Assessing Obesity in Children
by Barbara J. Moore, PhD
In December 2007, the American Academy of
Pediatrics (AAP) published a series of
reports on the assessment,1
treatment2 and
prevention3 of childhood obesity.
These
reports were the result of extensive
research and deliberations by an expert
committee of scientists and clinicians from
15 professional organizations including the
AAP and the American Medical Association, in
collaboration with the Health Resources and
Service Administration and the Centers for
Disease Control and Prevention (CDC).
Shape Up America! offers the first in a
series of articles summarizing the expert
committee recommendations.
The assessment report1 was based
on over
300 studies published since 1995 and reviews
the issues relevant to identifying overweight
and obesity in children and adolescents.
There has been considerable confusion about
assessing weight status and whether the terms
"obese" or "overweight" should be used to
describe excess fat in children. The expert
committee states that primary care providers
should universally assess children for
obesity risk to improve early identification
of elevated body mass index (BMI), medical
risks, and unhealthy eating and physical
activity habits.4
The committee makes the following
recommendations when assessing the weight of
children:
- Because it correlates well
with body
fat, BMI should be calculated and plotted on
CDC
growth charts at least
annually. (To reduce errors, the
calculation of BMI and plotting can be done
automatically on the Shape
Up America! or CDC
Web sites.)
- Each year, height and
weight should be
accurately measured in metric units and BMI
calculated as weight in kilograms divided by
the square of height in meters.
- Because
height is squared, any errors in height will
be magnified. The expert committee prefers
measuring height in centimeters
since it offers greater precision. For those
unable to use metric units, BMI may be
calculated in pounds and inches using the
equation: wt/ht2 x 703.
- Height should be measured
in bare or
stocking feet with a wall-mounted height
stadiometer (not a platform scale with a
moveable rule on top), except in infants and
children who are unable to stand erect. These
children and infants under 2 years old should
lie supine (face up) and fully extended for
measurement of recumbent length, and 1.0 cm
should be subtracted from this value
before
BMI is calculated.
- Weight should be measured
(preferably
in kilograms) with a calibrated balance-beam
scale, with the child in light clothing and bare
or stocking feet.
Below are the new terminology and definitions
of "overweight" and "obesity" recommended by
the expert committee:
| Age of child |
Definition of Overweight |
Definition of Obese |
Comments |
Children and adolescents
2 to 18 years old
|
BMI ≥85th percentile but <95th
percentile or
BMI<30 kg/m2 (whichever is smaller).
|
BMI ≥95th percentile for BMI by age and sex
or >30 kg/m2 (whichever is smaller).
|
"At risk for overweight" should be replaced
with the term "overweight" as defined here.
The former definition of "overweight" should
be replaced with the term "obese" as defined
here.
|
|
Children 2 years old or younger
|
Weight-for-recumbent length percentiles
should be used to evaluate weight relative to
linear growth. (See CDC
growth charts.)
Children whose age- and sex-specific
weight-for-length is ≥95th percentile are
considered "overweight."
|
The term "obese" should not be used in
children this young.
|
Recumbent length is measured in this age
group and considered relative to the child's
weight and age.

Consideration of Possible
Harm
The expert committee concluded there is no
direct evidence of harm resulting from
screening for childhood overweight and
obesity.1 Although many studies have
demonstrated an array of negative social and
psychological consequences of obesity, the
committee concluded that screening would not
trigger or amplify any of these. The
committee acknowledged that the US Preventive
Services Task Force reviewed this issue in
2005 and described the level of evidence
about possible harm as
"insufficient."5
People seeking details and protocols for the
accurate measurement of height (or stature),
weight and recumbent length should consult
reference 6.

Push-Ups: A Great Exercise for Busy People
by Shelly McClellan, DPT
As a physical therapist, I am often
confronted by people with questions on how to
tone certain parts of the body. Isolated
muscle strengthening is often required to
restore balance and function in the case of
injury. To accommodate busy people,
and make the most of their time and efforts,
I like to take a broader approach and
prescribe exercises with multiple benefits.
The push up is a great exercise to do if you
are healthy and want to strengthen your upper
body or tone and improve its appearance. It
requires no equipment, very little time and,
if done consistently, will yield excellent
results.
There are many ways to complete a push-up.
Each way emphasizes a different part of the
body. We will start easy and finish with the
most challenging.
#1 Plank Position
Description: Prone (face down), arms
extended
straight, with hands contacting the floor
directly beneath the shoulders, while toes or
knees touch the floor. Hold it for as long as
you can without losing your form. (Also see
Do's and Don'ts below.)
Plank Position
#2 Partial Push-Up
Description: In plank position, with knees
and hands on the ground, slowly move your
whole body toward the floor and slowly return
to the original position. Hold it 2 seconds
at the bottom of the motion. (Also see Do's
and Don'ts below.)
Partial Push-Up
#3 Full Push-Up
Description: In the full plank
position, with
toes and hands on the ground, slowly move
your whole body toward the floor and then
slowly return to the original position. Hold
it 2 seconds at the bottom of the motion.
(Also see Do's and Don'ts below.)
Full Push-Up
For all push-ups:
Do's
Do keep your ears parallel to your
shoulders.
Keep your abdominal muscles tight and your
back flat.
Don'ts
Don't let your back sag.
Don't let your head hang forward.
These variations work your abdominal muscles
and the muscles of your shoulder girdle and
arms effectively and efficiently. To increase
the work load on your triceps (the muscle in
your upper arm that we focused on in the
April,
May
and June
issues of the
newsletter), you can vary the
position of your hands. Moving your hands
further apart makes the exercise harder. Be
sure to maintain good form at all times.

Therapy in Bozeman, MT.

My Story
The first step in losing weight is to
be ready and willing to do what it takes to
lose weight safely and healthfully. Makaila
realizes that despite the challenges and
hurtful "fat" talk that she endures, she is
ready to do something about it. We wish her
continued success in her weight loss efforts.
I'm 17 years old and I weigh about 220
pounds. Two weeks ago I was about 10 pounds
heavier. I do not look like I weigh that much
but I really do and at times I'm very
uncomfortable with myself. All my friends are
really skinny and they always talk about
their weight and how "fat" they are, which
really just makes me feel even worse about
myself because I outweigh some of them by
almost 100 lbs. But I hold my head high and
keep going because even though almost
everyone in my family is overweight and I
really love food, I am going to lose weight!!!

you! If
