背景资料：美国一直是体重指数最高的国家（BMI;单位kg/m2），但缺乏将美国与其他国家进行比较的研究。目的：为了呈现全球肥胖的情况并检查儿童BMI的变化，我检查了澳大利亚、中国、英国、英国和美国的BMI分布上端的男性和女性的BMI数据。设计：作为代表性数据，我使用直接测量的6-18岁儿童和年龄>= 19岁的男性和女性的体重和身高。使用BMI的分位数回归分析来确定结果，年龄、年龄平方和年龄立方的系数代表解释变量，绘制曲线以确定每个年龄组第95百分位数的平均BMI。超重和肥胖的措施，在所有选定的国家，使用全国代表性的调查和第95百分位数的平均BMI，determined.Results：在妇女中，更大的增长被发现在第95百分位数的平均BMI在澳大利亚（+5.7 BMI单位）和英国（+3.7 BMI单位）比在美国（+2.7 BMI单位）在一半的时间。相比之下，在儿童中，年龄较小的中国儿童经历了最大的增长。例如，6岁中国儿童在第95百分位数的平均BMI为24.8（增加5.0），比美国儿童第95百分位数的BMI多2.6个BMI单位。结论：在儿童中，美国儿童在第95百分位数的BMI低于中国，而在女性中，澳大利亚和英国女性正在迅速接近美国女性的BMI。美国临床营养杂志2010;91（增刊）：284 S-8 S。
Background: The United States has been the country with the highest body mass indexes (BMIs; in kg/m(2)) at higher centiles, but research that compares the United States with other nations is lacking.Objective: To present a picture of global obesity and examine the shifts in BMI in children, I examined BMI data for men and women at the upper ends of the BMI distributions in Australia, China, the United Kingdom, and the United States.Design: As representative data, I used directly measured weight and height for children aged 6-18 y and for men and women aged >= 19 y. Quantile regression analysis with BMI was used to determine the outcome, and the coefficients of age, age squared, and age cubed represented the explanatory variables plotted to determine mean BMI at the 95th centile for each age group. Overweight and obesity measures across all selected countries, with the use of nationally representative surveys and the 95th centile mean BMI, were determined.Results: Among women, much larger increases were found in mean BMI at the 95th percentile in Australia (+5.7 BMI units) and the United Kingdom (+3.7 BMI units) than in the United States (+2.7 BMI units) in one-half the time. In contrast, among children, younger Chinese children experienced the largest increase. For example, the mean BMI at the 95th centile for 6-y-old Chinese children is 24.8 (a 5.0 increase), which is 2.6 BMI units more than the BMI at the 95th centile for children in the United States.Conclusions: Among children, BMIs for US children at the 95th centile are below those in China, whereas among women, Australian and UK women are rapidly approaching BMIs found in US women.
