Background: Diagnosed diabetes has been associated with chronic kidney disease (CKD). However, the association between non-diabetic hyperglycemia and CKD remained uncertain. The aim of the present study was to investigate the association between different glycemic status and CKD in Chinese adults and to assess the prevalence and control of diabetes among individuals with CKD. Methods: In all, 250 752 adults aged ≥40 years were selected from the baseline cohort of the Risk Evaluation of cAncers in Chinese diabeTic Individuals: a lONgitudinal (REACTION) study. Plasma glucose concentrations and biochemical and other clinical data were collected; CKD was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min per 1.73 m2. Results: The prevalence of CKD increased gradually with deterioration of glucose metabolic status in both men and women (P trend < 0.001 for both). Compared with individuals with normal glucose regulation, men with prediabetes and diabetes had higher risks of prevalent CKD (prediabetes odds ratio [OR] 1.15, 95% confidence interval [CI] 1.02–1.32; newly diagnosed diabetes OR 1.27, 95% CI 1.08–1.49; previously diagnosed diabetes OR 2.05, 95% CI 1.78–2.35). Similar results were observed in women, but not among those with prediabetes. In male CKD patients with diabetes, 52.1% received antidiabetic treatment and 41.8% of those treated had effective glycemic control, higher than values for females. Conclusions: Prediabetes and diabetes were associated with an increased risk of CKD in Chinese men. Control of diabetes among Chinese CKD patients is far from optimal.
