Impact of the Number of Blood Pressure Measurements on Blood Pressure Classification in U.S. Adults: NHANES 1999–2008

BackgroundClinical guidelines recommend averaging ≥2 blood pressure (BP) measurements on each visit. Only one BP is measured on many clinical visits, especially if the value is <120/<80 mmHg, i.e., normal. The impact of this practice on accurate assignment of BP category is incompletely defined.
