  1. aElevated Blood pressure was defined as a systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg
  2. bComparison by unpaired t-test or χ2 versus Normal BP
  3. cElevated blood glucose ≥ 100 mg/dL after minimum 6-h fast
  4. dRef: reference category
  5. Table shows results from the multivariate analysis assessing independent participants’ characteristics associated to the elevated BP, comparison between each time the normal BP group versus elevated BP, versus poorly controlled BP and versus new discovered cases BP groups
