Abstract
Background: Serum uric acid (UA) level has been suggested to be associated with factors that contribute to the metabolic syndrome. However, the association between metabolic syndrome and UA has not been elucidated. We sought to determine the association between serum UA level and the number of components that contribute to the metabolic syndrome, and which component was associated most with higher serum UA level. Methods: A consecutive sample was taken of the health examinations of all hospital staff who were assessed between January 2004 and December 2004 in a medical center. A total of 3,065 subjects aged 18 to 81 years (635 males, 2,430 females) participated. Blood tests and all physical variables were examined using standard methods. Subjects were divided into 5 groups according to their possession of 0,1, 2, 3 or ≥4 components of the metabolic syndrome. The differences in all variables between groups were analyzed by ANOVA. The relationship between serum UA level and the number of metabolic components was determined by linear regression analysis. The contribution to elevated UA of possessing different risk factors was determined by a multivariate linear regression model. Results: Mean serum UA level increased as the number of metabolic factors increased. Serum UA level was higher in subjects with abnormal triglyceride (TG), waist circumference, high-density lipoprotein cholesterol (HDL-C) level and blood pressure (BP), with mean increases in UA level of 22.8, 21.4, 14.4 and 9.4(imol/L, respectively (p< 0.001), compared to subjects with normal levels. After controlling for body mass index, abnormal TG, HDL-C and BP continued to account, in order of influence, for elevated UA. Conclusion: Serum UA level was elevated significantly as the number of metabolic components increased. Abnormal TG had the most influence on serum UA. A prospective study is warranted to determine if the prevention or treatment of hyperuricemia affects the development of metabolic syndrome.Keywords
