Objective To study central obesity among middle-aged and elderly residents of Xinjiang Uygur and Han ethnicities, living in rural and urban areas. Methods Multi-stage stratified random cluster sampling approaches were adopted to collect data from 6 areas in Soutbem, Eastern, Northern Xinjiang and Urumqi city community, from July of 2005 to June of 2007. Results 8284 people were investigated to have found that the crude prevalence rate and the adjusted standardized incidence were 50.11% and 55.40% respectively, on central obesity. The figures were higher than the national level, according to the 2000 census age composition of Xinjiang. The prevalence rate of central obesity was higher in males than in females (P<0.05) higher in residents of Uygur than in Han ethnicities(P<0.05). The prevalent rates of the central obesity hypertension, diabetes and dyslipidemia were higher than those of non-obese ones (P<0.05). Conclusion The standardized prevalence rates of central obesity in residents with Xinjiang Uygur and Hart ethnicities were higher than data from the national statistics. Differences were found in ethnicity, gender and age. The prevalence rates of hypertension, diabetes and dyslipidemia in people having central obesity were higher than the non-obese ones.%目的 了解新疆维吾尔(维)族和汉族人群中心性肥胖现患状况、分布特点及几种慢性非传染性疾病(慢性病)在中心性肥胖和非中心性肥胖者之间患病率的比较.方法 2005年7月至2007年6月采用随机分层多级整群抽样方法,随机抽取南疆、东疆、北疆、乌鲁木齐市区50岁以上的汉族及维族中老年人进行调查.结果 共调查新疆维、汉两民族8284人,中心性肥胖的粗患病率为55.40%.按2000年全国人口年龄构成标化,维、汉两民族中心性肥胖的标化患病率为50.11%.其中男性中心性肥胖的患病率高于女性(P<0.05);维族中心性肥胖的患病率均高于汉族(P<0.05).中心性肥胖者高血压、糖尿病、血脂异常的患病率高于腹围正常者(P<0.05).结论 新疆维、汉两民族中心性肥胖的标化患病率明显高于全国平均水平,且存在性别、年龄及民族间差异,中心性肥胖者的高血压、糖尿病、血脂异常患病率均高于非肥胖者.
