Slide 1: 

Can the Metabolic Syndrome identify children with insulin-resistance?

Slide 2: 

Haffner SM Diabetes. 41: 715–722. 1992 Obesity plays a central role in the Metabolic Syndrome, which also includes insulin resistance, hypertension and hyperlipidemia. Early identification of the Metabolic Syndrome is important in order to identify those most at risk for T2DM Background

Slide 3: 

Objective: To determine the association between children's Metabolic Syndrome and Insulin-resistance

Slide 4: 

167 school children were examined. Mean age = 6.7 +/-3 y April-August 2004 BMI, waist, BP, Tanner, glucose, Insulin, Lipids, CRP, adiponectin 73 were Obese, 41 overweight Methods

Slide 5: 

Inclusion criteria Normal physical examinations Normal renal and thyroid function Exclusion criteria Use of medication that alters BP or glucose or lipid metabolism

Slide 6: 

Criteria for Pediatric Metabolic Syndrome. *based on our measurements of 5130 normal children (unpublished data)

Prevalence of risk factors for the MS

Slide 10: 

Results 129 (77%), 20 (12%), 10 (6%), and 8 (5%) were Tanner stage I, II, III, and IV respectively HOMA-IR for patients with one through four components for metabolic syndrome was higher (Beta = 0.6; 95%CI: 0.4-0.7; P<0.0001) The prevalence of metabolic syndrome rises with increasing Tanner stage as insulin-resistance increases in puberty ( p=0.019).

Slide 12: 

Conclusion Insulin-resistance was associated with pediatric metabolic syndrome. This suggests that early identification of metabolic syndrome could predict future CVD and T2DM
