3. A growing crisis—Agenda today
• How significant is the problem……..
• National data …Regional figures
• When does this all begin…..
• Is parental attitude a cause for concern

6. Obesity & Life style diseases
……Importance for adolescent age
• Adolescent physicians and pediatricians have
an important role in the prevention and control
of the ‘epidemic.’ of Life style disorders
• As they begin in childhood (or even earlier, in
fetal life), and Manifest due to interactions &
accumulation of various risk factors,
throughout the life cycle.

7. What is obesity ????
OBESITY is defined as a 20 % excess of calculated ideal
weight for age ,sex and height of a child. It is
associated with excess accumulation of fat in
subcutaneous tissues & other organs of body.
8. Criteria for Chilhdhood obesity
• Weight to height charts
Obese if wt 20% more over recommended.
• Body fat percentage
Boys > 25% body fat
Girls > 31% body fat
• Body mass index(BMI)
Reliable indicator of body fat. Most popular.
Measures weight relative to height.
Inexpensive, easy to perform, age & sex specific
9. Body mass index(BMI)
• Measure height of child to nearest centimeter.
• Weigh the child to nearest decimal faction in kg.
BMI == Weight in kg/ (Height in meters)x2
Plot the BMI on BMI for age /sex percentile chart
Weight status category Percentile range
Underweight <5%
Normal 5-85%
Overweight 85-95%
Obese > 95%
10. Interpretation of BMI
• BMI is a screening tool not a diagnostic one…
Heavy child may have high BMI for age . To determine if
he is obese a few more tests are reqd.
• Age & sex specific for children & teens.
Amount of body fat changes with age.
Body fat quantum differs between boys & girls.
BMI age percentile chart for boys & girls is an accurate tool
12. Causes of childhood obesity
There are two major and basic causes of obesity:
* Too many calories in
* Too few calories out
13. Phases in evolution of obesity
• Role of Intrauterine growth pattern
• Relationship between birth weight & Future BMI.
• Insulin resistance ….LBW & obesity.
• Consistently protective role of breast feeding .
• Early menarche predisposes to obesity
• 80% obese adolescents will become obese adults.
14. Barker’s Hypothesis FOAD 1986
• Fetal origins of adult-onset diseases (FOAD)
• Under nutrition and unfavorable intrauterine
environment at critical periods in early life can cause
permanent changes (in both structure and function)
in developing systems of the fetus (i.e.
programming).
• May manifest as disease over a period of time due to
`dysadaptation’ with changed environmental
circumstances

16. Characteristics of obesity in India
• Frank obesity not as high as in the West
But body composition & metabolism of Indians
(asians in general) make them especially prone to
‘adiposity’ (fat content in the body) and its
consequences.
• South Asians have at least 3 to 5% higher body fat
for the same BMI as compared to Caucasians.
• The fat is typically located ‘centrally’ (i.e. waist,
trunk) and around visceral organs - metabolically
more dangerous than peripheral fat.
17. Indian cohort studies –pune -1
• Deleterious effects of accelerated weight gain in
childhood i.e. ‘crossing of centiles’ especially in LBW
babies.
• Indices of insulin resistance and CV risk factors were
found to be highest in those that were born `small’
but were big by 8 years even though they were not
obese in absolute terms.
• Accelerated growth in childhood is associated with
early puberty and greater risk of obesity.
Bavdekar A, Yajnik CS, Caroline HD, Bapat S, Pandit A, Deshpande V., et al. Insulin resistance syndrome in 8-year-
old Indian children – Small at birth, big at 8 years, or both ? Diabetes 1999; 48: 2422 – 2429.
18. Indian cohort studies –pune -2
Maternal Nutritional Studies have shown convincingly that this
high risk body composition is present even at birth,
i.e. lower birth weight, lower muscle mass but relatively
high fat mass and hyper insulinemia (`thin fat’
phenotype)
• It is possible that such fat offers survival benefits to
newborns but also endangers predisposition to insulin
resistance from birth itself.

the thin-fat Indian baby. The Pune Maternal Nutrition Study. Int J Obes 2003;27:173-180.
19. “ Thin-fat “ baby
• Newborns, even relatively small at birth (BW <
2.9 kg) reported to have greater subscapular
skin fold thickness, which is shown to correlate
well with truncal obesity
• Also been shown that this adiposity tracks to 4
years of age

21. Increased eating
• 10 calories extra per day can result in ½ kg
weight gain per year.
