Serum uric acid and metabolic syndrome in Taiwanese adults

A positive association between serum uric acid and metabolic syndrome has been reported, but little information is available about the association between scrum uric acid and metabolic syndrome in Taiwanese adults. The purpose. of this study was to investigate the association between serum uric acid levels and metabolic syndrome in Taiwanese adults. We performed a cross-sectional study of 2085 men and 1557 women. All of the participants underwent a health screening during the period from January 2005 to December 2005 at a health center of the Shin Kong Wu Ho-Su Memorial Hospital. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The results showed that hyperuricemia was significantly associated with increased risk for hypertriglyceridemia, low high-density lipoprotein cholesterol level, and high blood pressure in men and women. The risk of metabolic syndrome was significantly higher in the fourth quartile than in the first quartile of uric acid level in men (odds ratio [OR], 1.50; 95% confidence interval [Cl], 1.06-2.14) and women (OR, 2.33; 95% Cl, 1.39-3.93). In addition, uric acid level was inversely associated with hyperglycemia in men. The ORs of hyperglycemia for the second, third, and fourth quartile of uric acid were 0.69 (95% Cl, 0.46-1.03), 0.55 (95% Cl, 0.37-0.83), and 0.45 (95% Cl, 0.29-0.69), respectively, compared with the lowest quartile of uric acid. The results demonstrate that. there is a positive association between serum uric acid levels and metabolic syndrome and an inverse association between uric acid and fasting plasma glucose in Taiwanese adults.
