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

ABSTRACT

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.
