对世卫组织国际生长参考进行了审查，以确定可能影响对由此得出的人体测量指标的解释的特征。在从其导出参考曲线的两个不同数据集的交点处发现了不连续。此外，Z分数得出的年龄体重和身高体重的百分位数曲线没有连接，因为参考的两个部分的方差不同。从经验上看，对国际营养调查数据的检查显示，在2岁时，低身高、低身高体重和高体重身高的患病率出现了人为的下降，这主要是由于这些不连续，而不是由于营养状况随着年龄的内在变化。根据国际参考的这些特点，讨论了解释人体测量指标的战略。
The WHO international growth reference was reviewed to identify characteristics that might affect the interpretation of anthropometric indicators derived from it. Discontinuities were found at the junction point of the two distinct data sets from which the reference curves are derived. Also, the Z-score derived percentile curves for weight-for-age and weight-for-height did not join due to differences in the variances of the two portions of the reference. Empirically an examination of data from international nutrition surveys revealed an artifactual drop in the prevalence of low height-for-age, low weight-for-height, and high weight-for-height at age 2 y, which is due substantially to these discontinuities rather than to intrinsic changes in nutritional status with age. Strategies are discussed for the interpretation of anthropometric indicators in light of these characteristics of the international reference.
