Factors Associated With Hypertension Control in US Adults Using 2017 ACC/AHA Guidelines: National Health and Nutrition Examination Survey 1999-2016.

BACKGROUND: Factors and trends associated with hypertension control (BP < 130/80 mm Hg) and mean blood pressure (BP) among hypertensive adults (BP ≥1 30/80 mm Hg or medicated for hypertension).

METHOD: Data on 22,911 hypertensive US adults from the 1999-2016 National Health and Nutrition Examination Survey.

RESULTS: For men, hypertension control prevalence increased from 8.6% in 1999-2000 to 16.2% in 2003-2004 (P < 0.001), and continued the increasing trend afterwards to 23.2% in 2011-2012 (P < 0.001) and then plateaued. For women, hypertension control prevalence increased from 1999-2000 to 2009-2010 (10.8-26.3%, P < 0.001) and then plateaued. For men with hypertension, systolic BP decreased from 1999-2000 to 2011-2012 (135.7-132.8 mm Hg, P < 0.001) and then increased to 135.3 mm Hg in 2015-2016 (P < 0.001). For women with hypertension, systolic BP decreased from 1999-2000 to 2009-2010 (139.7-131.9 mm Hg; P < 0.001) and then increased to 134.4 mm Hg in 2015-2016 (P = 0.003). Diastolic BP decreased from 1999-2000 to 2015-2016 (men: 79.1-75.5 mm Hg and women: 76.4-73.7 mm Hg, P < 0.001 for both). In 2011-2016, hypertension control was 22.0% for men and 25.2% for women. The adjusted prevalence ratio (PR) of hypertension control were lower for non-Hispanic black men and women (PR = 0.72, 95% confidence interval (CI) = 0.61-0.86; PR = 0.83, 95% CI = 0.70-0.99, respectively; non-Hispanic white (NHW) as reference), Hispanic and non-Hispanic Asian men (PR = 0.70, 95% CI = 0.54-0.92; PR = 0.59, 95% CI = 0.39-0.86; respectively; NHW as reference).

CONCLUSION: Hypertension control significantly increased from 1999-2000 to 2011-2012 (men) and 2009-2010 (women) and then plateaued. About a quarter of US adults with hypertension were controlled in 2011-2016.
