Normal range of serum potassium, prevalence of dyskalaemia and associated factors in Chinese older adults: a cross-sectional study.

ABSTRACT:

Objective

To investigate the normal range of serum potassium, the prevalence of dyskalaemia and the associated factors in Chinese older adults.

Design

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

Setting

Forty-eight community elderly care facilities in four regions in northern China.

Participants

A total of 1266 (308 apparently healthy and 958 unhealthy) participants 55 years or older and with fasting serum potassium measured.

Main outcome measures and methods

Serum potassium <3.5 mEq/L and >5.5 mEq/L (guidelines definition) and <2.5th and >97.5th percentiles of the distribution among healthy participants (our study definition) were both used to define hypokalaemia and hyperkalaemia, respectively. Multivariable generalised estimat
