What is the purpose of this trial?

The trial aims to promote physical activity and reduce sedentary time in children and adolescents with health risks such as obesity, high blood pressure, or blood sugar issues. Wearable sensors gather data on movement and activity to help tailor a personalized plan. Participants join either a group using this sensor-based physical activity intervention or receive traditional physical activity counseling. Children aged 6 to 18 with a BMI above the 95th percentile (indicating obesity) may be suitable if they have no conditions preventing physical activity. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could improve health outcomes for children.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

What prior data suggests that this lifestyle intervention is safe for children and adolescents?

Research has shown that using wearable sensors to track physical activity in children is generally safe. In past studies, children who used these devices experienced positive outcomes. For instance, one study found that participants had a lower body mass index (BMI) and increased activity levels, suggesting that the devices were well-received.

Another study examined safety and found no major problems linked to wearable technology. These sensors collect data like heart rate and movement, which helps create personalized activity plans. The technology has been used in similar programs without major safety concerns.

Overall, using wearable sensors in these programs appears safe and is well-liked by participants, making it a promising way to encourage physical activity in children. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Lifestyle Promotion Intervention for Obesity because it leverages technology to create a personalized approach to increasing physical activity. The sensor-based intervention equips children with devices like heart rate monitors and GPS trackers to gather real-time data, which is then used to develop a tailored activity plan based on their everyday environment. This data-driven, customized approach offers a fresh perspective compared to traditional physical activity counseling, which does not utilize sensor data for personalization. By integrating technology to provide a spatio-behavioral diagnosis, this method holds the promise of more effectively promoting physical activity among children.

What evidence suggests that this trial's treatments could be effective for obesity?

Research shows that wearable sensors can help manage obesity and improve lifestyle habits. In this trial, one group of participants will receive the Sensor-based Physical Activity (PA) intervention, which uses these sensors to track activity and develop personalized lifestyle plans. Studies have found that such sensor-based interventions can lead to weight loss, a smaller waist size, and a noticeable drop in BMI (a measure of body fat based on height and weight), while also increasing daily activity levels. By personalizing lifestyle plans with these devices, participants can stay more committed and see better results. This evidence suggests that using sensors to monitor activity and provide tailored advice might help reduce obesity-related risks in children and teens. Meanwhile, another group in this trial will receive Traditional PA counseling, which does not rely on sensor data for intervention. ^{5 6 7 8 9}

Are You a Good Fit for This Trial?

The Dynamo trial is for children and teens aged 6 to 17 with obesity, specifically those with a BMI over the 95th percentile for their age and sex. It's not suitable for kids who have physical or mental health issues that would limit their ability to be active.

What Are the Treatments Tested in This Trial?

Interventions

• Sensor based PA intervention
• Traditional PA counseling

Trial Overview This study tests a lifestyle program aimed at increasing physical activity and reducing sitting time in young people with obesity-related health risks. Participants will either get standard advice on being active or use wearable sensors that help tailor this advice.

How Is the Trial Designed?

Group I: Traditional PA counseling Experimental Treatment 1 Intervention

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.

Group II: Sensor based PA intervention Experimental Treatment 1 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.

Sensor based PA intervention is already approved in Canada for the following indications:

Approved in Canada as Dyn@mo lifestyle intervention for:

• Cardiometabolic risk factors in children and adolescents
• Obesity
• Hypertension
• Disorders in glucose regulation
• Dyslipidemia