• 150 calories extra per day== 7 kg per year.
• Cut out one cookie per day to lose those 7
kgs in year,.
28. Trans fat
• French fries
• Samosa kachori
• Cookies & cakes
• Ice creams/Souffles
• Wafers/Chips/kurkure

32. How media trick children’s taste buds
Wrapping affects their preferences.
Even carrots,milk & apple juice tasted better.
Kids see Mc-Donalds label and start salivating.
33. Parental misconception
• Chubby child is considered a healthy child.
• To keep a child in that state ….It is essential to overfeed.
• Mother is the Meal-planner of a baby’s diet.
• Even educated parents lack practical knowledge.
• Wide gap between nutrition Knowledge & behaviour.
• Indian snacks are considered healthy.
• Junk food provides respite from healthy food planning.
34. What’s our Dilemma & Role ?
“My child is not fat but big boned.”
“He hardly eats…….only one dry chapati & sabzi….”
Reject these notions in a firm yet subtle manner
OUR ROLE
• To Educate,Educate & Educate.
One at a time.
Children
Adults
35. Treatment of childhood obesity
Treatment depends upon the age & associated problems.
* Below 7 years;
Goal is to maintain weight than weight loss.
Allows the child to add inches not kilograms.
* Above 7 years
Weight loss is recommended at a rate of 1kg/mon
36. 5 2 1 0
Every day
• 5 or more fruits & vegetables
• 2 hours or less recreational screen time*
• 1 hour or more of physical activity
• 0 sugary drinks, more water & low fat milk
* Keep TV computer out of bed room. No screen time
under age of 2 years.
38. Prevalance of obesity in India
School children in Chennai
• > 22% HSE group
• 15% from MSE groups .
• only 4.5% from LSE group
urban well-off children : highest risk .

Prevalence ranges from 6 to 8% and occasionally higher but clubbed to mean overweight
and obesity collectively. On a more positive note, tendency for overweight is more
Urban Delhi, >25% of adult males and 47% of adult females were
found to be overweight or obese.

41. Where do parents begin
• Remember it took time for our children to gain
weight , and it will take time for them to lose
weight.
• Aim for small steps to begin the process.
42. MONITORING AND COUNSELLING THE ADOL
• Most FOAD related disorders can be prevented or
effectively managed if picked up early in life.
• Main focus of preventive programmes should be directed
towards prevention of obesity throughout childhood and
adolescence.
• Public health campaign directed towards life style changes
in the family / society as a whole.
• Benefits of healthy eating, increased physical activity &
reduction in sedentary activities have to be inculcated
from early age.
• School based programmes most likely to be successful but
health authorities and media have an important role to
play to spread awareness.

44. Identify a role model for your child
amongst your friends……….
45. Common causes of decreased physical activity
• Increased concerns of safety issues outdoors.
• Increased TV viewing, Computer use, video game playing.
• Reduced physical education and recess in school.
• Over-scheduling so family life is disrupted.
• Decreased family activity time together.
46.
47. Indian cohort studies-delhi
• An increase of BMI of 1 SD from 2 to 12 years of age,
• increased the odds ratio for disease (IGT / DM) by
1.36. in young adults
• It is now evident that our traditional understanding of
concepts of `catch up growth’ in childhood, and
‘healthy’ weight gain during adolescence may need
redefining.

49. Activity history
• Ability to walk or ride a bike to school.
• Time in play.
• Schools curriculum.
• After school and weekend activity.
• Activity of both parent.
• Screen & media time.
50. Dietary history
• Caretakers who feed the child.( Maid or grandparents)
• Food diary
High calorie foods that are low in nutritional value
Fast foods /Ready to eat snacks
Intake of juices sodas & sports drinks
Milk intake ( Formula,buffaloes)
52. There are many ways to celebrate at
school
• Non food ways ( Active game chosen, visit to a
factory, community service at orphanage).
• Healthy snacks ( fruit tray/smoothie,Idli,Kathi rolls).
• Healthy non sugar drinks ( Lemonade, lassi,Ice tea).
Unfortunately parents offer the stiffest resistance
53. Additional features associated with Metabolic Syndrome
Insulin resistance (fasting insulin, HOMA IR)
•Dyslipidemia (in addition to above, increased small dense LDL)
•Hypercoagulability of blood (increased plasminogen activator
inhibitor)
•Vascular dysregulation (beyond elevated blood pressure)

Misra et al 2008
Unpublished data
59.
