ActiGraph accelerometer-measured steps and MVPA
Daily steps and MVPA minutes were measured using the ActiGraph at baseline, 12 weeks, and 52 weeks. Participants were instructed to wear the device during all waking hours (except when showering or swimming) for 7 consecutive days on their non-dominant hip using a provided waistband and pouch. Data were sampled at a frequency of 90 Hz. Using ActiLife 6 software (version 6.13.3), raw accelerometer data were processed into 60-s epochs and subsequently scored using the Troiano 2008 adult cut points for classifying MVPA [
