Prevalence, Incidence and Mortality of Chronic Kidney Disease in Type 1 and Type 2 Diabetes—A Nationwide Danish Register‐Based Cohort Study
Authors' conclusion
From 2016 to 2024, CKD incidence declined while prevalence increased among people with diabetes in Denmark. Mortality remained high among people with CKD

Main finding
As reported in the abstract
CKD prevalence and incidence, 2016 to 2024
Chronic kidney disease (CKD) prevalence in T1D, 2016 to 2024
20.5% to 26.4%
CKD prevalence in T2D, 2016 to 2024
24.8% to 37.3%
CKD incidence in T1D, 2016 to 2024
21.5 to 14.9 per 1000 PY
CKD incidence in T2D, 2016 to 2024
55.3 to 43.7 per 1000 PY
Observational data: associations, not effects.
Further findings
CKD incidence, T2D aged ≥ 70 years · 2016 to 2024
- Largest reduction in older people (aged ≥ 70 years with T2D)
- 93.6 to 74.3 per 1000 person-years (PY)
Albuminuria
- Albuminuria prevalence increased, whereas incidence declined in both diabetes types
Mortality
- Mortality declined in people with and without CKD but remained substantially higher among those with CKD
