身体组成的方法依赖于不同种族群体之间不恒定的假设。其结果是，所使用的方法需要针对特定人群，以保证得出无偏的结论。或者，应使用化学多室模型或扫描技术等无干扰方法。为了更好地了解肥胖症及其并发症的病因，有必要在少数民族人群中获得关于体脂的充分和公正的科学数据。世界卫生组织目前普遍定义的体重不足、超重、肥胖和脂肪分布的分界点可能需要修订，因为体重指数与身体组成之间的关系以及脂肪分布指数与内脏脂肪实际量之间的关系在各族裔群体中各不相同。例如，几个人群中低体重指数水平的疾病风险升高，证明了需要针对肥胖和脂肪分布的种族特定临界点。需要适当设计和进行研究，以获得关于这些主题的公正信息。Curr Opin Clin Nutr Metab Care 4：377-383.

Body-composition methodologies rely on assumptions that are not constant across ethnic groups. The consequence is that the methods used need to be population specific to guarantee unbiased conclusions. Alternatively, assumption-free methods such as chemical multiple-compartment models or scanning techniques should be used. Adequate and unbiased scientific data on body fat among ethnic population groups are necessary for a better understanding of the aetiology of obesity and its co-morbidities. The World Health Organization cut-off points for underweight, overweight, obesity and fat distribution, now universally defined, may need revision because the relationship between body mass index and body composition, and between indices of fat distribution and the actual amount of visceral fat, differ across ethnic groups. The need for ethnically specific cutoff points for obesity and fat distribution is substantiated, for example, by elevated disease risks at low levels of body mass index in several populations. Properly designed and conducted studies are needed to obtain unbiased information on these topics. Curr Opin Clin Nutr Metab Care 4:377-383. (C) 2001 Lippincott Williams Wilkins.
