Characteristics of estimated activity monitor wear adherence for a large-study of free-living adults (N = 523). Hours of Activity Monitor Wear = estimate of how many hours of a day an activity monitor was worn. Panel A demonstrates the time of day where activity monitor removals occurred for all of the daily records. Panel B is a histogram demonstrating the hours of activity monitor wear (per day) for all of the daily records. Panel C is a histogram demonstrating the number of days of data (assuming a "day" is more than 12.4 hrs/day) for all of the daily records.
