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.engPortuguese National Health Examination SurveyHypertensionPrevalenceSelf-reportINSEFEstados de Saúde e de Doençaconference object
