AIMS The objective of this study was to investigate the different associations of the serum urate (SUA) level with cardiovascular and cerebrovascular diseases (CVD), diabetic kidney disease (DKD) and diabetic retinopathy (DR) in Chinese adults. METHODS We analyzed 4,767 participants out of 4813 adults with diabetes enrolled from seven communities in a cross-sectional survey. Participants underwent several medical examinations, including the measurement of anthropometric factors, blood pressure, SUA, glucose, lipid profiles, urine albumin/creatinine ratio (ACR) and fundus photographs. RESULTS Compared with the first SUA tertile, the third tertile increased the prevalence of CVD by 22% (OR 1.22; 95% CI 1.01, 1.46) (P for trend <0.05) and increased the prevalence of DKD by 59% (OR 1.59; 95% CI 1.28, 1.97) for KDOQI definition. Compared with the first tertile, the OR (95% CI) of the number of diabetic complications, ranging from 0 to 2, associated with SUA level in ordinal logistic regression was 1.75 (1.44, 2.12) for the third tertile (P for trend< 0.01). These associations were all fully adjusted. No association was found between the prevalence of DR and the SUA level. CONCLUSIONS A higher SUA level was associated with an increased prevalence of CVD and DKD and a variety of diabetic complications, other than DR, in men and postmenopausal women with T2DM. However, the causation remains to be demonstrated.
