Brief Summary

The high prevalence of childhood obesity is a major public health issue, worldwide. Childhood obesity is associated with a high risk of cardiovascular events in adulthood, but recent studies also point out the development of cardiovascular complications in childhood or adolescence justifying the need for early detection and appropriate therapeutic management to prevent the development of more severe abnormalities. This project proposes to evaluate the myocardial function in a fine and comprehensive way (longitudinal, circumferential and radial linear deformations, and rotation / torsion mechanics) from the deformation imaging (MRI and high-resolution echocardiography), in obese adolescents following a lifestyle intervention combining diet and physical activity.

Study Arms (2)

Obese adolescents

EXPERIMENTAL

BMI greater than the 97th percentile of national curves. Participants will follow a 3-month lifestyle intervention

Behavioral: 3-month lifestyle intervention

Control group

NO INTERVENTION

to be normal-weighted (no obesity if overweight, \<85th percentile of national curves).

Interventions

Adolescents from the intervention group will be enrolled at the obesity center for the whole school year (i.e., 10 months). The physical activity program consists of two training sessions (aerobic and resistance training) per week. There will be two measurement time: one at baseline (Day 0) and one at three months after the beginning of the lifestyle intervention (M3). The controls will be evaluated at baseline only.

Obese adolescents
