Percentage of Adults with High Blood Pressure Whose Hypertension is Adequately Controlled

Heart disease and stroke are the first and third leading causes of death. High blood pressure is a major risk factor for cardiovascular disease, particularly if it is not controlled.

Data Source: National Health and Nutrition Examination Survey (NHANES)

Metrics Calculation

Numerator: Those with blood pressure under control. Controlled high blood pressure is defined as: Systolic BP less than 140 mm Hg and diastolic BP less than 90 mm Hg (the average of up to three brachial systolic and diastolic blood pressure readings was used for systolic and diastolic BP values) among those with high blood pressure, where high blood pressure defined as systolic blood pressure of 140 mm Hg or greater, or diastolic blood pressure of 90 mm Hg or greater, or currently taking medication to lower blood pressure (based on positive responses to the following questions: “Have you ever been told by a doctor or other health professional that you had hypertension, also called high blood pressure?”; “Because of your [high blood pressure/hypertension], have you ever been told to take prescribed medicine?”; and “Are you now taking a prescribed medicine?”).

Denominator: People 18+ years with measured high blood pressure or on blood pressure medication.

 

Crude prevalence estimates (i.e., not age-adjusted) of civilian, non-institutionalized population are provided.

Additional Information

Inclusion Criteria: All non-pregnant survey participants ages 18+ years with non-zero blood pressure measurements.

Exclusion Criteria: Pregnant women.

Blood pressure measurements were not obtained in survey participants less than age 8 years and use of anti-hypertensive medication questionnaire not asked of survey participants less than age 16 years. Insufficient sample size of controlled blood pressure for ages 16-17 years, therefore this age range not included. Two years of data were pooled to create the estimates by population characteristics because of sample size limitations.

 

Due to small sample sizes for NHANES data, 95% confidence intervals are provided, which are important for interpreting the variability around the prevalence point estimates. 

For insurance estimates, the following definitions are used: Private insurance excludes plans that pay for only one type of service, such as dental or vision care. Persons covered by both Medicare and Medigap plans are classified as having public coverage. Public coverage includes Medicaid, Children’s Health Insurance Program (CHIP), state-sponsored or other government-sponsored health plan, Medicare (disability), Indian Health Service or military health care (TRICARE, VA, or CHAMP-VA).

 

This measure is calculated by the Centers for Disease Control and Prevention, National Center for Health Statistics from the National Health and Nutrition Examination Survey.
