Impact of accelerometer data processing decisions on the sample size, wear time and physical activity level of a large cohort study

Background Accelerometers objectively assess physical activity (PA) and are currently used in several large-scale epidemiological studies, but there is no consensus for processing the data. This study compared the impact of wear-time assessment methods and using either vertical (V)-axis or vector ma...
