v
Objective

This report presents bone

measurement data from dual-energy X-ray

absorptiometry scans of the lumbar spine

and proximal femur for persons aged 8

years and over from the National Health

and Nutrition Examination Survey

(NHANES) 2005–2008.

Methods

Means, standard deviations, and

selected percentiles were calculated for

the proximal femur and lumbar spine (total

and subregions) by sex, race and

ethnicity, and age. Smoothed mean total

lumbar spine and femur neck bone

mineral density (BMD) were plotted by

age, sex, and race and ethnicity. Multiple

regression was used to test for significant

interactions and to calculate mean total

lumbar spine and femur neck BMD after

adjusting for age, sex, and race and

ethnicity. Differences by sex, race and

ethnicity, and age were summarized by

calculating the percent difference in

adjusted means.

Results

Among scanned individuals, 11%

lacked total lumbar spine data due to

invalid data for one or more lumbar

vertebrae, and 4% had invalid data for

the proximal femur. Non-Hispanic black

persons had 6% higher total lumbar

spine BMD and 9%–10% higher femur

neck BMD than non-Hispanic white

persons. Mean total lumbar spine BMD

and femur neck BMD did not differ

between Mexican-American and

non-Hispanic white persons in those

under age 20. For those aged 20 and

over, Mexican-American persons had 4%

lower total lumbar spine BMD but 1%

higher femur neck BMD than nonHispanic white persons. Mean total

lumbar spine BMD was 8%–17% higher

in females aged 8–15 compared with

males of the same age. In the age group

16–49, mean total lumbar spine BMD

was similar or slightly higher for females

compared with males, but after age 50 it

was 6%–15% lower for females

compared with males. Mean femur neck

BMD was 5%–13% lower for females

than males in all age groups except

12–15.

Introduction

In 2005, the National Health and

Nutrition Examination Survey

(NHANES) implemented lumbar spine

as well as proximal femur dual-energy

X-ray absorptiometry (DXA) scans of

survey participants aged 8 years and

over. The inclusion of lumbar spine

DXA measurements in NHANES

2005–2008 provides the first nationally

representative data for this skeletal site

for the U.S. population. Femur

measurements made on the same sample

can provide information about current

femur skeletal status for the U.S.

population. These two skeletal sites are

among the most commonly used sites to

assess skeletal status among adults. For

example, the World Health Organization

(WHO) recently designated the femur

neck as the preferred skeletal site for

assessing osteoporosis in populations

(1), and it is currently the skeletal site

included in the WHO fracture prediction

model, FRAXt (2). However, a number

of clinical guidelines are based on

measurements at both the proximal

femur and lumbar spine (3–7). The

lumbar spine and proximal femur data

from NHANES 2005–2008 provide the

opportunity to examine demographic

patterns in lumbar spine and proximal

femur bone mineral density (BMD) for

males and females from multiple racial

and ethnic groups across a wide age

range.

Methods

NHANES is conducted by the

Centers for Disease Control and

Prevention’s National Center for Health

Statistics (NCHS). NHANES is a series

of cross-sectional, nationally

representative surveys of the U.S.

civilian noninstitutionalized population.

Samples are selected through a complex,

multistage probability design (8).

Individuals identified for the survey are

initially interviewed in their homes.

Following the household interview,

survey participants are asked to

complete the health examination

component, conducted in mobile

examination centers (MECs), which use

standardized techniques and equipment

for the collection of high-quality data.

For reasons that include disclosure and

reliability issues, the data are released

on public-use data files every 2 years.

The data used for this report are from

2005–2006 and 2007–2008. Public-use

DXA data files and documentation can

be found at the NCHS website for

NHANES (9,10).

Sample Description

The NHANES target population is

the U.S. civilian noninstitutionalized

population. In 2005–2008, the survey

was designed to provide statistically

reliable estimates for non-Hispanic

white, non-Hispanic black, and

Mexican-American persons. In

2007–2008, the survey was also

designed to provide statistically reliable

estimates for ‘‘all Hispanics,’’ but

estimates are not presented separately

for all Hispanics in this report because

the group was not oversampled in

2005–2006. Participants self-reported

race and ethnicity. With the exception of

pregnant females, survey participants

aged 8 and over were eligible for the

DXA scan. Participants were also

excluded from the DXA examination if

they reported radiographic contrast

material (barium) use within the past 7

days or nuclear medicine studies within

the past 3 days, or if they weighed over

300 pounds or were taller than 6’5’’

(due to the DXA device’s physical

limitations). Participants who were

excluded from the DXA scan for

reasons other than pregnancy were

considered to be eligible

nonrespondents.