60. Genetic factors or family history
• Adoption studies found a high correlation between
obesity in adopted children & their biologic parents.
• Twins reared together or apart have similar rates of
obesity.
• Having two obese parents increases a childs risk of
obesity up to 80%.
• Genetics a rare cause ,environment the culprit .
61. I Don’t Want to Grow Up
• 25% of children who are obese at age 6 will
be obese as an adult
• 75% of children who are obese at age 12 will
be obese as an adult
62. Social Difficulties
• Obese children…
– are stereotyped as “unhealthy, academically
unsuccessful & lazy”
– may be teased or verbally abused by other
children
– can become excluded from being a part of social
groups and/or other activities
63. Social Difficulties
• Obese children…
– are stereotyped as “unhealthy, academically
unsuccessful & lazy”
– may be teased or verbally abused by other
children
– can become excluded from being a part of social
groups and/or other activities
64. People who are obese or overweight also have
a lower life expectancy
A 40-year-old nonsmoking male who is overweight will lose 3.1 years of life
expectancy; one who is obese will lose 5.8 years. A 40-year-old overweight
nonsmoking female will lose 3.3 years of life expectancy; one who is obese will
lose 7.1 years.
65. How to Tell If Your Child is
Overweight or Obese
66. Indicators
• Growth Chart
– height and weight can be compared and plotted
• Skin fold thickness
– measured at the triceps with a caliper that pinches the skin and
together and will be higher in obese children
• BMI (Body Mass Index)
– is best measurement to take because it is age and gender specific
67. What is BMI?
• BMI is used to identify overweight and obesity
in children
• BMI = weight (kg)/height (m)²
• For children, BMI is age and gender specific
and is consistent with adult index, so it can be
used continuously from two years of age to
adulthood
68. Are you at risk?
• The Center for Disease Control avoids using
the word “obesity” for children
• Instead they suggest two levels of
overweight:
1.) 85th percentile: At-risk level (overweight)
2.) 95th percentile: Severe-level (obesity)
69. What does the 95th percentile BMI score mean?
• Correlates to BMI score of 30, which is the marker for obesity
in adults
• Indication for children and adolescents to have an in-depth
medical assessment
• Identifies children that are likely to have obesity persist into
adulthood
• Is associated with elevated blood pressure and lipid in older
adolescents which increases risk of diseases
71. The Family Atmosphere
• According to the American
Obesity Association, parents are
the most important role models
for children.
• Obesity tends to run in families
– Eating patterns play a role
• Children of active parents are six
times more likely to be physically
active than kids whose parents
are sedentary
72. Television & Nutrition
• Commercials feature many junk foods that
promote weight gain
– fast food, soft drinks, sweets and sugar-sweetened
breakfast cereals
• Children seem to passively consume excessive
amounts of energy-dense foods while
watching TV
73. The typical American child spends about 44.5
hours per week using media outside of school.
74. Pick-up or Delivery?
• Today, families eat fewer meals together and
fewer meals at home
– Children tend to eat more food when meals are
eaten at a restaurant
– Plenty of children eat fast food on a regular basis
– Take-out food like pizza or chinese is also popular
75. Between 1977 and 1996, portion sizes grew in the U.S., not only
at fast-food outlets but also in homes and restaurants
• One study of portion sizes for
typical items showed that:
