This study investigates the relationship between hyperuricemia and metabolic syndrome (MS) among males of Han ethnicity in the Xinjiang Uygur Autonomous Region, China. The blood samples were collected from January to May, 2006 in Urumqi. It included 1496 subjects with ages between 20 to 70 years. All these subjects had physical examinations, blood pressure (BP) measurement and analysis for serum uric acid (SUA), fasting blood sugar (FBS), serum triglycer-ide (TG), serum total cholesterol (TC), serum high den-sity lipoprotein (HDL-C) and serum low density lipoprotein (LDL-C) as well as biochemistry assay. The Data were analyzed using the Pearson Chi-Square Test, Independent-Samples T-Test and the Mantel-Haenszel Test for linear trend, respectively. The results show that the prevalence of MS in the present study was 18%. Blood pressure, fasting blood sugar, body mass index (BMI), waist/hip ratio(WHR), TG, TC and LDL-C were significantly higher in the hyperuricemic group than in normal group and these parameters were strongly related to serum uric acid levels. The com-ponents of metabolic syndrome such as obesity, hyper-glycemia, hypertension and dyslipidemia had a close correlation with SUA. The Odds ratios of these meta-bolic diseases in the hyperuricemic group were 3.097 times, 2.633 times, 2.226 times and 3.058 times of the normal SUA group, respectively. They all have a positive correlation with hyperuricemia. Hyperurice-mia is closely linked to the various components of the metabolic syndrome. More emphasis should be put on the evolving control and prevalence of hyperuricemia and metabolic syndrome among males of Han ethnicity in Xinjiang.
