This document provides information on diagnosing and managing obesity. It defines obesity as excess adipose tissue that is causally related to medical illness. It lists tools for diagnosing obesity such as BMI, skin fold thickness measurements, and waist-hip ratios. Cut-offs for diagnosing obesity are provided. Behavioral and lifestyle interventions are recommended for obesity management, including diet, physical activity, controlling environments, self-monitoring, and goal setting. Pharmacotherapy is not generally recommended for adolescents. Managing family involvement, flexibility, physical activity, and maintenance are important for treatment success.
3. Obesity Diagnostic Tools
• Percentile on Growth Charts
• Body Mass Index (BMI)
• Triceps Skin fold Thickness
(TST)
• Waist-hip ratio
4. Diagnosis of Obesity
• Weight for height >120%
• Age specific growth charts
• Skin fold thickness: >85%centile for sex
and age
• Waist : >40” in males & 35” in females
• WHR : >0.8 women & 0.9 in males
5. Percentage Wt. for Ht.

6. Body Mass Index or BMI
in Adolescents
Weight in kilograms is divided by the square of
the height in meters
• Normal : 19 to 24.9 kg/m2
• Overweight : 25 - 26.9
• Obese : 27 to 29.9
• Severe Obesity : Over 30 (Over the 95th Percentile)
• Morbid Obesity : Over 40
7. Skin fold thickness
Skin thickness is an index of body fat

10. Prevalence:
The National Health and Nutrition Examination
Surveys
• 75% relative increase in obesity in adolescents
is noted since 1970
• 25% of American adolescents are identified as
being obese
• 50% increase in morbid obesity (a BMI of 30 or
more) over the past decade
• Indian studies 7-21 % prevalence
11. Factors Contributing to the Obesity Epidemic
• Increase
– in intake of regular soda drinks
– In intake of fast foods
– in portion size of fast foods
– highcarb snacks
• Decrease
– in physical activity
• Increase
– in physical inactivity (TV, video, computer time)
12.
13. Why is it important?
• WHO has declared
obesity as a “global
epidemic”
• Childhood & adolescent
obesity is a risk factor for
adult obesity “Tracking”
• Life style diseases like
NIDDM,Coronary artery
disease Hypertension,
dyslipidemia, cancers are
linked with obesity
• Psychosocial problems
14. Obesity: Complications
• Psychological
– Disturbed body image
– Poor self-image/self-esteem
– Poor family relations: scapegoat and source
of embarrassment
– Poor peer relations and social isolation
– Exclusion from activities, especially dating
– Acting out and depression
16. Overweight Screening Procedure
Screening includes evaluation for:
– Family history
– Blood pressure
– Total Cholesterol (≥ 200 mg/dl)
– Large change in BMI (≥ 2 points in previous
year)
– Concern about weight
– Smoking history
17. Family History
• Positive Family History includes history of:
– Cardiovascular Disease
– Parental hypercholesterolemia
– Hypertension
– Diabetes
– Parental Obesity
21. Underlying Medical Conditions
• Hypothyroidism
– Initiate treatment with
levothyroxin
• Cushing’s syndrome
– Identify source of excess
cortisol
– Surgically remove source of
excess ACTH or cortisol
22. Treatment Content
Diet / Nutrition Plan
Physical Activity
Controlling the environment
Self-monitoring
Goal setting and contacting
Parenting skills
Managing high-risk situations
Maintenance and relapse prevention
23. General Management Principles
Can start with weight stabilization
Eventually a 10% weight reduction
Can decrease by 500 calories/day
with low fat/high fiber diet
Set realistic goals
2% decrease in 2500 calories: 5 lb
to drop in one year (use skim milk)
24. Physical Activity
Providing and choice of activities
appears to be superior to providing
a specific exercise prescription
Recent research suggests that
reducing sedentary behaviors may
be more effective than promoting
physical activity in promoting weight
loss
25. Exercise
Exercise also plays
very vital role in
the management
of obesity.
The more exercise
one takes, greater
is the daily energy
expenditure and
more rapidly the
obesity reduces.
26. Energy expenditure in different activities
At rest 1Kcal /min
Walking, gardening 5 Kcal/ min
Cycling, swimming 7 Kcal /min
Squash, jogging, hill climbing 10 Kcal/ min
27. Benefits of exercise
• Obese people with a heavier body to
move, spend more energy for same
amount of work.
• It is valuable as a diversion from sitting
indoors and being tempted to eat.
• Exercise reduces appetite.
• After exercise the resting B.M.R. may
increase for some hours.
28. Controlling the Environment
Help reduce cues
(e.g., taking TV out of bedroom)
Limit access to high calorie foods
Encourage family activities (e.g.,
family walks)
29. Parenting Skills
Parents often need practice in general
parenting skills to implement many of the
behavioral methods including:
Being consistent
Being observant so they can reward behavior
change
Effectively using rewards
Modeling desired behavior
Limit setting (saying “no” when necessary)

