Abstract

We validated the performance of Fitbit sleep tracking devices against research-grade actigraphy across four days/nights on 38 young adult good and poor sleepers. Fitbit devices underestimated changes in nightly sleep compared to standard actigraphy. Nevertheless, we estimated the Fitbit captures 88% (poor sleepers) to 98% (good sleepers) of actigraphy estimated sleep time changes, which may still be useful for qualitative sleep analysis over time. Key Words: Sleep tracking, Fitbit, validation, actigraphy
