Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
From the 2005-2006 and 2007-2008 National Health and Nutrition Examination Survey:
Have you ever been told by a doctor or other health professional that you had hypertension, also called high blood pressure?
Because of your high blood pressure/hypertension, have you ever been told by a doctor or other health professional to take prescribed medication?
Are you now taking prescribed medication?
Adults are defined as having high blood pressure/hypertension if they either: (a) have a measurement of mean systolic blood pressure (SBP) ≥140 mm Hg or (b) mean diastolic blood pressure (DBP) ≥90 mm Hg or (c) report that they are taking high blood pressure medicine.
Blood pressure is measured by averaging up to 3 blood pressure readings taken during the physical examination in the NHANES mobile examination center.
Blood pressure has been measured with the mercury sphygmomanometer for many years but with new technologies available, alternative blood pressure devices have taken center stage. The rapid pace of the development of automated sphygmomanometers with improving accuracy and reliability combined with increasing affordability has meant that these devices have now replaced the mercury sphygmomanometer in many settings. A detailed description of the procedures for blood pressure measurement in the NHANES has been published elsewhere.
