Objectives

This report provides detailed

information on how the 2000 Centers

for Disease Control and Prevention

(CDC) growth charts for the United

States were developed, expanding

upon the report that accompanied the

initial release of the charts in 2000.

Methods

The growth charts were developed

with data from five national health

examination surveys and limited

supplemental data. Smoothed

percentile curves were developed in

two stages. In the first stage, selected

empirical percentiles were smoothed

with a variety of parametric and

nonparametric procedures. In the

second stage, parameters were created

to obtain the final curves, additional

percentiles and z-scores. The revised

charts were evaluated using statistical

and graphical measures.

Results

The 1977 National Center for Health

Statistics (NCHS) growth charts were

revised for infants (birth to 36 months)

and older children (2 to 20 years). New

body mass index-for-age (BMI-for-age)

charts were created. Use of national

data improved the transition from the

infant charts to those for older children.

The evaluation of the charts found no

large or systematic differences between

the smoothed percentiles and the

empirical data.

Conclusion

The 2000 CDC growth charts were

developed with improved data and

statistical procedures. Health care

providers now have an instrument for

growth screening that better represents

the racial-ethnic diversity and

combination of breast- and formulafeeding in the United States. It is

recommended that these charts replace

the 1977 NCHS charts when assessing

the size and growth patterns of infants,

children, and adolescents.

Introduction

The National Center for Health

Statistics (NCHS) growth charts

that have been in use since 1977

have been revised. The revised version,

known as the Centers for Disease

Control and Prevention (CDC) Growth

Charts: United States released in 2000,

is recommended for use in clinical

practice and research to assess size and

growth in U.S. infants, children, and

adolescents (1).

The 2000 CDC Growth Charts

consist of a set of charts for infants,

birth to 36 months of age and a set of

charts for children and adolescents from

ages 2 to 20 years. The charts for

infants include sex-specific smoothed

percentile curves for weight-for-age,

recumbent length-for-age, head

circumference-for-age, and weight-forrecumbent length; the charts for children

and adolescents include weight-for-age,

stature-for-age, and body mass index

(BMI)-for-age curves. The BMI-for-age

charts represent a new tool that can be

used by health care providers for the

early identification of children who are

at risk for becoming overweight at older

ages. The 2000 CDC Growth Charts

also include weight-for-stature charts for

statures ranging from 77 to 121 cm,

primarily intended for use among

children from ages 2 to 5 years. A

listing of the 1977 NCHS charts and the

2000 CDC charts is shown in table A.

Historical Background

Anthropometric data are valuable

objective indicators of attained size and

physical growth in children. A variety of

growth references were developed and

used in the United States since the early

1900s. Most of these earlier references

have considerable limitations, including

lack of coverage for infants and

preschool children and limited

representation of ethnic, genetic,

socioeconomic, environmental, and

geographic variability (2). From

1946–1976, the Stuart/Meredith Growth

Charts were widely used. These charts

were derived from stature and weight

measurements taken on white children

living near Iowa City, Iowa, or in

Boston, Massachusetts, from 1930 to

1945 (3). The sample sizes were

relatively small and the smoothed

percentile lines were reportedly based

on mathematical approximations of

curves smoothed by hand (4). Thus, the

data did not represent the diversity of

children residing in the United States

and statistical curve-fitting procedures

were not used.

The impetus for the development of

the 1977 NCHS Growth Charts began in

1971, when a study group sponsored by

the American Academy of Pediatrics and

the Maternal and Child Health Program

of the Bureau of Community Health

Services, U.S. Public Health Service,

recommended new growth charts, based

on data from the NCHS Health

Examination Surveys, for the clinical

assessment of infants and children (5).

Subsequently, in 1974, the Food and

Nutrition Board of the National

Academy of Sciences made similar

recommendations, emphasizing the need

for new growth charts for infants and

children based on nationally

representative survey data, to be

supplemented with data collected from

infants in the Fels Longitudinal Growth

Study (6). These recommendations were

further supported in 1975 by a study

group sponsored by the National

Institute of Child Health and Human

Development, National Institutes of

Health (7).

Growth charts for the United States

were developed by NCHS when

nationally representative cross-sectional

survey data became available for most

of the pediatric age range (8). Data from

the National Health Examination Survey

(NHES) II (1963–65) for ages 6–11

years, NHES III (1966–70) for ages

12–17 years, and the first National

Health and Nutrition Examination

Survey (NHANES) I (1971–74) for ages

1–17 years were used to develop these

charts. National survey data were not

available for the period from birth to 1

year. Therefore, the national survey data

were supplemented with data from the

longitudinal growth study of the Fels

Research Institute in Yellow Springs,

Ohio. To avoid pooling multiple diverse

data sets in the 1977 NCHS charts for

birth to 3 years, the infant charts were

based solely on the Fels data. The 14

sex-specific growth charts developed for

infants birth to age 36 months and older

children from ages 2 to 18 years are

generally referred to as the 1977 NCHS

Growth Charts (2,8,9).

In 1978 CDC produced a

normalized version of the NCHS

curves (10,11). The World Health

Organization (WHO) subsequently

recommended these normalized charts

for international applications (12–14).

These normalized versions of the 1977

charts are thus sometimes referred to as

the NCHS/WHO, CDC/WHO, or

NCHS/CDC/WHO growth charts.

Following the recommendation of

Waterlow, et al., this version enabled the

expression of body measurements in

terms of standard deviations from the

median or z-scores (15). Z-scores

facilitate comparisons across ages and

allow the mean and standard deviation

to be calculated for a group of

measures. Another advantage of the

normalized charts was the ability to

describe the relative status of children at

extremes of the distributions.

Although the normalized charts

allowed users a means to better quantify

growth at the extremes, normalization

does not refer to an improved

instrument to qualify growth as

‘‘normal’’ or as a ‘‘standard’’ for growth.

Both the 1977 smoothed percentiles and

the 1978 normalized growth curves are

growth references. They allow the

growth status of a child, or a group of

children, to be compared with that of a

reference population. The 1978

normalized curves are similar to, but not

identical with the 1977 smoothed

percentiles.

Concerns Surrounding the

1977 Charts

Since the development of the 1977

NCHS Growth Charts, a number of

concerns have been raised about various

aspects of the charts and the procedures

used in their development (10,16–23).

Most of these concerns centered on the

infant charts and were largely associated

with characteristics of the Fels data. The

Fels data came from a single

longitudinal study of mainly formulaTable A. Charts included in the 1977 NCHS Growth Charts and in the 2000 CDC Growth

90 to 137 cm and under 10.0 years of age. They are not applicable for any child showing the earliest signs of pubescence. The

revised charts have no similar age or pubescence restrictions. Although the revised charts were developed for children 2 to 5 years

of age, in practice they may accommodate some shorter children with chronologic ages 5.0 years and over.

fed, white middle-class infants in a

limited geographic area of southwestern

Ohio, collected 1929–75. In addition to

not being from a nationally

representative sample, the Fels

observations were made at birth and 1

month, at 3-month intervals from 3 to

12 months, and at 6-month intervals

from 12 to 36 months. These intervals

may be inadequate to properly identify

growth patterns during periods of rapid

change. The Fels birthweights may not

match more recent national birthweight

distributions, and differences between

recumbent length and stature may have

been too large, suggesting limitations in

the recumbent length data. Moreover,

size and growth patterns of Fels infants

may not adequately represent current

growth patterns of combined breast- and

formula-fed infants in the population

(8,18,19,21,22). In addition, differences

between the recumbent length

measurements for infants from the Fels

data and the stature measurements from

the NCHS data sets lead to inconsistent

percentile estimates from the 1977

charts when the transition is made from

recumbent length to stature between 24

and 36 months of age. Other concerns

included the limited ability to assess

size and growth at extremes beyond the

5th and 95th percentiles, the absence of

weight-for-stature references for

adolescents, and the inability to assess

growth at ages 18 years and over (16).

The Revision

The 1977 charts were revised in

part because more recent and

comprehensive national data on body

measurements in U.S. children were

available. After the 1977 NCHS Growth

Charts were developed, additional

national survey data became available

from the NHANES II (1976–80)

beginning at 6 months of age, and from

the NHANES III (1988–94) beginning

at 2 months of age (24,25). During the

planning of NHANES III, increasing

awareness of the concerns surrounding

the 1977 NCHS Growth Charts

influenced the decision to oversample

children ages 2 months to 6 years.

The objective of the revision

process was to use improved statistical

smoothing procedures, in conjunction

with more comprehensive national

survey data, to provide a better

instrument for health care providers who

evaluate the growth status of children in

the United States (16). The Advance

Data report summarizing the

development of the revised growth

charts was issued in 2000 (1). The

present report is designed to expand on

the content of the initial report and

provide more detailed information on

the development of the revised CDC

growth charts for the United States,

including the process, the data sources,

the statistical procedures that were

followed, and the results of statistical

evaluations for the revised charts.

II (1976–80), and III (1988–94). The

survey designs are based on stratified,

multistage probability samples of the

civilian, noninstitutionalized population

in the 48 contiguous States (NHES II,

NHES III, NHANES I) or all 50 States

(NHANES II, NHANES III). All

surveys consisted of a home interview

and a standardized physical examination

conducted in a mobile examination

center. Age was calculated as age at the

time of examination when the

anthropometric data were recorded.

