WHY WORRY ABOUT PEDIATRIC OBESITY?: WHY WORRY ABOUT PEDIATRIC OBESITY? Pediatric obesity is of epidemic proportion.
Pediatric obesity is the most common chronic disease of childhood.
DEFINITION OF PEDIATRIC OBESITY: DEFINITION OF PEDIATRIC OBESITY Overweight / At risk of overweight
BMI 85-95%
Obese / Overweight
BMI andgt;95%

WHY WORRY ABOUT PEDIATRIC OBESITY?: WHY WORRY ABOUT PEDIATRIC OBESITY? Is pediatric obesity a real problem or just a cosmetic issue?
WHY WORRY ABOUT PEDIATRIC OBESITY?: WHY WORRY ABOUT PEDIATRIC OBESITY? Adult obesity is clearly associated with numerous health problems.
Type II DM
CAD
Hypertension
Cancer
Joint disease
Gallbladder disease
Pulmonary disease
WHY WORRY ABOUT PEDIATRIC OBESITY?: WHY WORRY ABOUT PEDIATRIC OBESITY? Significant risk of childhood obesity to persist into adulthood.

WHY WORRY ABOUT PEDIATRIC OBESITY?: WHY WORRY ABOUT PEDIATRIC OBESITY? Economic impact
The estimated cost of obesity in the US in 2002 was $117 billion.
The hospital cost of pediatric obesity is also increasing.
1979: $35 million
1999 $127 million
IMPACT OF CHILDHOOD OBEISTY IN ADULTHOOD: IMPACT OF CHILDHOOD OBEISTY IN ADULTHOOD Childhood obesity has significant adverse effects on health in adulthood
Hoffmans 1988: Dutch males, increased mortality after 32 years in obese vs. lean adolescent males.
Mossberg 1989:Swedish study, increased mortality after 40 years in obese vs nonobese children
IMPACT OF CHILDHOOD OBESITY IN ADULTHOOD: IMPACT OF CHILDHOOD OBESITY IN ADULTHOOD Harvard Growth Study:
Two fold increased all cause mortality in obese vs nonobese adolescents as adults
2 fold increase in CAD mortality
Increased risk of colon cancer in males
Increased risk of arthritis in females
The association of adverse effects on adult health may be independent of obesity in adulthood
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Psychosocial
Most common complication of pediatric obesity
Increased rates of depression
Poor self esteem
Obese adolescents negative self image may carry over into adulthood
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Societal discrimination
Obese females have lower acceptance rate at colleges than non-obese females
National Longitudinal Survey of Youth: obese adolescent females as young adults had less education, less income, higher poverty rate, decreased rate of marriage vs nonose females
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Endocrine
Non-insulin-dependent diabetes mellitus
Pinhas-Hamiel 1994

92% of these had a BMI andgt;90%
Geisinger weight management program
60% have insulin resistance
10% have fasting insulin level andgt; 100 (Nl andlt;17)
1% have type II DM

CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Hypertension
Primary hypertension uncommon in childhood
60% of children diagnosed with hypertension are obese
Use pediatric standars
Geisinger weight management program
45% have hypertension
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Hyperlipidemia
The atherosclerotic process begins in childhood.
Pediatric obesity is associated with increased cholesterol, LDL-cholesterol, triglyceride levels and lower levels of HDL-cholesterol
Geisinger weight management program
45% have hypercholesterolemia
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Hepatic steatosis
Hepatic steatosis present in 25-83% of obese children
10-15% of obese children have elevated liver enzymes: steatohepatitis or non-alcoholic fatty liver disease
Rashid: 83% of children with steatohepatitis were obese. 75% had fibrosis-cirrhosis
CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY: CHILDHOOD COMPLICATIONS OF PEDIATRIC OBESITY Orthopedic

