目的：研究方法和步骤：2000-2001年，在全国范围内对15,540名成年人进行了横断面调查。由经过培训的观察员测量体重、身高和腰围。超重和肥胖是根据世界卫生组织的分类定义的。结果：男性平均BMI为23.1 kg/m2，女性平均BMI为23.5 kg/m2，女性平均腰围为79.6 cm。超重和肥胖的患病率分别为男性24.1%和2.8%，女性26。女性分别为1%和5.0%。中心性肥胖的患病率男性为16.1%，女性为37.6%。中国北方居民超重、肥胖和向心性肥胖的患病率高于南方，城市居民高于农村。生活方式因素是解释北方和南方居民超重和向心性肥胖差异的最重要危险因素。在女性中，生活方式和饮食是最重要的危险因素，以解释城市和农村居民之间的差异，而社会经济地位，生活方式和饮食都是重要的男性.Discussion：我们的研究表明，超重和肥胖已成为重要的公共卫生问题在中国。环境危险因素可能是造成我国超重和肥胖患病率地区差异的主要原因。
Objective: To examine the prevalence and risk factors of overweight and obesity in China.Research Methods and Procedures: A cross-sectional survey was conducted in a nationally representative sample of 15,540 Chinese adults in 2000-2001. Body weight, height, and waist circumference were measured by trained observers. Overweight and obesity were defined according to the World Health Organization classification. Central obesity was defined according to guidelines of the International Diabetes Federation.Results: Mean BMI and waist circumference were 23.1 kg/m(2) and 79.6 cm, respectively, for men and 23.5 kg/m(2) and 77.2 cm, respectively, for women. The prevalences of overweight and obesity were 24.1% and 2.8% in men and 26. 1 % and 5.0% in women, respectively. The prevalence of central obesity was 16.1 % in men and 37.6% in women. The prevalences of overweight, obesity, and central obesity were higher among residents in northern China compared with their counterparts in southern China and among those in urban areas compared with those in rural areas. Lifestyle factors were the most important risk factors to explain the differences in overweight and central obesity between northern and southern residents. Among women, lifestyle and diet were the most important risk factors to explain the differences between urban and rural residents, whereas socioeconomic status, lifestyle, and diet were all important among men.Discussion: Our study indicates that overweight and obesity have become important public health problems in China. Environmental risk factors may be the main reason for regional differences in the prevalence of overweight and obesity in China.
