Abstract

Introduction: Dyslipidemia is a known risk factor for chronic kidney disease (CKD). The effects of statins on CKD have already been studied in patients with CKD; however, data on the general population are limited. This study aimed to determine the relationship between statin use and the incidence of CKD in patients with hypercholesterolemia having normal renal function. Methods: A total of 7,856 participants aged 40-79 years at baseline (2009-2010) were included in the final analyses. The participants were divided into statin users (n = 4,168) and statin nonusers (n = 3,668), according to the statin usage. The Cox proportional hazard regression model was used to evaluate the adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for CKD. Results: The median follow-up duration was 5.8 years. A total of 543 cases of CKD (285 cases in males and 258 cases in females) occurred during the study period. The estimated cumulative incidence of CKD was significantly different between male statin nonusers and users (p < 0.001), while it was not statistically significant between female statin nonusers and users (p = 0.126). Compared with statin nonusers, the fully adjusted HRs (95% CIs) for CKD in statin users were 1.014 (0.773-1.330) in males and 1.117 (0.843-1.481) in females. Conclusion: Dyslipidemia is an obvious risk factor for CKD; however, statin use in patients with hypercholesterolemia having normal renal function does not demonstrate a clear relationship with the incidence of CKD.
