How Urban Interventions in Lower Socioeconomic Areas Influence Health Behaviors (UrbASanté Study)

Each participant completes a questionnaire (online or paper version) about socio-demographic characteristics, health outcomes (general health, respiratory health, and weight status), physical activity and sedentary behaviors, perception of neighborhood characteristics, air quality, and noise exposure.

Sample of 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. For each food purchase, participants provided details of date, place of purchase and foods purchased (name, quantity and expense incurred). 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.

Sample of participants was interviewed about their food provisioning practice and living conditions.

Sample of participant were instructed to wear air and noise sensors to record their daily environmental exposure for 7 consecutive days, except for sleeping, bathing and performing activities in the water. Particulate matter concentrations, the temperature, and the relative humidity were measured - the nitrogen dioxide (NO2) and ozone (O3) concentrations were determined with data loggers that integrate reliable electrochemical gas sensors. Noise levels was measured using noise dosimeters. Sensors were 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
