CARDIOVASCULAR RISK AND ASSOCIATED FACTORS IN ADOLESCENTS.

BACKGROUND
changes in lifestyle are related to early exposure of adolescents to comorbidities associated with cardiovascular disease. These conditions may have consequences in adulthood.


OBJECTIVE
to determine the prevalence of cardiovascular risk and its associated factors in the three phases of adolescence.


METHODS
a cross-sectional study involving adolescents 10-19 years old in the city of Viçosa distributed in three stages. We evaluated laboratory tests, body mass index classified into Z-score according to gender and age, and the percentage of body fat classified by gender. We used the chi-square test, chi-square partition with Bonferroni correction and Poisson regression. The significance level was α < 0.05. The project was approved by the UFV Committee of Ethics and Research with Humans.


RESULTS
overweight, excess body fat, lipid profile, sedentary behavior, and history of CVD in family were the most prevalent cardiovascular risk factors among adolescents. The adolescents had higher rates of overweight and excess fat. As for the stages, the first one showed a higher percentage of individuals with sedentary behavior, overweight, total cholesterol and LDL in comparison with other stages. Individuals with changes in nutritional status were more likely to develop hypertension, changes in total cholesterol, LDL, triglycerides, insulin, HOMA and low HDL when compared to healthy individuals.


CONCLUSIONS
the cardiovascular risk factors have been observed in younger and younger individuals and are important factors to identify a population at risk.
