Epidemiological Evidence of an Interaction Between Calcium and Sodium Intake Impacting on Blood Pressure: A Montreal Study
Why the study?
Does the interaction between dietary calcium and sodium intake impact systolic and diastolic blood pressure in a general population?
Population
182 randomly selected Canadians from Montréal
Comparison
Dietary calcium and sodium intake vs Different levels of dietary calcium and sodium…

Implication
Hypothesis-generating for calcium-sodium interaction on BP; should not change dietary advice pending prospective trials.

P
Population
182 randomly selected Canadians from Montréal
I
Intervention
Dietary calcium and sodium intake
C
Comparator
Different levels of dietary calcium and sodium intake (terciles)
O
Outcome
Systolic and diastolic blood pressuresurrogate
Dietary calcium intake appears to modulate the blood pressure response to sodium, suggesting a protective effect of high calcium against sodium-induced blood pressure increases.
