Vascular and Metabolic Effects of Vitamin D Supplementation Associated With Lifestyle Management in Obese Adolescents

Patients randomized to this group will receive 4000 UI of Vitamin D3 per day for 90 days.

Patients randomized to this group will receive placebo for 90 days.

Lifestyle and dietary management at the Saint Pierre Institute (Palavas-les-Flots, France) occurs for three months. Nutritionally speaking, each child or adolescent receives a controlled and balanced diet, consistent with the recommendations appropriate for his/her age, slightly hypocaloric or normocaloric. This dietary approach is complemented by a nutrition education program and supervision by a doctor and a dietician. Three hours of exercise training per week are scheduled; these sessions include adapted aerobic activities supervised by instructors and educators at the center.

Patients in this group do not have experimental intervention in order to provide measures of a real-life control group.
