Abstract
BackgroundThe aim of the present study was to investigate the clinical impact of prediabetes on the development of incident chronic kidney disease (CKD) in a Korean adult population, using data from the Korea Genome and Epidemiology Study.MethodsThis prospective cohort study included 7728 Korean adults without baseline CKD and type 2 diabetes. Prediabetes was defined by impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and HbA1C level. CKD was defined as estimated glomerular filtration rate < 60 mL/min/1.73 m2. We assessed the predictive value of prediabetes for the incidence of CKD, and investigated the incidence of cardiovascular disease including coronary artery disease and stroke.ResultsOver a median follow-up period of 8.7 years, 871 of 7728 (11.3%) subjects developed incident CKD. Patients with prediabetes, as defined by IGT or HbA1C, developed incident CKD more frequently than the non-prediabetic group did. The risk of CKD development at follow-up was analyzed according to different prediabetes definitions. Compared with the non-prediabetic group, the IGT- (Hazard ratio [HR] = 1.135, 95% confidence interval [CI] = 1.182–1.310, P = 0.043) and HbA1C-defined prediabetic groups (HR = 1.391, 95% CI = 1.213–1.595, P < 0.001) were significantly associated with incident CKD after adjusting for traditional CKD risk factors; however, IFG was not associated with incident CKD.ConclusionIGT- or HbA1C-defined prediabetes is an independent predictor of incident CKD. The measurement of these parameters might enable early detection of CKD risk, allowing physicians to initiate preventive measures and improve patient outcomes.

Prediabetes can be defined according to impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or HbA1C level, and a previous study suggested that each of these components might have a different association with CKD [7]
Prediabetes defined according to IGT or HbA1C level was more frequently noted in the CKD group, but
Summary
The aim of the present study was to investigate the clinical impact of prediabetes on the development of incident chronic kidney disease (CKD) in a Korean adult population, using data from the Korea Genome and Epidemiology Study. It is important to identify modifiable risk factors that can act as early predictors of incident CKD. Prediabetes, which is regarded as a CVD risk factor, is an intermediate state of hyperglycemia, wherein blood glucose is higher than normal but lower than that in diabetes [5, 6]. Prediabetes can be defined according to impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or HbA1C level, and a previous study suggested that each of these components might have a different association with CKD [7]
