Prevalence of chronic kidney disease and associated factors in Chinese individuals with type 2 diabetes: Cross-sectional study

Abstract

AimsThis cross-sectional study aimed to determine the prevalence and associated risk factors of chronic kidney disease (CKD) in Chinese type 2 diabetic patients. MethodsA total of 3301 patients with type 2 diabetes were included in this study. Anthropometric parameters and biochemical indices were measured. The main outcome measures were detection of CKD, albuminuria and estimated glomerular filtration rate (eGFR). ResultsThe prevalence of CKD and albuminuria in Shanghai Chinese type 2 diabetic patients was 27.1% and 25.2%. The prevalence of mildly decreased renal function or worse (eGFR<60/mL/min/1.73m2) was 6%. The prevalence of glomerular hyperfiltration was 12.2%. The prevalence of diabetic kidney disease (DKD) according to the newest NKF’s KDOQI classification was 12.03%. Risk factors associated with DKD were SBP, retinopathy, neuropathy, TG, LDL, anemia and HbA1c. Clinical factors associated with both albuminuria and low eGFR (≥60/<60) were SBP, retinopathy, TC, TG and anemia. ConclusionIn conclusion, CKD and DKD were common in the Shanghai Chinese patients with T2DM and were similar to that in Western patients. Prevention and control of diabetes should be a high priority in reducing the CKD burden in China.
