BACKGROUND: Uric acid levels are increased in patients with kidney dysfunction. We tested the hypothesis that uric acid may be associated with kidney disease progression.
STUDY DESIGN: Cohort study.
SETTING & PARTICIPANTS: 5,808 participants of the Cardiovascular Health Study.
PREDICTOR: Uric acid levels.
OUTCOMES & MEASUREMENTS: Kidney disease progression was defined as a decrease in estimated glomerular filtration rate (GFR) of 3 mL/min/1.73 m(2) per year or greater (>or=0.05 mL/s) and as incident chronic kidney disease (CKD). Measures of kidney function were estimated GFR using the Modification of Diet in Renal Disease Study equation.
RESULTS: Higher quintiles of uric acid levels were associated with greater prevalences of estimated GFR less than 60 mL/min/1.73 m(2) (<1.00 mL/s) of 7%, 14%, 12%, 25%, and 42% for quintiles 1 (
LIMITATIONS: Measurements of albuminuria were not available.
CONCLUSIONS: Uric acid levels are associated strongly with prevalent CKD. In comparison, greater uric acid levels had a significant, but much weaker, association with progression of kidney disease.
