Association of serum potassium level with dietary potassium intake in Chinese older adults: a multicentre, cross-sectional survey.

ABSTRACT:

Objectives

Evidence linking dietary potassium and serum potassium is virtually scarce and inconclusive. The aim of the study was to investigate the association between serum potassium level and potassium intake measured by 24-hour urine. We also explored whether the association differed across health conditions.

Design

A cross-sectional study conducted from September 2017 to March 2018.

Setting

48 residential elderly care facilities in northern China.

Participants

Participants aged 55 years and older and with both serum potassium and 24-hour urinary potassium measured were classified as having a low (apparently healthy), moderate (with ≥1 health condition but normal renal function) and high (with ≥1 health condition and abnormal renal function) risk of hyperkal
