To present a clinical version of the 2000 Centers for Disease Control and Prevention (CDC) growth charts and to compare them with the previous version, the 1977 National Center for Health Statistics (NCHS) growth charts.
The 2000 CDC percentile curves were developed in 2 stages. In the first stage, the empirical percentiles were smoothed by a variety of parametric and nonparametric procedures. To obtain corresponding percentiles and z scores, we approximated the smoothed percentiles using a modified LMS estimation procedure in the second stage. The charts include of a set of curves for infants, birth to 36 months of age, and a set for children and adolescents, 2 to 20 years of age.
The charts represent a cross-section of children who live in the United States; breastfed infants are represented on the basis of their distribution in the US population. The 2000 CDC growth charts more closely match the national distribution of birth weights than did the 1977 NCHS growth charts, and the disjunction between weight-for-length and weight-for-stature or length-for-age and stature-for-age found in the 1977 charts has been corrected. Moreover, the 2000 CDC growth charts can be used to obtain both percentiles and z scores. Finally, body mass index-for-age charts are available for children and adolescents 2 to 20 years of age.
The 2000 CDC growth charts are recommended for use in the United States. Pediatric clinics should make the transition from the 1977 NCHS to the 2000 CDC charts for routine monitoring of growth in infants, children, and adolescents.
展示2000年美国疾病控制与预防中心（CDC）生长图表的临床版本，并将其与先前版本，即1977年国家卫生统计中心（NCHS）生长图表进行比较。
2000年CDC百分位数曲线分两个阶段制定。在第一阶段，通过各种参数和非参数程序对经验百分位数进行平滑处理。为了获得相应的百分位数和z分数，我们在第二阶段使用改良的LMS估计程序对平滑后的百分位数进行近似。这些图表包括一组针对出生至36个月婴儿的曲线，以及一组针对2至20岁儿童和青少年的曲线。
这些图表代表了居住在美国的儿童的横断面；母乳喂养婴儿是根据他们在美国人群中的分布情况来呈现的。2000年CDC生长图表比1977年NCHS生长图表更紧密地匹配出生体重的全国分布，并且1977年图表中发现的身长别体重与身高别体重或年龄别身长与年龄别身高之间的脱节已得到纠正。此外，2000年CDC生长图表可用于获取百分位数和z分数。最后，提供了2至20岁儿童和青少年的年龄别体重指数图表。
建议在美国使用2000年CDC生长图表。儿科诊所应从1977年NCHS图表过渡到2000年CDC图表，以对婴儿、儿童和青少年的生长进行常规监测。
