Status Information


Term Description

An accelerometer-based pedometer is used to measure the number of steps over a desirable measurement period (for a robust assessment of free-living walking, a minimum of 3 days is recommended). The participant is asked to wear the pedometer during all waking hours of the study period. Data (number of steps per hour or per day) is downloaded from the pedometer after being retrieved from the participant. The hip placements of the pedometer (on a belt or in the front pants pocket) have been shown to yield the best walking assessments. The absolute accuracy (number of steps and or distance) may vary with different pedometers, data/signal filters used by the devices, and/or placement locations. Follow manufacturers' operation manuals for specific calibration procedures if needed. It is generally not recommended to use pedometer-predicted energy expenditure values.