– Salty snacks increased from 132
calories to 225 calories
– Soft drinks increased from 144
calories to 193 calories
– French fries increased from 188
calories to 256 calories
– Hamburgers increased from 389
calories to 486 calories
76. Vending Machines
• Soda
– each 12-oz (though now most are 20-oz) sugared
soft drink consumed daily increases a child’s risk
of obesity by 60%
– risk of lack of calcium if students choose
sweetened drinks with no nutritional value
instead of milk, a good source of vitamins,
minerals and protein
77. In 1977-78, drank about four times as much milk as soda. In 2001-
02, they drank about the same amounts of milk and soda
79. Keys to Preventing Obesity
• Teaching healthy behaviors at a young age is
important since change becomes more
difficult with age
• Education in physical activity and nutrition are
the cornerstones of preventing childhood
obesity
• Schools and families are the two most critical
links to decreasing the prevalence of
childhood obesity
80. Parent’s role in Prevention
Create an active environment
Limit amount of TV watching
Plan active family trips such as hiking or skiing
Enroll children in a structured activity that they enjoy
81. Parent’s role (cont.)
• Create a healthy eating environment
– Implement the same healthy diet for entire family,
not just selected individuals
– Avoid using food as a reward or the lack of food as
a punishment
– Encourage kids to “eat their colors;”
(food bland in color often lack nutrients)
– Don’t cut out treats all together, think in
moderation, or kids will indulge
82. Schools Are Only Exercising Our Minds
• According to the Center for Disease Control
and Prevention:
– Nationwide, approximately 56% of high school
students were enrolled in a physical education
class and only 29% attended PE class daily (1999)
83. What Should Schools Revise?
• POLICY
– Schools should establish policies that require daily
physical education and comprehensive health
education in grades K-12
– Schools and government should provide adequate
funding, equipment, and supervision for programs
that meet needs of all students
85. Get moving
• Exercise regularly. Get active together as a family.
• Encourage children to enjoy physical activity that
burns calories & uses different muscles.
• Find fun ways to be active inside & outside house.
• Practice sports at home.
• Involve your child in a carwash, shifting the
furniture etc.
• Start in small steps, 10 mins and build to 60 mins.
86. Ways to encourage better eating
habits for your child
• Offer kid size servings.
• Only milk at breakfast is poor choice……offer something
filling eg parantha, fruit,idli/dosa,halwa ,corn flakes….
• Encourage drinking low fat milk & water.
• Plan evening snacks esp for after play hunger pangs.
• Avoid skipping meals.
• Put in that extra effort to prepare a snack than offer cookies.
87. Help your child become more active
• Boundaries-set time limits on TV/Computers/games..for all
family members
• Play- Encourage daily activity..ride a bike,toss a ball, walk a dog.
• Family time- adopt a life style to involve children…after dinner
walk, car wash, shifting of furnitures etc.
• Encourage-provide opportunities to choose activities like hiking
photography, gardening etc.
• Enjoy- Make sure the activity is not viewed as a punishment.
88. Families need your education and
support to experience success
• Prioritize need for change in family functioning.
• Acquire skills & knowledge to effect changes.
• Set realistic goals.
89. Education
• Model good habits
• Healthy foods
Child’s ideas ….. Respect his likes & dislikes
Make them palatable… Offer alternatives
Portion size & serving size… Use hands
Small steps
Exercise & activity
Mutually agreeable changes with parents.
Make changes a family affair.
90. How to be perfect role model …
• Never skip meals…infact indulge in healthy snacking.
• Limit junk food in the house.
• Eat & prepare food with your children.
• Try new foods but never force your child to try them.
• Turn off the TV while eating.
• Be active yourself & involve the child .
91. Common misconceptions
• My child & I deserve blame for his weight problem.
• My child will lose those extra pounds….Baby fat.
• He seems overweight but then we all are big boned.
• Because he is heavy ….Needs to eat to stay healthy.
• My child’s weight problem needs a quick fix.
92.
93. How can food marketing contribute….
• The food industry creates and promotes
products that children enjoy
eating……….
• Why not create food that children like
but which is lower in sugar,salt and
fat….
• And use Shahrukh khans & Tendulkars
to model a health lifestyle & promote
healthy food products……
95. Small steps to healthier living
A journey of a thousand miles
begins with a single first step.
Chinese proverb
96. An ounce of prevention is worth a
pound of cure
• Prevention is the key strategy for current epidemic.
Primary prevention & Secondary prevention
• Priority population for intervention
Weight loss in adults difficult.
Greater number of interventions for children.
• Effectiveness of prevention methods.
Focus on reducing inactivity & encouraging free play.
Forced exercise & reduced food intake difficult.
97. Are you a role model for your child !
Behaviour is learned from observation…Good or bad
Please ask yourself following……
Do you snack all day long?
Do you eat in front of the TV?
Do you eat when you are bored or stressed ?
Do you eat dessert at every meal ?
Do you skip breakfast ?
Do you have soda/juice with your meals ?
Do you diet all the time and have a fear of food
?
98. Parting words
• Do not become discouraged. Become involved ,
and be a good role model.
• Remember small steps have enormous benefits:
Decrease 100 cals a day & increase physical
activity to burn 100 cals a day to lose weight
healthfully.
