OBJECTIVETo analyze the prevalence and risk factors of metabolic syndrome (MS) in Xinjiang Uygur adults.

METHODSWith cluster random sampling, investigations including questionnaire, physical examination and blood testing were performed among 3442 Uygur adults among in Kashgar of Xinjiang on November 2010. Prevalence of MS in groups with different characteristics were calculated and non-conditional logistic regression analysis were used to analyze the risk factors.

RESULTSThe prevalence of MS was 21.2% (728/3442), and the age-adjusted prevalence was 18.5%. The prevalence among males and females was 14.5% (245/1694) (age-adjusted prevalence 12.7%) and 27.6% (483/1748) (age-adjusted prevalence 24.4%) respectively (P < 0.05). The prevalence of MS among 18 to 24 years old and 65 years old and above were 4.3% (21/490) and 28.9% (109/377) respectively. The prevalence of MS increased with age (χ(2) = 204.13, P < 0.05). The prevalence of low blood HDL-C, central obesity, hypertension, hypertriglyceridemia and hyperglycemia was 57.5% (1978/3442), 44.5% (1531/3442), 27.5% (948/3442), 20.2% (696/3442) and 8.6% (297/3442) respectively. Compared to age group 18 - 24, the risk of MS occurrence was higher in age group 25 - 34, 35 - 44, 45 - 54, 55 - 64 and 65 years-old above, the according OR (95%CI) values were 2.29 (1.38 - 3.81), 6.91 (4.31 - 11.09), 10.81 (6.72 - 17.40), 12.52 (7.74 - 20.26) and 10.20 (6.20 - 16.78), respectively. Smoking also increased the risk of MS (OR = 2.35, 95%CI: 1.64 - 3.37).

CONCLUSIONThe prevalence of MS in Xinjiang Uygur was in high level; The prevalence of MS is higher in female than in male; The risk factors of MS included female, age and smoking.
