This presentation provides a better understanding of the biologic REALities and impact of weight bias on pediatric obesity management. The paradigm shift in pediatric obesity management is also explored, with a review of Health At Every Size (HAES) and the use of the Edmonton Obesity Staging System to help guide management.

Managing Obesity: The REALities

Striking a Balance... Weigh in with Knowledge, Research, Practice SYMPOSIUM

September 30th 2013

The REALities: Objectives

• Biologic REALities• Psychosocial REALities• Impact of Weight Bias• Debunking Common Myths• Paradigm Shift

• Health At Every Size (HAES)

• Edmonton Obesity Staging System

• The Pediatric 5A’s

Obesity is Defined as BMI > 95th%

Limitations of BMI• Not sensitive/ specific for:

• Presence of obesity related risk factors• Health behaviours• Co-morbid conditions• Psychopathology• Global functioning• Global health• Quality of Life

Limitations of BMI

BMI= 32 kg/m2 BMI= 21 kg/m2

Obesity is….

• A sign or symptom• A disorder of energy balance

• Adaptive/ Maladaptive?

• A risk factor for disease• Modifiable through health behaviours

Obesity is not….

• A sensitive indicator of health

• A sensitive indicator of health behaviours

• A character flaw

• A lack of will power

Additional weight loss can only be achieved by a more severe diet and further increases in

physical activity

Katan B et al JAMA (2010)

Debunking Some Myths

Are Obese Kids less Active?

• No marked difference in physical activity between overweight and lean kids • Overweight and obese girls had the same minutes of

moderate to vigorous physical activity as lean girls• Overweight boys had 14 min and obese boys had 22

min less of daily activity than lean boys

Colley R et al, Health Reports (2011)

Obesity-Chronic Disease Paradox

• Overweight and moderate obesity (BMI < 35), is not associated with a decrease in life expectancy• Overweight is associated with increased longevity

• Survival advantage:• Renal Failure• Heart Failure• Type 2 Diabetes

McGee DL et al, Ann Epidemiol (2005)Curtis JP et al, Arch Int Med (2005)Beddhu S, Seminars in Dyalisis (2004)Doehner et al, Int J Cardiology (2011)

Obesity Chronic Disease Paradox

5202 patients with T2DM and pre-existing CVD:

• Lowest mortality: BMI 30-35 kg/m2• Weight loss associated with increased

total mortality, cardiovascular mortality

Doehner et al, Int J Cardiol (2011)

Abdulla J et al. Eur Heart J (2008)

Myocardial Infarction (MI)

Heart Failure (HF)

21,570 patients admitted for MI or HFAll cause mortality after 10 year follow up• BMI > 35 associated with increased

risk in MI but not HF• BMI 30-35 not associated with

increased risk

Edmonton Obesity Staging System (Kuk et al, 2011)

• New risk-stratification system that classifies adult obese individuals into 5 graded categories based on morbidity and health-risk profiles

• EOSS independently predicted increased mortality even after adjustment for common methods of classifying obesity (Padwal et al., 2011)

Sharma AM & Kushner RF. Int J Obes 2009

Sharma AM & Kushner RF. Int J Obes 2009

EOSS BMI Class

Survival Curves diverge when stratified by EOSS

score but not by BMI Class

The Psychosocial REALities

What is it like for children and youth who have a higher

BMI?

Psychosocial REALities

Overweight youth:• Are stigmatized• Are often bullied by peers• Tend to have poor body image• Tend to have lower self-confidence, self- esteem and

higher incidence of mental health problems

Puhl et al. Obesity (2009)

Storch et al. J. Pediatr. Psychol. (2007)

Bullying

• 30% of overweight girls and 25% of overweight boys experience weight focused peer victimization• 60% of the most severely overweight kids report

harassment

• 40% of youth report that obesity is the primary reason why peers are teased or bullied • 37% reported being gay or lesbian as the primary

reason• 10% reported race, ethnicity, disability, religion

Eisenberg M et al Arch Pediatr Adolesc Med (2003)Puhl RM et al, J Sch Health (2011)

Weight Bias at home

• 47% of overweight girls and 34% of overweight boys report being teased about their weight by their parents

