Study Details

Brief summary:

The Dyn@mo lifestyle intervention (CHU Sainte-Justine, Quebec, Canada) targets children and adolescents aged 6 to 17 years old with cardiometabolic risk factors, such as obesity, hypertension, disorders in glucose regulation or dyslipidemia. Its primary goal is to promote physical activity and reduce sedentary time to improve childrens' cardiometabolic profile. To do so, the intervention relies on gathering data on mobility and physical activity using wearable sensors. These data provide a detailed picture of real-life conditions and physical activity levels, improving the health care professional's ability to tailor counseling. The investigators are presently in the implementation phase of this intervention.

Interventions and Outcome Measures

Arms

experimental: Sensor based PA intervention

Children will be equipped with a heart rate monitor, a GPS receiver and an accelerometer for collection of heart rate, mobility and physical activity free-living data during a 7-day period. This will provide a 'spatio-behavioural diagnosis' using a map-based interactive web application. This data will be used to developed a tailored plan to promote physical activity in the child's every day environment.

other: Traditional PA counseling

In this arm, while children will wear the same sensors as in the intervention arm, the intervention will not rely on data gathered using the wearable sensors. Rather, a traditional physical activity counseling strategy will be adopted in this control group.

Traditional PA counseling

Children will be encouraged to enhance their physical activity levels using traditional behavioral approaches.

  • Change in physical activity levels [ Time Frame: Baseline and 1 year ]
