Key result
Community health education fails to reduce cardiovascular risk factors compared to control cities.
Why the study?
Trends in blood pressure, smoking, and cholesterol by educational level over time were examined to understand cardiovascular risk factor changes across education groups.
Does a community health education intervention improve cardiovascular risk factors across different educational levels compared to control cities?
Population
6,580 men and women ages 25-74 from four California cities stratified by educational level
Comparison
Treatment cities with community health education intervention vs control cities without intervention
Design
Four biennial cross-sectional surveys as part of the Stanford Five-City Project
Follow-up
8-year study period

Community-wide CV risk factor declines occurred independently of education programs; leaves open whether such interventions confer benefit beyond secular trends.
Cross-Sectional (n=6,580)

Does a community health education intervention improve cardiovascular risk factors across different educational levels compared to control cities?
Broad-based health education efforts appear to successfully reduce cardiovascular risk factors across all educational levels, particularly benefiting those with less education.
Winkleby et al. (1992) conducted a cross-sectional in Cardiovascular disease risk factors (n=6,580). Community health education intervention vs. Control cities was evaluated on Trends in blood pressure, smoking, and cholesterol. A 6-year community health education intervention showed significant declines in smoking, blood pressure, and cholesterol across all educational levels, with similar declines in control cities.
