title: [Epidemiological characteristics of dyslipidemia in remote rural areas of Xinjiang, 2009-2010].
abstract: Objective:This study aimed to estimate the prevalence of dyslipidemia, hypertriglyceridemia, hypercholesterolemia, high blood low density lipoprotein cholesterol (LDL-C), and low blood high density lipoprotein cholesterol (HDL-C) in remote rural areas of Xinjiang and analyze these indicators' epidemiological characteristics.Methods:A survey of 13 000 individuals (aged ≥18 years) was conducted using a four-stage cluster random sampling method in Jiashi, Xinyuan, Aheqi, and Shawan Counties, Xinjiang, in 2009-2010. After nonpermanent residents were excluded, 12 154 individuals were included in this study. Questionnaire and physical examinations were conducted, including collection of fasting blood to detect TG, TC, LDL-C, and HDL-C. The results were calculated after complex weighting and compared according to the prevalence of different gender and age groups.Results:The overall levels of TG, TC, LDL-C, and HDL-C were 1.34±1.09, 4.45±1.16, 2.36±0.86, and 1.37±0.58 mmol/L, respectively. After complex weighting, the overall prevalence of dyslipidemia was 35.4%; that among men (42.9%) was greater than that among women (29.5%; χ2=234.19,P<0.001), and the prevalence was 35.9%, 34.5%, and 35.1% (χ2=1.52,P=0.467) in participants aged 18-44, 45-59, and ≥60 years, respectively. The overall prevalence of hypertriglyceridemia was 11.4%; that among men (13.5%) was greater than that among women (9.8%; χ2= 40.72,P<0.001), and the prevalence was 9.6%, 13.0%, and 13.2% (χ2=38.71,P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of hypercholesterolemia was 5.7%; that among men(5.0%) was greater than that among women (6.2%; χ2=6.95,P=0.008), and the prevalence was 3.5%, 7.4%, and 8.4% (χ2=105.24,P<0.001) in participants aged 18-4, 45-59, and ≥60 years, respectively. The prevalence of high blood LDL-C was 2.8%, and there was no significant difference between men (3.0%) and women (2.4%; χ2=1.43,P=0.231); the prevalence was 3.5%, 7.4%, and 8.4% (χ2=42.81,P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of low blood HDL-C was 24.0%; that among men (31.6%) was greater than that among women (18.0%; χ2=304.02,P<0.001), and the prevalence was 27.8%, 20.6% and 19.5% (χ2=96.61,P<0.001) in participants aged 18-44, 45-59, and ≥ 60 years, respectively.Conclusions:Low blood HDL-C was the main type of dyslipidemia among the population in remote rural areas of Xinjiang. The prevalence of dyslipidemia among men was greater than that among women, and there was a trend of younger men than women showing dyslipidemia.