All procedures in NHANES

2005–2008 were approved by the NCHS

Institutional Review Board. Written

informed consent was obtained from all

participants aged 18 and over prior to

the study. For participants under age 18,

parental consent and child assent was

obtained. A total of 15,026 nonpregnant

participants aged 8 and over were

examined and found eligible for the

DXA examination; this sample size

includes those who did not receive DXA

scans due to body size or safety reasons.

Of this total sample, valid measurements

for the proximal femur were obtained

from 12,593, or 84%, and valid

measurements for at least two lumbar

vertebrae [required for calculating T or

Z scores according to International

Society for Clinical Densitometry

(ISCD) guidelines (5)] were obtained

from 12,865, or 86%. Valid

measurements for all four lumbar

vertebrae, which are required to

calculate data for the total lumbar spine,

were obtained from 11,636, or 77%.

DXA Component

DXA scans were acquired with a

Hologic QDR 4500A fan-beam

densitometer (Hologic, Inc., Bedford,

Massachusetts). Hologic software

version 8.26:a3* was used to acquire all

scans through mid-2005. In 2005, the

acquisition software was updated to

Hologic Discovery v12.4. 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

(11,12). Data provided by DXA scans

include BMD, bone mineral content

(BMC), and bone area. DXA scans of

the proximal femur provided data for

the femur neck, trochanter,

intertrochanter, Ward’s triangle, and total

femur. DXA scans of the lumbar spine

provided data for each lumbar vertebra

separately (L1, L2, L3, and L4) as well

as for the total lumbar spine (L1–L4).

All femur scans were analyzed with

Hologic Discovery software version

12.1. All spine scans acquired in

2005–2006 and 2007–2008 were first

analyzed with Hologic Discovery v12.4,

then reanalyzed with Hologic APEX

v3.0 software, which has been shown to

have better precision for the spine (13).

Comparisons of total spine BMD from

each software version were made for the

total sample and by age groups, race

and ethnicity, and gender. Mean

differences in BMD for 2005–2006 and

2007–2008 ranged from 0.00045 for

‘‘other’’ race and ethnicity to 0.00518

for participants aged 60 and over.

Simple kappa statistics for BMD ranged

from 0.9622 for participants aged 50–59

to 0.9899 for those aged 8–49. There

were no differences between the two

software versions in the percentages of

participants in the total sample with

BMD values plus or minus (+/–) three

standard deviations (SD) from the mean

BMD for the total sample. Differences

in the percentages with BMD values +/–

3 SD from the mean in subgroups were

seen, but they were not consistent across

the two software versions; that is, for

some subgroups the Discovery version

produced higher percentages of +/– 3

SD and for other subgroups the APEX

software produced higher percentages.

APEX results are used in this report.

A high level of quality control was

maintained throughout the data

collection period. In order to ensure that

data collected in the three MECs used

could be pooled for analysis, a rigorous

quality control program was used to

provide cross-calibration and

longitudinal monitoring (11,12). The

Hologic Anthropomorphic Spine

Phantom that traveled with each MEC

was scanned daily, as required by the

manufacturer, to ensure accurate

calibration of the densitometer and to

correct for any longitudinal scannerrelated changes in participant data. A

single Hologic Spine and single Hologic

Block Phantom were also circulated

among the MECs and were scanned at

the start of operations at each survey

site; this provided additional data for

use in longitudinal monitoring and

cross-calibration. The University of

California, San Francisco (UCSF), used

the Cumulative Statistics method, or

CUSUM, and MEC-specific phantom

data to identify any breaks in the

calibration of the densitometers over the

course of the survey (14). However,

there were no break points in the spine

phantom data for any of the three MECs

during 2005–2008, and, therefore, no

corrections to the participant spine data

were needed. Likewise, comparison of

data for the spine and block phantoms

that circulated among the MECs

indicated no statistically significant

differences, so that data from the three

MECs could be combined.

