三峡农村地区人群超重肥胖的流行现状及其影响因素

Current Epidemic Status With Related Factors for Overweight and Obesity in Rural Area of Three Gorges

目的:了解三峡农村地区超重肥胖的流行现状和影响因素。方法:于2007年在宜昌市夷陵区的农村人群进行现况调查,采用标准化的问卷收集居民一般人口学情况、社会经济状况和生活方式与行为,并进行身高、体重和腰围测量。超重、肥胖和中心性肥胖分别定义为体重指数(BMI):24.0～27.9 kg/m2、≥28 kg/m2和腰围≥85 cm(男性)、≥80 cm(女性)。采用Logistic回归模型探讨影响超重肥胖的相关因素。结果:共调查35岁及以上者9568人(应答率为80.8%),其中19.7%为三峡大坝建设后靠移民。年龄标化超重、肥胖和中心性肥胖患病率在男性分别为22.2%、5.5%和18.8%,女性分别为26.7%、6.9%和25.4%,男性各指标明显低于女性(P值均<0.01)。在男性中35～54岁年龄段超重肥胖患病率最高,而女性患病率最高的年龄段为45～64岁。三峡移民超重肥胖患病率指标显著高于非移民(P值<0.01或<0.05)。多元Logistic回归分析表明,受教育水平较高、经常食用高脂食物、缺乏体力活动和从事非农业生产者罹患超重/肥胖(BMI≥24)的风险明显增加(P值均<0.05),而移民与否不是超重肥胖的独立影响因素。结论:三峡夷陵农村地区超重肥胖患病率较高,需大力加强肥胖的防治。

Objective ： To study the current epidemic status with related factors for overweight and obesity in rural area of Three Gorges. Methods：We conducted a cross-sectional survey in 2007 in rural area of Three Gorges at Yiling district. We used the standard structure questionnaire to collect the information of 9568 local participants with the age of 35 years or older for their socialeconomic status ,life-styles and demographic data, and measured their body weight, height and waist circumference. Overweight and obesity were defined as body mass index （BMI） at （24 -27.9）kg/m^2 and BMI 28 kg/m^2 respectively, central obesity was defined as waist circumference 85 cm in male, 80 cm in female. The overweight and obesity with the related factors were assessed by multi logistic regression analysis. Results：The survey had 80. 8% of response, and 19. 7% of them were the migrants of Three Gorges. The age-adjusted prevalence of overweight,obesity and central obesity in male were 22. 2% ,5.5% and 18.8% ,in female were 26. 7% ,6. 9% and 25.4% , all the index in male were lower than those in female, P〈0. 01 respectively. The highest rates of overweight and obesity were at 35 - 54 years of age in male, and at 45 - 64 years in female. The prevalence of overweight and obesity were higher in migrants than non-migrants （P〈0. 01 or P〈0. 05 ）. Multi logistic regression analysis showed that there were higher risks of overweight and obesity in the population with the higher education,less physical activity and more fat diet,P〈0. 05 respectively. Immigration was not the independent risk factor for overweight and obesity. Conclusion：The prevalence of overweight and obesity were relatively high in rural of Three Gorges at Yiling district. Great effort should be made to prevent and control this phenomenon.
