Prevalence of Metabolic Syndrome, Insulin Resistance, Impaired Fasting Blood Glucose, and Dyslipidemia in Uygur and Kazak Populations

This study was designed to evaluate the prevalence of the metabolic syndrome (MetS), impaired fasting blood glucose (IFG), insulin resistance (IR), hypertriglyceridemia (HTG), and low high-density lipoprotein cholesterol (HDL-C) in adult Uygur and Kazak populations. Questionnaires, blood pressure, anthropometric measurement, and fasting glucose were evaluated. The age-adjusted prevalence of MetS and IFG was 3.43- and 1.47-fold higher, respectively, in Uygurs compared with Kazaks. The prevalence of IR and HTG was 1.33- and 2.22-fold higher, respectively, in Uygurs compared with Kazaks. In addition, the prevalence of low HDL-C was 4.05-fold higher in Uygurs compared with Kazaks. These data depicted greater risk for cardiometabolic syndrome in Uygurs compared with Kazaks. In addition, all prevalence with the exception of low HDL-C was greater in men compared with women in both ethnic groups. For body mass index (BMI)<24, 24 to 28, and ≥28 kg/m2, the prevalence of MetS, HTG, and low HDL-C was higher in Uygurs than Kazaks at the same BMI level. For individuals with a BMI between 24 and 28, the prevalence of IR but not IFG was significantly greater in Uygurs than Kazaks. At BMI≥28, neither IFG nor IR was overtly different between the two ethnic groups.
