I DARE YOU
Daniel E. Hale, MDProfessor of Pediatrics
Chief, Division of Pediatric Endocrinology and DiabetesUniversity of Texas Health Science Center at San Antonio
Five things to share with families
when you see an overweight child
(or an overweight parent).
I DARE YOU1. Turn off the
television2. Children walk (run,
bike, hike, swim)3. Water/low fat milk
are the only beverages at home
4. Fast food is a 1 time per week treat
5. Fruits and vegetables are the only snacks
After the dare, Morton was never again seen in school
How many hours of TV does the typical American child watch?
A. 1 hourB. 2 hoursC. 3 hoursD. 4 hours
Turn Off the Television - 1• Children spend ~4 hours a day
watching television, DVDs and videos.
• 68% of 8- to 18-year-olds have a TV in their bedroom; 54% have a DVD/VCR player, 37% have cable/satellite TV, and 20% have premium channels.
• In 63% of households, the TV is "usually" on during meals.
Roberts DF, Foehr UG, Rideout V. Generation M: media in the lives of 8-18 year-olds. Kaiser Family Foundation. March 2005
Turn Off the Television - 2
• In 53% of households of 7th- to 12th-graders, there are no rules about TV watching.
• In 51% of households, the TV is on "most" of the time.
• Kids with a TV in their bedroom spend an ~1.5 hours more per day watching TV than kids without a TV in the bedroom.
Turn Off the Television - 3
• TV viewing is replacing preferred activities in a childhood (like playing, reading, doing homework or chores).
• Kids who spend more time watching TV (both with and without parent and siblings present) spend less time interacting with family members.

Turn Off the Television - 4
• Excessive TV viewing contributes to poor grades, sleep problems, behavior problems, obesity, and risky behavior.
• Children' s programming may not teach what parents say they want their children to learn; shows are filled with stereotypes, violent solutions to problems, and mean behavior.
• On average, children see ~22,000 TV commercials each year. This includes many ads for unhealthy snack foods and drinks.
American Academy of Pediatrics. Television—what children see and learn. Available at: http://www.aap.org
Turn Off the Television - 5• Being awake with the TV on for >2hr/day is a
risk factor for being overweight at ages 3 and 4 ½ years.
• Weekend TV viewing in early childhood affects body mass index in adulthood.
• The best predictors for being overweight among 3- to 7-year-olds, are physical activity and TV viewing. TV was a bigger factor than diet. Inactivity and TV became stronger predictors as the children aged.

Television viewing in early childhood predicts adult body mass index. J Pediatr. 2005 Oct;147(4):429-35. Jago R, Baranowski T, Baranowski JC, Thompson D, Greaves KA. BMI from 3-6 y of age is predicted by TV viewing and physical activity, not diet. Int J Obes (Lond). 2005 Jun;29(6):557-64.
Turn Off the Television - 6
• Children who watch TV are more likely to be inactive and tend to snack while watching TV.
• Two-thirds of the 20,000 TV ads an average child sees each year are for food; most are for high-sugar foods.
• All television shows replace physical activity. • While watching TV, the metabolic rate often goes even
lower than during rest.
Klesges RC, Shelton ML, Klesges LM. Effects of television on metabolic rate: potential implications for childhood obesity. Pediatrics 91:281-6, 1991.
McGinnis JM, Gootman JA, Kraak VI, eds. Food marketing to children and youth: threat or opportunity? Washington, D.C.: National Academy Press; 2006.
Turn Off the Television - 7• The food and beverage industry targets
children with their television marketing, which may include commercials, product placement, and character licensing. Most of the products pushed on kids are high in total calories, sugars, salt, and fat, and low in nutrients.
• Recent studies have reported success in reducing excess weight gain in preadolescents by restricting TV viewing.
Caballero B. Obesity prevention in children: opportunities and challenges. Int J Obes Relat Metab Disord 28 Suppl 3:S90-5, 2004.
No Apologies Necessary (AAP Position Statement)
• Too much television can negatively affect early brain development. This is especially true at younger ages, when learning to talk and play with others is so important.
• The AAP does not recommend television for children age 2 or younger.
• For older children, the Academy recommends no more than 1 to 2 hours per day of educational, nonviolent programs
Marketing to Children
Tips For Parents (AAP)
1. Set limits 1 hour, 2 hours, only after supper and homework are completed
2. Plan your child's viewing Make TV a “conscious” choice (no passive TV watching)
3. Watch TV with your child TV in public, not private, space
4. Find the right message Does the program reflect your views/values/behaviors
5. Help your child resist commercials Ask your child about the “message” (You will be surprised)

Tips For Parents (AAP)
6. Look for quality children's videos The Coalition for Quality Children's Media http://www.cqcm.org
7. Give other options
Coloring books, family games, a walk
8. Set a good example
Turn on the TV with a purpose
9. Express your views
If you do not approve of something, talk about it with your children!

