Journal for the Measurement of Physical Behaviour @jmpbjournal.bsky.social · 27/04/2026

As consumer-grade #WearableMonitors are increasingly used in #PhysicalActivity #research, ensuring valid wear time is critical for producing accurate and unbiased estimates. However, some devices do not provide direct indicators of wear time, specifically when heart rate data are unavailable.

There are differences in participation, willingness, and ownership varying by age, education, health, migration background, and PA level. Some groups at higher risk for adverse health outcomes were less likely to participate in monitor measurements, raising concerns for biased population estimates.
