The available data appear to show that the increased cardiovascular risk among those with
sodium excretion greater than 3.0 grams per day is explained entirely by the variables of BMI, sex and hypertension.
Not exact matches
But approximately 90 percent of the participants in the PURE study had either a high (
greater than 5.99 grams per day) or moderate (3 to 5.99 grams per day) level of
sodium excretion; approximately 10 percent excreted less than 3 grams per day, and only 4 percent had
sodium excretion in the range associated with current U.S. guidelines for
sodium intake (2.3 or 1.5 grams per day).
Findings: mean
sodium excretion was 4.93 g. Compared to a reference range of 4.00 - 5.99 g a day, the odds ratio for death and cardiovascular events was 1.15 for high
sodium excretion (over 7 g a day) but was even
greater at 1.27 for a low
sodium excretion (below 3 g).
Excess
sodium excretion of
greater than 7,000 milligrams and a deficiency of less than 3,000 milligrams per day were both associated with a higher risk of stroke, heart attack, and death.
