  1. aAccelerometer information in RECORD or predicted time in EGT
  2. bInformation from the mobility survey in RECORD and in EGT
  3. cRECORD and EGT questionnaires
  4. dShortest street network distance determined with ArcGIS from the residence or from the departure/arrival of each trip geocoded at the address level in RECORD or at the center of a 100 m square in EGT
  5. eThe area around the residence or departure or arrival point of each trip was defined with ArcGIS as a 1 km buffer following the street network, and information was aggregated at the level of this buffer; MVPA: moderate to vigorous physical activity
