Background

Chronic kidney disease (CKD) is a common and growing problem in Korea. Although CKD awareness is the first step of CKD management, evidence indicates that the rate of CKD awareness is unsatisfactory worldwide. Thus, we investigated the trend of CKD awareness for CKD patients in Korea.

Methods

Through analyzing data of Korea National Health and Nutrition Examination Survey (KNHAES) in 1998 (phase I), 2005 (phase III), 2010-2012 (phase V), and 2016-2018 (phase VII), we evaluated the rate of CKD awareness according to CKD stage in each phase of KNHANES. CKD was defined when estimated glomerular filtration was below 59 ml/min/1.73m2. Clinical and sociodemographic characteristics were compared between CKD awareness and unawareness groups. Multivariate regression analysis was used to calculate adjusted odds ratio (OR) and 95% confidence interval (CI) for CKD awareness (adjusted OR [95% CI]) in given socioeconomic and clinical factors.

Results

The overall rate of CKD awareness remained at low levels less than 4.1% across all phases of KNHANES. In particular, the rate of CKD awareness was remarkably low in stage 3 CKD. Compared to CKD unawareness group, CKD awareness group was of young age, higher income, higher education, more medical aid, higher prevalence of comorbidities, and more advanced CKD. In multivariate analysis, CKD awareness was significantly associated with younger age (0.95 [0.93-0.98]), medical aid (4.35 [1.95-9.73]) and renal function (0.90 [0.88-0.92]).

Conclusion

The rate of CKD awareness has been consistently low in Korea. This trend warrants the special endeavor to promote CKD awareness in Korea.
