Study Population



Inclusion Criteria:

  • Children will be enrolled into lean, overweight or obese groups based on Body mass index (BMI) calculated according to standard methods. International standards for sex-and age-specific BMI centiles for subjects aged 2-18 years will be used. The 95th centile of BMI reference is the cut off point for childhood obesity. Overweight and obese children are defined as those with a BMI higher than the centile curves.

Exclusion Criteria:

  • presence of renal, liver and/or cardiovascular diseases;
  • hypertension;
  • metabolic and/or endocrine disorders;
  • genetic syndromes;
  • histories of chronic allergies, acute infectious or inflammatory diseases during the last 3 months preceding the study
