The Prevalence of Chronic Kidney Disease (CKD) and the Associated Factors to CKD in Urban Korea: A Population-based Cross-sectional Epidemiologic Study

다국어 초록 (Multilingual Abstract)

Chronic kidney disease (CKD) is a worldwide problem. This study was designed to

survey the prevalence and risk factors for CKD in Korea. The 2,356 subjects were

selected in proportion to age, gender, and city. Subjects 35 yr of age or older were

selected from 7 cities. Estimated glomerular filtration rate (eGFR) was calculated

using the Modification of Diet in Renal Disease (MDRD) Study equation, with albuminuria

defined as a urine albumin to creatinine ratio of 30 ㎎/g or more. The

overall prevalence of CKD was 13.7%. The prevalences of CKD according to stage

were 2.0% stage 1, 6.7% stage 2, 4.8% stage 3, 0.2% stage 4, and 0.0% stage 5.

The prevalences of microalbuminuria and macroalbuminuria were 8.6% and 1.6%,

respectively. The prevalence of eGFR less than 60 mL/min/1.73 ㎡ was 5.0%. Age,

body mass index (BMI), hypertension, diabetes mellitus, systolic blood pressure

(SBP), diastolic blood pressure (DBP), and fasting blood glucose were independent

factors related to the presence of CKD. In conclusions, Korea, in which the prevalence

of CKD is increasing, should prepare a policy for early detection and appropriate

treatment of CKD. The present data will be helpful in taking those actions.
