Key result

Hypertension prevalence (≥140/90 mm Hg) was higher in blacks than whites (38% vs 29%); changing the threshold from 160/95 to 140/90 mm Hg lowered the apparent control rate from 34% to 11%.

Population

Implication

Stricter thresholds lower apparent control rates and widen disparities; leaves open optimal definitions for equitable surveillance.

Key Points

To estimate the prevalence of hypertension in the United States and assess awareness, treatment, and control distributions.
Utilized National Health and Nutrition Examination Survey (NHANES II) data from 1976-1980.
Defined hypertension as blood pressure ≥140/90 mm Hg or self-reported use of antihypertensive medications.
Applied prevalence rates to 1983 population data to estimate hypertension distribution by age, sex, and race.
Prevalence among blacks was 38%, compared to 29% among whites; men showed 33% prevalence versus 27% for women.
Awareness of hypertension dropped from 74% to 54% with a lowered threshold of 140/90 mm Hg.
The percentage of controlled hypertension decreased from 34% to 11% with the new threshold.

Population

United States population based on NHANES II (1976-1980) data and 1983 Bureau of the Census figures, excluding children under 6 years and persons controlling blood pressure without medication.

Outcome

Prevalence of hypertension (defined as BP ≥140/90 mm Hg or taking antihypertensive medication) and status of awareness, treatment, and control.

This consensus report established the prevalence of hypertension in the US using the ≥140/90 mm Hg threshold, highlighting significant racial and sex disparities and demonstrating that the stricter threshold substantially lowered rates of awareness, treatment, and control.

Limitations

NHANES II did not include persons 75 years of age or older in its sample
Estimates for children under 6 years of age and hypertensive persons controlling their pressures without medication could not be included
Estimates for children under 6 years of age could not be included due to lack of reliable data
Hypertensive persons controlling their pressures without medication could not be included due to lack of reliable data
