The one-fourth of women consuming the least amount of potassium—less than 1925 mg per day—were 14% more likely to die than women consuming more potassium than this after adjusting for multiple risk factors according to the 2014 Women’s Health Initiative Observational Study.

The risk of death was similar in each quarter of women consuming more potassium than this.

The second quarter of women who consumed 1925 to 2519 mg of potassium per day were 9% less likely to die during the 11 year follow-up than the one-quarter of women consuming the least potassium (less than 1925 mg per day).

The third quarter of women who consumed 2519 to 3194 mg of potassium per day were 16% less likely to die during the 11 year follow-up than the one-quarter of women consuming the least potassium (less than 1925 mg per day).

The quarter of women who consumed the most potassium—more than 3194 mg of potassium per day—were 10% less likely to die during the 11 year follow-up than the one-quarter of women consuming the least potassium (less than 1925 mg per day).

The Women’s Health Initiative Observational Study (WHI-OS), the largest prospective cohort study of postmenopausal women with long-term follow-up, was used to assess whether higher dietary potassium consumption is associated with reduced risk of total, ischemic or hemorrhagic stroke, and all-cause mortality.

Subjects

Subjects: 90,137 postmenopausal women, 50- to 79-years-old

The study followed 90,137 postmenopausal women, 50- to 79-years-old at enrollment, free of stroke history at baseline, for an average of 11 years.
