Minute-level NHANES step counts released on PhysioNet

Lily Koffman and John Muschelli released minute-level step counts and physical activity data for NHANES 2011–2014 on PhysioNet (doi:10.13026/d7sw-f662). The dataset applies five step counting algorithms and the ActiGraph Activity Count algorithm to the raw 80 Hz wrist accelerometry, and includes minute-level step counts, Activity Counts, MIMS, wear predictions, and wear flags for all participants who wore accelerometers. See our step counting research for the papers behind it.
