A Pilot Study on the Impact of Accelerometer Data Reduction Algorithm Selection and the Potential Implications on Behavior Change Recommendations (OR08-03-19)

摘要

ObjectivesPhysical activity (PA) estimates obtained from recent accelerometer data reduction algorithms have not been compared in women of reproductive-age, a population more likely to engage in unstructured and intermittent PA (such as household cleaning, walking) than men. We investigated whether the accelerometer data from the Crouter, Sasaki and Santos-Lozano algorithms: 1) reported significantly different PA estimates; 2) interacted with weight and age to modify PA estimates; and 3) provided different prevalence of adults meeting PA guidelines.
