To evaluate secular trends in blood pressure distribution, hypertension prevalence, and changes in hypertension awareness, treatment, and control among US adults from 1960 through 1991.
Analyzed four nationally representative cross-sectional health examination surveys conducted between 1960-1962, 1971-1974 (NHANES I), 1976-1980 (NHANES II), and 1988-1991 (NHANES III).
Evaluated cohorts of 6,530 to 13,645 noninstitutionalized US adults aged 18 to 74 years per survey cycle via in-person interviews and standardized clinical blood pressure measurements.
Age-adjusted hypertension prevalence defined at ≥140/90 mm Hg peaked at 36.3% in NHANES I and declined to 20.4% in NHANES III, while prevalence defined at ≥160/95 mm Hg decreased from ~20% to 14.2%.
Age-adjusted mean systolic blood pressure fell from 131 mm Hg in NHANES I to 119 mm Hg in NHANES III, with reductions noted across all age-sex-race subgroups except Black men aged 50 and older.
Mean systolic pressures dropped by 3 to 6 mm Hg and diastolic pressures dropped by 6 to 9 mm Hg across all sex-race subgroups between NHANES II and NHANES III.

Structured PICO

Population

US adults aged 18 through 74 years, examined in four separate national surveys (1960-1962, 1971-1974, 1976-1980, and 1988-1991), with between 6530 and 13,645 adults per survey.

Outcome

Secular trends in the distribution of blood pressure and prevalence of hypertension, and changes in rates of awareness, treatment, and control of hypertensionsurrogate

Between 1960 and 1991, the prevalence of hypertension and mean blood pressure levels in the US adult population declined significantly.

Limitations

Protocols for blood pressure measurement varied significantly across the surveys

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports long-term US BP declines; leaves open contemporary trends, drivers, and relevance to current practice.
