Dynamo: a Tailored Lifestyle Promotion Intervention Among Pediatric Patients With Cardiometabolic Risk Factors

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.

Exclusion criteria

  • children with a physical or psychological condition that would impair their ability to participate in physical activity

Treatment and study plan

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.

Traditional PA counseling

Behavioral

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

Primary outcomes

  1. Change in physical activity levels

    Time frame: Baseline and 1 year

    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

Secondary outcomes

  1. Change in blood pressure

    Time frame: Baseline and 1 year

    Both systolic and diastolic blood pressure will be measured

  2. Change in glucose homeostasis

    Time frame: Baseline and 1 year

    Both fasting blood glucose, and glucose 2hr post load (oral glucose tolerance test) will be measured

  3. Change in lipid status

    Time frame: Baseline and 1 year

    LDL, HDL, triglycerides and total cholesterol will be measured at baseline and after 1 year of follow-up

  4. Change in body mass index

    Time frame: Baseline and 1 year

    We will measure height and weight at baseline and at 1 year of follow-up and calculate differences in body mass index over the 1 year period