Children ages 6–11 years from NHES

II, 12–17 years from NHES III, 1–19

years from NHANES I, six months–19

years from NHANES II, and 2

months–19 years from NHANES III

were included in the revision. The small

number of children in NHES II who had

their 12th birthday after the home

interview and before the examination

and those who had their 18th birthday

after the home interview and before the

examination in NHES III were also

included. Although the revised growth

charts for older children were developed

for ages from 2 to 20 years, additional

NHANES data for individuals younger

than 2 years and older than 20 years

were included in the analysis to improve

estimates at the lower and upper

boundaries (table C). Detailed

descriptions of these surveys have been

provided (25–29).

Anthropometric procedures

developed for NHANES III are

documented on videotape

URL: http://www.cdc.gov and in the

NHANES III procedures manual (30).

The procedures were consistent with

published recommendations for

standardized anthropometric

techniques (31). The NHANES III

measurement techniques for weight,

recumbent length, stature, and head

circumference were based on

procedures used in the previous NHES

and NHANES surveys, and either the

same or comparable measuring

equipment was used across the

surveys.

obtained from other sources were

incorporated at birth and during the first

few months of life where national data

were either not available or were

insufficient (table C). The infant

weight-for-age curves included national

birthweight distributions taken from

birth certificates for more than 83

million infants born in the United States

between 1968–80 and 1985–94,

corresponding to years in which infants

in the national surveys were born. Birth

length data were only available from

two States, Wisconsin and Missouri.

These States recorded this information

on birth certificates for 890,000 infants

born between 1989 and 1994. These

data were used in the development of

the length-for-age and weight-for-length

curves. Additionally, a limited amount

of data from the CDC Pediatric

Nutrition Surveillance System (PedNSS)

was used in the length-for-age charts.

The majority of infant data in the

PedNSS system come from clinical

records of the Special Supplemental

Nutrition Program for Women, Infants

and Children (WIC) (20). Because the

PedNSS data are not nationally

representative, a subset of the PedNSS

data collected from 1975 to 1995 was

used. Clinics were selected for inclusion

based on three specific conditions. First,

the mean lengths and weights had to be

within ±0.5 cm and ±0.5 kg of the mean

from NHANES II and III combined for

each single month of age from age 3 to

11 months. Second, the clinics had to

have a SD within ±0.2 cm and ±0.2 kg

of the SDs in the combined NHANES II

and III. Finally, the skewness in weight

distribution of the selected clinics’

population had to be within ±0.3 kg of

the skewness of weight in the combined

NHANES II and III. A total of 213

PedNSS clinics were selected, resulting

in a sample of 14,846 observations at

0.5 months, 8,825 at 1.5 months, 5,240

at 2.5 months, 1,640 at 3.5 months, and

2,258 at 4.5 months. All the matching

procedures excluded subjects with

birthweights <1,500 grams.

Head circumference at birth was not

available from the national surveys or

from birth certificates. Consequently, the

head circumference-for-age curves

included data for head circumference at

birth from 362 infants in the Fels

Longitudinal Study who were born

between the years 1960 and 1994,

corresponding to the national surveys.

Most of these data were recorded in

hospitals by the Fels staff. The Fels

Longitudinal Study began in 1929 with

a major goal of following physical

growth and development in a cohort of

1,000 people from birth throughout their

entire life cycle (32). Data at birth,

including head circumference at birth,

obtained since 1975, come from

relatives of the early cohorts.

Data Exclusions

Several exclusions were made prior

to curve smoothing. First, data for all

very low birthweight (VLBW) infants

(<1,500 grams) were excluded from the

infant growth charts, primarily because

the growth of VLBW infants is known

to be markedly different from that of

higher birthweight, full-term infants. For

NHANES I and II, if a reported

birthweight from the interview

questionnaire was not available, an

exclusion was not applied. As part of

the NHANES III protocol, birth

certificates were obtained from the

States for children born in the United

States. For NHANES III, if a reported

birthweight was missing from the survey

interview data, birthweight from the

child’s birth certificate was used to

determine possible exclusion, and, if

neither were available, an exclusion was

not made. Second, data from NHANES

III for children greater than or equal to

6 years of age were excluded from the

charts for weight-for-age, weight-forstature, and BMI-for-age. Inclusion of

these data would have led to the

underclassification of overweight,

because overweight cutoff criteria based

on weight- and BMI-for-age percentiles

would have been shifted upward. Third,

11 infants whose recumbent length and

stature differed by greater than or equal

to 5 cm were excluded from the

length-for-age, weight-for-length,

stature-for-age, weight-for-stature, and

BMI-for-age charts. Fourth, two outlier

values, one for head circumference of an

infant girl, and one for recumbent length

of an infant boy, were excluded because

the measurement values and the

sampling weights were extreme.

Statistical Curve

Smoothing Procedures

Data from the national surveys were

pooled because no single survey in the

NHANES series has enough

observations to construct growth charts.

Sample sizes from 400 to 500 are

required to achieve precision of the

empirical percentiles at the specific ages

selected for the curve fitting (33). This

is particularly important for outlying

percentiles that are used in research and

clinical practice. Pooling enhances the

number of subjects at each age, thereby

increasing the stability of the outlying

percentile estimates.

Statistical sample weights were

available for each national survey. These

sample weights take into account the

unequal probabilities of selection

resulting from the complex sampling

cluster design, planned oversampling of

selected subgroups, nonresponse, and

noncoverage. These survey-specific

sample weights were applied to the

national survey data resulting in each

survey representing the U.S. population

at the time the survey was conducted.

All statistics were calculated with the

original survey sample weights.

Sampling weights were not available for

the supplemental data.

Statistical procedures were applied

to the observed data in two stages, first

to generate initial smoothed curves for

selected major percentiles and second to

generate the parameters that were used

to construct the final smoothed curves

and additional percentiles. The first

stage is referred to as the curve

smoothing stage, and the second stage

as the transformation stage. In the first

stage, selected empirical percentiles

were smoothed with a variety of

parametric and nonparametric regression

procedures. In the transformation stage,

the smoothed curves were approximated

using a modified LMS estimation

procedure to provide the transformation

parameters, lambda, mu, and sigma

(LMS). This resulted in final percentile

curves that closely matched the

percentile curves smoothed in the first

stage and allowed computation of

additional percentiles and z-scores. The

procedures for each stage are described

Table D. Summary of curve smoothing procedures

Curve Curve smoothing procedures

Weight-for-age For birth to 36 months, a 3-parameter linear model fit to empirical percentile points for weight at midpoints of age intervals, and

anchored (i.e., forced) at birth and at 2.75 years. Averages of weighted empirical percentiles at 2.25 and 2.75 years (based on data

used for birth to 36 months and 2 to 20 years) substituted for data points in the 24 to 36 months range.

For 2 to 20 years, locally weighted regression (LWR) based on 15-point smoothing for boys and 17-point smoothing for girls. Fit to

empirical percentile points for weight at midpoints of age intervals, combined averages of weighted empirical percentiles at 2.25 and

2.75 years (based on data used for birth to 36 months and 2 to 20 years), and predicted values for 2 to 3 years at 0.1 year intervals

from the 3-parameter linear model used for birth to 36 months.

All results from the 3-parameter linear model and LWR were combined and refit at midpoints of age intervals from birth to 20 years

using a 10-parameter polynomial regression model for boys and 9-parameter polynomial regression model for girls.

Length-for-age and

Stature-for-age

For length-for-age, birth to 36 months, a 3-parameter linear model was fit to empirical percentile points for length at midpoints of age

intervals and to birth data.

For stature-for-age, 2 to 20 years, a 10-parameter nonlinear model was fit to empirical points for stature at midpoints of age intervals.

Results from the 3-parameter linear model used for length-for-age were adjusted by subtracting 0.8 cm from length to make length

continuous with stature in the overlapping age interval of 24 to 36 months. Percentiles in the overlap period were averaged by

assigning weights of 1, 11/12, ..., 1/12, 0 at 24, 25, ..., 35, 36 months, respectively, to the adjusted length-for-age. Opposite weights

of 0, 1/12, ..., 11/12, 12/12 at 24, 25, ..., 35, 36 months, respectively, were assigned to smoothed stature-for-age percentiles. The

final length-for-age and stature-for-age curves were created by adding back 0.8 cm to the smoothed length.

Head circumference-forageFor birth to 36 months, a 3-parameter linear model was fit to empirical percentile points for head circumference at midpoints of age

intervals and to birth data.

Weight-for-length and

Weight-for-stature

Empirical weight-for-length data were adjusted by subtracting 0.8 cm from length to make length continuous with stature in the

overlapping age interval of 24 to 36 months. The combined adjusted weight-for-length and weight-for-stature data were smoothed

with a 5-parameter polynomial regression model, fit to empirical percentile points for weight at midpoints of 2 cm intervals. After

applying LMS, separate weight-for-length curves were created by adding 0.8 cm back to length.

