Objectives

This report presents bone

measurement data from total body dual

energy x-ray absorptiometry scans for

28,454 persons aged 8 years and over

who participated in the 1999–2006

National Health and Nutrition Examination

Survey. The sample consisted of 22,667

respondents with valid data, and 5,787

with missing data that were successfully

multiply imputed (i.e., not highly variable).

Bone area, bone mineral content, and

bone mineral density (BMD) are presented

for the total body, the total body minus the

head (e.g., subtotal), and 10 subregions of

the body.

Methods

Means, standard deviations, and

selected percentiles were calculated for

the total body, total body minus head

(subtotal), and 10 body subregions by sex,

race and ethnicity, and age. Smoothed

mean total body BMD was plotted by age,

sex, and race and ethnicity. Multiple

regression was used to evaluate

differences in mean total body BMD by

age, sex, and race and ethnicity.

Results

After adjusting for race and ethnicity,

total body BMD among those under age

20 was significantly higher in respondents

aged 12–19 than in those aged 8–11 in

both sexes. Among adults of both sexes,

total body BMD in persons aged 20–49

was significantly higher than in those aged

50–79, and significantly lower in persons

aged 80 and over than in those aged

50–79, after adjusting for race and

ethnicity. After adjusting for age, total body

BMD was significantly higher in

non-Hispanic black persons than in

non-Hispanic white persons, regardless of

age or sex. However, the pattern differed

by age when Mexican-American persons

were compared with non-Hispanic white

persons: Age-adjusted total body BMD

was significantly lower among MexicanAmerican males aged 8–19, was similar in

Mexican-American females aged 8–19,

and was significantly lower in MexicanAmerican men and women aged 20 and

over.

Introduction

Dual energy x-ray absorptiometry

(DXA) has long been accepted as the

primary method for measuring bone

mineral content (BMC) and bone

mineral density (BMD) because of its

high precision, accuracy, and low

radiation exposure (1–5). More recently,

whole body DXA also has become one

of the most widely accepted methods of

measuring body composition due to its

speed, ease of use, and strong

correlation with criterion methods of

assessing body composition (6). In

addition, DXA has shown to be

comparable in reliability and accuracy to

computed tomography and magnetic

resonance imaging in assessing body

composition in defined regions such as

the arms, legs, and trunk (7–9).

In 1999, the National Health and

Nutrition Examination Survey

(NHANES) implemented whole body

DXA scans of survey participants aged

8 years and over to provide nationally

representative body composition data for

the U.S. population. This report presents

bone measurement data from whole

body DXA scans for persons aged 8 and

over who participated in the 1999–2006

NHANES. This report expands on

previous publications of NHANES total

body DXA data (10–12) by providing

detailed data on bone area, BMC, and

BMD for all body subregions. In

addition, this report incorporates data

from the 2005–2006 NHANES that

were not available at the time of the

previous reports.

Methods

Data Source

NHANES is conducted by the

Centers for Disease Control and

Prevention’s National Center for Health

Statistics (NCHS) to assess the health

and nutritional status of a large

representative cross-sectional sample of

the noninstitutionalized civilian U.S.

population (13). All procedures in

NHANES 1999–2006 were approved by

the NCHS Institutional Review Board.

Parental permission was obtained for

minors under age 18. Children aged

7–17 were also asked to provide

documented assent. Consent was

obtained for all adults aged 18 and over.

Data were collected in NHANES

1999–2006 through household

interviews and direct standardized

Page 1
Page 2 [ Series 11, No. 253

physical examinations that were

conducted in specially equipped mobile

examination centers (MECs) (13).

NHANES 1999–2006 was designed to

provide reliable estimates for three

racial and ethnic groups: non-Hispanic

white, non-Hispanic black, and Mexican

American. Race and ethnicity were

self-reported by the participants.

Dual Energy X-ray

Absorptiometry

Component

Survey participants aged 8 and over

in 1999–2004 and aged 8–69 in

2005–2006 were eligible to receive a

total body DXA scan, unless they were

pregnant; reported exposure to

radiographic contrast material (barium)

use in the past 72 hours or exposure to

nuclear medicine studies in the past 3

days; or exceeded the weight or height

limits of the DXA table (i.e., weighed

more than 300 pounds or were taller

than 6 feet and 5 inches). Additionally,

females aged 8–17 were excluded from

the DXA component in 1999 so that

concerns about reporting pregnancy test

results for minors could be resolved. See

‘‘Analytic Sample’’ for a description of

how individuals with missing data were

handled in the analyses used in this

report.

