Hypertension: systolic pressure≥140 or diastolic pressure≥90 or currently taking blood pressure-lowering medication.
Awareness, treatment and control were assessed among those with hypertension.
Aware: Self-report of having been diagnosed as hypertensive by a doctor or nurse, excluding women diagnosed during pregnancy (England); Self-reported BP medication use in the past month or self-reported high-blood pressure (Canada); Self-report of having been diagnosed as hypertensive by a doctor or nurse, excluding women diagnosed during pregnancy (USA).
Treated: Taking medication to lower blood pressure recorded by the nurse (England); taking medication to lower blood pressure, self-report (Canada, USA).
Treated and controlled: taking medication to lower blood pressure and DBP <90 and SBP<140 mm Hg.
Treated and uncontrolled: taking medication to lower blood pressure and DBP >=90 or SBP >=140 mm Hg.
Aware, not treated: Self-reported of having been diagnosed as hypertensive by a doctor or nurse, not taking medication to lower blood pressure (ENGLAND); Self-reported of having been told by a healthcare provider that they have high blood pressure, not taking medication to lower blood pressure (Canada); Self-reported of having been told by a healthcare provider that they have high blood pressure, not taking medication to lower blood pressure (USA).
Unaware: No self-report of having been diagnosed as hypertensive by a doctor or nurse (ENGLAND); no self-report of having been told that they have high-blood pressure and no self-report of BP medication use in the past month (Canada); no self-report of having been told that they have high-blood pressure (USA).
