2. POINTS TO BE COVERED • Overview of Childhood Overweight/Obesity Epidemic • Medical Complications • Causes of Childhood Obesity • Call to Action-The Role of Healthcare Professionals • Nutritional Recommendation

3. Definition of Obesity • At risk for obesity is: • BMI-for-age & gender from 85th to 95th percentiles • Obesity is: • BMI-for-age & gender ≥ 95th percentile • 30% of U.S. children and adolescents are at risk or obese [NHANES, USDHHS 2004]

5. BODY MASS INDEX • BMI is the most effective tool for the assessment of overweight and obesity in children • BMI provides a guideline for weight in relation to height BMIFormula weight (kg) / [height (m)]2 or Weight in pounds x 703/height in inches2 Must plot on CDC growth chart!

12. Exception to BMI Metric:Use Waist Circumference • If BMI > 85th % and child does not appear obese-waist circumference at the umbilicus can be obtained. • Age 6-12 years: Waist circumference >61 cm or 24 inches (probably overweight) • If pubertal: Waist circumference > 95 cm or 37.5 inches (probably overweight) [Pediatrics 2005; 115 1623-1630]

16. Medical Complications

17. Common Medical Consequences of Overweight • Hyperlipidemia - Elevated levels of cholesterol • Glucose Intolerance - Type 2 Diabetes • NAFLD - Nonalcoholic fatty liver disorder • NASH - Nonalcoholic steatohepatitis (fatty liver disease) • Cholelithiasis - Gallstone • Hypertension - High blood pressure

18. Psychological Complications of Childhood Obesity • Lower self esteem • Depression • Loneliness • Teased by peers • Bullying • Absenteeism • High-risk behaviors • Oppositional-defiant disorder

19. Socioeconomic Consequences of Obesity • Fewer years of advanced education • Lower family income • Higher poverty rates • Lower wages • Lower marriage rates • Less likely to be hired

20. Contributing Factors to Obesity • Genetics • Behavior • Exercise • Diet • Environment

21. Genetics

22. Genetics • Heredity may influence fatness and regional fat distribution • Rare genetic syndromes may co-exist with obesity • Heredity may co-exist with environmental factors • Parental modeling of both eating and • exercising behaviors • Both parents obese

23. Behaviors • Low-energy Expenditure • Watching TV or playing video games • High-calorie snacks when watching TV • Diet • Regular consumption of high calorie foods, vending machine snacks, soft drinks • Psychological Factors • Overeating to cope with problems or to deal with emotions • Family/Social Factors • Parents purchasing unhealthy foods

24. Environment • Built Environment • Sidewalks • Parks • Food Deserts • School Bus • Safety

25. What Can We Do? • Carefully avoid a blaming approach • Understand and acknowledge role of genetics • Some individuals gain weight more easily • Better to use words like “unhealthy weight” or “weight problem”

26. Focus on health and function rather than appearance • Growing into a healthy body weight instead of an ideal weight • Choosing a target weight is often unrealistic and leads to discouragement

27. Behavioral Change Model • Self monitoring of target behaviors • Log of food • Log of activity • Stimulus Control • Reducing access to unhealthy behavior such as juices and sodas or removing a television from bedroom • Making fruits and vegetables more accessible

28. Behavioral Change Model • Goal setting • SMART • Specific • Measurable • Attainable • Realistic • Timely • Contracting • Positive Reinforcement • Negotiated by parent and child • Rewards should be small activities or privileges; food should not be used as reward

29. Family Centered Communication • Behavior change should be collaborative rather than prescriptive • Child should be directly involved in decision making

30. Motivational Interviewing • Encourage patients to identify reason for behavior change, including their solutions • Tone should be nonjudgmental, empathetic and encouraging. • Goals should be achievable • Select a few specific behaviors related to weight management • Avoid Scare Tactics

31. Activity Assessment • Home • TV in bedroom, access to free play, organized sports • School • Physical education, affordability of activities, safety concerns • Lifestyle Activity

32. Activity • Emphasize activity, not exercise - 60 minutes daily • Vary the activity • Find activity child likes • Encourage organized sports or structured sports • Encourage activities done as a family

33. Nutritional Assessment • Frequency of eating out • Intake of calorie-containing beverages • Frequency and portion size of energy dense foods (cookies, chips, ice cream) • Servings of vegetables and fruits • Number of meals and skipped meals • Typical snacking patterns • School lunch-purchased or brought from home

34. Dietary Strategies for Families • Balance calories with activity to maintain growth • 60 minutes of play or physical activity daily • Fruits and veggies daily • Limit juice and sugar sweetened beverages • Change to skim milk • Eat whole grain breads and cereals

35. Dietary Strategies for Families • Reduce salt intake, including processed foods • Eat lean meats • Eat more fish • Substitute tofu and beans for meat • Use vegetable oil or soft margarines in cooking • Limit high calorie sauces, e.g. Alfredo
