About This Presentation

Description : Check out this medical PowerPoint presentation titled "Pediatric Obesity and the Metabolic Syndrome" by Whitney Brown, MD.

This medical PowerPoint presentation talks about pediatric obesity, a growing concern worldwide which is associated with a number of health problems, including the metabolic syndrome. The metabolic syndrome is a collection of risk factors that increase the risk of developing cardiovascular disease, type 2 diabetes, and other health problems. These risk factors include Central obesity (excess fat around the waist), High blood pressure, High blood sugar, High triglycerides (a type of fat in the blood), and Low HDL cholesterol (the "good" cholesterol), etc.

Children who are overweight or obese are more likely to develop these risk factors, which can lead to the development of the metabolic syndrome. The exact causes of the metabolic syndrome are not fully understood, but it is believed to be related to a combination of genetic and environmental factors.

Prevention and treatment of pediatric obesity and the metabolic syndrome involves lifestyle changes such as increasing physical activity, reducing sedentary behavior, and improving the quality of the diet. In some cases, medications may be prescribed to help manage specific risk factors. It is important for parents and caregivers to work with healthcare professionals to monitor childrens weight and health status and to address any concerns or risk factors as early as possible.

Pediatric Metabolic Syndrome: Need for a Standard Definition Reviewed 27 articles 46 unique definitions of pediatric metabolic syndrome Most emulated the NCEP approach BMI or waist circumference Blood pressure Lipid levels Glucose abnormalities Different cut-offs/percentiles were used in the various definitions Ford ES, et al.

Obesity: Prevention Breastfeeding alone until age 6 months, and encourage BF even after intro of solid foods Do not skip meals Eat meals as a family; Dining out ≤ 2x/week Avoid high sugar beverages ≤ 12 oz of 100% fruit juice daily Drink 3-4 8-oz glasses of skim milk daily Ca and Vit D fortified Portion sizes should be limited to the amount of recommended calories for age Keep TVs and other electronics out of bedrooms ≤ 2 hours of screen time daily 1 hr of moderate intensity aerobic exercise daily American Heart Association 2008 Policy Statement
Slide 25-

Obesity: Treatment Stages Prevention (P) All children Promotion and support for: Breastfeeding Family meals Limited screen time Regular physical activity Yearly BMI monitoring Prevention Plus (PP) BMI between the 85th - 94th percentiles 5 servings of fruits and vegetables/day 2 hours or less of screen time 1 hour or more of physical activity 0 sugared drinks Structured Weight Management (SWM) If PP fails BMI is between 95th - 98th percentiles More frequent follow-up with written diet and exercise plans Comprehensive Multidisciplinary Intervention (CMI) When 3 - 6 months of SWM fails More frequent visits with an MD and a dietician May include exercise and behavioral specialists Tertiary Care Intervention BMI ≥ 99th percentile with associated comorbidities SWM and CMI failed Incudes everything else plus: Meal replacements Pharmacotherapy Bariatric surgery Barlow SE and the AAP Expert Committee.

Obesity: Pharmacotherapy Orlistat (Xenical or Alli) FDA-approved for children ≥ 12yo Inhibits GI lipases Dose: 120 mg TID During or up to 1hr after meal MVI 2 hrs before or after orlistat GI side effects common Metformin Not FDA approved for obesity For T2DM Approved in children ≥ 10yo Metformin ER FDA approved ≥ 17yo Major effects: ↓ hepatic gluconeogenesis ↑ peripheral insulin sensitivity
Slide 29-

Metformin (cont.) Starting dose 500 mg Qday, increased to a max of 1000mg BID Titrating slow can limit GI-side effects MVI with vit B12 Contraindictaed in: Renal failure Chronic hypoxic states Use of radiocontrast dye Very rare side effects: decreased platelet aggregation and hemolytic anemia Check BUN/Cr and CBC Before initiation Every 2 years

Final Thoughts Childhood obesity has reached epidemic proportions There is no current accepted definition for pediatric metabolic syndrome Mainstay of treatment is DIET/EXERCISE counseling The counseling should start in early childhood and BEGINS with the caregivers Pediatrician or Family practitioner Consider referral to weight management program After age ≥ 6 years if Prevention and prevention plus fail BMI ≥ 95th percentile with co-morbidity BMI ≥ 99th percentile