BMI-for-age For 2 to 20 years, LWR model was based on a 5-point smoothing at midpoints of age intervals for ages 2 to 12.5 years, and a

25-point smoothing for boys and a 27-point smoothing for girls for ages 13 to 20 years. The curves were further smoothed with a

4-parameter polynomial regression model fit to smoothed percentile points for BMI at midpoints of age intervals.

in detail for each chart and are

summarized in table D.

Age and Length Groupings

Before smoothing, data were grouped

by single month of age for the

development of charts relating size to age.

Each month of age was truncated to the

nearest completed month, for example, 1

month (1.0–1.9 months), 11 months

(11.0–11.9 months), 23 months (23.0–23.9

months), and so forth. From birth to 12

months, the empirical percentile

estimates were made at 1-month

intervals; from 12 to 24 months, the

empirical percentile estimates were

made at 3-month intervals; and at 24

months and beyond, empirical percentile

estimates were made at 6-month

intervals. All ages were labeled as the

midpoint of the defined age groups. For

the infant charts, infants were grouped

as follows: 0.5 months = 0.1–0.9

months (birth was not included),

1.5 months = 1.0–1.9 months, ...,

11.5 months = 11.0–11.9 months;

13.5 months = 12.0–14.9 months,

16.5 months = 15.0–17.9 months,

19.5 months = 18.0–20.9 months,

22.5 months = 21.0–23.9 months;

27.0 months = 24.0–29.9 months, and

33.0 months = 30.0–35.9 months.

For the charts for older children and

adolescents, subjects were separated into

36 half-year age groups. Each age group

was categorized by the midpoint of an

age range. For example, age 2.25 years

included ages from 2.0 years to 2.5

years of age. This pattern continued up

to the 19.75 year age interval in which

the age range is from 19.5 to 20.0 years

of age.

Before smoothing, the length and

stature data were grouped by 2-cm

intervals. For example, 46 cm =

45–46.9 cm.

Curve Smoothing Stage

For each growth chart, the initial

smoothing methods were applied to nine

empirical percentiles (3rd, 5th, 10th,

25th, 50th, 75th, 90th, 95th, and 97th).

In addition, the 85th percentile was

included in the BMI-for-age charts

because the 85th percentile of BMI has

been recommended as a cutoff to

identify children and adolescents at risk

for overweight (34,35).

The weighted empirical percentile

estimates were obtained by applying the

survey-specific sample weights to

calculate weighted empirical percentile

points at the midpoint of each age group

(or the midpoint of each 2-cm interval

for length or stature). The irregular plots

of empirical percentile values had to be

smoothed to produce clinically useful

percentile curves.

Several different approaches were

used in the smoothing stage. The

empirical percentiles for infant weight,

length, and head circumference were

smoothed using a family of threeparameter linear models that have been

used previously to describe age-related

changes in growth from birth to age 36

months (36–38). Stature-for-age was

smoothed using a nonlinear model

whereas weight-for-stature and

weight-for-length were smoothed using

a 5-degree polynomial regression model.

Two-step smoothing was applied to

weight-for-age in infants and older

children and BMI-for-age. In the first

step of smoothing weight-for-age and

BMI-for-age for older children, locally

weighted regression (LWR) was used.

Polynomial regression was used in the

second step of smoothing weight-for-age

and BMI-for-age. The smoothing stage

resulted in every chart having a
Series 11, No. 246 [ Page 7

parametric form with estimated

parameters specific for each selected

major percentile.

The parameters of the linear

regressions were estimated using the

SAS procedure REG, and the parameters

in the nonlinear regression were

estimated using the SAS procedure

NLIN (39). The fit of the models was

evaluated using root mean square error

(RMSE), R2

, and CV (40).

The Transformation Stage

In order to estimate any percentile

and allow calculation of standard

deviation units and z-scores, a modified

LMS statistical procedure was applied to

the smoothed percentile curves. The

LMS method does not change the

distribution of percentile curves in a

growth chart; rather it provides a way to

estimate percentiles in a continuous

manner.

The distribution of some

anthropometric data used in the growth

charts are skewed. To remove skewness,

a power transformation can be used to

stretch one tail of the distribution while

the other tail is shrunk. A Box-Cox

transformation can make the distribution

nearly normal (41). The assumption is

that, after the appropriate power

transformation, the data are closely

approximated by a normal

distribution (42). The transformation

does not adjust for kurtosis, which is a

less important contributor to

nonnormality than skewness (43).

In the LMS technique, three

parameters are estimated: the median

(M), the generalized coefficient of

variation (S), and the power in the

Box-Cox transformation (L). The L

reflects the degree of skewness. The

LMS transformation equation is:

X = M (1 + LSZ)

1/L L ≠ 0

or

X = M exp(SZ) L = 0

where X is the physical measurement

and Z is the z-score that corresponds to

the percentile.

The key task of the transformation

was to estimate parameters L, M, and S.

With estimates of L, M, and S, values of

X are connected to the values of Z

through the above equation. The

percentile is obtained from a normal

distribution table where the z-score

corresponds to the percentile of interest.

For example, a z-score of 0.2019

corresponds to the 58th percentile. In

the case of growth charts, with the L, M,

and S parameters, it is possible to

evaluate any single measure in a

population as an exact z-score or

percentile.

To generate age-specific estimates

of L, M, and S, Cole (42,44) has

recommended applying a penalized

likelihood estimation procedure to the

raw data. In this approach smoothed

curves of L, M, and S are generated

first, and then smoothed percentile

curves, or an individual standardized

score, can be obtained from the values

of L, M, and S.

In contrast to the original LMS

procedure, a modified LMS estimation

procedure was created and used to

generate the 2000 CDC Growth Charts.

In the modified LMS approach,

empirical percentile curves were initially

smoothed and parametric models were

generated, as described above. Then, at

each age or length/stature interval, a

group of 9 equations (10 for BMI

charts) was generated by specifying the

LMS transformation equations for the

previously smoothed major percentiles.

A simultaneous solution for the three

parameters of L, M, and S from the

group of specified equations was

generated using the SAS procedure

NLIN (39). By minimizing the sum of

squared errors, the set of L, M, and S

parameters was obtained as the best

solution to a system of equations rather

than as likelihood-based estimates from

empirical data. This approach is similar

to the method used by Cole to estimate

LMS parameters from published

percentile curves (45–47).

This modified LMS procedure

produced final curves that are extremely

close to the smoothed percentile curves

obtained from the first stage of

smoothing. The net result is that the

close fit of the smoothed curves from

the first stage of smoothing to the

empirical data is retained. In addition,

the modified LMS method allows

z-scores to be obtained in a continuous

manner. The LMS values were

calculated by solving equations that

used the values for percentiles ranging

from the 3rd to the 97th. Percentiles less

than the 3rd or greater than the 97th are

beyond the range of the data from

which the LMS parameters were

calculated. As in any statistical

procedure, extrapolation beyond the

range of the data should be done with

caution.

The final set of percentile curves

for the CDC growth charts presented in

this report was produced using this

modified LMS estimation procedure. In

the transformation stage, percentiles

were developed at 1-month or

1-centimeter intervals in the infant and

child charts. Estimates of L, M, and S

parameters in these intervals were

calculated to provide the necessary tools

for determining additional percentiles.

Generally, 1-month or 1-centimeter

intervals will be adequate for estimation

or evaluation. To obtain percentiles at

finer intervals, the L, M, and S values

could be interpolated.

Detailed Procedures by Chart

Weight-for-Age

Combining infant and child/adolescent

weight-for-age—After the infant

weight-for-age and child/adolescent

weight-for-age curves were smoothed

using a 3-parameter linear model and

LWR, the results were combined and

refit from birth to age 20 years using a

single regression model for each sex.

The smoothed weight-for-age curves for

infants and for older children were

combined to obtain a seamless transition

between the curves. Ultimately the

combined weight-for-age curve was

separated into infant and child/

adolescent curves to facilitate use in

clinical settings.

In order to combine the infant and

child/adolescent weight-for-age curves,

weighted averages of overlapping

empirical percentiles from infant and

child charts at 2.25 years (24.0–29.9

months) and 2.75 years (30.0–35.9

months) were calculated using the

combined infant and child/adolescent

data. The empirical percentiles were not

identical at ages 24–36.9 months

because VLBW infants (<1,500 grams)

were excluded from the infant
percentiles, but included in the older

child percentiles where the effect of

VLBW is diminished. The averaged

percentiles were substituted for the

empirical values in smoothing the

weight-for-age for infants and

weight-for-age for children/adolescents.

These combined percentile curves were

fit by a 10-degree polynomial for boys

and by a 9-degree polynomial for girls.

A set of nine polynomial regression

equations, one for each of the major

smoothed percentiles, was solved

simultaneously for infants and for

children to estimate the L, M, and S

parameters for boys and for girls

separately.

Weight-for-age, birth to 36 months—

The infant weight-for-age curves for

ages birth to 36 months were smoothed

initially with a 3-parameter linear

model:

f(t) = a+b * ln(t+0.5) + c(t+0.5)0.75

where f(t) is body weight in kg, t is age

in months (calculated as midpoint of the

age range), and a, b, and c are

parameters to be estimated. The

estimated values of f(t) are the smoothed

values. At birth, t = 0. Estimates of a, b,

and c are specific for each of nine

percentiles being smoothed. An

exponent of 0.75 was selected based on

the evaluation of RMSE after several

models were tried, beginning with the

exponent of 0.3.

