The CIRCUIT program (Centre pédiatrique d'interventions en prévention et en réadaptation cardiovasculaire) of the CHU Sainte-Justine is a multidisciplinary, personalized intervention for children with cardiovascular risk. This program includes an evaluation of the physical activity pattern using wearable sensors (accelerometer, heart rate monitor and GPS), to replace the physical activity practice of the patients in their respective real life context. The accelerometer will measure physical activity and heart rate, while the GPS will serve to obtain precise information about places visited and travels in the neighborhood. The data obtained with these tools will serve to develop indicators of the "environmental diagnosis". This information will help to personalize the intervention for each patient.

Inclusion Criteria:

- Children at risk of cardiovascular disease, including children with diabetes mellitus, overweight/obesity, hypertension, dyslipidemia

Exclusion Criteria:

- Patients with physical or psychological problems that impair their ability to participate in physical activity
