Given the high prevalence of hypertension in adolescents, it is important to investigate alternatives for estimating the magnitude of the disease. Our objective was to investigate the accuracy of self-reported hypertension. The study assessed participants of the Study of Cardiovascular Risk in Adolescents (ERICA). The following were calculated: sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The associations between inaccurate self-reporting and socioeconomic 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 prevalence 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 attending private schools. The use of self-reported hypertension was not a good strategy for investigating the hypertension in adolescents.
