ANALYSIS OF NHANES ANTHROPOMETRIC MEASUREMENTS ON CHILDREN

这项研究将制定一个新的身高体重指数， 孩子的年龄。 相对重量指数，如Quetelet和Ponderal 用于成年人的指数并不适用于 孩子 它们往往与年龄密切相关， 预测身体脂肪。 包含年龄的多项式回归模型 项与年龄段儿童的体重和身高数据拟合， 全国健康和营养检查调查的3至12年 II以估计经调整的标准化身高体重 孩子的年龄。 估计了以下各项的独立回归模型： 男孩和女孩。 使用 从回归中估计标准权重。 这种相对重量 将指数与三头肌和肩胛下皮褶厚度测量值进行比较。 的 新的相对重量指数具有令人满意的特性， 与年龄无关，与皮褶测量高度相关。 所导出的相对权重指数可用于分析 流行病学研究需要一个容易计算的肥胖指数 在青春期前的儿童中。

This study will develop a new weight-for-height index which adjusts for the age of the child. Relative weight indices such as Quetelet and Ponderal indices that have been used on adult populations do not work well for children. They tend to be strongly correlated with age and are not predictive of body fat. Polynomial regression models that include age terms were fitted to weight and height data for children between the ages of 3 to 12 years from the National Health and Nutrition Examination Survey II in order to estimate a standardized weight-for-height which is adjusted for the age of the child. Separate regression models were estimated for boys and girls. A relative weight index was established using the estimated standard weights from the regressions. This relative weight index was compared to triceps and subscapular skinfold measurements. The new relative weight index had the desirable properties of being uncorrelated with age and highly associated with skinfold measurements. The derived relative weight index can be used in the analysis of epidemiologic studies that require an easily calculated index of obesity among prepuberty children.
