About the National Data

Data

Data Source:  National Health and Nutrition Examination Survey (NHANES), CDC/NCHS

Baseline: 45.0 percent of adults aged 18 years and over had hypertension in 2017-20

Target: 41.9 percent

Numerator
Number of adults aged 18 years and over with hypertension, excluding pregnant women.
Denominator
Number of adults aged 18 years and over, excluding pregnant women.
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.

Target-setting method justification
The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because hypertension prevalence has had little change over the past several National Health and Nutrition Examination Survey (NHANES) cycles, and the Healthy People 2030 Workgroup Subject Matter Experts expected minimal improvement in the next decade.

Methodology

Methodology notes

Adults are defined as having high blood pressure/hypertension if they either: (a) have a measurement of mean systolic blood pressure (SBP) ≥130 mm Hg or (b) mean diastolic blood pressure (DBP) ≥80 mm Hg or (c) report that they are taking high blood pressure medicine.

Blood pressure is measured by averaging up to 3 blood pressure readings taken during the physical examination in the NHANES mobile examination center.

Blood pressure has been measured with the mercury sphygmomanometer for many years but with new technologies available, alternative blood pressure devices have taken center stage. The rapid pace of the development of automated sphygmomanometers with improving accuracy and reliability combined with increasing affordability has meant that these devices have now replaced the mercury sphygmomanometer in many settings. A detailed description of the procedures for blood pressure measurement in the NHANES has been published elsewhere.

History

Comparable HP2020 objective
Modified, which includes core objectives that are continuing from HP2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective HDS-5.1, which defined hypertension based on the Joint National Committee 7 guidelines as a systolic blood pressure of 140 mm Hg or higher or a diastolic blood pressure of 90 mm Hg or higher. This objectives uses the 2017 American College of Cardiology and American Heart Association guidelines to define hypertension as a systolic blood pressure of 130 mm Hg or higher or a diastolic blood pressure of 80 mm Hg or higher.
Revision History
  • Revised. 

    In 2022, the baseline was revised from 29.5% in 2013-2016 to 45.7% in 2017-2020 for consistency with the new 2017 guidelines on high blood pressure in adults released by the American College of Cardiology and American Heart Association released. As part of the new guidelines, the categorization of high blood pressure was changed from the previous definition recommended in the Joint National Committee 7 report. The categorization of high blood pressure was modified from a systolic blood pressure of ≥140 mm Hg to ≥130 mm Hg or a diastolic blood pressure of ≥90 mm Hg to ≥80 mm Hg. The target was revised from 27.7% to 42.6% using the original target setting method.
  • Revised. 

    In 2023, the baseline was revised from 45.7% to 45.0% due to a change in exclusion criteria for this objective. The mean systolic and mean diastolic blood pressures must not be missing. The target was revised from 42.6% to 41.9% using the original target setting method.