What are the US Surgeon General’s recommendations for physical activity for adults?
A. 1 hour per day, 6 days per weekB. 1 hour per day, 3 days per weekC. 20 minutes per day, 6 days per
weekD. 40 minutes per day, 7 days per
week
Walk - 1• During the 7 days pre-survey, 77% of
children aged 9-13 participated in free-time physical activity, and 39% participated in organized physical activity.
• 36% of high school students had participated in > 60 minutes per day of physical activity on ≥5 of the 7 days preceding the survey.
• Of these, 64% of high school students participated in sufficient vigorous physical activity, and 27% participated in sufficient moderate physical activity.
• Participation in physical activity declines as children get older.
Youth Behavioral Risk Survey, 2005
Walk - 2
Type of Activity Girls Boys>60 min/day (1) 27.8% 43.8%Daily PE (2) 29.0% 37.1%
i.e., the major source of physical activity for most children is at school(1) Any activity that increased heart rate and made them breathe hard some of the time for at least 60 minutes per day on 5 or more of the 7 days preceding the survey(2) Attended physical education classes 5 days in an average week when they were in school
Youth Behavioral Risk Survey, 2005
Walk - 3
• Over half (54%) of high school students (72% of 9 grade students but only 39% of 12 grade students) attended PE in 2005.
• In 2005, 45% of 9 graders but only 22% of 12 graders attended daily PE.
• Among the 54% of students who attended PE, 84% actually exercised or played sports for 20 minutes or longer during an average class.
• High school students attending PE classes daily decreased from 42% in 1991 to 25% in 1995, (stable since then).
Walk - 4
• Physical education “time” does not equal moderate to vigorous physical activity– The “HEALTHY” experience
• Mandating the time “by law” does not result in change– The California experience
Walk - 5
• Physical activity – Assessing fitness– Differing measures (by country, state)
• Analysis of data from around the world, including the US. – Approximate rate of decline in physical fitness is
about 0.5% per year since ~1980.

Walk - 6
• Parents estimate that their children get 11.5 hours of physical activity per week.
• Children and youth average 6.5 hours per week (most of which is not moderate to vigorous physical activity).
Walk- 7
• The American Heart Association recommends that children and adolescents participate in at least 60 minutes of moderate to vigorous physical activity every day.
• The Centers for Disease Control and Prevention recommend that children and youth accumulate at least 60 minutes daily of moderate to vigorous physical activity in a variety of enjoyable individual and group activities.

Water/low fat milk are the only beverages at home and school
Beverages - 1
A Math Lesson• 3500 calories = 1 pound
• An imbalance of 100 calories per day = 36,500 calories in 1 year
• 100 calories = ~8oz of most sugared beverages
• 36,500 calories = 10.4 lbs
• So forget the math and just remember that an extra 100 calories per day caloric excess each day for a year is 10 lbs (i.e., small changes can make a difference)
Beverages - 2
Average 12-19 yrs of age drinks Boys - 28 oz of soda / day

