Background
Individuals with chronic kidney disease (CKD) are often unaware of their disease. Efforts to improve CKD awareness would have the most benefit if focused on individuals at highest risk of progression to end-stage kidney disease (ESKD). Therefore, we examined CKD awareness by future risk of ESKD in a representative sample of US adults.
Methods
We assessed the prevalence of CKD awareness among non-pregnant adults (≥ 20 years) with CKD stages 3-4 who participated in the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2016 (n=3,668). CKD awareness was defined by a “yes” answer to the question, “Have you ever been told by a doctor or other health professional that you had weak or failing kidneys?”. The 5-year probability for ESKD was estimated by the 4-variable Kidney Failure Risk Equation. ESKD risk was categorized as minimal (<2%), low (2% to <5%), intermediate (5% to <15%), or high (≥15%). Unadjusted and adjusted trends in prevalence of CKD awareness by ESKD risk group were computed using logistic regression with complex sample survey methods.
Results
Unadjusted CKD awareness was less than 10% among adults with minimal risk and was higher in the intermediate and high ESKD risk groups (approximately 45% and 50%, respectively). CKD awareness within each risk group was stable over time. Similar results were obtained when adjusted for age, sex, race, hypertension status, and diabetes status, and when analysis was limited to the subgroup with hypertension (Figure). Among adults with diabetes, awareness within each risk group was greater but was also stable over time.
Conclusion
Among adults with CKD stages 3–4 with over 15% 5-year risk of ESKD, approximately half were unaware of having kidney disease. CKD awareness was stable over time, demonstrating the need for intensified efforts to increase CKD awareness.
