We investigated the longitudinal associations between changes in SUA and eGFR over 10 years in 1222 participants with baseline eGFR ≥ 60 mL/min/1.73 m2.Methods: This was a 10-year retrospective cohort study conducted from 2007 to 2017. Rapid eGFR decline (defined as the highest quartile of change in eGFR between 2007 and 2017) and new-onset kidney disease (defined as an eGFR < 60 mL/min/1.73 m2 at a 10-year follow-up) were examined using multiple logistic regression analysis, adjusted for sex, age, body mass index, systolic blood pressure, SUA, fasting plasma glucose, serum total cholesterol, and triglyceride at baseline.Results: SUA was inversely correlated with eGFR, and the slopes of the SUA-eGFR regression lines were consistently steeper in females than males. A significant inverse correlation was also observed between 10-year changes in SUA and eGFR in both sexes. Multivariate analysis showed that every 1 mg/dL increase in SUA from baseline was associated with higher risk of rapid eGFR decline and new-onset kidney disease (OR 1.25; 95% CI 1.14– 1.33 and OR 1.40; 95% CI 1.26– 1.49, respectively). Furthermore, the subjects in the highest SUA quartile (> 6.0 mg/dL) had a 2.45 times higher risk of rapid eGFR decline (95% CI 1.51– 3.42) compared to those in the lowest SUA quartile (< 3.9 mg/dL).Conclusion: Elevated baseline SUA is an independent risk factor for rapid eGFR decline and new-onset kidney disease in the general population.Keywords: chronic kidney disease, epidemiology, glomerular filtration rate, risk factors, uric acid |
