In ARIC, prevalent hypertension included use of antihypertensive medication or measured blood pressure (systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg); prevalent diabetes was defined as fasting glucose levels ≥ 126 mg/dl, nonfasting glucose levels ≥ 200 mg/dl, or self-reported diagnosis of diabetes or use of diabetic medication. In CHS, prevalent hypertension included measured blood pressure (systolic blood pressure ≥140% mmHg, diastolic blood pressure ≥90 mmHg) or use of antihypertensive drug and reports of physician diagnosis of hypertension; prevalent diabetes was defined as fasting glucose levels ≥ 126 mg/dl, or use of insulin or an oral hypoglycemic drug.
