Low Grade Inflammation in Childhood Obesity : an Independent Risk Factor for Endothelial Dysfunction

"* Actual Height and weight~* Calculated BMI from measured weight and height.~* Pubertal development (Tanner stage)~* Waist circumference~* Skin fold measurement (Triceps and Subscapular)~* Waist-to-height ratio will be calculated from measured height and waist circumference."

Blood pressure will be measured using an oscillometric, electronic device (Mindray). The blood pressure will be measured 3 times; the first measurement will not be taken into account and the mean of the second and third measurement will be considered as the real blood pressure.

The investigator will measure the pulse wave amplitude by using a finger plethysmograph (peripheral arterial tonometry). The investigator will use the EndoPAT device from Itamar Medical Ltd. At the end of the examination, the participants will be asked to give a VAS-score (Visual Analogue Pain scale).