After excluding birthweights

<1,500 gm, the model was fit to the

national data with anchor points at birth

and at 2.75 years. In other words, when

the regression line was fit, no error term

was allowed at the two anchor points.

The curves were anchored to the

national distribution of birthweights

(years 1968–80 and 1985–94) from

NCHS natality files (that is, forced

through the sex-specific summary values

provided for the major centile lines at

birth) after excluding birthweights

<1,500 gm, and forced through the

weighted average percentile values at

2.75 years.

Weight-for-age, 2 to 20 years—Initial

smoothing of weight-for-age for older

children involved combining the

weighted average of the empirical

percentiles for infants and older children

at 2.25 and 2.75 years, predicted infant

values for weight from 2 to 3 years at

0.1-year intervals from the 3-parameter

linear model and the empirical

percentiles from 3 to 20 years. This

approach used all available information

for infants after excluding data for

VLBW infants and for older children

where data for VLBW infants were not

excluded. Some empirical data less than

2 years of age and greater than or equal

to 20 years were included, as described

below. This compound data set was

smoothed with a locally weighted

regression (LWR) procedure.

The LWR does not give any

parameter estimates, but provides an

intermediate smoothed curve for further

parametric smoothing. Locally weighted

regression applies a weight function to

data in the neighborhood of the value to

be estimated (48). Ages at measurements

that are near that of the value to be

estimated received larger weights than

those farther away from the specific age.

A weight function

? ? X0 – Xi 3

)

3

Weight = (1– ΔX

applies larger weights to data points

near the value to be estimated than to

those further away, where X0 is the

central age at which the value is

smoothed, Xi is the ith age from the

central age and the value to which the

weight is being assigned, and ΔX is the

age range covered by the width of the

moving regression window. The

mechanics of LWR require the selection

of a series of points on either side of the

value to be estimated. This series of

points constitutes the regression window.

Windows for each of the values to be

estimated overlap and are referred to as

moving regression windows. The

weighted least squares regression is

applied to the values in each moving

regression window to provide the

smoothed estimate at X0. The resulting

estimates from each regression window

form a smoothed curve.

The width of the LWR moving

window for weight-for-age was chosen

after several trials to balance the degree

of smoothness and fidelity to the data.

For boys, each smoothed value was

estimated by a weighted linear

Page 8 [ Series 11, No. 246

regression on the 15 neighborhood

points adjacent to the estimated value.

For girls, a 17-point smoothing

procedure was chosen. Seven data points

for boys and eight data points for girls

at ages less than 2 years were necessary

for smoothing the value at age 2 years.

The weight value at age 1.75 years in

boys was repeated 7 times from age

1.75 down to 1.15 years by 0.1-year

intervals, and in girls was repeated 8

times from age 1.75 down to 1.05 years

by 0.1-year intervals. Similarly, when

smoothing the value at age 20 years,

seven and eight data points at ages over

20 years were necessary for boys and

girls, respectively. For boys, the

empirical percentiles from 20.25 to

23.25 years by 0.5-year intervals were

used as seven additional data points for

smoothing. For girls, the empirical

percentiles after age 18 years were very

irregular due to the limited number of

subjects and considerable variation in

body weight. Therefore, instead of using

empirical percentiles from 20 to 25

years, the value at age 20.25 years was

repeated 8 times from age 20.25 to

23.75 years by 0.5-year intervals to

achieve reasonably smoothed values

near age 20 years.

Length-for-Age and Stature-for-Age

Combining length-for-age and

stature-for-age—A smooth transition

from the length-for-age to stature-forage chart was required. Analyses of data

from NHANES II and III children

indicated that recumbent length is, on

average, 0.8 cm longer than standing

height (stature). Thus, it is desirable to

have parallel smoothed percentile curves

for length-for-age and stature-for-age

with a difference of 0.8 cm between

length and stature in the overlapping

ages from 24 to 36 months.

To obtain these parallel curves,

percentiles for each month of age were

predicted by the 3-parameter model in

the length-for-age portion and by the

10-parameter nonlinear model in the

stature-for-age portion. Length-for-age

percentiles were adjusted by subtracting

0.8 cm from length to make length

commensurate with stature. Averages of

the percentiles in the two charts in the

overlapping ages were calculated by

assigning weights of 1, 11/12, 10/12, ...,
Series 11, No. 246 [ Page 9

1/12, 0 to values of length-for-age at 24,

25, 26, ..., 35, 36 months, respectively,

and assigning opposite weights of 0, 1/12,

..., 11/12, 1 to values of stature-for-age at

24, 25, ..., 35, 36 months, respectively.

These weighted average percentile values

in the overlapping section were shared by

both charts. Length-for-age was readjusted

by adding back 0.8 cm to length,

producing separate length-for-age and

stature-for-age curves. This resulted in the

two sets of parallel percentiles with a

consistent separation of 0.8 cm in the

overlapping section.

Two sets of nine equations (one set

for length-for-age and one set for

stature-for-age), for each of the major

smoothed percentiles, were solved

simultaneously to estimate the L, M, and

S parameters for boys and girls

separately. The nine final percentile

curves for infants and children were

predicted using the estimated L, M, and

S values.

Length-for-age, birth to 36 months—The

infant recumbent length-for-age curves for

ages birth to 36 months were smoothed

with a 3-parameter linear model:

f(t) = a+b * ln (t+1) + c(t+1)0.5

where f(t) is length in cm, t is age in

months (calculated as midpoint of the

age range), and a, b, and c are

parameters to be estimated. The

estimated values of f(t) are the smoothed

values. At birth, t = 0. Estimates of a, b,

and c are specific for each of nine

percentiles being smoothed.

After excluding birthweights

<1,500 gm, the 3-parameter model was

fit to the national data and birth length

distributions from Wisconsin and

Missouri. In contrast to data from the

NCHS surveys that were pooled prior to

curve smoothing, the Wisconsin and

Missouri data were not pooled, but were

treated as two separate sets of data

points in the curve smoothing. Because

the fitted values did not match other

data sets well in the first few months of

life, and because the smoothed point at

2.5 months was unstable due to

insufficient sample size, data from a

subset of the PedNSS at ages 0.5, 1.5,

and 2.5 months were also included.

Inclusion of these additional data at

younger ages provided a better fit of the

3-parameter model in the first several

months of age. To gradually merge the

PedNSS data with the national survey

data, PedNSS data were averaged with

the national data at ages 3.5 and 4.5

months, after which the national data

were used exclusively.

Stature-for-age—The stature-for-age

curves for ages from 2 to 20 years were

smoothed with a nonlinear model that

ensured a monotonic increase in stature:

–b2(t–c2 f(t) = aq/(1+e ) –b1(t–c1)) + ap/(1+e

–b3(t–c3) + (f–a) / (1+e )

where f(t) is stature in cm, t is age in

years (calculated as midpoint of the age

range), and a, b1, b2, b3, c1, c2, c3, p, q,

and f are parameters to be estimated

(p = 1–q). The estimated values of f(t)

are the smoothed values. Estimates of a,

b1, b2, b3, c1, c2, c3, p, q, and f are

specific for each of nine percentiles

being smoothed.

The empirical percentile curves

derived from the national survey data

were irregular partly due to sampling

variations and the small number of

subjects older than 18 years. To aid in

smoothing the irregular empirical

percentile curves at older ages, the

empirical data were extended to age 25

years in 0.5-year intervals. For girls,

empirical data for the 6-month age

group from 1.5 to 2.0 years (midpoint

1.75) were also included to provide

smoothed estimates closer to the

empirical percentiles than the estimates

obtained without inclusion of such data.

Unadjusted recumbent length data were

used as a proxy for stature in the age

group from 1.5 to 2.0 years.

Head Circumference-for-Age

The infant head circumference-forage curves for ages birth to 36 months

were smoothed with a 3-parameter

linear model:

f(t) = a+b * ln (t+2) + c (t+2)0.5

where f(t) is head circumference in cm, t

is age in months (calculated as midpoint

of the age range), and a, b, and c are

parameters to be estimated. The

estimated values of f(t) are the smoothed

values. At birth, t = 0. Estimates of a, b,

and c are specific for each of nine

percentiles being smoothed. After

excluding birthweight <1,500 gm, the

model was fit to the national data and

head circumference at birth from the

Fels Longitudinal Study.

A set of nine 3-parameter linear

equations, one for each of the major

smoothed percentiles, was solved

simultaneously to estimate the L, M, and

S parameters for boys and girls

separately. The nine final percentile

curves for infants were predicted using

the estimated L, M, and S values.

Weight-for-Length and Weight-forStature

Similar to length-for-age and

stature-for-age, weight-for-length and

weight-for-stature required a smooth

transition. Consequently weight-forlength and weight-for-stature were

developed together using a single

regression model. Before fitting the

model to the data, 0.8 cm was

subtracted from each empirical

recumbent length data point. The shifted

empirical weight-for-length data were

smoothed simultaneously with the

empirical weight-for-stature data using a

5-degree polynomial regression model.

