背景：国际(国际肥胖工作组；IOTF)身体质量指数(BMI)界值被广泛用于评估儿童超重、肥胖和苗条的患病率。根据LMS方法拟合的6个国家的数据，他们将18岁(16、17、18.5、25和30公斤m(-2))的BMI值与各国平均的儿童百分位数联系起来。与世界卫生组织标准不同的是，这些临界值不能用百分位数(如第85位)来表示。方法：为了解决这个问题，我们对以前未发表的6个国家的L、M和S曲线进行了平均，并使用它们得出了与每个BMI值对应的18年以百分位数定义的新的临界值。根据美国和中国的数据，通过测量他们的患病率，将这些新的分界点与原始分界点以及世界卫生组织的标准和参考进行了比较。结果：新的分界点与原始分界点几乎相同，给出的患病率相差
Background: The international (International Obesity Task Force; IOTF) body mass index (BMI) cut-offs are widely used to assess the prevalence of child overweight, obesity and thinness. Based on data from six countries fitted by the LMS method, they link BMI values at 18 years (16, 17, 18.5, 25 and 30 kg m(-2)) to child centiles, which are averaged across the countries. Unlike other BMI references, e.g. the World Health Organization (WHO) standard, these cut-offs cannot be expressed as centiles (e.g. 85th).Methods: To address this, we averaged the previously unpublished L, M and S curves for the six countries, and used them to derive new cut-offs defined in terms of the centiles at 18 years corresponding to each BMI value. These new cut-offs were compared with the originals, and with the WHO standard and reference, by measuring their prevalence rates based on US and Chinese data.Results: The new cut-offs were virtually identical to the originals, giving prevalence rates differing by
