Associations Between Physical Activity and Sedentary Behavior Profiles and Carotid Intima-media Thickness in Adolescents With Obesity (CARADO)
Physical activity behaviors are key and modifiable factors of cardiovascular health from childhood. They encompass both physical activity, defined as any bodily movement produced by skeletal muscles that results in energy expenditure, and sedentary behavior, characterized by low energy expenditure while awake. Studying these behaviors in their diversity, beyond a simple active-inactive opposition, allows for a better understanding of their effects on health.
In adolescents, high levels of sedentary behavior and low levels of physical activity are both associated with an increased risk of overweight or obesity. Current recommendations advocate for at least 60 minutes of moderate-to-vigorous physical activity per day and the reduction of sedentary time. However, more than 80% of French adolescents do not meet these recommendations, a trend that is even more pronounced and problematic among those living with obesity.
Pediatric obesity is associated with early alterations in vascular health. Carotid intima-media thickness (cIMT), measured by ultrasound, is a recognized biomarker of future cardiovascular risk. Several studies have shown that sustained physical activity is associated with lower cIMT and better endothelial function, independently of body size. However, the methodological limitations of current studies, and the lack of data specific to adolescents with obesity, highlight the need for further research.
This project aims to better understand, in adolescents with obesity, the associations between physical activity and sedentary behavior profiles and physical fitness, on the one hand, and structural parameters, particularly cIMT, and vascular functional parameters known for their value as subclinical biomarkers of cardiovascular risk, on the other hand.

Anthropometry
Tidsramme: At the inclusion (single assessment visit )
|
Height (cm), body mass (kg) used to calcultate the body mass index (BMI in kg/m² and z-score) as body mass/height*height.
Body composition is assessed using bioelectrical impedance analysis (BIA) mBCA SECA.
Fat mass, fat-free and muscle mass are measured in kg, reported to the body mass in %.

Tanner Stage
Tidsramme: At the inclusion (single assessment visit)
|
A clinical assessment performed by a medical doctor to determine the stage of pubertal development based on the development of secondary sexual characteristics.
Pubertal development is classified into five stages, ranging from stage I (prepubertal) to stage V (full maturation).