• 72% of overweight adults reported they had experienced weight bias from family members as children

Puhl RM et al, J Sch Health (2011)Puhl RM et al, Psych Bull (2007)

Societal Pressures

• In Western Society the media is a powerful influence and pressure on youth today

• Body image messages are ever present and typically state:• Thin women are beautiful, successful and happy• Muscular, lean men are handsome and successful

Grabe et al. Psychological Bulletin (2003)

THIN, THIN, THIN

MUSCLE, MUSCLE, MUSCLE

Body Image in Youth Today

• 40-50% of girls aged 11-15 say they need to lose weight

• 61% of grade 7/8 students trying to lose weight

Canadian study: Jones et al. 2001

add stats on overweight/obese youth re:BI

Weight Based Teasing and Discrimination

Youth Often Feel

• Angry• Frustrated• Sad• Helplessness• Hopelessness• Anxious• Worried

Families Often Feel

• Guilty• Helpless• Frustrated• Tired• A desire to try and fix or “control” things• A loss of trust with the youth

The Diet Industry Culture

Familiar Claims:

“Lose weight quickly” “Reset your genetic code” “Eat all you want – Lose up to 30 pounds in 3 weeks” “Scientifically sound”, “Based on proven studies”

Private weight loss industry in the US estimated at $58.6 billion annually

(Marketdata Enterprises, 2009)

Pawlak, 2009

Mixed Messages in the Media around Food

Set Point Theory

Our bodies have a Set Point (range) it wants to stay at and would if we eat “normally”

• Our bodies are self-regulating• Think of shoe size, height and body temperature

• Set point is a range & genetically determined

• Our body works hard to keep us in the range• Altering metabolic rate

Wilmore et al. (1999)

Restraint Theory

• Research has examined eating behaviour of Dieters vs. Non-Dieters

• Laboratory studies demonstrated that Dieters are more likely to ‘overeat’ or disinhibit when exposed to:

• Stress• Emotional Cues• Food Cues

Herman & Polivy, 1985

Restraint Theory

Results in “What the Hell Effect”

BATTLE

Dieters cognitive or mental efforts to resist that drive

Dieters physiological drive to eat (e.g.,

hormones & peptides)

Culture of Valuing Thinness

• High body self-consciousness• Healthy body esteem• High weight preoccupation

• Increased overeating• Emotional eating• Binge eating

• Dieting practices• Weight loss strategies

Feelings of shame, guilt, anger, sadnessIncreased weight over time

Negative Spiral

The Impact of Living with Weight Management Issues in Today’s World

Puhl RM et al, J Sch Health (2011)Puhl RM et al, Psych Bull (2007

Low body satisfaction

High depressive symptoms

Isoloation/withdrawal

Poor-self-perception of physical appearance

Disordered eating

Poor academic outcomes

Poor peer relationships

Increase risk & unhealthy behaviours

School absences

Medical Versus Self Esteem Concerns

Most Kids:• Want to lose weight to make the teasing and

harassment stop• They would prefer to have diabetes and be thin than

to be “fat” and “healthy”

But by suggesting that children focus on weight as an outcome we are setting them up for weight

preoccupation, dieting and likely weight gain

A paradigm shift…

A growing trans-disciplinary movement called:

Health at Every Size

HAES challenges the value of promoting weight loss and argues for a shift in focus to weight-

neutral outcomes

Bacon & Aphramor (2011)

The HAES ApproachThe HAES approach is associated with statistically and clinically relevant improvements in:

Physiological measures (e.g. blood lipids)

Health behaviours (e.g. eating & activity habits)

Psychosocial outcomes (e.g. self esteem and body image)

Bacon L et al, 2011

Key Principles

Key Principles

Obesity Management is About Improving Health and Well-

being, and not Simply Reducing Numbers on the Scale

Weight bias can be a barrier to weight management

Key Principles

Interventions should include addressing ‘root causes’ of

obesity and removing roadblocks for families to

make healthy changes

Key Principles

A Child’s ‘Best’ BMI May Never Be His or Her ‘Ideal’ BMI

Key Principles

Success is different for every child and family
