McMaster Monitoring My Mobility (MacM3) study is the largest cohort study of its kind, tracking the everyday mobility and health trajectories of older Canadians. Our study aims to recruit 1,500 adults, aged 65 and older, and monitor their mobility for at least two years using an activity monitoring device called the TicWatch Pro 3 Ultra GPS.
Participants are invited to wear the TicWatch on their wrist for a 10-day period at baseline and then at four-month intervals throughout the year. Learn about the watch and what it measures with these videos. Additionally, participants have the option to wear a second activity monitoring device on their thigh (either an Actigraph or Axivity), alongside the wrist-worn device, following the same time and frequency pattern.
The study will measure key outcomes, such as life-space mobility, trip frequency, duration and mode, using the TicWatch GPS receiver. It will also assess sedentary behavior, including body posture and step counts, using the ActiGraph or Axivity. This novel and interdisciplinary study aims to provide valuable insights into late-life mobility decline in Canada. Furthermore, it will lay the foundation for developing tools and strategies to help older adults and their caregivers self-manage their mobility as part of their overall health.
