The prevalence of CKD in adults ≥18 years of age with type 1 diabetes in the U.S. was determined using National Health and Nutrition Examination Survey (NHANES) data.


A modified treatment-based algorithm applying a subset of NHANES diabetes questionnaires was used. The number of respondents with CKD and type 1 diabetes was weighted (extrapolated) to the U.S. population.


Based on data between 2015 and 2018, type 1 diabetes was identified in 47 out of 19,225 adults with evaluable kidney function data. CKD was present in 20 out of 47 people identified with type 1 diabetes. The weighted estimate of CKD in type 1 diabetes was 21.5%, corresponding to 258,196 (95% CI 71,189–445,203) people in the U.S.


Applying a conservative approach in our study indicates that CKD is common in adults with type 1 diabetes in the U.S.
