摘要

导言:尽管越来越多的共识是使用身体质量指数(BMI)截断值对儿童和青少年的肥胖进行分类,但如何定义年轻人的肥胖仍然是一个有争议的问题。目的:本文简要概述了与儿童和青少年肥胖评估相关的问题。结果:目前,BMI可能是最好的测量方法。BMI可以很容易地以低成本进行评估,并且与身体肥胖和健康风险密切相关。然而,作为脂肪组织的间接测量,BMI有一些局限性。Cole等人发表了一套基于6个国家收集的数据而制定的针对性别和年龄的BMI临界值,该参考资料已被推荐在国际上使用。最近,一些研究人员对这一国际参考提出了担忧。有人认为,由于种群之间的生物学差异,应该使用针对特定种群的标准。结论:BMI是一种有效可行的身体肥胖的间接测量方法,但存在一定的局限性。需要更多的努力来制定有效的儿童肥胖分类。

Epidemiology of childhood obesity--methodological aspects and guidelines: what is new?

Introduction: It is still a matter of debate as to how to define obesity in young people, although a growing consensus is to use body mass index (BMI) cutoffs to classify obesity in children and adolescents.

Objective: This article provides a brief overview of issues related to the assessment of obesity in children and adolescents.

Results: At present, BMI is probably the best choice among available measures. BMI can be easily assessed at low cost, and has a strong association with body fatness and health risks. However, as an indirect measure of adipose tissue, BMI has a number of limitations. Cole et al published a set of sex- and age-specific BMI cutoffs, which had been developed based on data collected in six countries, and the reference has been recommended for international use. Recently, several researchers have raised concerns regarding this international reference. It has been argued that population-specific standards should be used due to biological differences between populations.

Conclusion: BMI is a valid and feasible indirect measure of body fatness, but it suffers from a number of limitations. More efforts are needed to develop valid classifications of childhood obesity.
