Global CKD Burden Doubled Since 1990 With Diabetes and Hypertension Leading
GBD 2023 analysis reveals chronic kidney disease affects hundreds of millions globally, with modifiable risk factors driving accelerating rates.
Summary
The Global Burden of Disease 2023 study provides the most comprehensive analysis to date of chronic kidney disease (CKD) trends across 204 countries from 1990 to 2023. CKD prevalence and mortality have risen substantially over three decades, driven primarily by diabetes, hypertension, and aging populations. Low- and middle-income countries bear a disproportionate share of the burden, yet lack adequate treatment infrastructure. The study identifies key modifiable risk factors attributable to a large fraction of CKD deaths and disability-adjusted life years. These findings underscore an urgent need for global strategies targeting early detection, blood pressure control, glycemic management, and equitable access to kidney care to reverse these alarming trends.
Detailed Summary
Chronic kidney disease is a growing global health crisis, and understanding its full scope is essential for directing prevention and treatment resources. Without that clarity, health systems—particularly in resource-limited settings—cannot adequately plan for the millions living with progressive kidney deterioration.
The GBD 2023 Chronic Kidney Disease Collaborators conducted a systematic analysis of CKD prevalence, incidence, mortality, disability-adjusted life years (DALYs), and attributable risk factors across 204 countries and territories from 1990 to 2023. Published in The Lancet in 2025, this large-scale epidemiological effort represents the most current and geographically comprehensive assessment of CKD burden available.
Key findings indicate that CKD burden has increased substantially over the 33-year study period, with rising prevalence tied to the parallel global epidemics of type 2 diabetes and hypertension. Diabetes-related and hypertension-related CKD now account for the majority of attributable risk. Aging populations further amplify burden, as kidney function naturally declines with age. Regional disparities are stark, with sub-Saharan Africa, South Asia, and parts of Latin America experiencing rapid increases without proportional healthcare capacity.
These findings carry major implications for global health policy. Effective management of diabetes and hypertension at the population level is the single most actionable lever for reducing future CKD burden. Early screening programs and nephrology capacity-building in low-income nations are critical unmet needs. The data also reinforce that CKD is not merely a downstream complication but a priority condition warranting dedicated prevention strategies.
Caveats include reliance on modeled estimates where direct epidemiological data are sparse, particularly in low-income regions. Variations in CKD diagnostic criteria and reporting across countries may introduce measurement inconsistency. The abstract-only access limits full assessment of specific numerical findings and subgroup analyses.
Key Findings
- CKD burden increased significantly worldwide from 1990 to 2023, driven by diabetes and hypertension.
- Diabetes and elevated blood pressure are the dominant modifiable risk factors attributable to CKD mortality and DALYs.
- Low- and middle-income countries face disproportionately rising CKD burden with insufficient healthcare infrastructure.
- Aging populations globally amplify CKD prevalence and associated disability.
- Regional disparities in CKD outcomes highlight urgent need for equitable access to kidney care.
Methodology
This is a systematic analysis using the Global Burden of Disease 2023 framework, covering 204 countries and territories from 1990 to 2023. The study modeled CKD prevalence, incidence, mortality, and DALYs using standardized epidemiological methods and attributed burden to specific risk factors. Data sources included vital registration systems, surveys, and published literature, with Bayesian statistical modeling to fill gaps.
Study Limitations
This summary is based on the abstract only; full numerical results, country-specific data, and detailed subgroup analyses were not accessible. Estimates for regions with limited surveillance data rely heavily on statistical modeling, introducing uncertainty. Variability in CKD case definitions and diagnostic thresholds across countries may affect cross-national comparisons.
