NCT05992350

Brief Summary

The goal of this observational study is to test the Garmin Vivosmart in children and youth (8-21) with Type 1 Diabetes (T1D) and their parents. The main questions it aims to answer are:

  • Does the Garmin Vivosmart increase physical activity (PA)?
  • Does the Garmin Vivosmart improve T1D status Participants will:
  • Wear the Garmin Vivosmart (4 or higher) for a year
  • Complete surveys at the beginning, middle and end of participation asking about your T1D, T1D management, and PA
  • Parents of children will also complete similar surveys about T1D

Interventions

The Garmin physical activity tracker is worn like a watch on the user. The tracker assesses several physical states, indicates when the body is at optimal time for activity or when the body needs to rest. The tracker also monitors stress levels and prompts relaxation when appropriate. The tracker sets goals with participants based on previously completed activity. The tracker alerts participants after a period of inactivity, encourages regular movement throughout the day, and decreases the amount of time spent sedentary.
