Dietary Potassium and Stroke-Associated Mortality
Abstract
Hypertension is the most important known risk factor for stroke. Clinical, experimental, and epidemiologic evidence suggests that a high dietary intake of potassium is associated with lower blood pressure. In hypertensive rats, a high intake of potassium is reported to protect against stroke, even though blood pressure is not affected. We examined the relation between the 24-hour dietary potassium intake at base line and subsequent stroke-associated mortality in a population-based cohort of 859 men and women (aged 50 to 79 years) in Southern California. After 12 years, 24 stroke-associated deaths had occurred. The relative risks of stroke-associated mortality in the lowest tertile of potassium intake, as compared with that in the top two tertiles combined, were 2.6 (P = 0.16) in men and 4.8 (P = 0.01) in women. In multivariate analyses, a 10-mmol increase in daily potassium intake was associated with a 40 percent reduction in the risk of stroke-associated mortality (P less than 0.001). This effect was independent of other dietary variables, including the intake of calories, fat, protein, fiber, calcium, magnesium, and alcohol. The effect was also apparently independent of known cardiovascular risk factors, including age, sex, blood pressure, blood cholesterol level, obesity, fasting blood glucose level, and cigarette smoking. These findings support the hypothesis that a high intake of potassium from food sources may protect against stroke-associated death.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
