Estimated Hypertension Prevalence, Treatment, and Control Among U.S. Adults

Hypertension, also known as high blood pressure, increases the risk for heart disease and stroke, two leading causes of death in the United States.1

Clinicians diagnose patients as having hypertension and make treatment decisions by comparing patients’ systolic and diastolic blood pressure readings to certain thresholds.

Current guidelines issued in 2017 by many organizations—including the American College of Cardiology (ACC) and American Heart Association (AHA)—define hypertension as blood pressure consistently at or above 130/80 mm Hg.2

Key Facts

The key facts shown in the Figure and Tables 1 and 2 [PDF – 475 KB] include the following estimates for the US adult population:

  • Nearly half of adults have hypertension (119.9 million).
  • About 1 in 4 adults with hypertension have their hypertension under control (27.0 million).
  • All adults with hypertension are recommended by a clinician to undergo lifestyle modifications. This is the only treatment recommendation for 1 in 5 adults (25.0 million).
  • Most adults with hypertension (4 in 5) are also recommended by a clinician to take prescription medication(s) (94.9 million).
  • Many adults who are already treated with antihypertensive medication(s) may need to have their current medication dosage increased or to be prescribed additional medications to achieve blood pressure control (33.2 million). More than half of this group have blood pressure ≥140/90 mm Hg (18.8 million).
  • Many adults for whom hypertension medication is recommended by a clinician are untreated (34.8 million). Two-thirds of this group have blood pressure of ≥140/90 mm Hg (23.4 million).

Application of the ACC/AHA 2017 Guidelines

The following figure highlights the number of US adults aged 18 and older who have hypertension. This figure applies criteria from the 2017 ACC/AHA guideline to data from the 2017 to 2020 National Health and Nutrition Examination Survey (NHANES).

The figure also shows the number of:

  • People with hypertension who are recommended to use either lifestyle modifications only or lifestyle modifications with prescription medication to manage their blood pressure.
  • People with hypertension who do not have their blood pressure controlled to <130/80 mm Hg.
  • People with hypertension who do have their blood pressure controlled to <130/80 mm Hg.

Estimated hypertension prevalence, treatment, and control among U.S. adults. Heading ends. (Blood pressure control is defined as less than 130 over 80 millimeters of mercury.) Footnote: Among adults aged 18 years and older; estimates may not equal 100% due to rounding. Footnote ends. 48.1% of adults in the U.S. (119.9 million people) have hypertension (blood pressure 130 over 80 or higher or currently using prescription to lower blood pressure). For 20.9% of U.S. adults (25 million people), the recommended intervention is lifestyle modifications only. For 79.1% (94.9 million people), the recommended intervention is lifestyle modifications plus medication. For 77.5% of U.S. adults (92.9 million people), their blood pressure is uncontrolled. For 22.5% (27 million people), their blood pressure is controlled. Controlled is defined as having a blood pressure lower than 130 over 80 millimeters of mercury. All adults recommended lifestyle modifications only are considered uncontrolled as their blood pressure is above the threshold.
