (overweight and high blood pressure) were investigated. Nearly 90% of adolescents showed at least one risk factor. Inadequate consumption of fruits (56.7%) and vegetables (43.9%) and physical inactivity (39.2%) were the most prevalent risk factors. Prevalence rates for high blood pressure and overweight were 18.6 and 12.7%, respectively. Cardiovascular risk factors were more frequent among boys (PR = 1.20; 95%CI = 1.01-1.42). In conclusion, cardiovascular risk factors are a prevalent health issue among students in the city of Londrina.
