Association Between Income Disparities and Risk of Chronic Kidney Disease: A Nationwide Cohort Study of Seven Million Adults in Korea.

ABSTRACT:

Objective

To examine the association between income level and incident chronic kidney disease (CKD) in adults with normal baseline kidney function.

Patient and methods

We studied the association between income level categorized into deciles and incident CKD in a national cohort comprised of 7,405,715 adults who underwent National Health Insurance Service health examinations during January 1, 2009, to December 31, 2015, with baseline estimated glomerular filtration rates (eGFRs) ≥60 mL/min/1.73 m². Incident CKD was defined as de novo development of eGFR <60 mL/min/1.73 m² (model 1) or ≥25% decline in eGFR from baseline values accompanied by eGFR <60 mL/min/1.73 m² (model 2).

Results

During a median follow-up of 4.8 years, there were 122