The DXA scans were acquired with

a Hologic QDR 4500A fan-beam

densitometer (Hologic, Inc., Bedford,

M.A.) and with Hologic software,

version 8.26:a3*. All scans were

administered by certified radiology

technologists. Details of the DXA

examination protocol are documented in

the Body Composition Procedures

Manual on the NHANES website (14).

A high level of quality control was

maintained throughout the DXA data

collection and scan analysis.

Technologist performance was

monitored through in-person

observations in the field and scan

review, with feedback provided as

needed. Retraining sessions were

conducted annually, and as needed, to

reinforce correct techniques and

appropriate protocol. Each participant

scan was reviewed and analyzed by the

NHANES quality control center at the

University of California, San Francisco

(UCSF), Department of Radiology,

using standard radiologic techniques and

study-specific protocols developed for

NHANES. All participant scans were

reviewed by a second technologist, and

differences were adjudicated by a

supervisor. Hologic Discovery software,

version 12.1, was used to analyze the

scans. Codes to indicate invalidity were

applied by UCSF to regions of the body

that could not be analyzed accurately.

Reasons for invalid regions included:

1.	 Jewelry and other objects not

removed

2.	 Nonremovable objects (e.g.,

prostheses, implants, or casts)

3.	 Excessive x-ray ‘‘noise’’ due to

truncal adiposity

4.	 Arm and leg overlap

5.	 Body parts out of the scan field

6.	 Positioning problems

7.	 Participant motion

8.	 Scanner failed

9.	 Other (e.g., missing limbs, unknown

artifacts, or fracture)

During the 1999–2006 DXA data

collection, quality-control phantoms

specific to each MEC, and phantoms

that circulated among the MECs, were

scanned according to a rigorous

schedule to provide cross-calibration and

longitudinal monitoring. Spine phantoms

specific to each MEC were scanned

daily, as required by the manufacturer,

to ensure accurate calibration of the

densitometer. MEC-specific whole body

and tissue-step phantoms were scanned

one to three times weekly. Phantoms

simulating tissue or bone were used to

quantify the accuracy and precision of

DXA densitometers in order to detect

drift or changes in measurement

accuracy over time. A set of phantoms

that included a spine phantom, block

phantom, and whole body phantom

circulated among the MECs and were

scanned at the start of operations at each

survey site. Air scans, which are

phantomless scans of the scan field

using the whole body scan mode, were

used to monitor radiographic uniformity

across the entire scan field. The

phantom scanning schedule is described

in the Body Composition Procedures

Manual (14).

UCSF used the cumulative statistics

method (CUSUM) and the MECspecific phantom data to determine

breaks in the calibration of the

densitometers over the course of the

survey (15). NCHS evaluated the effect

of adjustment factors developed by

UCSF from cross-calibration data

collected before the start of data

collection in 1999 and from the

longitudinal monitoring data on the

participant data. The magnitude of the

adjustment was determined to be

insignificant, and correction of the

participant data was not required.

The DXA scans provided bone

measures for both arms and both legs,

left and right ribs, pelvis, thoracic spine,

lumbar spine, and head. Values for the

total body and body subregions include

bone area (cm2

), BMC (g), and BMD

(g/cm2

). Total values were calculated by

summing measurements for all body

subregions. Total body minus head

(subtotal) values were calculated by

summing measurements for all body

subregions except the head.

Analytic Sample

Respondents with missing total

body DXA data were not a random

subset of the eligible sample. Details

about characteristics of respondents with

missing total body DXA data have been

published elsewhere (12). Specifically,

the percentage of eligible participants

with valid data decreased with

increasing age (primarily due to an

increase in implants such as pacemakers,

stents, and hip replacements) and with

increasing body mass index (primarily

due to truncal adiposity, which

interfered with the ability to obtain valid

measurements) (12). To address this

potential bias, multiple imputation of

missing data for the total body and body

subregions was performed using a

sequential regression multivariate

imputation procedure, which is

described in detail elsewhere (16,17).

The regression models used to impute

the data used a large number of

predictor variables, including DXA data

for any nonmissing total body

subregions, as well as demographic,

socioeconomic, and geographic

variables; anthropometric measurements;
Series 11, No. 253 [ Page 3

health indicators; dietary intake and

medication use; blood test results; and

variables related to the design of the

NHANES sample.

Data were multiply imputed for all

sample persons in the eligible age range

for this examination, except pregnant

women and those with limb amputations

other than fingers or toes. Specifically,

in addition to persons with invalid DXA

scan data, results were imputed for

females aged 8–17 from 1999, persons

with exposure to radiographic contrast

or nuclear medicine materials, and

persons who exceeded the DXA table

size limitations. The imputed data for

these individuals are included in this

report. However, the imputed values of

438 respondents were found to vary

greatly among the different imputed data

sets. Review of the data for these

participants showed that values were

missing for all DXA measurements, as

well as measured height and weight

(important predictor variables in the

imputation models). Because of the

extreme variability of their imputed

DXA data values, the data for these 438

respondents were not included in this

report.

