客观化
为了更好地描述儿童成长的特征，并进一步评估当前国家卫生统计中心和世界卫生组织国际成长参考的潜在局限性。
设计
用最小二乘法进行曲线拟合，用偏度(L)、中位数(M)和变异系数(S)3条曲线来总结身高和体重分布的变化。采用一系列多项式回归方法对L曲线、M曲线和S曲线进行了平滑处理。
设置
这项研究参考了来自18个州的子集数据，这些数据向疾病控制和预防中心的儿科营养监测系统提供临床数据。
方法
我们只选择那些儿童身高和体重分布与第一次和第二次全国健康与营养检查调查密切匹配的诊所。
结果
与目前的国际生长参考不同，新的参考在24个月大时没有分离，因为它基于0至59个月儿童的单一数据来源。该参考文献还比目前的国际参考文献更好地描述了婴儿的生长发育，我们用国家健康和营养检查调查、1995年儿科营养监测系统和戴维斯地区哺乳、婴儿营养和生长研究的数据证明了这一事实。
结论
目前的国家卫生统计中心和世界卫生组织国际增长参考资料需要更新。这项研究中使用的方法将有助于评估其他数据集和评估未来对生长参考的修改。
OBJECTIVE
To better characterize childhood growth and further assess potential limitations of the current National Center for Health Statistics and World Health Organization international growth reference.
DESIGN
The LMS method was used for curve fitting to summarize the changes in height and weight distributions by 3 curves representing the skewness (L), median (M), and coefficient of variation (S). A series of polynomial regression procedures was applied to smooth the L, M, and S curves.
SETTING
Subset data from 18 states contributing clinic data to the Centers for Disease Control and Prevention Pediatric Nutrition Surveillance System were used for this research reference.
METHODS
We chose only those clinics in which the height and weight distributions of children closely matched with those of the first and second National Health and Nutrition Examination Surveys.
RESULTS
Unlike the current international growth reference, the new reference has no disjunction at 24 months of age because it is based on a single data source for children aged 0 to 59 months. The reference also better characterizes the growth for infants than the current international reference, a fact we demonstrated with data from the National Health and Nutrition Examination Surveys, Pediatric Nutrition Surveillance System 1995, and the Davis Area Research on Lactation, Infant Nutrition, and Growth studies.
CONCLUSIONS
The current National Center for Health Statistics and World Health Organization international growth reference needs to be updated. The methods used in this study will be useful to evaluate other data sets and to evaluate future modifications of growth references.
