Background: Potassium is a critical mineral to mitigate the negative effects of excessive sodium intake by reducing blood pressure and thus preventing stroke. Potassium is also required for metabolism and normal heart, muscle, and nerve functions. The purpose of this study was to examine the effect of potassium intake on the quality of life among elderly.

Subjects and Method: A cross sectional study was conducted at Karanganyar health center, Central Java, from May to June 2019. A sample of 165 elderly was selected for this study randomly. The dependent variable was quality of life. The independent variable was potassium intake. Potassium intake was measured by 24 hours recall questionnaire. Quality of life was measured by WHOQOL-BREF questionnaire. The data were analyzed by Spearman rank.

Results: Potassium intake showed weak positive correlation with quality of life in the elderly, and it was statistically significant (r= 0.18; p= 0.018).

Conclusion: Potassium intake is associated with improved quality of life in the elderly.