• Longitudinal study, girls, age 8 &12 at start– Fast food ≥ 2 / week vs ≤1 / week – More rapid increase in BMI over time
• Cross sectional, both sexes, ages 4 -16– Overweight – more servings of food and
beverages away for home– this correlated with the % body fat
Fast Foods - 9
Tips for parents• The best “combo” is fast food with activity (e.g., post
hike)• Avoid supersizes, doubles, etc (>500 calories beware)• Brainstorm about easy food to prepare at home (and use
the internet)• Moderation in all things/appropriate portion sizes• Start early, with yourself (parents are role models)• Offer choices, but limit them (milk or water)• Toys come from the toy store, not the restaurant• Use the websites of fast food restaurants – find those
things that < 500 calories
Snack foods – whole fruit and vegetables
Fruit and Vegetables - 1
• < 15% of elementary students eat the recommended 5 or more servings of fruits and vegetables every day.
• Average fruit and vegetable intake among 6-11 year olds is only 3.5 servings a day.
• >50% of all elementary students eat no fruit on any given day and 3/ 10 students eat <1 serving of vegetables a day.
• 1/4 of all vegetables eaten by elementary students are French fries, a high-fat, low nutrient vegetable option.
Fruits and Vegetables - 2
• 2 year olds 116
• 5 year olds 107
• Primary care provider office (well-child check-ups) , white middle class families
• 7 day diet diaries (careful instructions)
• Calculations based on USDA guidelines
Dennison, et al. J Am Coll Nutr 17:371-378 (1998)
Fruit and Vegetables - 3
Most children eat less than 1 serving of fruits, fruit juices or vegetables per day and this does not vary much by age
Energy density (Calories per gram)• High-energy-dense foods: 4-9 calories per gram
(e.g., cookies, crackers, butter, bacon)• Medium-energy-dense foods: 1.5-4 calories per
gram (e.g., bagels, dried fruits, hummus, part-skim mozzarella)
• Low-energy-dense foods: 0.0-1.5 calories per gram (e.g., most fresh fruits and vegetables, fat-free yogurt, broth-based soups)
Fruit and Vegetable - 4
• Feeling full is more likely to make a person
stop eating than the total calories consumed. – 20 participants ate as much as they wanted from food
offered to them over 5 days.– The diet alternated from low-energy-dense to high-
energy-dense foods. – The participants felt full on the low-energy-density diet
after eating just over half the calories (1570 kcal) they consumed before feeling full on the high-energy-density diet (3000 kcal).

Fruits and Vegetables - 6
• Short-term studies: Low-energy-dense foods promoted feeling full, reduced hunger, and provided fewer calories.
• Long-term studies: Low-energy-dense foods promoted moderate weight loss.
• Studies lasting longer than 6 months: Weight loss was 3X greater for people who ate foods of low energy density than for those who simply ate low-fat foods.
Yao M, Roberts SB. Dietary energy density and weight regulation. Nutr Rev 2001;59:247-58.
Fruits and Vegetables - 7
• Whole fruit is more filling (satiating).
• Whole fruit contains fiber, and juice is fiber-free.

Review* of Dietary Intervention Studies
Many studies have found that significant weight loss can occur when advice to increase the intake of fruits and vegetables is coupled with advice to reduce energy intake.
*Rolls BJ, Ello-Martin JA, Tohill BC. What can intervention studies tell us about the relationship between fruit and vegetable consumption and weight management? Nutr Reviews 2004;62:1-17.
I DARE YOU (for the child over 2)
1. Limit screen time to <2 hrs/day
2. At least 1 hr of MVPA per day
3. Water/low fat milk are beverages of choice
4. Fast food is a 1 time per week treat
5. Fruit and vegetables are the only snacks
Beginning the Discussion
• Aspirational (Teens)– What do you want to be doing 20 years from
now?
• Generational (Parents/grandparents)– Breaking the chain
• Emotional (Parents of younger children)– Making memories for your children
Your roles• Be a role model (your behaviors are noticed)
• Pay attention to activity levels, sedentary behaviors and eating habits in children (and advocate for healthy alternatives)
• Provide information on healthy eating/ physical activity to children and parents when the opportunity presents itself
• Promote sustainable behaviors in your community
Think about ……
For thousands of years, Physical activity was required for survivalEntertainment involved interaction with
other humansStarvation was the enemy most feared.
For thousands of years, Physical activity was required for survival. Entertainment involved interaction with other humans. Starvation was the enemy most feared .
In this modern age, Physical activity has been replaced by technology. Most entertainment involves interaction with a television
or a computer. Abundance is now the plague that will rob children of
their eyes and limbs.
Think About This
If you are concerned about your child’s weight (or your own weight), then here are 5
things that you can begin to change.
1. Turn off the television (& computers and play stations)
No more than 2 hours/day for kids > 2 years old
2. Children walk (run, bike, hike, swim)
At least 1 hour of vigorous physical activity
3. No sugary beverages (sodas, sports drinks, fruit juices)
Water/low fat milk are the only beverages at home
4. Fast food is a treat
1 time per week (beware of any “meal” >500 calories)
5. Healthy snacks
Fruits and vegetables (beware of everything else)
Here’s How
• Why do you want to change?
• What do you want to change?
• What are you doing now?
• How are you going to get your family involved?
• Who is going to support you (and keep you honest)?
