survey, the National Health and Nutrition Examination Survey (NHANES), includes direct measurement of BP on a nationally representative survey. In the United States, no national estimates of hypertension prevalence currently use 24-hour ABPM. Preventive Services Task Force recommends using 24-hour ABPM as part of hypertension screening and diagnosis ( 5). To confirm a diagnosis of hypertension, the U.S. Furthermore, clinic-based BP values offer no information about BP patterns outside of the clinical setting, such as whether a person lacks the normal pattern of “BP dipping” with sleep or has nocturnal hypertension, both potentially important risk factors for cardiovascular disease ( 4). Although measuring BP in an office setting is now the principal way of diagnosing and managing hypertension, this method may substantially over- or underestimate a person’s BP, as demonstrated by white-coat hypertension (overestimate) and masked hypertension (underestimate) ( 3). The accurate diagnosis and management of hypertension, or high blood pressure (BP), is critical to reducing the burden of cardiovascular disease morbidity and mortality ( 1– 2).
