To investigate the relationship between 24-hour urinary sodium, urinary potassium, sodium-potassium ratio and microalbuminuria among people in elderly care institutions.
Questionnaire survey, physical examination, blood and 24 h urine samples collection were carried out in the elderly people of 16 elderly care institutions in southeastern Shanxi from September 2017 to November 2017, which were selected using the random cluster sampling method. A multivariate logistic regression model was used to analyze the association between 24 h urinary sodium excretion, urinary potassium excretion, sodium-potassium ratio and MAU.
A total of 502 subjects including 467 males (93.03%) and 33 MAU (6.57%) were included in this study (average age: 65.77±8.54 years old). The 24 h urinary sodium excretion was (193.02±87.64) mmol, urinary potassium excretion was (27.95±15.02) mmol, and the sodium-potassium ratio was (7.44±2.62), respectively. Multivariate logistic regression analysis showed that group with the highest urinary sodium excretion and the sodium-potassium ratio (Q4) compared to the lowest group (Q1) was associated with an increased risk of MAU (OR=4.026, 95% CI: 1.045-15.515; OR=4.043, 95% CI: 1.252-13.057).
The 24-hour urinary sodium and sodium-potassium ratio are positively associated with the prevalence of MAU, while 24-hour urinary potassium is not related to the prevalence of MAU.
