Community Gardens Participation in Promoting Sustainable Lifestyles in Urban Settings: the JArDinS Study

Each participant was issued with a food supply diary to record details of their household food supply and related trips over 1-mo period. Household food supply included food purchases, food gift/donation, and potential crops from the garden. Away-from-home food consumption was not recorded. For each food purchase, participants provided details of date, place of purchase, foods purchased (name, quantity and expense incurred), and trip made (origin/where the trip started, destination/where the trip ended, and mode of transportation). When till receipts were available in grocery stores or supermarkets, participants were asked to collect them in an envelope placed at the end of the food supply diary. To facilitate data entry, all family members were encouraged to help filling out the diary.

Participants were instructed to wear a triaxial accelerometer (wGT3X-BT or wActiSleep-BT, Actigraph, Pensacola, FL, USA) fitted with an elastic strap on right side of the hip for 9 consecutive days, except for bathing and performing activities in the water. The Actigraph was accompanied by an activity logbook in which participants were required to daily record time when awake and sleeping, and, if any, time and duration of workout or device removal

Participants received by email a link to complete an online questionnaire about mental and social health, sensibility to food waste, and connection with nature