This report uses the total body

DXA measurements for 28,479

respondents aged 8 and over (those aged

8–69 for 2005–2006) with complete

total body DXA data, including 5,787

with imputed values that were not

highly variable between the imputed

data sets (e.g., values that did not lack

measurements of height, weight, and all

DXA data, as described above). These

data represent 87% of the participants

aged 8 and over who were interviewed

(n = 32,819) and 92% of those who

were interviewed and examined (n =

31,085).

Statistical Analysis

Means, standard deviations, and

percentiles for bone area, BMC, and

BMD are presented by sex and age for

all racial and ethnic groups combined,

and for Mexican-American, nonHispanic white, and non-Hispanic black

population subgroups separately. The

analytic age groups used were: 8–11,

12–15, 16–19, 20–29, 30–39, 40–49,

50–59, 60–69, 70–79, and 80 and over.

Data analyses were performed using

the statistical packages SAS, version 9.3

(SAS Institute, Cary, N.C.); and

SUDAAN, version 11.0 (RTI

International, Research Triangle Park,

N.C.); or with the R survey package

(University of Washington, Seattle

W.A.) (18). The SUDAAN MI-COUNT

option was used to accommodate the

multiply imputed data. Standard errors

and standard deviations of the means

were estimated by Taylor Series

Linearization (19), a method that

incorporates the sample weights and

accounts for the NHANES complex

sample design. Eight-year MEC weights

were applied to the data to account for

differential probabilities of selection,

nonresponse, and noncoverage.

Estimates were considered statistically

reliable if their relative standard error

(RSE) was less than 30% and they were

based on 12 or more degrees of

freedom. The RSE is defined as the

ratio of the standard error of the

estimate divided by the estimate

multiplied by 100. In the tables,

estimates that do not meet criteria for

statistical reliability are identified with

an asterisk. Estimates whose standard

errors were not calculable using

SUDAAN due to small cell sizes were

omitted from the tables. Means for

adults aged 20 and over shown in the

tables were age-adjusted to the U.S.

2000 standard population to facilitate

comparisons between the sex and race

and ethnicity subgroups (20). The age

groups used to age-adjust these means

were 20–29, 30–39, 40–49, 50–59,

60–69, 70–79, and 80 years and over.

Total body BMD data were plotted

by age, sex, and race and ethnicity using

‘‘Svysmooth,’’ a smoothing procedure

available in the R survey package that is

designed for use with surveys with a

complex design (18). Multiple

regression (SUDAAN PROC

REGRESS) was used to assess whether

significant interactions in total BMD

existed between age and sex, age and

race and ethnicity, or sex and race and

ethnicity. Results indicated that

significant interactions existed when all

ages and both sexes were analyzed

together, but not when ages 8–19 and 20

and over were analyzed separately by

sex. As a result, comparisons of total

body BMD by detailed age group or by

race and ethnicity were made by sex

within these two broad age categories.

Multiple regression was used to

compare mean total body BMD by

detailed age group while adjusting for

race and ethnicity and to compare mean

total body BMD by race and ethnicity

while adjusting for detailed age group.

Key Findings

Means; standard deviations; and

percentiles for BMD, BMC, and bone

area of the total body, total body minus

head (subtotal), and 10 body subregions

are shown in Tables 1–36 for persons

aged 8 and over. Patterns in total body

BMD by age, sex, and race and

ethnicity are summarized in Figures 1–3.

+	 Smoothed mean total body BMD

increased until early adulthood and

then remained relatively stable in

males and females in the three racial

and ethnic groups examined until

approximately age 50, after which it

declined with age in both sexes in

the three groups (Figure 1).

+	 Total body BMD was significantly

higher (after adjusting for race and

ethnicity) in respondents aged 12–19

years than in those aged 8–11 years

in both sexes (Figure 2).

+	 Total body BMD was significantly

higher (after adjusting for age) in

non-Hispanic black persons aged

8–19 years than in non-Hispanic

white persons of this age group in

both sexes. But the pattern differed

by sex when Mexican-American

persons were compared with

non-Hispanic white persons:

Age-adjusted total body BMD was

significantly lower among

Mexican-American males compared

with non-Hispanic white males, but

total body BMD was similar among

Mexican-American and nonHispanic white females (Figure 2).

+	 Among adults aged 20 and over,

total body BMD was significantly

lower in each of the three

succeeding age groups tested in both

sexes, after adjusting for race and
