Alcohol consumption and blood pressure: a comparison of native Japanese to American men
Key result
Alcohol consumption is linked to higher systolic and diastolic BP in Japanese and American men.
- P<0.001
- n=1,756
Why the study?
The independent association between alcohol consumption and blood pressure and its variation between Japanese and American men was unclear.
Is alcohol consumption associated with higher blood pressure in Japanese and American men?
Population
810 Japanese men in Tokyo and 946 white men in New York
Comparison
Alcohol consumption vs abstainers
Design
Cross-sectional study

Implication
Supports alcohol moderation for BP control in men; leaves open causality and generalizability from cross-sectional data.

Structured PICO
Is alcohol consumption associated with higher blood pressure in Japanese and American men?
P
Population
1,756 men (810 Japanese men in Tokyo and 946 white men in New York) evaluated for the cross-sectional association between alcohol consumption and blood pressure.
E
Exposure
Alcohol consumption
C
Comparator
Abstainers (no alcohol consumption)

Main Result
p-value: p=<0.001
Alcohol consumption is independently associated with higher blood pressure in both Japanese and white American men, despite potential differences in alcohol metabolism.
Limitations
- Potential under-reporting of heavy alcohol ingestion by American abstainers

Klag et al. (1990) conducted a cross-sectional in Hypertension (n=1,756). Alcohol consumption vs. Abstainers was evaluated on Systolic and diastolic blood pressure (p=<0.001). Alcohol consumption was independently associated with higher systolic and diastolic blood pressure in both Japanese and American men (p<0.001 for systolic BP in both groups).
