Increased risk of new-onset type 2 diabetes in people with chronic kidney disease

Purpose: This study investigated whether people with chronic kidney disease (CKD) are at the risk of new-onset type 2 diabetes. Methods: A cohort comprising 16,624 people with CKD, and an age- and sex-matched control cohort of 66,496 persons without any clinical kidney disease were identified from the Taiwan National Health Insurance Database during the period of 2000–2010. Both cohorts were followed up to 2011 to evaluate the incidence and hazard ratio (HR) of developing new-onset type 2 diabetes. Diseases were identified based on diagnosis coding. Results: The incidence of type 2 diabetes was 1.51-fold higher in the CKD cohort than in the control cohort (16.9 versus 11.2 per 1,000 person-years) with an adjusted hazard ratio of 1.17 (95% confidence interval, (CI)1.10–1.24). In the multivariate Cox regression model considering the competing-risk death, the adjusted subhazard ratio of type 2 diabetes was 1.30 (95% CI1.22–1.38) for the CKD cohort compared to the control cohort. Conclusions: People with CKD patients are at an increased risk of developing new-onset type 2 diabetes. Close surveillance for diabetes should be considered for these people.
