Live Video Diet and Exercise Intervention in Overweight and Obese Youth: Adherence and Cardiovascular Health.

Objective: To evaluate adherence of overweight and obese adolescents to a live video lifestyle intervention. The impact on vascular and functional health was also assessed.

Study Design: Twenty adolescents 14.

Arterial applanation tonometry: feasibility and reproducibility in children and adolescents.

Background: Aortic pulse wave velocity (PWV) and augmentation index (AIx) are markers of vascular health and have recently been used in pediatric clinical trials. However, there are limited data on standardization of these measurements in pediatrics. The objective of this study was to prospectively test the feasibility and reproducibility of PWV and AIx in children and adolescents.
