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.

Conditions

Obese

Keywords

obesity; physical activity; metabolism; environment; obese children, as defined by a body mass index > 95th percentile; for age and sex

Outcome Measures

Primary Outcomes (1)

• Change in physical activity levels

  Physical activity will be measured using accelerometry and we will use time spent in moderate to vigorous physical activity as our primary measure of PA

  Baseline and 1 year

Secondary Outcomes (4)

• Change in blood pressure

  Baseline and 1 year

• Change in glucose homeostasis

  Baseline and 1 year

• Change in lipid status

  Baseline and 1 year

• Change in body mass index

  Baseline and 1 year

Study Arms (2)

Sensor based PA intervention

EXPERIMENTAL

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.

Behavioral: Sensor based PA intervention

Traditional PA counseling

OTHER

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.

Behavioral: Traditional PA counseling

Interventions

Sensor based PA intervention BEHAVIORAL

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.

Sensor based PA intervention

Traditional PA counseling BEHAVIORAL

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