Abstract: BACKGROUND: Diabetes is a significant risk factor for chronic kidney disease, and diabetic kidney disease (DKD) is prevalent among patients with diabetes. Previous studies have indicated that the duration of diabetes and poor glycemic control are associated with an increased risk of DKD, but data on how the duration and severity of hyperglycemia specifically relate to DKD progression are limited. AIM: To investigate the relationship between diabetes duration and glycemic control, and DKD progression in South Korea. METHODS: , urinary albumin-to-creatinine ratio ≥ 30 mg/g, or both. Diabetes duration and severity were classified into six categories each. RESULTS: DKD prevalence was 25.5%. The DKD risk significantly increased in diabetes lasting 10-15 years or hemoglobin A1C (HbA1c) ≥ 8% compared to patients with newly diagnosed diabetes or HbA1c < 6.5%. Albuminuria developed with shorter diabetes duration and lower HbA1c than eGFR decline. The adjusted odds ratios for DKD were 3.77 [95% confidence interval (95%CI): 2.60-5.45] and 4.91 (95%CI: 2.80-8.63) in patients with diabetes lasting ≥ 20 years and HbA1c ≥ 10%, respectively, compared to those with new-onset diabetes and HgA1c < 6.5%. CONCLUSION: Patients with diabetes lasting > 10 years or HbA1c > 8% had a higher risk of DKD, emphasizing the importance of early monitoring and management is crucial to prevent DKD progression.
