No hypertension was defined as SBP <130 mmHg, DBP<80 mmHg, and no treatment with antihypertensive medication.
Newly classified with hypertension was defined as SBP≥130 mmHg or DBP≥80 mmHg and, SBP<140 mmHg and DBP<90 mmHg, and no treatment with antihypertensive medication.
Hypertension based on traditional criteria was defined as SBP≥140 mmHg, DBP≥90 mm Hg, and/or current use of an antihypertensive medication.
In this group, 39% were classified as hypertensive based on SBP only, 43% based on DBP only, and 18% based on SBP and DBP.
In this group, 13% were classified as hypertensive based on SBP only, 2% on DBP only, 4% based on SBP and DBP, and 80% based on use of antihypertensive medications.
