Prevalence of obesity (body mass index >95th percentile) among children and adolescents 2 to 19 years of age in the United States between 1971 to 1974 and 2009 to 2010 shows a recent
plateau from 2003 to 2004 on.

Weight status cannot be determined without assessing BMI
1966

http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/english_bmi_calculator/bmi_calculator.html
CDC BMI Calculator:
“Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.” CDC
BODY MASS INDEX (BMI): What is it and how does it work?
•! Quetelet Index initially created by Adolphe Quetelet (1796-1874) •! Dr. Ancel Keys (the Mediterranean Diet) proposed use of BMI in 1970’s •! 1985 NIH Consensus Development Panel promoted use in practice Dr. Ancel Keys
Caveats about BMI •! Assumes proportion of
muscle, fat, bone, fluid so does not actually measure obesity = excess fat
•! Cannot be used in children less than 2 years old
•! Height and weight measurements must be accurate
BMI video located on the Lean Team website: http://academicdepartments.musc.edu/lean_team/physicians/bmicheck.html
Definition of Overweight and Obesity in Children and Adolescents
•! % Based on BMI distribution in 1970’s •! Risk categories based on adult morbidity •! Overweight = BMI > 85% - 94% •! Obese = BMI > 95% or •! Obese = BMI > 30
Pediatrics 2007 120, (suppl 4)
14
Body proportion changes during childhood and adolescence
1. Normal BMI for children varies by age and gender
2. BMI normative data not available for children < 2 years old
3. Adiposity rebound is important
4. BMI > 30.0 is obesity regardless of percentile
Adiposity rebound = age at which BMI first increases Adiposity rebound <5 associated with >3 BMI units increase by age 18-21

Educational Objectives
•!Review recent clinical practice recommendations for diagnosis, treatment and prevention of overweight and obesity in children and adolescents •!Develop a plan for use of the new
SCMA toolkit in clinical practice
Obesity Prevention / Treatment in Well Child Care
•! Assessment of BMI at least annually •! Promotion of healthy life style •! 5-2-1-0 Plan •! Stage I – IV Treatment Plan
Staying Healthy: Weight Fruit Vegetables Whole grain Calcium Physical activity
16
5-2-1-None •! > 5 fruits/vegetables •! < 2 hours of screen time •! > 1 hour of physical
activity •! No sugar sweetened drinks
http://www.choosemyplate.gov/
Additional Screening for an Obese Child •! Insulin Resistance – random/fasting insulin •! Diabetes – random / fasting BS, hgb a1c •! Hyperlipidemia – random / fasting cholesterol /
lipid panel •! Hypertension - accurate blood pressure •! Obstructive sleep apnea - sleep study •! NAFLD – Liver function tests •! Hypothyroidism - only if short, sudden onset, or
additional symptoms
Expert Committee Recommendations of the Assessment, Prevention and Treatment of Childhood and Adolescent Obesity 2007
STAGE 1: 5-2-1-0 and lifestyle counseling (breakfast, limit eating out, family meals 5-6/week). Allow child to self regulate. Monthly FU. Goal of weight maintenance with growth.
STAGE 2: Diet plan limiting energy dense foods, structured meals and snacks, supervised active play 1 h/d and screen time < 1 h/d. Goal of weight maintenance to decrease BMI or lose < 1 lb/m.
STAGE 3: Multidisciplinary team with structured behavioral modification program about food and activity. Goal weight loss 1 lb/month age 2-5y or up to 2 lb/week > 5 years
STAGE 4: Referral to pediatric tertiary weight management center (MUSC Heart Health)

> Of the following: •! Elevated fasting triglycerides •! Low HDL cholesterol •! Elevated fasting glucose •! Increased waist circumference •! Elevated systolic BP
Among 1960 children > 12 years old in NHANES: 2/3 had one finding of metabolic syndrome 1/10 had metabolic syndrome (1/3 of those with BMI > 85%) (Circulation 2004;110:2494-2497)
* No standard definition of pediatric metabolic syndrome

Motivational Interviewing •! Defined in 1983 by Miller
& Rollnick in treatment of adults with substance abuse
•! Patient-centered, only the patient can make a change
•! Starts with patient’s Stage of Change (Prochaska and DiClemente), moving from Pre-contemplation to action and maintenance www.motivationalinterview.org
21
1.! Express empathy Acceptance facilitates change Skillful reflective listening in fundamental Ambivalence is normal
2.! Develop discrepancy The patient should present the argument for change Change motivated by a perceived discrepancy between current behavior and goals
3.! Roll with resistance Avoid arguing!!!! Do not directly oppose resistance New perspectives invited but not imposed Patient is the primary source of answers and solutions
4.! Support self-efficacy Patient’s belief in possibility of change is important Patient, not the doctor, is responsible for carrying out change Doctor’s belief in patient’s ability to change becomes self fulfilling
Underlying Principles of Motivational Interviewing
Primary Techniques of Motivational Interviewing
•! Open-ended questions vs close-ended •! Reflective listening •! Affirmations •! Summary statements •! Evocation of change talk vs importance and
ability rulers
Using the Toolkit Questionnaire: !! Have patients/parents fill
it out during triage/while waiting
!! Use for all patients not only those who are overweight/obese
!! Review during interview !! Base MI on “change
talk” selected by patient !! Focus on only one thing
at a time !! Use handout for that one
item !! FU in 1 month !! Celebrate success
22
Example: “Based on your answers, is there ONE thing you would like to help your child change now” Eat more fruits and vegetables (Preparation stage of change) MI: Good choice! You can do it! Fruits & vegetables are … Have you tried: The 3 bite rule Low fat salad dressing dip Fruit smoothie Don’t give up; it takes 7-10 times to get a kid to like a new food
Example: Nothing checked MI: What do you think about this new questionnaire? Have you ever thought about making any of these changes to keep your child healthy? I know you are concerned about the diabetes that runs in your family. Getting a healthy dinner together every night can be really hard; I have trouble with it myself!

Although they have the same chemical composition, fructose has a more open structure than glucose and therefore causes more gycoslylation of proteins than does glucose. Gylcation (non-enzymic glycosylation) inactivates glutathione reudctase Blakytny & Harding, Biochem J 1992 288 303-307
Glycation = Non-enzymatic binding of sugars to protein