The 5-degree polynomial regression

model was fit to the national data and to

weight-for-length data at birth from

Wisconsin and Missouri. The birth

length intervals from Wisconsin and

Missouri began at 45 cm. However,

there was a discontinuity between the

State data and the national data perhaps

due to lack of data between birth and 2

months. To avoid lowering the estimates

for weight-for-length, data from 53 to

65 cm from the State or national data

were omitted in the smoothing

procedure.

The weight-for-length and

weight-for-stature charts are age

independent. Empirical percentiles of

weight were based on recumbent length

or stature in 2-cm intervals. Although

the weight-for-length chart was

developed for use with infants from

birth to 36 months, and weight-forstature was developed primarily for use

with children from 24 to 60 months of

age to maximize sample sizes, an upper

age limit was not used in the

development of either chart. Available

weight-for-length data ranged from 45
Page 10 [ Series 11, No. 246

to 109 cm and available weight-forstature data ranged from 77 to 127 cm

for calculating empirical percentiles.

After the final curve smoothing,

weight-for-length was truncated to

103 cm and weight-for-stature was

truncated to 121 cm on the final charts.

A set of nine 5-degree polynomial

regression equations, one for each of the

major smoothed percentiles for the

combined weight-for-length and

weight-for-stature data, was solved

simultaneously to estimate the L, M, and

S parameters for boys and girls

separately. The nine final percentile

curves for infants were predicted using

the estimated L, M, and S values. To

obtain separate weight-for-length and

weight-for-stature curves, 0.8 cm was

added back to all the smoothed length

values. This was accomplished by

shifting back the corresponding length

values for the length-specific weight, L,

M, and S, by 0.8 cm to form the

weight-for-length measure from the

weight-for-stature scale. The 85th

percentile of weight-for-stature was

calculated subsequently from the L, M,

and S values.

Body Mass Index-for-Age

Empirical percentiles from the

national data were smoothed with LWR.

Ten empirical percentiles were

calculated for the BMI-for-age charts

because the additional 85th percentile

was required for boys and girls to

identify children and adolescents at risk

for overweight. Each smoothed value

was estimated by weighted linear

regression on the five-neighborhood

points adjacent to the value to be

estimated from ages 2 to 12.5 years.

From 13 to 20 years, a 25-point

smoothing procedure was used for boys

and a 27-point smoothing procedure was

used for girls. At the lower end (that is,

age 2 years), two additional points were

needed in the smoothing window, so a

neighborhood point of 1.75 years was

used for BMI. This was calculated using

unadjusted recumbent length, repeated at

1.75 and at 1.71 years for both sexes. At

the upper end (that is, age 20 years), the

maximum BMI values in each empirical

percentile from age 19.75 through 25.25

years were chosen and repeated in

0.5-year intervals from 20.25 through

25.75 years for boys or from 20.25

through 26.25 years for girls. Taking

maximum values as additional data in

smoothing the windows ensured that the

BMI curves did not increase beyond the

maxima at the upper ends of the age

ranges. The smoothed percentile curves

obtained through LWR were then fit by

a 4-degree polynomial regression to

achieve parametric percentiles. (See

section on weight-for-age, 2 to 20 years,

above, for further description of LWR.)

A set of 10, 4-degree polynomial

regression equations, 1 for each of the

major smoothed percentiles, was solved

simultaneously to estimate the L, M, and

S parameters for boys and girls

separately. The 10 final percentile

curves for infants were predicted using

the estimated L, M, and S values.

Results

Observed and Smoothed

Percentiles

The observed percentile distributions,

along with means and standard deviations,

are shown by sex and age in detailed

tables 9–16. Selected smoothed percentiles

(3rd, 5th, 10th, 25th, 50th, 75th, 90th,

95th, and 97th for all charts, and 85th for

BMI-for-age and weight-for-stature) are

shown in detailed tables 17–24 for the 16

age- and sex-specific growth charts. Also

presented in these tables are the L, M, and

S parameters that were used to create the

final charts and are needed to generate

additional percentiles and z-scores.

The smoothed 3rd, 5th, 10th, 25th,

50th, 75th, 90th, 95th, and 97th

percentile curves that constitute the 16

individual CDC growth charts for the

United States are shown in figures 1–16.

In addition, the 85th percentile is shown

in figures 13 and 14 for BMI-for-age

and in figures 15 and 16 for weight-forstature. Two additional sets of individual

charts not shown in this report are

available on the Internet (www.cdc.gov/

growthcharts). One set shows curves

ranging from the 5th to 95th percentiles

(without the 3rd and 97th), and another

set has the 3rd to 97th percentiles

(without the 5th and 95th).

The growth charts shown in

figures 1–14 have a primary scale in

English units (lb, in), and a secondary

scale in metric units (kg, cm), except in

the BMI-for-age charts where there are

single scales (kg/m2

) as shown in

figures 15 and 16.

Figures 17–26 show the charts

developed for clinical use depicting the

5th, 10th, 25th, 50th, 75th, 90th, and

95th percentiles, and 85th for

BMI-for-age and weight-for-stature. This

format has two charts per page and

includes tables for recording

measurement data. For the clinical

charts, the primary scale is metric and

the secondary scale is English. A

comparable set of clinical charts with

the 3rd and 97th percentiles in place of

the 5th and 95th not shown in this

report is available on the Internet

(www.cdc.gov/growthcharts).

Evaluation of the Revised

Growth Curves

After the initial smoothing and

transformation stages were completed,

the percentile curves were evaluated.

Transitions between the infant and older

child charts were reviewed and each

major percentile curve (3rd, 5th, 10th,

25th, 50th, 75th, 90th, 95th, 97th, and

85th for BMI-for-age) was compared

graphically with the corresponding

empirical data. In addition, the percent

of empirical data below the smoothed

percentiles was calculated and compared

with the expected values. The objective

of these procedures was to search for

any large or systematic differences

between the smoothed percentiles and

the empirical data.

Evaluation of the transitions

between the charts from birth to 36

months to the charts from 2 to 20 years

indicated that disjunctions that were

present in the 1977 NCHS charts were

not present in the 2000 CDC charts. The

final charts for length-for-age and

stature-for-age were constructed

simultaneously with an imposed parallel

separation of 0.8 cm, based on the

average difference between measured

length and stature. Consequently, the

smoothed percentile curves for

length-for-age and stature-for-age are
Series 11, No. 246 [ Page 11

parallel to each other as shown in

figures 27–28. A child should have

similar values for length-for-age or

stature-for-age. Weight-for-length and

weight-for-stature were constructed with

an imposed offset of 0.8 cm (figures 29

and 30).

The results of graphical

comparisons for evaluation of the final

curves are shown in figures 31–62.

Overall, the smoothed curves fit the

empirical data well, without any

systematic departures. This was

particularly true for stature-for-age

(figures 55–58). Nevertheless, for all the

curves, the empirical data points at the

outer percentiles tended to be more

irregular relative to those at the more

central percentiles.

Although the performance of the

final smoothed curves was judged

acceptable, the weight-for-age curves

diverged from the empirical data points

at some ages, even at the median, where

estimates generally are expected to be

most stable. This divergence was

particularly evident from 3 to 11 months

(figures 31–34) and after approximately

12 or 13 years (144–156 months in

figures 53–54). For BMI-for-age

(figures 59–62), the empirical data,

especially for values greater than or

equal to the 75th percentile and during

the adolescent years, showed a high

degree of variability around the

smoothed percentile lines.

The observed and the expected

percents below the smoothed percentiles

are shown graphically in figures 63–94.

Approximately 50 percent of the

observed data would be expected to fall

below the smoothed median or 50th

percentile. The findings indicated

acceptable results for the percent of

empirical data below the smoothed

curves.

Differences Between the

1977 NCHS and the 2000

CDC Growth Curves

The smoothed 1977 and 2000

percentile curves were compared

graphically as shown in figures 95–108.

The comparisons are limited to the

charts, ages, and percentile lines

common to both sets of references.

Thus, comparisons were not possible for

the new BMI-for-age charts, for the

weight-for-stature charts above 120 cm

of stature, for ages over 17 years on any

chart, or for the 3rd and 97th percentiles

on any chart.

Overall, the 1977 and the 2000

growth curves are quite similar. The

differences that exist are more apparent

in charts for infants where national

survey data were previously lacking

than in the charts for older children. For

infants, the major differences were seen

in the head circumference-for-age charts.

In the other infant charts, differences

generally occurred at the outer (lower

and upper) percentiles. For older

children, there were almost no

differences in the stature-for-age charts

and only minor differences in the

weight-for-age charts.

Infant Charts

From approximately 12 to 24

months for infant weight-for-age, the

2000 percentiles are generally higher

than the corresponding 1977 percentiles.

This is most evident at the 5th and 10th

percentiles (figures 95–96). The 2000

length-for-age curves are generally

lower than the 1977 curves, especially

after 6 months of age when the 2000

10th percentile approximates the 1977

5th percentile (figures 97 and 98). In the

weight-for-length curves (figures 99 and

100), for lengths ranging from

approximately 50 to 70 cm, the 2000

curves are higher than the 1977 curves.

