This study, conducted by the Diabetic Kidney Disease Research Group of the Korean Diabetes Association, investigates the prevalence, incidence, comorbidities, and management status of diabetic kidney disease (DKD) and diabetes-related end-stage kidney disease (ESKD) in South Korea. Using data from the Korea National Health and Nutrition Examination Survey (KNHANES) and the Korean National Health Insurance Service (NHIS), the study found that the prevalence of DKD among patients with diabetes aged 30 years and older was 25.4%, with 22.0% having albuminuria and 6.7% having a low estimated glomerular filtration rate (eGFR). The prevalence of DKD increased with age, particularly in older adults (≥70 years). Patients with DKD had higher rates of comorbidities such as hypertension, dyslipidemia, and central obesity, but lower control rates for glycemic and blood pressure management. The prescription rate of sodium glucose cotransporter 2 (SGLT2) inhibitors increased steadily, reaching 5.94% in 2019, while the prescription rate of renin-angiotensin system (RAS) blockers was around 70%. The prevalence of diabetes-related ESKD has been steadily increasing, especially in older adults, with a 19.1% increase over 11 years. Decreased kidney function was a significant risk factor for atherosclerotic cardiovascular disease (ASCVD) and mortality, with the risk of MI and stroke increasing linearly with DKD stage. The study highlights the need for intensive management of diabetes and comorbidities to prevent advanced stages of chronic kidney disease (CKD) and ASCVD.This study, conducted by the Diabetic Kidney Disease Research Group of the Korean Diabetes Association, investigates the prevalence, incidence, comorbidities, and management status of diabetic kidney disease (DKD) and diabetes-related end-stage kidney disease (ESKD) in South Korea.