34. 1. Offer a nibble tray
Toddlers like to graze their way throughToddlers like to graze their way through
a variety of foods, so why not offer them aa variety of foods, so why not offer them a
customized smorgasbord?customized smorgasbord?
Use an ice-cube tray, a
muffin tin, or a
compartmentalized
dish, and put bite-size
portions of colorful
and nutritious foods in
each section.
Call these finger foods
playful names that a
two-year-old can
appreciate
35. 2. Spread it
Toddlers like
spreading,
or more
accurately,
smearing.
Show them how to use a table knife to spread
cheese, peanut butter, and fruit concentrate
onto crackers, toast, or rice cakes.
36. What and how much they are willing to eat may vary daily.
Don't be surprised if
"The only thing consistent about children’s feeding is"The only thing consistent about children’s feeding is
inconsistency."inconsistency."
•your child eats a
heaping plateful of
food one day and
practically nothing the
next,
•adores spinach on
Tuesday and refuses it
on Thursday
• wants to feed herself
at one meal and be
totally catered to at
another.
3. Count on inconsistency
37. Toddlers
are into
toppings.
4. Top it
Putting nutritious, familiar
favorites on top of new and
less-desirable foods is a way
to broaden the finicky
toddler's menu
38. Make a smoothie – together.
Milk and fruit – along with
supplements such as juice, egg
powder, wheat germ, yogurt,
honey, and peanut butter –
can be the basis of very healthy
meals.
5. Drink it..
If your youngster would
rather drink than eat,
don't despair
So what if they are consumed through a straw?
One note of caution: Avoid any drinks with raw eggs
or you'll risk salmonella poisoning.
39. How much a child will eat often depends on
how you cut it.
6. Cut it up
Cut sandwiches, pancakes, waffles, etc. into
various shapes using cookie cutters.
40. 7. Package it
Our kids enjoy the unexpected and fanciful when it comes to
serving dishes – anything from plastic measuring cups to ice-
cream cones.
41. "Doctor, he won't eat his vegetables"
8. Become a veggie vendor
So if you aren't the proud parent of a veggie lover, try
the following tricks
•Plant a garden with your child.
•Slip grated or diced vegetables
into favorite foods
•Use vegetables as finger foods
and dip them in a favorite sauce
or dip.
•Concoct creative camouflages.
•Cut the vegetables into
interesting shapes (Make veggie
art).
42. 9. Share it
If your child is going
through a picky-
eater stage, invite
over a friend who is
the same age or
slightly older whom
you know “likes to
eat.”
Your child will
catch on. Group
feeding lets the
other kids set
the example.
43. 10. Respect tiny tummies
This less-is-more meal plan is not only more
successful with picky eaters, it also has the
added benefit of stabilizing blood-sugar levels,
which in turn minimizes mood swings.
Dole out small
portions at first
and refill the
plate when your
child asks for
more.
44. 11. Make it accessible
Reserve a low shelf in the
refrigerator for a variety
of your toddler's favorite
(nutritious) foods and
drinks.
This tactic also enables
children to eat when they
are hungry, an important
step in acquiring a
healthy attitude about
food.
Give your child shelf space.
45. 12. Use sit-still strategies
One reason why toddlers
don't like to sit still at the
family table is that their
feet dangle. Try sitting on
a stool while eating.
Children are likely to sit and
eat longer at a child-size
table and chair where
their feet touch the
ground.
46. 13. Turn meals upside down
The distinctions betweenThe distinctions between
breakfast, lunch, and dinnerbreakfast, lunch, and dinner
have little meaning to ahave little meaning to a
child.child.

morning or fruit and cerealmorning or fruit and cereal
in the evening, go with it –in the evening, go with it –

all.all.
This is not to say that you
should become a short-order
cook, filling lots of special
requests,
but why not let your toddler
set the menu sometimes?
47. 14. Let them cook
Let your child help
prepare the food.
Use cookie cutters to
create edible designs
out of foods.
Give your assistant
such jobs as tearing
and washing lettuce,
scrubbing potatoes,
or stirring batter.
48. 15. Make every calorie count
Offer your child foods that pack lots of nutrition into
small doses.
Nutrient-dense foods
that most children
are willing to eat
include:
•Pasta,Brown rice and
other grains,
Potatoes,Cheese,
Poultry, Eggs, Squash,
Fish, Sweet potatoes,
Kidney beans,Yogurt,
etc.
50. Flash Card Technique
• Increases motivation
• involves writing
reasons for wanting to
lose weight
• I will look better
• I will feel better
• I will be be healthier
• I will fit into my
favourite pair of jeans
51. Food Diary
Time Food Or Liquid
consumed
Place Circumstances
7.50
pm
1 pack of chips
1 piece of cake
1 cola
bedroom watching TV
• Identifies triggers
• Useful in understanding eating
patterns
• Logs exact amount of food or
liquid consumed
52. Setting diets & goals
• Identifying and sticking to
– a specific diet
– food to be consumed
– Place
– time
• Setting reasonable goals
like
– losing one or two pounds
a week likely to be
achieved
54. Ways of controlling urges
• Removal of tempting foods
• Use of distractors like engaging in
another activity
• Using positive self-statements like
I can do this, I must
control myself, I will be fine, The urge
will pass
55. Use of Reinforcement
• Positive reinforcement :
Rewarding oneself as goals are met
e.g. going for a film with a friend
• Negative reinforcement : escape
unpleasant stimulus to increase desired
behaviour > missing a favourite TV
programme if overeaten
57. Pharmacotherapy
Shown to be
effective in the
treatment of
obesity in some
adults
Their use in most
youth is limited at
this time
Teens should be
at least 16 years of
age with morbid
obesity
58. Failure of
Obesity Treatment
• Lack of family involvement and
support
• lack of flexibility
• Lack of emphasis on increasing
physical activity
• Lack of a maintenance phase
59.
60. Diets may produce weight loss but do
not cure obesity; weight regain is
common.
61. Eat less; eat 2/3 or ½ the
calories you have been eating
62. Target is to eat about 1200-2000 kcal/d,
depending on the age of the child
63. Try to cut out empty calorie foods –
fats, soft drinks, and fast foods.
64. Amounts of low calorie foods
can be increased – fruits and
vegetables
74. WHAT can we do to prevent
obesity ?
Right from childhood into
adolescence into adulthood we must
encourage
•Exercise,
•Physical activity
•Physical Fitness
•Life style modification
•Nutritional intervention
