Validity of the Fitbit activity tracker in older adults

VALIDITY OF THE FITBIT ACTIVITY TRACKER FOR MEASURING STEPS IN COMMUNITY-DWELLING OLDER ADULTS

Presenter: Paul S

This module addresses: 

Question: What is the criterion validity of Fitbit step counts compared

to visual count and ActiGraph accelerometer step counts? What is the

accuracy of ActiGraph step counts compared to visual count, in communitydwelling

older people.

Conclusion: The Fitbit accurately tracked steps during the 2MWT but the

ActiGraph appeared to underestimate steps. There was strong agreement

between Fitbit and ActiGraph counted steps.

Key Practice Points:

• The Fitbit tracker is sufficiently accurate to be used among communitydwelling

older adults to monitor and give feedback on step counts.
