High Blood Pressure Affects Almost a Third of U.S. Adults

A new report from NCHS shows that hypertension affects almost one-third of the U.S. adult population. In 2009–2010, nearly 82% of adults with hypertension were aware of their status, and nearly 76% were taking medication. Despite considerable improvement in increasing the awareness, treatment, and control of hypertension, undiagnosed and uncontrolled hypertension among minority groups remains a challenge. This report presents survey results for 2011–2012 on the prevalence, awareness, treatment, and control of hypertension.

Age-specific and age-adjusted prevalence of hypertension among adults aged 18 and over: United States, 2011–2012

Key Findings From the Report:

  • The age-adjusted prevalence of hypertension among U.S. adults aged 18 and over was 29.1% in 2011–2012, similar to the prevalence in 2009–2010.
  • The prevalence of hypertension was similar for men and women at nearly one-third. The prevalence increased with age and was highest among older adults; it was also highest among non-Hispanic black adults, at approximately 42%.
  • Among adults with hypertension, nearly 83% were aware, nearly 76% were taking medication to lower their blood pressure, and nearly 52% were controlled. There was no change in awareness, treatment, and control from 2009–2010 to 2011–2012.
  • Controlled hypertension was similar across race and Hispanic origin groups, but the percentage controlled was higher for women and older adults.
