在儿童体重和肥胖研究中使用的术语和测量可能是复杂和令人困惑的。差异出现在度量、术语、参考值和参考级别上。大多数研究依赖于体重和身高计算的身体质量指数（BMI），而不是更直接的身体脂肪测量。超重和肥胖的定义通常是统计上的，而不是基于风险的，并且使用各种不同的BMI参考数据集。因此，不同的定义通常不会给出相同的结果。一个基本问题是缺乏任何一个特定定义的有力证据。与其将这个问题表述为如何定义肥胖，不如考虑一下BMI的哪个临界值最能预测未来的健康风险，以及如何有效地筛查这些风险，这可能会很有用。不同人群的答案可能不同。此外，与其仅仅依靠BMI来做筛查决定，还不如考虑其他因素，不仅包括种族、性别和年龄，还包括家族史等因素，这可能是有用的。尽管存在局限性，但基于bmi的超重和肥胖定义为一般公共健康监测和筛查提供了实用的定义。中国生物医学工程学报，2011,32(2):559 - 566。
Terminology and measures used in studies of weight and adiposity in children can be complex and confusing. Differences arise in metrics, terminology, reference values, and reference levels. Most studies depend on body mass index (BMI) calculated from weight and height, rather than on more direct measures of body fatness. Definitions of overweight and obesity are generally statistical rather than risk-based and use a variety of different reference data sets for BMI. As a result, different definitions often do not give the same results. A basic problem is the lack of strong evidence for any one particular definition. Rather than formulate the question as being one of how to define obesity, it might be useful to consider what BMI cut-points best predict future health risks and how efficiently to screen for such risks. The answers may be different for different populations. In addition, rather than depending solely on BMI to make screening decisions, it is likely to be useful to also consider other factors, including not only race-ethnicity, sex and age, but also factors such as family history. Despite their limitations, BMI-based definitions of overweight and obesity provide working practical definitions that are valuable for general public health surveillance and screening. Adv.
