`
`Abstract
`Objective—This report presents national anthropometric reference data for
`all ages of the U.S. population in 2003–2006, adding to results published
`previously from 1960–2002.
`Methods—Data are from the National Health and Nutrition Examination
`Survey (NHANES), a complex, stratified, and multistage probability sample of
`the civilian, noninstitutionalized U.S. population. Anthropometry measurements
`were obtained from 19,593 survey participants. The anthropometric measures
`included weight, height, recumbent length, circumferences, limb lengths, and
`skinfold thickness measurements.
`Results—The tables in this report include weighted population means,
`standard errors of the means, and selected percentiles of body measurement
`values. Because measurements varied by sex and age (as well as race and
`ethnicity in adults), results are reported by these subgroups.
`Conclusions—These latest NHANES data add to the knowledge about trends
`in child growth and development and trends in the distribution of body
`measurements, such as weight and height, in the U.S. population.

`
`Introduction
`The field of anthropometry
`encompasses a variety of human body
`measurements, such as weight, height,
`and size, including skinfold thicknesses,
`circumferences, lengths, and breadths.
`Anthropometry is a key component of
`nutritional status assessment in children
`and adults (1). Anthropometric data for
`
`children reflect general health status,
`dietary adequacy, and growth and
`development over time. In adults, body
`measurement data are used to evaluate
`health and dietary status, disease risk,
`and body composition changes that
`occur over the adult lifespan. This report
`provides anthropometric reference data
`for U.S. children and adults of all ages.
`
`Methods
`National Health and Nutrition
`Examination Surveys (NHANES) are
`conducted by the the Centers for
`Disease Control and Prevention’s
`National Center for Health Statistics
`(NCHS). NHANES data are the primary
`source of body measurement and related
`health and nutrition data for the civilian,
`noninstitutionalized U.S. population.
`Surveys were conducted on a periodic
`basis from 1960 to 1994. NHANES
`became a continuous survey in 1999.
`Each of the continuous NHANES
`annual survey samples is nationally
`representative; 2 or more years of data
`are required for subgroup analyses (2).
`NHANES 1999–2006 data were released
`publicly in four data sets, each one
`spanning 2 years (1999–2000, 2001–
`2002, 2003–2004, and 2005–2006)
`(3–5). A combined 4-year dataset based
`on 2003–2004 and 2005–2006 data was
`used for this report to improve the
`stability and reliability of the statistical
`estimates (4–5). Additional 2-year data
`sets will be released in the future as
`more data become available.
`Household interviews and health
`examinations are used to collect
`NHANES data. All health examinations

