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.
本研究的目的是确定青少年心血管危险因素的患病率，并验证其与年龄和性别的关联。来自巴西巴拉那州隆德里纳市公立学校的644名高中生参与了该研究。采用了两步抽样过程。对行为危险因素（身体活动不足、水果和蔬菜摄入不足以及吸烟）和生物危险因素（超重和高血压）进行了调查。近90%的青少年至少有一个危险因素。水果（56.7%）和蔬菜（43.9%）摄入不足以及身体活动不足（39.2%）是最普遍的危险因素。高血压和超重的患病率分别为18.6%和12.7%。心血管危险因素在男孩中更为常见（PR = 1.20；95%CI = 1.01 - 1.42）。总之，心血管危险因素是隆德里纳市学生中普遍存在的健康问题。
