  1. INSEF – Portuguese Health Examination Survey, INS2014 – National Health Interview Survey 2014, MIME – Misclassification error correction
  2. athe age groups 25–34 years and 34–44 years were aggregated in further analyses given a low number of participants reported hypertension
  3. bEducational level was grouped according the 2011 International Standard Classification of Education (ISCED) into four categories