• Children can and do succeed at changing lifestyles.
99. Co-morbidities with Obesity
• Diabetes
• Hypertension METABOLIC SYNDROME
• Dyslipidemia
• Sleep apnea
• Asthma & other breathing problems
• Early puberty or menarche
• Low self esteem & bullying
• Behaviour & learning problem
• Depression
101. Get moving
• Limit media usage to no more than 2 hours.
• Emphasize activity, not exercise.
• Find activities your child likes.
• If you want active child ,be active yourself.
• Start in small steps, 10 mins and build upto 6o mins.
102. Exercise recommendations
• Children : 60 minutes daily five days a week of
vigorous physical activity that makes them sweat.
• Adults: 30 minutes of the same five days a week.
• Key point: Find something you & your child enjoy
and schedule it right into your day.
104. Eating
• Think portions…..
• Switch it up…atta for maida, Brown bread/Rice for
white , Dosa for pizza, nimbu pani for coke…
• Offer healthy meals & snacks…frying to steaming or
baking
• Everything in moderation. Nothing bad or good
Don’t eliminate ,just reduce it.
• Involve the entire family…Have children help you
prepare a meal and eat together as a family..
• Be a good role model.
110. Prevent Obesity & overweight
• HOME Reduce time spent in front of screen.
Build physical activity into routine.
• Schools School tiffins meet nutrition standards
Provide foods that are low fat/cal/sugars
Encourage quality physical education.
• Work Opportunities for activities at work
• Community Popularize fruit/veggie servings
Control the portion size
“An ounce of prevention is worth a pound of cure”
Editor's Notes
Child hood obesity is a manmade crisis unleashed on the mankind in last two decades…. These children are examples of extreme…if we as pediatricians do not do something about it today then our future generation will be the first generation not to live as long as their parents…….
It is indeed a crisis of serious magnitude the impact of which will be unleashed in next 2-3 decades.
The regional & national data on obesity is going to shock all of you….
We are also going to trace as to when & what went wrong in last the decade or so in our diets……our activity patterns and most important of all has there been a change in our attitude towards being overweight ……
Obesity is natural consequence of overeating & sedentary lifestyles……….and its occurrence is increasing rapidly in all age groups but more so in children…..Out of 45 million obese children under 5 years of age half are scattered in cities of India……we far exceed the global prevalence in age gp 5-17 years …..at 17 % …………most recent survey from Delhi put the figures of obesity in teens to 25%.....and worse was a survey from private schools of delhi putting the figures to 34%.....which means with growing affluence every third teen is overweight…………Extremely disturbing facts …………
These figures are disturbing ……..and have produced a contrasting picture of fattening urban India & undernourished rural Bharat.
We all as Pediatrician & adolescent physician are the first contact health care professionals with children who have various risk factors predisposing them to obesity. It is our duty to apprise the parents about this life style disorder which can have disastrous consequences on their life.
Simplest definition of obesity is a body weight in excess of 20% over and above ideal for age sex & height. It is characterised by excess accumulation of fat in subcutaneous tissues .Going by this definition all children who carry extra pounds will be labeled as obese which is not true as some children have larger than average body frame………….and children have varying amount of body fat at various stages of development….
To overcome this various parameters have been devised to define obesity scientifically
They are weight to height chart which are the most common tool in our office practice
Body fat percentage as measured by sensitive equipments In adolescent boys more than 25% & more than 31% in girls is considered obese.
And lastly the most popular BODY MASS INDEX which is the most reliable indicator of body weight ………measures body weight relative to height……….inexpensive easy to perform & is age & sex specific
We all know BMI is calculated from weight of the child in KGS & height of the child in Meter using the formula weight in kg divided by square of height in Meters…..
Interpretation of BMI value in children is not as simple as in adults because heavy framed children tend to have higher BMI……besides the amount of fat changes with age & also girls tend to have higher body fat percentage …….so with these limitations BMI becomes just a screening tool & not a diagnostic one…………to overcome these WHO & CDC have provided BMI percentile charts for boys & girls where BMI number is translated into a percentile value on the basis of which categorization of weight is done ……………
However it is a simplistic statement..........in reality the problem is multifactorial and usually begins early but subtly…in early school..sometimes even with a serious medical illness…following recovery of which child is overpampered with all the food & inactivity the two major evils that start this vicious cycle of obesity……….
