Childhood obesity is considered a major issue because of its high prevalence and because of its severe consequences on adult health. Prevalence studies are carried out in numerous countries. Analysis of time trends and geographic comparisons are particularly useful, as they may help to identify factors promoting obesity. These studies require adequate definitions of nutritional status and standardized protocols, but in practice, the references, cut-offs and the terminology used vary considerably, and consequently ambiguous information may be found in the literature. Recommendations for the definition of childhood obesity were previously published in 1995 by the European Childhood Obesity Group (ECOG), but new references appeared later. A clarification of the different definitions was needed. Currently used classifications of nutritional status in children are summarized, and recommendations for the references, cut-offs and terms to be used in different contexts are provided. These new ECOG recommendations should help harmonize the various protocols and improve comparisons between studies.
儿童肥胖因其高患病率以及对成人健康的严重影响而被视为一个重大问题。许多国家都开展了患病率研究。对时间趋势的分析和地理比较尤为有用，因为它们可能有助于识别促使肥胖的因素。这些研究需要对营养状况有恰当的定义和标准化的方案，但在实际操作中，所采用的参考标准、临界值和术语差异很大，因此文献中可能会出现模糊不清的信息。欧洲儿童肥胖研究小组（ECOG）曾于1995年发布过关于儿童肥胖定义的建议，但后来出现了新的参考标准。需要对不同的定义进行澄清。本文总结了目前使用的儿童营养状况分类方法，并针对不同背景下应使用的参考标准、临界值和术语提供了建议。这些新的ECOG建议应有助于统一各种方案，并改善研究之间的比较。
