Commentary: Sodium and blood pressure in the Intersalt study and other studies—in reply to the Salt Institute: Fig 1
Key result
Higher population salt intake is significantly associated with a greater upward slope of blood pressure with age, with 100 mmol more sodium linked to a 9 mm Hg higher systolic BP over 30 years.
Why the study?
Does higher population sodium intake increase blood pressure and the upward slope of blood pressure with age in adults?
Population
Over 10,000 adults across 52 populations from the Intersalt study
Comparison
Higher population sodium intake vs Lower population sodium intake

Cite This Study
Stamler et al. (1996) conducted a letter in Hypertension (n=10,000). Sodium intake was evaluated on Slope of blood pressure with age. Higher population salt intake is significantly associated with a greater upward slope of blood pressure with age, with 100 mmol more sodium linked to a 9 mm Hg higher systolic BP over 30 years.
