ANALYSIS OF NHANES ANTHROPOMETRIC MEASUREMENTS ON CHILDREN

这项研究将开发一种新的身高体重指数，该指数可以根据 孩子的年龄。相对权重指数，如Quetlet和Ponderal 在成人人口上使用的指数对 孩子们。他们往往与年龄密切相关，而不是 身体脂肪的预测。包含年龄的多项式回归模型 这些术语适用于不同年龄段儿童的体重和身高数据 从国家健康和营养检查调查开始的3到12年 为了估算调整后的身高标准体重 对于孩子的年龄来说。单独的回归模型被估计为 男孩和女孩们。建立了一个相对权重指数。 从回归中估计的标准权重。这一相对权重 将指数与三头肌和肩胛骨下皮褶厚度进行比较。这个 新的相对权重指数具有可取的性质 与年龄无关，与皮褶测量高度相关。 推导出的相对权重指数可用于分析 需要一个容易计算的肥胖指数的流行病学研究 在青春期前的孩子中。

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.
