背景肥胖已成为一种世界性的流行病。最近，世卫组织承认迫切需要使用标准化的国际标准来检查各国的儿童肥胖症。在成人中的研究发现肥胖和社会经济因素（SES）因素是相关的，但结果不一致的儿童。使用国际标准，我们研究了肥胖的患病率和比较SES因素和肥胖之间的关联countries.Methods在美国（NHANES III，1988-1994年），中国（1993年），俄罗斯（1992年）的全国性调查6-18岁的儿童的数据。我们使用最近更新的美国NCHS体重指数（BMI = wt/ht（2））参考来定义肥胖（BMI大于或等于第95百分位数）和超重（第85百分位数小于或等于BMI <第95百分位数）。世卫组织建议为国际使用提供早期版本的NCHS参考。结果肥胖和超重的患病率在美国分别为11.1%和14.3%，在俄罗斯分别为6.0%和10.0%，在中国分别为3.6%和3.4%。肥胖与社会经济地位之间的关系因国家而异。较高的SES科目更有可能，肥胖在中国和俄罗斯，但在美国低SES组的风险更高，肥胖是在中国的城市地区，但在农村地区在Russian.Conclusions儿童肥胖正在成为一个全球性的公共卫生问题，但肥胖的患病率在不同的社会经济发展水平的国家有显着差异。不同的社会经济地位群体面临不同的风险，肥胖与社会经济地位之间的关系因国家而异。
Background Obesity has become a worldwide epidemic. Recently WHO acknowledged an urgent need to examine child obesity across countries using a standardized international standard. Studies in adults find obesity and socioeconomic factors (SES) factors are correlated, but results are inconsistent for children. Using an international standard, we examined the prevalence of obesity and compared the associations between SES factors and obesity across countries.Methods Data for children aged 6-18 from nationwide surveys in the US (NHANES III, 1988-1994), China (1993), and Russia (1992) were used. We used the recently updated US NCHS body mass index (BMI = wt/ht(2)) reference to define obesity (BMI greater than or equal to 95th percentile) and overweight (85th less than or equal to BMI < 95th percentile). The WHO recommends an early version of the NCHS reference for international use. We conducted logistic analyses to examine the relationship between SES and obesity.Results The prevalence of obesity and over-weight was 11.1% and 14.3%, respectively, in the US, 6.0% and 10.0% in Russia, and 3.6% and 3.4% in China. The relationship between obesity and SES varied across countries. Higher SES subjects were more likely,to be obese in China and Russia, but in the US low-SES groups were at a higher risk, Obesity was more prevalent in urban areas in China but in rural areas in Russia.Conclusions Child obesity is becoming a public health problem worldwide, but the prevalence of obesity varies remarkably across countries with different socioeconomic development levels. Different SES groups are at different risks, and the relationship between obesity and SES varies across countries.
