Background-Clear and consistent definitions of hypertension and hypertension control are crucial to guide diagnosis, treatment, and surveillance. A variety of surveillance definitions are in frequent use, resulting in variation of reported hypertension prevalence and control, even when based on the same data set. Methods and Results-To assess the variety of published surveillance definitions and rates, we performed a literature search for studies and reports that used National Health and Nutrition Examination Surveys (NHANES) data from at least as recent as the 2003 to 2004 survey cycle. We identified 19 studies that used various criteria for defining hypertension and hypertension control, as well as different parameters for age adjustment and inclusion of subpopulations. This resulted in variation of reported age-standardized hypertension prevalence from 28.9% to 32.1% and hypertension control from 35.1% to 64%. We then assessed the effects of varying the definitions of hypertension and hypertension control, parameters for age adjustment, and inclusion of subpopulations on NHANES data from both 2007 to 2008 (n=5645) and 2005 to 2008 (n=10 365). We propose standard surveillance definitions and age-adjustment parameters for hypertension and hypertension control. By using our recommended approach with NHANES 2007 to 2008 data, the age-standardized prevalence of hypertension in the United States was 29.8% (SE, 0.62%) and the rate of hypertension control was 45.8% (SE, 4.03%). Conclusions-Surveillance definitions of hypertension and hypertension control vary in the literature. We present standard definitions of hypertension prevalence and control among adults and standard parameters for age-adjustment and population composition that will enable meaningful population comparisons and monitoring of trends.
