• What is body image?
• What forms our personal body image?
• What body image messages come out of ads?
• What skills do people need to decode body
image messages in the media so as to not be
impacted by the unhealthy messages?
Discussion Questions:
• Why do you think there is
so much focus in our
society on body image?
• Why do we think we
should look a certain way?
• How does the ideal image of a woman's body
differ in other cultures? In other historic times?
How does this compare to the ideal image of a
man's body?
• Who controls what images we see?
Do you think teenage girls are especially
vulnerable to these ideas? Do teenage boys feel
similar pressures?

• Dove paid __________dollars
for 30 seconds
of commercial time during Superbowl XL (2006)
to launch the commercial featuring the young
girls.
• The Dove commercial is very different from
most of the commercials featured during
Superbowl broadcasts. (Typically these
commercials are light-hearted, comedic, and
rarely address social issues.)

Journal #3
• What does it mean to you when you are
encouraged to ‘stand up’?
• What are some ways you have ‘stood up’ to
bullying? What are other ways that a person can
‘stand up’?
• Instead of saying ‘stand up’, is there another way
to say ‘this’ so that the message is clearer? What
are we really trying to get people to do?
Side Note – Stand Up (Feb 24,2016)
• Pink Shirt Day - Show your support for the
Fair Treatment of Others (Stand Up)
• Wednesday, Feb 24 this week is Pink Shirt day.
Members of Social Justice will be selling pink shirts
for $7 in the main lobby at lunchtime today and
during recess and lunch times this week. Show your
support for the fair treatment of others by wearing
pink on Wednesday.
What is Pink Shirt Day? How’d it begin?
• A grade 9 boy wore a pink shirt to school – he was teased for it.
• David Shepherd, Travis Price and their teenage friends
organized a protest
• 'I learned that two people can come up with an idea, run with
it, and it can do wonders,' says Price, 17, who organized the
pink protest. ‘Finally, someone stood up for a weaker kid.’
• So, Shepherd and some others headed off to a discount store
and bought 50 pink tank tops. They sent out message to
schoolmates that night.
• As they stood in the foyer handing out the shirts, the bullied
boy walked in. His face spoke volumes. 'It looked like a huge
weight was lifted off his shoulders,' Price recalled.

Bullying is unwanted, aggressive behavior among school aged
children that involves a real or perceived power imbalance. The
behavior is repeated, or has the potential to be repeated, over
time.
If you have the courage to ‘stand up’…
do it, because a lot of people don’t ☺
• Ways to ‘Stand up’?
How do we diffuse situations of cruelty
when most of us are afraid to “stand up”
because we’re afraid of being next?
•
•
•
•
•
Don’t be part of the growing crowd
Don’t laugh
Don’t jump on board
Walk away
Follow up with the victim later to see if they’re
ok
• Tell someone who can help
Speaking up needn’t be complex.
Say…
• “That’s enough”
• “Stop it”
• “Leave her/him/them
alone”
Indicators of a healthy body weight:
• 1. Waist Circumference
• 2. Waist to Hip Ratio
• 3. Body Mass Index (BMI)
• 4. Body-Fat Percentage
• 5. Growth Chart
P. 393 in the text
Waist Circumference
Waist circumference
• common measure used to assess
abdominal fat content.
• excess body fat in
the abdomen that is out of
proportion to total body fat is
considered a predictor of risk factors
and illness associated with obesity.
Measuring Circumference
How to measure waist circumference:
• Measure the smallest area found
below the rib cage but above the
umbilicus (bellybutton).
What Waist Size is Risky?
• Risky waist circumferences differ for men
and women.
• Men at risk - waist measurement greater
than 40 inches (102 cm)
• Women at risk - waist measurement
greater than 35 inches (88 cm)
Waist-to-Hip Ratio?
• Waist-to-hip ratio (WHR) is the ratio of
a person's waist size to hip size
• mathematically calculated as the waist
size divided by the hip size.
• For most people, carrying extra weight
around their middle increases health
risks more than carrying extra weight
around their hips or thighs.
Risky Ratios
• For both men and women, a waist-to-hip
ratio of 1.0 or higher is considered "at risk"
or in the danger zone for undesirable
health consequences (i.e., heart disease).
Healthy Waist-to-Hip Ratios
• For men, a ratio of .90 or less is
considered safe.
• For women, a ratio of .80 or less is
considered safe.
What is BMI?
• BMI stands for Body Mass Index.
• Put simply, BMI is a common
measure expressing the relationship
of weight-to height.
What is My BMI?
• The Body Mass Index Formula
• A person’s BMI can be calculated
using a simple mathematical formula.
• BMI =[Weight in pounds ÷ Height in
inches ÷ Height in inches] x 703
Example BMI
A person weighing 210 pounds
and 6 feet tall would have a
BMI = 210 pounds divided by 72
inches divided by 72 inches
multiplied by 703 = 28.5
BMI and Your Health?
• A healthy BMI for adults is between 18.5 and
24.9.
• BMI ranges are based on the effect body weight
has on disease and death.
• A high BMI is predictive of death from
cardiovascular disease, diabetes, cancer, high
blood pressure and osteoarthritis
(consequences of being overweight as an adult).
• Obesity itself is a strong risk factor for premature
death.
BMI Cut points for Adults
• We interpret BMI values for
adults with one fixed number,
regardless of age or sex, using
the following guidelines:
• Underweight: BMI less than 18.5
• Overweight: BMI of 25.0 to 29.9
• Obese: BMI of 30.0 or more

body fat in relation
to muscle.
• Can be measured
by using the
skinfold measure

How to take a Skinfold Measure
• This method uses
Skinfold Calipers that
pinches the skin to
measure body fat on
various parts of the body
(thigh, tricep, abdominal
area…).
• The measurements are
then put into an equation.
• Should be completed by
a qualified professional.