Technologist acquisition

performance was monitored through

in-person observations in the field and

subsequent 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

UCSF Department of Radiology using

standard radiologic techniques and

study-specific protocols developed for

NHANES. UCSF reviewers applied

invalidity codes to participant lumbar

spine or proximal femur scans that

could not be analyzed accurately.

Reasons for invalid subregions included:

1.	 Jewelry and other objects not

removed.

2.	 Nonremovable objects (prostheses,

implants, or casts, among others).

3.	 Excessive X-ray ‘‘noise’’ due to

truncal adiposity, which interfered

with the ability to obtain valid

measurements.

4.	 Arm or leg overlap.

5.	 Body parts outside the scan field.

6.	 Positioning problems.

7.	 Participant motion.

8.	 Other reasons (missing limbs,

unknown artifacts, vertebral or

proximal femoral fracture, or

panniculus).

Invalidity codes were applied to each

lumbar vertebra. If one or more

vertebrae were coded as invalid, data for

the total spine (L1–L4) were also coded

as invalid; however, data for valid

individual vertebrae were retained. In

the case of the proximal femur, all

femur subregions had to be valid in

order for data to be retained for any of

the subregions, consistent with the

approach used for DXA data for the

proximal femur in NHANES III

(1988–1994) (15).

Statistical Analysis

In this report, BMD, BMC, and

bone area data are presented for each

lumbar vertebra and proximal femur

subregion, as well as for total lumbar

spine and total femur, by age, gender,

and race and ethnicity. In addition, these

data are provided for 10 combinations

of two or three lumbar vertebrae (L1,

L2; L1, L3; L1, L4; L2, L3; L2, L4; L3,

L4; L1, L2, L3; L1, L2, L4; L1, L3, L4;

and L2, L3, L4). Data analyses were

performed using the statistical packages

SAS version 9.2 (SAS Institute, Cary,

North Carolina) and SUDAAN version

10.0 (RTI International, Research

Triangle Park, North Carolina) or with

the R survey package (University of

Washington, Seattle, Washington) (16).

Variance estimates were estimated by

Taylor Series Linearization (17,18), a

method that incorporates the sample

weights and accounts for the complex

NHANES sample design. Sample

weights calculated for examined

respondents were applied to the data to

account for differential probabilities of

selection, nonresponse, and

noncoverage. Estimates based on less

than 12 degrees of freedom or with a

relative standard error (RSE) greater

than 30% were considered statistically

unreliable (17,18). RSE is defined as the

ratio of the standard error of the

estimate divided by the estimate

multiplied by 100. In the tables,

estimates based on less than 12 degrees

of freedom or with an RSE between

30% and 39% are identified with an

asterisk (*). Estimates with an RSE

greater than 40% or whose standard

errors were not able to be calculated

using SUDAAN due to small cell sizes

were omitted from the tables. Means,

standard deviations, and percentiles were

calculated using SUDAAN PROC

DESCRIPT. Means calculated for adults

aged 20 and over were age adjusted to

the 2000 U.S. standard population to

facilitate comparisons between the sex

and racial and ethnic subgroups (19).

To provide a detailed description of

nonresponse to the lumbar spine scans,

demographic characteristics of two

groups of persons with missing lumbar

spine data were examined: 1) scanned

persons with one or more invalid

vertebrae, because these individuals lack

data for the total lumbar spine, which is

commonly used to describe spine status

in research studies; and 2) scanned

persons with more than two invalid

vertebrae, because ISCD clinical

guidelines allow assessment of spine

skeletal status via T and Z scores with

valid data from a minimum of two

lumbar vertebrae.

