Numerical values for prevalence of obesity are highly dependent on the criteria used to identify the condition and its gradations of severity. Prevalence is also affected by the makeup of the surveyed population. Recently, national surveys of prevalence of obesity in the United States and some European countries have been reported in terms of criteria that permit direct comparison of the findings. When the prevalence of a body mass index is 30 kg/m2 or more in US adults is compared with findings in adults in the United Kingdom, France, the Netherlands, and Italy, the differences are striking, with prevalence ratios ranging from approximately 1.5 (US versus UK) to 3.0 (US versus France).
肥胖患病率的数值高度依赖于用于识别该病症及其严重程度分级的标准。患病率还受到被调查人群构成的影响。最近，美国和一些欧洲国家已按照允许对调查结果进行直接比较的标准报告了全国肥胖患病率调查情况。当将美国成年人中体重指数为30千克/平方米及以上的患病率与英国、法国、荷兰和意大利成年人的调查结果进行比较时，差异显著，患病率比值约为1.5（美国与英国相比）至3.0（美国与法国相比）。