Research has shown that intrautereine growth pattern of growing fetus can determine the weight at birth & future BMI as an adult. Heavy baby at birth is likely to be an obese child.
In addition LBW babies show a dramatic transition to central adiposity & insulin resistance very early in life and as a result are likely to grow up to be an obese adult.
The nature & duration of breast feeding is consistently protective against obesity.
Early menarche is clearly associated with BMI greater than 85th centile & moreover normal pattern of insulin resistance during puberty is a cofactor for unnecessary weight gain…..which needs to be addressed
Fetal origin of adult diseases is an interesting hypothesis put forward by Barker in 1986 ….which postulates that unfavourable circumstances in intrauterine life can create permanent changes in both structure & function in developing systems of fetus which over a period can manifest as disease due to dysadaptation changes.
There are several substantial risk factors for childhood obesity………….the most common reason is environmental in nature………..to simply put it the child has too much to eat but very little physical activity to balance this caloric equation…………science has shown that genetics play a significant direct role in obesity as exemplified by Prader willi & bardet biedl syndrome ………..but genetics are not responsible for the current obesity epidemic since the gene pool hasn’t changed in last 30 years.This implies that genes and behaviour both may be needed for the person to be overweight………Most recent studies have documented that if one parent is obese then likelihood of having an obese child is 3 times higher & if both parents are obese then the likelihood is 10 times higher……………..Endocrinal disorders contribute to a small number of obesity cases ….
Just look at these interesting facts … almost imperceptible increase of 150 cals …in simpler words… a small piece of cake or a gulab jamun or a soft drink per day over & above ones caloric needs can result 7 kg extra weight per year……
The fat cell theory is one of the mechanisms that explains the obesity in children due to overfeeding in early years of life…the fat cells are distributed throughout the body. this depot expands either by increase in the size of fat cells or by increase in their numbers……………to begin with when energy intake is high the fat cells begin to swell……and over a period if this positive caloric balance continues ….the number also starts increasing….and this number remains fixed and cannot be lost even if weight is lost….as we all are aware that cells of human body proliferate most rapidly during the first two years of life and later at puberty..and these are the two most vulnerable periods in which a child can gain these fat cells which then are for them to keep all their life
Today with easy availability of ready to eat unhealthy foods …..children hardly like to eat home cooked fresh healthy food ……their dietary habits have changed from eating fruits veggies & whole grain preparations to caloric dense highly processed food & drinks ………..
Mc Donaldization as an apt term for this current eating trends that has made our geneartion X into evergrowing …almost bursting at seams couch potatoes………..
Sugar laden drinks are the largest source of added sugars …………and its attractive marketing results in daily consumption by almost 80% urban youth…….. Each can contains about 5-6 tsf sugars & 150 empty calories…..
And it increases the risk of obesity by 60% ………..
This is an interesting caloric comparison chart where natural home made fruit juice or packed juice contains same amout of sugar………sports drinks which are very popular also contains high sugars besides caffeine….
Water still remains the best thirst quencher……..
Our society has a portion distortion…………….which started from America 30 years back where portion that we got at Mc donalds & KFCS was 1/3rd in size as well as calories …………in simple words one outing at these outlets provides 3 times the calories as compared to a home cooked meal…………….and look what we get nutritionally in these meals ………….all trans fat
Trans fat is a popular term used for solid fats like popular DALDA vanaspathi, margarine, butter oil …………all these products have replaced thin oils, butter & ghee by the food industry……….to improve the texture flavor & shelf life of ready to eat packaged snacks……….trans fats are very high in cholestrol & other unhealthy fats ………..and are the main culprit behind todays obesity epidemic ………..
When children are seen in this exuberant energetic mood these days …………The neighourhood parks are empty as children prefer to enjoy virtual games on their Play stations
Tell me how many of you have taken your children out on a picnic in recent times……..or for that matter how many of us engage ourselves in some routine physical activity………….really gone are the days
Children 8 -18 years old spend an average of 7 hours per day on entertainment media including TV computers & video games…this keeps them fixed on couche resulting in inactivity & increased snacking ultimately transforming them into Couch potatoes…………. Infact I have noted an interesting inverse realtionship between the reducing thickness of screens of Modern TV sets & abdominal girth of our children Infact adults too….
