对儿童生长轨迹的评估和旨在改善儿童健康的干预措施在很大程度上取决于所使用的生长图表。2000年5月和2006年4月，美国CDC和WHO分别发布了新的增长图表，以取代1977年的NCHS参考。世界卫生组织的图表是第一次基于一个规定的，前瞻性的，国际样本的婴儿选择代表最佳的增长，这篇文章比较了世界卫生组织和疾病预防控制中心的曲线，并评估健康的母乳喂养的婴儿的生长性能，根据两者。正如预期的那样，WHO和CDC图表之间存在重要差异，这些差异因年龄组、生长指标和特定Z评分曲线而异。婴儿期的差异尤其重要，这可能是由于研究设计和样本特征（如喂养类型）的差异所致。总体而言，CDC图表反映的样本比WHO样本更重，但略短。根据世界卫生组织的标准，这导致营养不良率较低（出生后6个月除外），超重和肥胖率较高。健康母乳喂养的婴儿沿着WHO标准的年龄别体重平均Z评分，而从2个月开始在CDC图表上出现动摇。世卫组织标准中较短的测量间隔为监测婴儿早期快速变化的生长率提供了更好的工具。它们的采用将对评估哺乳性能和婴儿喂养的充分性产生重要影响，并将使用于评估生长的工具与美国国家指导方针之间的一致性，该指导方针建议母乳喂养作为婴儿期的最佳营养来源。J.营养137：144-148，2007.
The evaluation of child growth trajectories and the interventions designed to improve child health are highly dependent on the growth charts used. The U.S. CDC and the WHO, in May 2000 and April 2006, respectively, released new growth charts to replace the 1977 NCHS reference. The WHO charts are based for the first time on a prescriptive, prospective, international sample of infants selected to represent optimum growth, This article compares the WHO and CDC curves and evaluates the growth performance of healthy breast-fed infants according to both. As expected, there are important differences between the WHO and CDC charts that vary by age group, growth indicator, and specific Z-score curve. Differences are particularly important during infancy, which is likely due to differences in study design and characteristics of the sample, such as type of feeding, Overall, the CDC charts reflect a heavier, and somewhat shorter, sample than the WHO sample. This results in lower rates of undernutrition (except during the first 6 mo of life) and higher rates of overweight and obesity when based on the WHO standards. Healthy breast-fed infants track along the WHO standard's weight-for-age mean Z-score while appearing to falter on the CDC chart from 2 mo onwards. Shorter measurement intervals in the WHO standards result in a better tool for monitoring the rapid and changing rate of growth in early infancy. Their adoption would have important implications for the assessment of lactation performance and the adequacy of infant feeding and would bring coherence between the tools used to assess growth and U.S. national guidelines that recommend breast-feeding as the optimal source of nutrition during infancy.
