Uric acid to high-density lipoprotein cholesterol ratio (UHR) is considered a novel marker of inflammation. The aim of this study was to investigate the association between the UHR and chronic kidney disease (CKD) in middle-aged and older adults. This study used data from the National Health and Nutrition Examination Survey (NHANES) and the China Health and Retirement Longitudinal Study (CHARLS). The association between UHR and CKD prevalence was analyzed using weighted multivariable logistic regression models. Restricted cubic spline (RCS) models were used to analyze nonlinear relationships. Weighted subgroup analyses were performed to validate the robustness of the findings. The diagnostic performance of UHR for CKD was evaluated using receiver operating characteristic (ROC) curves. This study included 10,968 participants from NHANES and 9,012 participants from CHARLS. The mean age of NHANES participants was 59.60 years (standard deviation [SD] = 10.97), with 5,575 men (50.83%). CHARLS participants had a mean age of 59.58 years (SD = 9.40), and 4,203 (46.64%) were men. Weighted logistic regression analysis revealed a positive association between UHR and CKD prevalence (CHARLS: OR = 1.83, 95% CI = 1.44–2.32, p < 0.001; NHANES: OR = 1.81, 95% CI = 1.58–2.07, p < 0.001). The RCS regression models demonstrated a significant nonlinear relationship between UHR and CKD. ROC analysis indicated that UHR demonstrated moderate CKD discrimination (CHARLS: AUC = 0.707; NHANES: AUC = 0.6...
