 The study aimed to estimate the prevalence of arterial hypertension and obesity in Brazilian adolescents, as well as the population-attributable fraction of hypertension that is due to obesity. Data from participants in the Brazilian study of cardiovascular risks in adolescents, Erika, was evaluated, which included 73,399 students aged 14.7 years on average. The prevalence of hypertension was found to be 9.6 percent, with the lowest being in the north and northeast regions and the highest in the south region. The prevalence of obesity was 8.4 percent, which was lower in the north region and higher in the south region. Obese adolescents had a higher prevalence of hypertension than overweight or utrophic adolescents. The study found that the fraction of hypertension attributable to obesity was 17.8 percent. Overall, the study highlights the importance of controlling obesity in reducing the prevalence of hypertension among Brazilian adolescents.