This is most evident at lower

percentiles, where the 5th percentile for

the 2000 charts is equivalent to the 25th

percentile in the 1977 charts. The dip

that occurred in the 1977, 5th and 10th

percentiles at the 50–70 cm range is

absent from the 2000 weight-for-length

charts. Comparisons of the head

circumference-for-age percentiles

indicate considerable differences

(figures 101 and 102). Generally, the

2000 smoothed percentiles are higher

than the 1977 percentiles from birth

until approximately 4–6 months, where

a crossover occurs and the 2000 curves

become lower than the 1977 curves

(figures 101 and 102).

When the 2000 charts are used

there will be some differences in clinical

classifications relative to the 1977

charts. For example, with the 2000

charts, infants will be more often

classified as underweight, less often

classified as high weight-for-age, less

often classified as having short

length-for-age, less often classified as

having small head circumference

particularly after 6 months, and more

often classified as having large head

circumference.

Child/Adolescent Charts

Comparisons of the weight-forstature charts are limited because the

range of statures differed in the 2000

charts compared with the 1977 charts.

For matching statures within the range

shown, weights in the 2000 charts tend

to be higher than weights in the 1977

charts, especially at larger statures and

for girls (figures 103 and 104). Overall,

from approximately 2 to 14 years, the

1977 and 2000 weight-for-age curves

are similar. Even though the 1977 and

2000 data sets for weight-for-age closely

match after 6 years, differences in the

percentile curves beyond age 14 years

(168 months) may reflect limitations of

the curve smoothing procedures in the

1977 weight-for-age charts (figures 105

and 106). The 1977 and 2000 charts for

stature-for-age are quite similar

(figures 107 and 108).

Discussion

Revision Process

The 1977 NCHS Growth Charts

have been widely used in pediatric

practice and public health for more than

20 years. Although some concerns about

these growth charts arose, the charts had

not undergone a major formal revision

since they were developed. There was,

however, an interim adjustment to the

length-for-age and stature-for-age, and

weight-for-length and weight-for-stature

curves, designed for use in limited

applications for the analysis of

population-based survey and

surveillance data (22,49). In 1985, when

planning the sample design for

NHANES III, NCHS began the growth
Page 12 [ Series 11, No. 246

chart revision process with the decision

to oversample infants and young

children for the purpose of revising the

1977 growth charts.

Growth Chart Workshops

Beginning in December 1992

NCHS sponsored a series of workshops

to obtain expert input for revising the

1977 NCHS Growth Charts. These

workshops were intended to provide

options and recommendations that

would be considered in making final

decisions on how best to proceed. The

participants and highlights of the

workshops are presented in appendix I.

Three of these workshops were

summarized in reports that are

available on the Internet

(www.cdc.gov/growthcharts). The

workshop reports include appendixes

with supporting data and references.

Major Features of the 2000

CDC Growth Charts for

the United States

The 2000 CDC Growth Charts for

the United States differ from the 1977

NCHS Growth Charts with regard to data

and methods used in their construction. In

addition, there are a number of new

features in the 2000 charts that were not

previously available:

+	 National survey data

In the 2000 CDC charts, nationally

representative survey data,

supplemented with a limited amount

of data from other sources, replaced

the Fels data used in the 1977

NCHS infant growth charts from

birth to 36 months.

+	 Body mass index-for-age charts

New sex-specific BMI-for-age

charts for 2 to 20 years were

developed to replace the 1977

NCHS weight-for-stature charts

that were applicable only at

prepubescent ages for statures for

boys ranging from 90 to 145 cm

and for girls ranging from 90 to

137 cm. Revised weight-for-stature

charts are available for optional

use from ages 2 to 5 years. Either

BMI-for-age or weight-for-stature

charts may be used to assess risk

of overweight from ages 2 to 5

years.

+	 Extended age range

The revised charts were extended by

2 years beyond the 1977 NCHS

charts to include children and

adolescents from 2 to 20 years of

age. This change was made to

accommodate adolescents who

continue to be seen by pediatricians

through their later teenage years.

+	 Additional percentiles

The 3rd and 97th percentiles were

added to each chart to facilitate

plotting data for children at

extremes of the distribution. The

major percentiles included in the

1977 NCHS charts (5th, 10th, 25th,

50th, 75th, 90th, and 95th) were

retained in the revised charts. The

85th percentile was added to

weight-for-stature and BMI-for-age

charts, enhancing their use as

screening tools to identify children

and adolescents who may be

overweight or at risk of overweight.

+	 Corresponding percentiles and

z-scores

The 2000 CDC Growth Charts can

be used to obtain percentiles and

z-scores. To meet the needs of

researchers, for analyses of

surveillance data, and to monitor

changes in growth indicators for

individuals, z-scores can be obtained

and exact percentiles can be

calculated.

+	 Smooth junction between length

and stature

The revised charts largely correct

discontinuities that existed in the

1977 charts for infants and older

children from 24 to 36 months.

These disjunctions were the result of

using data from different sources.

Using the Revised Growth

Charts

Screening for Health and

Nutritional Status

The 5th and 95th percentiles of the

1977 NCHS Growth Charts have been

used for many years as screening

indicators, particularly for infants. These

percentile cutoff values are used to help

identify infants and children who are at

increased nutritional and overall health

risk.

Where there are differences between

the 2000 and the 1977 curves, the

percentile ranking of a child may differ.

In general, when the upper percentiles

of the revised curves are higher than the

corresponding percentiles of the 1977

curves, this will result in less frequent

classification as high risk. When the

lower percentiles of the revised curves

are higher than the corresponding

percentiles of the 1977 curves,

classification as high risk will be more

frequent. For example, the 90th and

95th infant weight-for-age percentiles of

the revised curves are higher than the

corresponding percentiles of the 1977

curves from approximately 6 to 36

months for boys, and from 12 to 36

months for girls. This shift would be

expected to result in lower estimates for

the prevalence of overweight when

using the revised charts. In contrast,

after approximately 6 months, all

percentiles in the revised head

circumference charts are lower than the

corresponding percentiles in the 1977

charts. The expected impact for clinical

screening or for population-based

prevalence estimates, using the 2000

charts compared with the 1977 charts, is

that children may be classified less

frequently as having small head

circumferences and may be more

frequently classified as having large

head circumferences. Other examples

are evident in the detailed figures in this

report that compare the 2000 percentile

curves with the 1977 percentile curves.

Racial-Ethnic Considerations

Children of all major racial-ethnic

groups appear to have similar growth

potential. Studies have demonstrated

that genetic effects on growth are small

compared with the effects of the

environment, nutrition, and health.

Regardless of racial-ethnic status,

children provided with good nutrition,

access to health care, and good social

and general living conditions have

similar growth patterns (13,50–55).
Series 11, No. 246 [ Page 13

The 2000 growth charts were

produced for all children in the U.S.

population. From a practical standpoint,

the NCHS health examination surveys

are not designed to provide separate

reliable growth estimates for each of the

racial-ethnic groups in the United States.

Even after pooling data sets from the

various national surveys, the sample

sizes for the individual major

racial-ethnic groups in the NCHS

surveys did not meet statistical

requirements for precise estimates of

outlying percentiles (33).

Given the evidence that differences

in growth are primarily due to

environmental and socioeconomic

constraints, in combination with

insufficient data for each racial-ethnic

group, the development of separate

racial-ethnic growth charts for various

groups that constitute the U.S.

population was neither justified nor

practical. Even if sufficient data were

available, it would be difficult to

develop and to apply ethnic-specific

growth charts because many children are

ethnically diverse.

Assessing the Growth of

Breast-Fed Infants

The 1977 NCHS Growth Charts for

infants were based entirely on data from

the Fels Research Institute collected

1929–75. In this study population, as in

the general population during this

period, infants were mainly formula-fed,

although a small percent were

exclusively breast-fed for 3 months. In

addition, it is possible that infants in the

Fels Longitudinal Study were

supplemented early with solid foods,

which could have an impact on growth

that would be reflected in growth charts

constructed from these data (56).

The 2000 CDC Growth Charts

include data for formula-fed and

breast-fed infants, proportional to the

distribution of breast- and formula-fed

infants in the population. During the

past two decades, approximately

one-half of all infants in the United

States received some breast milk and

approximately one-third were breast-fed

for 3 months or more (57). By replacing

data from the Fels Research Institute

with national survey data collected from

1970 to 1994, the combined growth

patterns of breast-fed and formula-fed

infants in the U.S. population are

represented.

Breast-feeding is recommended as

the feeding method of choice for most

full-term infants during the first 6

months after birth and should be

continued with the addition of solid

foods through the first 12 months (58).

The association between breast-feeding

and size and growth in infants has been

the topic of many investigations. In

general, breast-fed infants tend to gain

weight more rapidly in the first 2–3

months. From 6 to 12 months breast-fed

infants tend to weigh less than

formula-fed infants (18,59). These

observations have led to recommendations

for the development of new infant growth

references based on healthy breast-fed

infants (18,19,60,61). A study sponsored

by the WHO is currently collecting data at

study centers in six countries. These data

will be used to develop a new

international growth reference.

Body Mass Index-for-Age

Growth Charts

Body mass index (BMI; kg/m2) has

been recommended for use in children,

adolescents, and adults to assess weight,

adjusted for stature (34,35,62). BMI

tracks over time and the tracking tends

to increase at older adolescent

ages (64,65). By age 8 years, however,

most children are in the percentile range

they will follow until the end of

growth (65,66).

