Hypertension: comparison of self-reported information and objective measures from the first Portuguese National Health Examination Survey (INSEF)

Prémio de Melhor Poster do Dia do Jovem Investigador 2017This study compares self-reported and examination-based prevalence of hypertension using data from the Portuguese National Health Examination Survey (n=4911), that combines personal interview and clinical measurements. Logistic regression was used to identify factors associated to incorrect self-reports. Self-reports underestimated prevalence of hypertension. The accuracy of self-reports varied between population subgroups. Sex, age group, education and use of healthcare services were associated with incorrect self-reports of hypertension. Adding objective measurements to self-reported questionnaire improve data accuracy and allow better understanding of socioeconomic inequalities in health.The Portuguese National Health Examination Survey is developed as a part of the project “Improvement of epidemiological health information to support public health decision and management in Portugal. Towards reduced inequalities, improved health, and bilateral cooperation”, that benefits from a 1.500.000€ Grant from Iceland, Liechtenstein and Norway through the EEA Grants.N/