.Studies have proven that commercial ads featuring food trick the childrens taste buds…
Attractive packaging affects their preferences…
Even carrots milk & apples juice taste better….
Kids see Mc-Donalds label & start salivating….
Cant blame them some of the best advertising brains have ganged up to invade the gullible brains of our children ……….
Everyone it seems has an opinion on obesity..some may insist that they know what causes it …or they might have a dozen suggestions to how to conquer it… …..but there are enough myths about childhood weight….and to help a child lose weight lets separate fiction from fact…………..chubby child is considered a healthy child because they believe that this extra weight will go away with time…and in an effort to keep the child in that state he /she is overfed…parents esp the mother is the meal planner of the family who inspite being well informed doesn’t make the right choices …Indian snacks as well as the international junk finds its way into their tummies making them obese ……
when parents come to us with an obese child…………..most want us to declare their child fit & not obese as they feel that the child is big boned…………..As you start to enquire about the diet ….quicky comes the reply that mera baccha to kuch khata hi nahin hai at this point & right at outset gently yet firmly reject this notion of theirs because no treatment strategy can even begin ……with this attitude…….Whats the answer to this problem ……………..simply spending time with the family may be the most important thing we can do……… Education is time consuming but can be the difference between a child that grows up to be an obese adult with multiple medical issues………. And it should be done with one child at a time……..education should include parents & in todays families the maid or caretakers too ….remember its they who are providing the meals to the child……….
Treatment for childhood obesity is based on age of the child & presence or absence of associated medical conditions………..for children below 7 years who have no other health problems the goal is to maintain weight rather than wt loss ……….this strategy allows child to gain inches in height but not pounds causing the BMI for age to drop over time……….
A serious weight loss is recommended for a child who is over 7 years and the one who has associated health issues….weight loss should be slow & steady ..anywhere from ½ kg a week to month depending upon the cooperation of child and support of parents…
2 1 0 is the magic mantra for keeping obesity at bay…. Where in 5 or more servings of fruits & vegetables is recommended…restriction of media time to 2 hours ……with daily physical activity of 1 hour & absolute no to sugary drinks ….believe me it is effective…..
In our era where children & adolescents are in desperate need of role models……one thing we can do as Pediatricians is to be role model for our patients….
Our patients may see us at MC donalds or playing tennis on weekends………The impact is diverse……….What are we doing
Lets commit to be Healthier doctors for all our patients.
When the goal is to help a child to lose weight & then maintain it …parents have to take the lead…and they must remember that it took time for our children to gain weight and it is going to take time for them to shed those extra pounds …..
They must aim for small realistic goals to begin the process……and the most important thing that parents can do is to encourage their child…… never ever criticise
It has been hypothesized that steady decline in physical activity has contributed heavily to rising obesity amongst all age groups…..Increasing concerns on safety of children in urban areas has resulted in parents preferring to keep children indoor under their watchful eye …even though that results in increased TV viewing & use of computer . In addition nonexistent physical education time & inadequate recess time contributes to Inactivity at school too……….besides pressures on both working parents leaves practically no time for the physical activity of any sorts for the entire family…..
Activity history is often we all neglect….it should begin with normal routine like ability to walk or ride a bike to school………..Time in play is important …..what kind of games…….does the child study all the time…….what is the emphasis given to PE at school……..Weekend activity …………their orientation towards outdoor sports activity or mall based junking & gaming…..Finally coming to evil screentime which is assuming importance ……….& is the core reason for this current epidemic of obesity…………
Often overlooked aspect…………Depression may present with apetite changes poor sleep hopelessness & irritability………..one should enquire about bullying……teachers have a role to play……….
Get your children moving around.anything that involves movement like car wash ….shifting of furniture….helping in kitchen or with the washing machine qualifies as physical activity. It doesn’t have to push a child to exhaustion but cause sweating…….find fun ways to be physically active inside & outside ….obese children may feel conscious in group activities….they may be encouraged to participate in fun sports at home or individual sports activities like martial arts ….wall practice for tennis….
Remember always to start in small steps of 10 mins everyday & gradually build it up to an a hour day…..
Families plead you to understand their current pattern of functioning & offer support to bring about necessary changes in it ……….rather than order a few dictatorial regimes to lose weight……. You along with your team of dieticians & PE instructors should help them acquire skills to effect these changes …………and most important of all please set them realistic small goals………..reevaluate……….appreciate the gains ……..move on………..
