Objective: Serum uric acid level has been found to be associated with a risk factor for cardiovascular diseases. However, the topic has not been explored in the general population, especially in Korea. This study was designed to determine whether serum uric acid is associated with carotid atherosclerosis and arterial stiffness in the Korean Multi-Rural Communities Cohort study. Methods: A total of 5568 participants from the Korean Multi-Rural Communities Cohort were evaluated for the risk of hyperuricemia in cardiovascular atherosclerosis. Important surrogates for cardiovascular atherosclerosis such as intimaemedia thickness (IMT) and brachial-ankle pulse wave velocity (baPWV) were assessed. We evaluated the association between these atherosclerosis indices and serum uric acid level or hyperuricemia through multivariate-adjusted logistic and linear regression analyses. Results: There was a significant difference of carotid IMT and baPWV between males and females (p < 0.0001, respectively). Both male and female subjects with hyperuricemia showed higher baPWV than subjects without hyperuricemia (p ¼ 0.0004 for males; p ¼ 0.001 for females). Serum uric acid level was positively correlated with baPWV in males (b ¼ 0.0006, p < 0.0001) and in females (b ¼ 0.0001, p ¼ 0.04), whereas no association between serum uric acid and carotid IMT was found in either gender. A linear relationship of baPWV with increasing serum uric acid level was observed in males (p ¼ 0.0005) and in females (p ¼ 0.004). Conclusion: Serum uric acid level could be considered an important risk factor for arterial stiffness in Korean population, whereas carotid IMT is not associated with serum uric acid in either gender when using data from the Korean Multi-Rural Communities Cohort study. 2013 Elsevier Ireland Ltd.
