Self-Reported Coffee Consumption and Central and Peripheral Blood Pressure in the Cohort of the Brisighella Heart Study
Key result
Drinking >3 cups of coffee daily is linked to ~10 mmHg lower SBP versus non-drinkers.
- MD -5.2 mmHg (2 cups/day) and -9.7 mmHg (>3 cups/day)
- P=0.010
- n=1,503
Why the study?
Although coffee consumption is linked to cardiovascular benefits, its effect on blood pressure has not been fully elucidated.
Does regular coffee consumption reduce central and peripheral blood pressure in a general population cohort?
Population
720 men and 783 women from the Brisighella Heart Study
Comparison
Different amounts of daily coffee drinking vs non-coffee drinking
Design
Cohort sub-analysis

Implication
Observational coffee-SBP link does not warrant practice change; leaves open confirmation of central/peripheral BP effects in RCTs.

Cohort (n=1,503)
Structured PICO
Does regular coffee consumption reduce central and peripheral blood pressure in a general population cohort?
P
Population
1,503 participants (52.1% women) from the Brisighella Heart Study cohort with available clinical, laboratory, and hemodynamic parameters.
E
Exposure
Self-reported coffee consumption (various amounts, including 2 cups/day and >3 cups/day)
C
Comparator
Non-coffee drinkers
O
Outcome
Central and peripheral blood pressure values (systolic blood pressure, pulse pressure, aortic blood pressure, and aortic pulse pressure)surrogate
Main Result
Mean Difference: -5.2
p-value: p=0.010
Regular coffee consumption is associated with lower central and peripheral blood pressure without affecting arterial stiffness.

Cicero et al. (2023) reported a cohort. Coffee consumption vs. Non-coffee drinkers was evaluated on Systolic blood pressure (SBP) (MD -5.2 mmHg (2 cups/day) and -9.7 mmHg (>3 cups/day), p=0.010). Drinking 2 or >3 cups of coffee per day was associated with lower systolic blood pressure compared to non-coffee drinkers (by 5.2 mmHg, p=0.010 and 9.7 mmHg, p=0.007, respectively).
