Cut points matter: differences in estimates of physical activity engagement using accelerometer data
Purpose: Accelerometers are used to assess physical activity intensity levels and durations across populations. This is done by dividing the device output into categories that correspond to light, moderate, and vigorous physical activity. Cut points provide where these dividing lines should be. However, there is not a consistent set of cut points for any given population. This makes inter-study comparison difficult and it is unknown how using different cut point sets affects outcomes. The aim of this study is to determine agreement between four different commonly used cut points. Procedure/Description: ...
