The global, regional, and national patterns of change in the burden of chronic kidney disease from 1990 to 2021

Chronic kidney disease (CKD) is a major global public health problem with increasing prevalence and a huge health and economic burden. Diabetes mellitus and hypertension are major risk factors for CKD, and CKD is associated with cardiovascular disease and end-stage renal disease. Understanding the prevalence and burden of CKD is essential for the development of prevention and control strategies.

Using data from the Global Burden of Disease Study (GBD) 2021 study, this study analyzed the incidence, prevalence, and disability-adjusted life years (DALYs) of CKD at global, regional, and national levels between 1990 and 2021. Decomposition analysis, health inequalities and frontier analysis were used to analyse the changes.
