  1. Study waves and their review identification (ID) numbers are described in Supplementary Table S2. IDs listed for study waves for which data was identifiable to the review team and clear. Data was given the designation ‘unclear’ and excluded from the list above if it was not recorded, could not be identified from research articles or other publicly available documentation, was not obtained through correspondence with the study team, or otherwise could not be identified with certainty by the review team. *For reporting of accelerometer wear instructions and minimum wear criteria IDs listed denote studies for which the required number of wear days, and hours of wear per day was identifiable. †For reporting of adverse events, IDs listed denote studies for which recorded information regarding the number and/or nature of adverse events