Slide28: PEDIATRIC OBESITY IS NOT JUST A COSMETIC PROBLEM!
ETIOLOGY OF PEDIATRIC OBESITY: ETIOLOGY OF PEDIATRIC OBESITY
ETIOLOGY OF PEDIATRIC OBESITY: ETIOLOGY OF PEDIATRIC OBESITY Etiology is multifactorial
Interaction of genetics and environment
Energy imbalance
Energy In = Energy Used + Energy Stored
For every extra 100 calories consumed per day one will put on 10 pounds per year
ETIOLOGY OF OBESITY: ETIOLOGY OF OBESITY Caloric intake has increased
Eating unsupervised, lack of family meals
Eating at multiple sites
Eating out / take out food
Beverages
Calorically dense food
ETIOLOGY OF OBESITY: ETIOLOGY OF OBESITY Physical activity has decreased
Schools with less physical education
After school programs
Safety concerns
Convenience activities
Increased sedentary activities: TV, computer, video games
ETIOLOGY OF OBESITY: ETIOLOGY OF OBESITY Physical activity
TV / video games
More time spent watching TV less time for physical activity: average 2.5 hours / day, 20%andgt;5 hours / day
BMI and obesity associated with higher amount of time spent watching TV
Higher cholesterol levels associated with greater amount of time spent watching TV
40% of children 1-5 years have TV in their bedroom
TREATMENT OF PEDIATRIC OBESITY: TREATMENT OF PEDIATRIC OBESITY Weight management programs are available and can be effective
High rates of recurrence
Prevention is the key
PREVENTION: PRECONCEPTION: PREVENTION: PRECONCEPTION Prevention starts prior to conception
Obese adolescents have an 80% probability of being obese as an adult
Today's adolescents are tomorrows parents
Parents act as role models for their children
The risk of obesity in a child born to obese parents is significantly increased
Need to educate and intervene at this time to help prevent obesity is subsequent generation
PREVENTION: POST CONCEPTION: PREVENTION: POST CONCEPTION Routine prenatal care
Advocate normal weight gain during the pregnancy
LGA infants and infants of diabetic mothers have higher rates of subsequent obesity
SGA infants also at higher risk
Hediger ML et: Pediatrics104:e33, 1999
PREVENTION: POST CONCEPTION: PREVENTION: POST CONCEPTION Promote breastfeeding
Dewey 2003: 8 out of 11 studies noted a lower rate of obesity in children if breastfed vs. formula fed
Bergmann 2003: Longitudinal study of breastfed vs. formula fed infants
BMI the same at birth
BMI at 3 andamp; 6 months andgt; in formula fed vs. breastfed infants
Rate of obesity at 6 years was tripled in formula fed vs. breastfed
PREVENTION OF PEDIATRIC OBESITY: PREVENTION OF PEDIATRIC OBESITY Measure and plot BMI
Only done by 20% of primary care providers
Identify those at risk
Anticipatory guidance
Nutrition
Physical activity
Healthy lifestyles

Treatment needs to be individualized and family based
Make only a few changes at a time
TREATMENT OF PEDIATRIC OBESITY: TREATMENT OF PEDIATRIC OBESITY For a child who will not be entering the formal obesity clinic
Stage I: Limit TV, do not eat in front of the TV and decrease calories from beverages.
Stage II: Eat as a family, some increase in physical activity
Stage III: Nutrition education and initial implementation of hypocaloric diet

BARIATRIC SURGERY: BARIATRIC SURGERY Little information on pediatric bariatric surgery
May be appropriate in individual cases
Severe obesity, BMI andgt; 40
Significant co-morbidities
Unresponsive to more conventional weight loss program
BARIATRIC SURGERY: BARIATRIC SURGERY Preoperative evaluation in a pediatric weight management program
Psych evaluation
Depression
Ability to cope
Support system
Willingness to comply
BARIATRIC SURGERY: BARIATRIC SURGERY Pediatric cases should be done in a pediatric center
Prospective multi-institutional study in progress
Options:
Gastric bypass
Lap band
CONCLUSIONS: CONCLUSIONS Pediatric obesity is of epidemic proportion
The etiology of pediatric obesity is multifactorial
Pediatric obesity is associated with complications in childhood as well as adulthood
CONCLUSIONS: CONCLUSIONS Treatment of obesity is not ideal
Prevention of obesity may be a more effective means dealing with pediatric obesity
In order to have any significant impact on pediatric obesity a team approach is required: child, family/parents, community, health care providers, insurance companies, government