The pattern of the BMI curves

indicates that BMI increases rapidly

from birth to approximately 8 months of

age, then decreases until approximately

age 6 years, when it reaches its nadir

before rebounding, or increasing once

again (67). This has been termed the

adiposity rebound, because it is believed

to be the age when body fatness begins

to increase after reaching a minimum.

This pattern is evident in the revised

growth charts. The younger the age at

which a child’s BMI curve is at its nadir,

the greater the likelihood that the level of

adiposity will be high in adolescence and

early adulthood (66,68,69). Children at

higher percentiles for BMI tend to

achieve their adiposity rebound at

younger ages. These children have a

greater likelihood to track at a higher

BMI percentile with increasing age.

BMI is commonly used in clinical

evaluation of individuals and in

population-based studies. BMI can be

calculated by dividing weight in

kilograms (kg) by stature in meters

squared (m2

). As an alternative to doing

the calculation, BMI can be estimated

from a nomogram or a look-up table

(www.cdc.gov/growthcharts). Available

nomograms have the disadvantage of

approximating BMI only to the nearest

integer. Numeric tables with

precalculated BMI values to the nearest

0.3 units are preferred to intersecting

line nomograms because they provide

greater precision. In clinical assessment,

a transition from the weight-for-length

to the BMI-for-age charts from 24 to 36

months of age becomes possible when

children can stand unassisted and

adequately follow directions to assume

the correct posture for a stature

measurement.

Specialized Charts

Low Birthweight and Very Low

Birthweight Infants

The revised growth charts for the

United States include data on low

birthweight infants but do not include

data on very low birthweight infants

(VLBW; <1,500 gm). Alternate charts

are available to assess the growth of

VLBW infants. Perhaps the most recent

are those developed from data collected

in the National Institute of Child Health

and Human Development Neonatal

Research Network Centers (70). This

recent reference was developed from

data on 478 infants who were

appropriate-for-gestational age and

survived to discharge. Prospective

growth curves are plotted by 200 gm

birthweight intervals for birthweights

ranging from 501 to 1,500 gm.

However, these charts only extend to

about 120 days uncorrected postnatal

age or until a body weight of 2000 gm.

These charts have a very limited range

of use. Perhaps the best general

reference available for VLBW infants is

the Infant Health and Development
Page 14 [ Series 11, No. 246

Program (IHDP) reference (71,72,73),

although it has limitations. The IHDP

growth charts may be considered to

assess the growth of VLBW infants

from an age corrected for gestation of

40 weeks to 36 months. However, the

IHDP charts are based on data collected

in 1985, which was before current

medical and nutritional care practices

were being used. VLBW infants may

show more accelerated growth in

weight-for-age during the first 6 months

of age corrected for gestation than

depicted in the IHDP reference and will

be lighter for their length than the

reference until they are 60 cm long,

becoming increasingly heavier for their

length than the reference after 60 cm.

Alternatively, the new 2000 CDC

Growth Charts can be used to assess

VLBW infants, but their measurements

may fall in the lower percentiles.

Length-for-age will show catch up

between 18 and 30 months and

weight-for-age will fall in the lower

percentiles but follow a similar pattern

to the CDC growth charts.

Children With Special Health

Conditions

A variety of health conditions such

as Down syndrome, cerebral palsy,

Turner syndrome, and others affect

growth status. There are specialized

charts that may be considered for use

with children affected by these

conditions (74–76). These specialized

growth charts provide useful growth

references, but may have some

limitations. Generally, they are

developed from relatively small samples.

One option is to plot the growth patterns

of these children on the specialized

charts and the CDC growth charts. This

will allow comparisons of growth to the

general population of children and to the

references for children identified with a

given condition. In most cases, BMI

charts are not available for special

conditions, and the CDC charts would

provide a useful reference to monitor

weight in relation to stature.

General Growth Chart

Principles

Growth References and

Standards

The distinction between a growth

reference and a growth standard is

relevant to the development and

application of growth charts. The WHO

working groups (61,77) have defined a

reference as a tool for providing a

common basis for purposes of

comparison, and a standard as

embodying a concept of a norm or

target, that is, a value judgment. In

simple terms, a reference describes

‘‘what is,’’ whereas a standard prescribes

‘‘what should be.’’ In practice, however,

reference values are often used as a

standard (78). Growth references are

intended to be used to screen and

monitor growth in individuals and

populations. They are not intended to be

the sole independent diagnostic

instruments upon which clinical

decisions are made.

In the development of the 1977

NCHS Growth Charts, the task force

adhered strictly to a policy of no data

adjustments (8). In the development of

the 2000 CDC Growth Charts, two

notable data exclusions were made. The

first exclusion was of data for all

VLBW infants and the second was of

body weight observations for NHANES

III subjects ages 6 years or over. The

exclusion of VLBW infants was based

on the fact that alternative growth

references are available and are

appropriate to monitor the unique

growth patterns of VLBW infants.

The exclusion of NHANES III body

weight data for children and adolescents

was made after consultation with

numerous experts. Although this meant

straying from a pure reference, the

advantages of excluding these data were

judged to outweigh the disadvantages.

Had these data been retained, the

increase in body weight among

NHANES III subjects would have

shifted the weight- and BMI-for-age

percentile curves upward. This would

have led to identifying fewer children

and adolescents as overweight or at risk

of overweight. The revised U.S. growth

charts are still intended to be growth

references.

In addition to data exclusions, there

were some minor data adjustments and

inclusions of data that were not

nationally representative. The length

data were adjusted to integrate them

with stature data in the smoothing

process. State data were used for length

at birth and weight-for-length at birth,

Fels data were used for head

circumference at birth, and PedNSS data

were used for length-for-age from 0.5 to

5.0 months. These approaches were

taken to provide more complete and

accurate charts, and do not diminish

their use as growth references based on

well-defined data sources.

Roles of Cross-Sectional and

Longitudinal Data in Growth

Charts

There is a difference between

growth (or size) charts and growth

velocity charts (8). The 2000 CDC

Growth Charts for the United States are

based primarily on cross-sectional

national survey data that were

statistically smoothed to create

percentile curves. The curves were

superimposed on grids that permit

interpretation of an individual’s attained

body size (weight, length or stature, and

head circumference) at given ages, or

weight at given lengths or statures, in

comparison with the body sizes of

children in the reference population.

Therefore, these charts more

appropriately may be considered size

charts. When serial values for an

individual are plotted, assessments can

be made of that individual’s growth

progress over time.

Growth velocity charts are

constructed from incremental data

obtained from longitudinal observations.

Growth velocity charts are more

sensitive indicators of small changes in

growth status than the size-attained

charts, and are more useful when

evaluating changes in growth rates that

are important in selected growth

disorders and therapies. Incremental

growth charts and growth tables for
6-month increments have been

developed using weight, recumbent

length, stature, and head circumference

data from the Fels Longitudinal

Study (79,80).

Percentiles and Z-Scores

Smoothed percentile curves and

z-scores are used to evaluate the growth

of children. Percentiles are the most

commonly used clinical indicator to

assess the size and growth patterns of

individual children in the United States.

Percentiles rank the position of an

individual by indicating what percent of

the reference population the individual

would equal or exceed. For example, on

the weight-for-age growth charts, a

5-year-old girl whose weight is at the

25th percentile, weighs the same or

more than 25 percent of the reference

population of 5-year-old girls, and

weighs less than 75 percent of the

5-year-old girls in the reference

population.

A z-score is the deviation of the

value for an individual from the mean

value of the reference population

divided by the standard deviation for the

reference population. Because z-scores

have a direct relationship with

percentiles, a conversion can occur in

either direction using a standard normal

distribution table. Therefore, z-scores

and percentiles are interchangeable.

Which one is used is based primarily on

convention or preference. In certain

population-based applications, such as

research settings and surveillance systems,

the mean and standard deviation are often

calculated for a group of z-scores (61). In

selected clinical situations where growth

monitoring is an important evaluation tool

and greater measurement precision is

necessary, z-scores or exact percentiles

may be preferred by clinicians.

To track growth below the 5th

percentile, z-scores achieved widespread

use. A z-score of –2 SD is accepted as a

standard statistical cutoff point to

determine the need for nutritional

intervention and corresponds

approximately to the 3rd percentile

(z-score at 3rd percentile = 1.88) (77).

Because the LMS values were

calculated by solving equations that

used the values for percentiles ranging

from the 3rd to the 97th, the outermost

percentiles less than the 3rd or greater

than the 97th are beyond the range of

the data. The sample sizes for the data

used to calculate the growth charts were

not adequate to calculate percentiles

below 3 and above 97, corresponding to

z-scores of –1.88 and 1.88.

Extrapolation beyond this range of the

data should be done with caution. In

addition, a solution may not be obtained

when both the Z and L are high and

have opposite signs. Moreover, some

z-score values may have extreme

corresponding measurement values. For

these reasons, any use of the LMS

values to calculate z-scores below

–2 (2.3 percentile) or above 2 (97.7

percentile) should be done with an

awareness of the limitations. Z-scores

and exact percentiles can be calculated

using formulas and data tables available

on the Internet (www.cdc.gov/

growthcharts) or in the revised

nutritional anthropometry module

(NutStat) of CDC’s Epi Info 2000. Epi

Info is a public domain computer

program available on the Internet

(www.cdc.gov/epinfo).

