Resumo
Given the high prevalence of hypertension in adolescents, it is important to investi-
gate alternatives for estimating the magnitude of the disease. Our objective was to
investigate the accuracy of self-reported hypertension. The study assessed partici-
pants of the Study of Cardiovascular Risk in Adolescents (ERICA). The following were
calculated: sensitivity, specificity, positive predictive value (PPV), and negative pre-
dictive value (NPV). The associations between inaccurate self-reporting and socio-
economic factors were investigated. The accuracy of self-reported hypertension had
a sensitivity of 7.5% (95% CI, 6.9-8.2), a specificity of 96.6% (95% CI, 96.5-96.7), a
PPV of 18.9% (95% CI, 17.4-20.5), and a NPV of 90.8% (95% CI, 90.6-91.0). The prev-
alence of inaccurate self-reported hypertension was smaller among girls (PR 0.68;
95% CI, 0.55-0.83) and younger boys (PR 0.68; 95% CI, 0.54-0.86) who were attend-
ing private schools. The use of self-reported hypertension was not a good strategy
for investigating the hypertension in adolescents.
