How common is high blood pressure in Asian people in the US?

According to the 2017 American College of Cardiology and American Heart Association hypertension guidelines, the threshold for diagnosing hypertension is now defined as ≥130/80 mm Hg.¹ The previous threshold from the 2003 JNC7 guidelines was ≥140/90.^2,3 This change raised the number of people diagnosed with hypertension significantly.¹

Muntner et al. performed an analysis of the impact of the new guidelines on the US population.⁴ They used the 2011 – 2014 National Health and Nutrition Examination Survey data (n=10,907, ≥20 years old) to determine the percentage of adults with hypertension in the US population and within different racial, ethnic, and gender subgroups comparing the 2017 versus the 2003 JNC-7 guideline thresholds for hypertension diagnosis. This analysis found that 36.7% of all US Asian adults meet the criteria for hypertension diagnosis (95% confidence interval [CI] [32.6 – 40.9]). That is 4.4 million US Asian adults with hypertension. Among US Asians, 24% (95% CI [21.1 – 28.2]) met the 2003 JNC-7 criteria for hypertension diagnosis.
