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.
对世界卫生组织国际生长参考标准进行了审查，以确定可能影响从中得出的人体测量指标解释的特征。在参考曲线所源自的两个不同数据集的交汇点发现了不连续性。此外，由于参考标准两部分方差的差异，年龄别体重和身高别体重的Z分数衍生百分位数曲线并未衔接。根据国际营养调查的数据进行的实证研究表明，2岁时年龄别身高低、身高别体重低和身高别体重高的患病率出现人为下降，这主要是由于这些不连续性，而非营养状况随年龄的内在变化。针对国际参考标准的这些特征，讨论了人体测量指标解释的策略。