Ask the parents to model good habits themselves………..A parent who likes to have a coke with each meal is a strong albeit a poor role model for his child….
Involve the child in the process of food selection his likes & dislikes….you should be able to suggest health alternatives like a smoothie made of fruit for a fruit…………..kathie roll for a simple roti sabzi.
Next big thing to sort out is giant portion sizes popularised by these food MNCs………..palm is a good indicator.Teach children to use their hands.
Don’t let education be too overwhelming for ur child……encourage at least 60 mins of moderate physical activity……whatever changes are made should be mutually agereable to both parents……….All the changes suggested should be family affair………….for them to be effective
Switch on the TV and every 5 mins there will an ad featuring a Biscuit or an instant snack followed by Fizzy drinks or fat laden Ice creams……….A look at this chart reveals top 10 ads in the print media……..all to woo children and sometimes we too carried away………
In West Various researchers have taken up the matter with Multinational food chains and forced them reduce the exposure of children to ads promoting unhealthy food……….
They have been asked to create food which children like & are low in fat,sugars & salts
The same needs to be done In our country where we have Plenty of Shahrukhs & tendulkars making
Millions out of this……
At least for our children ofcourse their future generations too…
There is no standard testing in children and adolescents who are obese……..most tests are done to look for comorbidities and includes fasting glucose,insulin levels & lipid profile………LFT is warranted in extremely fat individuals with suspicion of a fatty liver or a gall bladder diease…..radiographs are reqd for children with orthopedic issues……..Hormonal studies are done in those where examination reveals some markers…….
`
An ounce…………… is ironically the perfect approach to childhood obesity…….. Most researchers and clinicians would agree that prevention could be the key strategy for controlling the current epidemic of obesity……..it could be primary prevention of overweight or secondary prevention of regaining of lost weight…….Children are often considered the priority population for intervention strategies because first the weight loss in adulthood is difficult and there are a greater number of intervention for children than for adults… Schools provide natural setting for influencing food & physical activity of children
It has also been proven beyond doubt that focussing on reducing sedentary behaviour and encouraging free play has been more effective than focussing on forced exercise or reducing food intake in preventing obese children from gaining more weight
As I come to end this talk ….our parting advise to all parents is be good role models ….Involve themselves in the task of helping their child lose weight……
Also emphasize that small steps result in enormous benefits….Reduced consumption of 100 cals a day & increased activity to burn 100 cals can surely result in weight loss
And remember that children can & do succeed at changing lifestyles
Obesity brings on a number of complications for children………Glucose intolearnce leads to type 2 diabetes … many of them also have high blood pressures & abnormal lipid profiles…………and we all know that all these are the biggest risk factors for developing an early coronary artery disease………sleep apnea can make schooling troublesome for these children….besides asthma is common among this group………once obese the child is left to face the insensitive world around him..resulting in a lot of behavioural & psychological issues……..
A critical part of weight loss esp for children is physical activity………..it not only burns calories but also build stronger bones & muscles and helps a child sleep well at night and stay alert during the day……..such habits established in childhood help adolescents to maintain healthy weights despite hormonal changes & junking …..and active children are more likely to become fit adults….
A surefire way to increase activity level is to limit the media usage to less than 2 hrs per day…..and don’t let your child eat while on media to make him or her aware of the quantity of food being consumed…..One must emphasize activity of any sorts rather than push a child into structured physical activity…the object is to get him to move & sweat out rather than get exhausted………also find out the activities that your child loves doing like car wash …or shifting of furniture………..and also if you desire an active & a fit child then be a role model……be active yourself…….and remember not to push your child to exhaustion but begin in small steps of 10 mins each…and build it upto 60 minsss….
The method for maintaining your childs current weight or losing weight are the same……your child needs to eat a healthy diet and increase his or her physical activity…………parents are the one who buy the food , cook the food and decide where the food is eaten………even small changes can make a big difference to achieve this goal
As seen earlier the world is getting obsessed with portions….. So the first step is to rethink on the portion size of each meal or snack….remember to use hands for measuring portion….
Switch it up to healthier alternatives…like..
Offer healthy meals or snacks to tide over in between meals hunger pangs….
Donot brand any food as good or bad..allow everything in moderation…. Don’t attempt to eliminate just reduce it….
Involve the entire family in shopping for food to stacking to preparing & finally consuming & enjoying it as one happy healthy family.
