View abstract on PubMed
Summary
This summary is machine-generated.Chronic kidney disease (CKD) prevalence stabilized in the U.S. after increasing in the early 2000s. This trend held for most groups, indicating a shift in CKD epidemiology.
Area Of Science
- Nephrology
- Public Health
- Epidemiology
Background
- Understanding trends in chronic kidney disease (CKD) prevalence is crucial for healthcare policy and planning.
- Previous data indicated rising CKD rates, necessitating updated trend analysis.
Purpose Of The Study
- To update the trends in the prevalence of chronic kidney disease (CKD) in the United States.
- To analyze CKD prevalence using updated data from the National Health and Nutrition Examination Survey (NHANES).
Main Methods
- A repeated cross-sectional study design was employed.
- Data from the National Health and Nutrition Examination Survey (NHANES) from 1988-1994 and 1999-2012 were analyzed.
- Chronic kidney disease (CKD) stages 3 and 4 were defined by estimated glomerular filtration rate (eGFR) and albumin-creatinine ratio.
Main Results
- The unadjusted prevalence of CKD stages 3 and 4 initially increased but stabilized after 2003-2004.
- Adjusted prevalence showed no significant difference between 2003-2004 and 2011-2012 across demographic groups.
- This stabilization was observed across most subgroups and with an expanded CKD definition including albuminuria.
Conclusions
- Contrary to previous trends, the prevalence of CKD stages 3 and 4 has not significantly increased in the U.S. population over the last decade.
- The findings suggest a potential plateau in CKD prevalence, impacting future public health strategies.
