Booth JN, et al. - Using 2011-2014 National Health and Nutrition Examination Survey (n=9,623), researchers determined the percentage of US adults who fulfill the criteria for out-of-clinic BP monitoring by American College of Cardiology/American Heart Association guidelines. Among US adults not taking antihypertensive medication, 92.6% with systolic/diastolic BP ≥ 130/80 mmHg met criteria for out-of-clinic BP monitoring to screen for white coat hypertension, and 32.8% with systolic/diastolic BP<130/80 mm Hg met criteria to screen for masked hypertension. Among US adults taking antihypertensive medication, 12.5% with systolic/diastolic BP ≥ 130/80 mmHg met criteria to screen for white coat effect, and 57.4% with systolic/diastolic BP < 130/80 mmHg met criteria to screen for masked uncontrolled hypertension. Criteria for out-of-clinic BP monitoring to screen for white coat effect was more commonly met at an older age and among non-Hispanic black individuals than non-Hispanic white individuals and to screen for masked uncontrolled hypertension in older adults and men. Overall, the 2017 Hypertension Clinical Practice Guidelines criteria for out-of-clinic BP monitoring were met by approximately 103.8 million US adults (45.8%).