Total lumbar spine, femur neck, and

total proximal femur 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 that employ complex designs

(16). The femur neck was chosen

because it has been proposed as the

reference skeletal site for defining

osteoporosis in epidemiological studies

(1), while the total proximal femur was

used for the osteoporosis objective in

Healthy People 2010 (20). The total

lumbar spine was chosen because it is

frequently used to describe spine status

in epidemiological studies. Previous

analyses found that a relatively high

level of missing data occurred in the

older age groups for the total lumbar

spine due to invalid data for at least one

lumbar vertebra (21). Despite this,

previous analyses indicate that total

lumbar spine data can be used to portray

demographic patterns for the lumbar

spine in older persons (21). Specifically,

results for those over age 50 were found

to be similar in persons with no invalid

vertebra (and thus having valid total

lumbar spine data) compared with those

having two or more valid vertebrae (21).

Multiple regression (SUDAAN

PROC REGRESS) was used to assess

whether significant age × sex or age ×

race and ethnicity interactions in BMD

levels existed and to calculate mean

total lumbar spine BMD and femur neck

BMD after adjusting for age, sex, and

race and ethnicity. Interactions were

tested separately by detailed age

category for respondents under age 20

(age groups 8–11, 12–15, and 16–19)

compared with those aged 20 and over

(in decades) in order to reflect the

biological differences in bone changes

by age (bone growth in childhood and

adolescence, maintenance of bone

during adulthood, and bone loss with

aging). If no significant interaction with

age was observed, data were combined

for ages 8–19 or ages 20 and over when

calculating means by sex or race and

ethnicity. Differences in mean BMD by

sex and race and ethnicity by age were

tested using F tests from multiple

regression and were summarized by

calculating the percent difference in

adjusted means as:

Percent difference = ((Meanselected comparison group

– Meanreference group)/Meanreference group) × 100

Non-Hispanic white persons were

chosen as the reference group for all

race and ethnicity comparisons, and

males were chosen as the reference

group for comparisons by sex. Use of

terms such as ‘‘higher,’’ ‘‘lower,’’ and

‘‘greater’’ when describing differences in

mean BMD between groups indicates

that they differed statistically (p < 0.05).

mean BMD of the groups being

compared was not statistically

significant.

Patterns in BMC by age, sex, and

race and ethnicity were also examined

for respondents under age 20, because

BMC is frequently used in

epidemiological studies of children and

adolescents. However, conclusions were

the same as for BMD, so only BMD

results are shown.

Key Findings

Means, standard deviations, and

percentiles for BMD, BMC, and bone

area of the lumbar spine and proximal

femur are presented in Tables 1–60 for

persons aged 8 and over. Information

regarding invalid scan data is shown in

Figures 1 and 2. Patterns in total lumbar

spine and femur neck BMD by age, sex,

and race and ethnicity are summarized

in Figures 3–9.

for age (Figure 1). However, after

adjusting for sex and race and

ethnicity, the percentage with more

than two invalid vertebrae increased

significantly with age (Figure 1),

ranging from less than 1% in the

youngest age group to 15% in the

oldest age group. Similar patterns by

age, sex, and race and ethnicity

were seen among those with invalid

data for more than one vertebra

(e.g., missing total lumbar spine

data) (data not shown).

+	 In NHANES 2005–2008, 13,193

survey participants received DXA

scans of the proximal femur. Of

these, 4% (n = 600) were missing

data for the proximal femur due to

invalid data. The percentage with

invalid data for the proximal femur

increased significantly with age

(Figure 2) and differed by sex

(females more than males) and race

and ethnicity (non-Hispanic black

persons more than non-Hispanic

white and Mexican-American

persons).

Invalid Scan Results

+	 In NHANES 2005–2008, 13,106

survey participants received DXA

scans of the lumbar spine. Eleven

percent (n = 1,470) of those who

received a spine scan had invalid

data for at least one lumbar vertebra,

and thus did not have data for the

total lumbar spine. Most of these

had invalid data for a single vertebra

(6%). The percentage with invalid

data for individual vertebrae among

those who received a lumbar spine

scan was 4% for L1, 4% for L2, 5%

for L3, and 7% for L4. Three

percent had invalid data for two of

the four vertebrae, 1% had invalid

data for three of the four vertebrae,

and 1% had invalid data for all four

vertebrae.

+	 Two percent (n = 241) of scanned

survey participants had invalid data

for more than two vertebrae, and

thus could not have valid T or Z

scores calculated. No differences by

sex or race and ethnicity were seen

in the percentage with more than

two invalid vertebrae after adjusting
