新疆地区汉族、维吾尔族、哈萨克族成年人群超重和肥胖流行病学调查

目的 了解新疆地区汉族、维吾尔(维)族、哈萨克(哈)族成年人超重、肥胖的流行特点及相关因素.方法 应用四阶段整群随机抽样法,于2007年6月至2010年3月在新疆抽取乌鲁木齐市、克拉玛依市、阜康市、吐鲁番地区、和田地区、伊犁哈萨克族自治州年龄＞35岁样本,统计3个民族间不同民族组、不同年龄组、不同性别组人群的超重率和肥胖患病率,并进行相关因素分析.结果 6个地区共调查16 460人.汉族、维族、哈族总超重率标化后为36.1%,男性和女性超重率标化后分别为39.8%和27.2%.汉族、维族、哈族超重率标化后分别为41.4%、34.9%和32.8%,3个民族总肥胖患病率标化后为26.9%,男性和女性肥胖患病率标化后分别为27.2%和25.5%,汉族、维族、哈族肥胖患病率标化后分别为18.4%、28.9%和40.1%.新疆地区男性超重和肥胖患病率高于女性,差异有统计学意义(x2=135.00,P＜0.05).不同民族人群的超重率和肥胖率不同,汉族人群超重率最高,哈族人群肥胖患病率最高(x2=338.232,P＜0.05);新疆地区超重率和肥胖率随年龄增加呈明显上升趋势,超重率在45～54岁达到高峰,肥胖率在55～64岁达到高峰(x=246.80,P＜0.05).年龄、民族、职业、教育程度、吸烟、饮酒是超重和肥胖的影响因素.结论 新疆地区超重率和肥胖患病率较高,且存在民族差异,汉族男性超重率最高,哈萨克族男性肥胖患病率最高.

Prevalence on overweight and obesity in Han.Uygur and Hazakh in adults from Xinjiang

Objective To investigate the prevalence and distributing feature of overweight and obesity in Han, Uygur and Hazakh population in adults from Xinjiang. Methods Four-stage selected random samples with maternal age at 35 or over were used to analyze the prevalence and distributing feature of self-reported congestive heart failure in different nationalities, age, sex. The sampled adult population were collected from 6 localities(Urumqi, Kelamayi, Fukang, the Turfan Basin locality, Hetian locality, Yili Hazakh autonomous prefecture), 23 municipalities and 7 locality and 5 autonomous counties in Xinjiang. Results 16 460 people were surveyed. The prevalence rates of overweight and obesity were 36.1% and 26.9% in Han, Uygur and Hazakh population in Xinjiang,respectively from February, 2007. The prevalence rates of overweight and obesity were 41.4% and18.4% in Han population, 34.9% and 28.9% in Uygur population, but 32.8% and 40.1% in Hazakh population. The prevalence rate of overweight and obesity was higher in males(x2= 135.00, P＜0.05).The prevalence rates of overweight and obesity were different between different ethnic groups(x2=338.232, P＜0.05). The prevalence of overweight was highest in Han population, with the highest seen in Hazakh population. The prevalence rates of overweight and obesity were increasing with age (x2=246.80,P＜0.05). The overweight rate in 45-54 year olds and the obesity rate in 55-64 year olds reached their peak values. Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Xinjiang were statistically associated with age, educational level, jobs, smoking and alcohol consumption. Conclusion The prevalence rates of overweight and obesity were much higher in the population of Xinjiang but different among ethnicities. The prevalence of overweight was the highest in Han male population and the rate of obesity in Hazakh male population was the highest.
