* Hypertension was defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg or currently taking medication to lower blood pressure, based on positive responses to the following questions: "Because of your high blood pressure/hypertension have you ever been told to take prescribed medicine?" and "Are you now taking a prescribed medicine?" Undiagnosed hypertension was a finding of hypertension and a negative response to the following question: "Have you ever been told by a doctor or other health professional that you had hypertension, also called high blood pressure?"

† Health insurance coverage is at the time of interview. Public coverage includes Medicaid, Children's Health Insurance Program (CHIP) state-sponsored or other government-sponsored health plan, Medicare (disability), or military health plan (TRICARE, VA, or CHAMP-VA). Persons with both public and private insurance coverage were included in the private coverage category only.