`
`are conducted in mobile examination
`centers. The examination centers are
`staffed by full-time personnel, including
`health technicians who obtain body
`measurements from survey participants.
`All of the NHANES health technicians
`completed a comprehensive body
`measurement training program that
`utilized videotape, demonstration, and
`practice exercises with an expert
`examiner. Health technician performance
`was monitored by means of direct
`observation, data review, and expert
`examiner evaluations.
`Although portions of the health
`examination component have varied
`during the surveys’ history, much of the
`anthropometry component methodology
`has remained consistent over time. The
`NHANES anthropometry examinations
`are completed in a room that is
`equipped with a digital scale, a wall-
`mounted stadiometer, a bench, a wall
`mirror, an infantometer, and a computer
`workstation. A health technician
`performs the anthropometry exam and is
`assisted by a recorder. NHANES
`subjects wear socks and disposable
`examination gowns during the
`examination. The use of consistent data
`collection methods in representative
`population samples makes possible the
`examination of trends in body
`measurements over time in the U.S.
`population.
`
`Sample description
`NHANES is a complex, multistage
`probability sample of the civilian
`noninstitutionalized U.S. population. The
`NHANES 2003–2006 sample included
`participants of all ages. Adolescents
`12–19 years of age, persons 60 years of
`age and older, Mexican Americans,
`black persons, and low-income persons
`were oversampled to improve the
`precision of the statistical estimates for
`these groups. Additional information
`pertaining to the NHANES 2003–2006
`survey design, survey methodology, and
`public-use data is available on the
`NHANES website (4–5).
`The analytic sample for this report
`was based on the 2003–2006 examined
`sample of 19,593 persons. Pregnant
`
`females were excluded from the
`tabulations of weight, body mass index
`(BMI), circumference measurements,
`and skinfold thickness data.
`
`Anthropometry examination
`component
`
`The NHANES 2005–2006
`Anthropometry Training and Procedures
`Manual describes the protocol,
`equipment, quality control, and
`measurement procedures that were used
`during the NHANES anthropometry
`examination (6). An anthropometry
`methodology videotape that was
`produced during NHANES III (1988–
`1994) illustrates the NHANES
`anthropometry methodology that was
`used to collect the 2003–2006 data (7).
`Weight was measured to the nearest
`0.1 kilogram. Stature, length, and
`circumference measurements were made
`to the nearest millimeter. Skinfold
`thickness measures were made to the
`nearest 0.1 millimeter. Weight was
`measured using a digital floor scale, and
`an infantometer was used to measure
`recumbent length on infants and young
`children. Standing height was measured
`with a wall-mounted stadiometer. Head
`circumference measurements were made
`using a plastic head circumference
`measurement tape. Upper arm length
`was measured with a tape measure from
`the posterior border of the acromion
`process to the tip of the olecranon
`process; during the measurement the
`upper arm length midpoint was marked.
`The mid-arm circumference was
`measured with a tape measure. Triceps
`and subscapular skinfolds were
`measured with a skinfold caliper. Waist
`circumference was measured with a tape
`measure at the uppermost lateral border
`of the hip crest (ilium). Weight,
`recumbent length, and standing height
`values were recorded automatically. The
`other body measurement data were
`recorded using computer-assisted data
`entry, and all results were based on a
`single body measurement examination.
`In addition to the measurements
`above, three additional measurements
`were taken on participants aged 8 years
`and older. Upper leg length
`measurements were taken on seated
`
`participants; the distance from the
`inguinal crease to the distal end of the
`femur was measured. Maximal calf
`circumference was also measured in a
`seated position; a measurement tape was
`positioned around the calf at the point
`of maximum circumference. Mid-thigh
`circumference was measured on
`standing participants with the
`measurement tape placed around the
`mid-thigh, perpendicular to the long axis
`of the femur bone.
`
`Statistical analysis
`Population means, standard errors
`of the means, and percentiles were
`weighted using the NHANES
`examination sample weights to produce
`national estimates. The NHANES
`examination sample weights incorporate
`the differential probabilities of selection
`and include adjustments for
`oversampling of selected populations,
`noncoverage, and nonresponse. Standard
`errors were estimated using SUDAAN
`by Taylor series linearization because of
`the complex sample design (8).
`The reliability of the estimates
`produced for this report was evaluated.
`The relative standard error (RSE),
`calculated as the standard error divided
`by the estimate, and minimum sample
`size criterion were used. NCHS
`recommends that an estimate with an
`RSE greater than 30 percent be
`considered unreliable (2). The
`recommended minimum sample sizes
`were based on a combination of the
`average design effects and specified
`proportions (or percentiles) (9). The
`average design effects reflect the impact
`of the complex sample design on
`variance estimates. They were calculated
`as the ratio of the variance of a statistic
`(accounting for the complex sample
`design) to the variance of the same
`statistic based on a hypothetical simple
`random sample of the same size.
`Average design effects were calculated
`for each anthropometry variable over
`sex for children and adolescents and
`over sex and race-ethnicity for adults
`aged 20 years and older. Minimum
`sample sizes for a specified design
`effect and percentile were obtained from
`published tables (9). The percentile

`
`estimates that did not meet the standards
`for either RSE or minimum sample size
`were replaced with asterisks (Tables 1–
`41).
`The age categories used for adults
`aged 20 years and older were based on
`the survey sample domains that were
`recommended in the NHANES Analytic
`Guidelines (2). The results for
`participants who were under 20 years of
`age are by single years or, in the case of
`infants under 1 year of age, single
`months of age.
`
`Results
`The anthropometric measurements
`that were performed in the survey are
`listed in Table A. Results for children
`
`are reported by sex and age group, and
`the results for adults aged 20 years and
`older are also presented by sex,
`race-ethnicity group, and age. Results
`from previous surveys for most
`measurements have been reported for
`the National Health Examination Survey
`and NHANES conducted from 1960–
`2002 (10–30).
