What is the prevalence of Chronic Kidney Disease?

Chronic Kidney Disease (CKD) is a global health concern affecting an estimated 10% to 15% of the adult population worldwide, making it a common condition rather than a rare disease. Because Chronic Kidney Disease often remains asymptomatic in its early stages, many individuals are unaware of their diagnosis, leading to significant variations in reported prevalence data across different regions.

How common is Chronic Kidney Disease?

Chronic Kidney Disease is widely prevalent, with the Global Burden of Disease study estimating that over 850 million people are living with some form of kidney damage globally. Unlike rare conditions, Chronic Kidney Disease is a major public health priority, though its true prevalence is likely higher than reported due to the "silent" nature of early-stage renal decline. Within the DiseaseMaps.org community, 37 individuals have shared their personal experiences with Chronic Kidney Disease, highlighting the necessity of peer support in managing this long-term condition.

What factors influence the prevalence of Chronic Kidney Disease?

The distribution of Chronic Kidney Disease is influenced by several demographic and clinical factors, including:

• Age: Prevalence increases significantly with age; it is most commonly diagnosed in adults over the age of 60.


• Gender: Data from the NIH suggests that women are slightly more likely to be diagnosed with Chronic Kidney Disease than men, though men are more likely to progress to end-stage renal disease (ESRD).


• Ethnic Disparities: In the United States, African Americans, Hispanic Americans, and Native Americans experience a higher prevalence of Chronic Kidney Disease, often linked to higher rates of diabetes and hypertension.


• Comorbidities: The rise in metabolic syndromes, specifically Type 2 diabetes and hypertension, remains the primary driver for the increasing incidence of Chronic Kidney Disease worldwide.

Why is accurate data for Chronic Kidney Disease difficult to obtain?

Accurate tracking of Chronic Kidney Disease is challenged by underdiagnosis, as many patients do not present with symptoms until their glomerular filtration rate (GFR) has dropped significantly. Furthermore, diagnostic criteria can vary between healthcare systems, and clinical registries often focus on advanced stages of Chronic Kidney Disease, frequently overlooking those in the early, manageable phases of the illness.

Next steps

• Consult a nephrologist to assess your kidney function through eGFR and albumin-to-creatinine ratio (ACR) tests.


• Manage underlying conditions like blood pressure and blood sugar, which are the leading causes of Chronic Kidney Disease progression.