Conclusions

The purpose of this revision to the

1977 NCHS Growth Charts was

to provide better estimates of size

and growth, using more comprehensive

national survey data and improved

statistical smoothing procedures. To

construct clinically useful growth charts,

it is necessary to have access to a

reference population, to obtain

anthropometric data, and to statistically

smooth the observed data. In developing

such reference data for children, it is not

feasible to conduct a study that would

obtain measures on the total U.S.

population of children and adolescents.

Instead, the reference population for the

revised U.S. growth charts was

primarily based on statistically

representative samples of the U.S.

pediatric population, measured in a

series of cross-sectional surveys from

1963 to 1994, that were supplemented

with limited data from other sources.

Replacing the Fels data in the 1977

Series 11, No. 246 [ Page 15

NCHS infant charts with national survey

data addressed one of the major

concerns with the 1977 charts.

National survey data, in

combination with improved statistical

smoothing procedures, produced curves

with better transitions between the infant

and older child curves from 24 to 36

months of age than were found in the

1977 curves. The statistical procedures

used to generate the 2000 growth charts

will allow users to calculate percentiles

and z-scores that are completely

interchangeable. This is an improvement

over the 1977 NCHS charts where they

often did not agree.

A major shortcoming in the

1977 NCHS charts was the inability to

calculate a weight-for-stature value

for post-pubertal adolescents. Overweight

in children and adolescents is becoming

more common in the United States (81–

83), and screening tools are needed to

identify individuals and population

groups at risk. Expert committees have

recommended use of the BMI to

identify children who are overweight or

at risk of becoming overweight (34,35).

Development of the new BMI-for-age

growth chart for boys and girls from 2

to 20 years of age provides a screening

instrument to monitor weight adjusted

for stature.

The 2000 CDC Growth Charts for

the United States are intended to serve

as a reference to evaluate physical size

and growth for the majority of the

pediatric population. For preterm,

VLBW infants and children with

specific conditions that may affect size

and growth, various charts are available

for alternative use, although most of

these were developed from restricted

samples that were not based on

nationally representative survey data.

Differences between the 1977 and

the 2000 growth charts have been

illustrated in this report. In clinical

practice most of these differences will

not affect the way in which current

evaluations are made. Substitution of the

2000 CDC charts for the 1977 NCHS

charts in research, surveillance, food

assistance, and other population-based

activities may affect the classification of

some individuals.

The revised growth charts should

continue to meet the many uses that
Page 16 [ Series 11, No. 246

growth charts currently serve in the

United States. Users are encouraged to

make the transition from the 1977

NCHS Grow Charts to the 2000 CDC

Growth Charts. To facilitate this

transition, master copies of the 2000

CDC Growth Charts are available on the

Internet as high resolution graphics with

guidelines for reproducing multiple

copies (www.cdc.gov/growthcharts).

CDC has made available camera-ready

negatives to State health offices, and

copies are also available through some

infant formula manufacturers and

professional organizations such as the

American Academy of Pediatrics.

Various proprietary software programs

are available that incorporate the 2000

CDC Growth Charts in electronic

formats, and CDC has included the

normalized 1977 and the 2000 growth

charts in the NutStat module of Epi

Info 2000.

As the 2000 CDC Growth Charts

are used in various applications, they

will continue to be evaluated. Through

this process, additional knowledge will

be gained to give direction for future

improvements in pediatric growth charts

for the United States.

Aseries of four workshops that

dealt with topics germane to the

growth chart revision were

sponsored by the Division of Health

Examination Statistics at National

Center for Health Statistics. Selected

highlights of these workshops are

described below. Workshops 1, 3, and 4

were co-chaired by Dr. Robert

Kuczmarski and Dr. Alexander Roche.

Workshop 2 was chaired by Dr. John

Himes.

Workshop 1

In December 1992, NCHS

sponsored the first workshop to address

a number of concerns that had been

identified about the1977 NCHS Growth

Charts and to solicit recommendations

on approaches that could be taken in the

revision process. A group of experts

from various Federal agencies and

academic institutions (table I) addressed

the following questions:

+	 How and when should the 1977

NCHS Growth Charts be updated

data?

+	 Should ethnic-specific charts be

created, perhaps at least for white

non-Hispanic and black nonHispanic populations and Mexican

Americans, if adequate sample sizes

were available?

+	 Should growth patterns and sexual

maturity data be incorporated in the

revised growth charts?

+	 What data should be used to

develop charts for the age range

birth to 3 months where NHANES

III data were insufficient?

+	 What curve smoothing procedures

should be considered and used?

+	 Should the curves be constructed

only for the measures in the 1977

charts or should different measures

be considered?

+	 Should electronic formats be

considered and developed or should

there be a continued reliance on

paper and pencil formats?

This workshop successfully dealt

with many of these issues and provided

a framework for the overall revision

process. It became clear in the course of

discussions, however, that additional

topics would require further attention.

These are discussed below. The

deliberations at this workshop have been

summarized (16).

Workshop 2

One topic from the first workshop

that required additional discussion was

the source of data to be used from birth

to age 3 months. Consequently, a second

dedicated workshop was held to discuss

the feasibility and describe the potential

design of an ancillary research project to

collect early infancy growth data

(table I). At this workshop

characteristics of a special infant study

were identified, and included the

following:

+	 The design should be a crosssectional, multicenter, hospital-based

study with six sites, each including a

single cooperating hospital with at

least 3,000 births annually.

+	 Infants should be selected to reflect

the national variation in

socioeconomic status and ethnicity

and measured at a central data

collection center at each site from

age 1 to 24 weeks.

+	 The target sample should consist of

500 healthy infants without physical

limitations at each site, for a total

sample of 3,000 infants.

+	 Data collected should include

weight, recumbent length, head

circumference, feeding history

(breast, formula, etc.), and

participation in public assistance

programs, in addition to information

detailed on the U.S. Standard

Certificate of Live Birth.

This study would have been the

most desirable option to fill in the data

gaps for ages in early infancy. However,

the cost of this project was estimated at

$1.3 million in 1994, and it was not

possible to locate the resources

necessary to proceed.

Workshop 3

Another topic identified in the first

workshop was the issue of whether low

birthweight infants should be included in

the revised growth charts for the United

States. Therefore, a third workshop was

held in which experts with clinical and

public health experience in low

birthweight participated (table I). A

summary of this workshop is

available (84). Some key points in favor

of excluding low birthweight infants

(<2,500 gm) are as follows:

+ Preterm low birthweight (LBW;

1,500–2,500 gm) and very low

birthweight (VLBW; <1,500 gm)

infants differ in growth status from

term infants of normal birthweight,

even after chronological ages are

adjusted for gestational age.

+ VLBW infants might still be

hospitalized at 2–3 months and

would not be included in the

NHANES III sample.

+ Separate LBW and VLBW charts

already exist, such as those of the

Infant Health and Development

Program (IHDP).

+ Clinicians would be able to select

appropriate charts confidently

because maternal recall of

birthweight is generally accurate.

The major considerations in favor

of retaining the LBW infants in the

revised charts included the following:

+ The IHDP charts were developed for

preterm LBW infants. National

natality data indicated that about

49 percent of babies born <2,500 gm

are not preterm and more than 50

percent of infants born between

2000–2,500 gm are not preterm.

+ Many users may not be familiar

with specialized charts such as the

IHDP charts, and which may not be

readily available.

+ Excluding infants with birthweights

<2,500 gm would tend to make the

revised charts more of a standard

and less of a reference.

+ Excluding at the 2,500 gm level

would leave out approximately

7.5 percent of all children and

approximately 15 percent of all

black infants born in the United

States for whom the general, revised

NCHS charts would not be

applicable.

Subsequently, the final decision was

to exclude only VLBW infants. For

these children, specialized charts, such

as the IHDP charts are available from

birth to 3 years (71–73,85). The

rationale is that at this level (<1,500

gm), virtually all children are preterm,

their growth is markedly different from

the growth of higher birthweight, term

infants, and less than 1 percent of all

children born in the United States would

be excluded.

Workshop 4

Analyses of NHANES III data

indicated that an increasing trend in

body weight was occurring among

children, adolescents, and adults in the

United States between the time of the

NHANES II and NHANES III surveys

(86–89). Consequently, a fourth

workshop focused on the implications of

this secular trend in body weight for the

growth charts (table I). The alternative

methods for pooling multiple data sets

were also considered during the course

of this meeting. A summary of this

workshop is available (90).

A review of the data indicated there

was an increase in weight that was most

pronounced at the upper percentiles of

the distribution for males and

females (91). Ultimately, it was

important to know how including the

NHANES III subjects in the pooled

sample would influence the weight and

BMI curves. If including heavier

subjects from NHANES III in the

combined data set from the five surveys

elevated the percentiles to a

substantially higher level, one option

would be to exclude the NHANES III

data. When NHANES III data were

included, there was an effect on the

higher percentile curves that became

consistent at about 6 years of age. Using

information discussed at this workshop,

a decision was subsequently made to

exclude the NHANES III weight and

BMI data for ages 6 years and over

from the revised growth charts.
