The investigators first randomized vending locations (e.g., floors) with beverage machines so that all machines on the same floor displayed the same label. They then randomized the remaining "solo" snack locations. Monthly sales data provided by the City's vending contractor indicated consumer choices. Research assistants also asked a subset of consumers (N=1,065) about their purchases. Intercepts were not allowed in the courts/offices location type and were not conducted at correctional facilities with low traffic. The aim was to collect 10 intercepts per machine visited, distributed over the entire study period, however the study was cut short in March 2020 by the Covid pandemic., primaryPurpose: PREVENTION, maskingInfo masking: NONE, enrollmentInfo count: 1065, type: ACTUAL, armsInterventionsModule interventions name: exposure to healthy labels only, interventions name: exposure to healthiness information, interventions name: exposure to physical activity equivalents, interventions name: exposure to sweetened beverage tax messaging, outcomesModule primaryOutcomes measure: Percentage of beverages sold with calories per month, primaryOutcomes measure: Calories sold from beverages per month, if beverages with calories sold, primaryOutcomes measure: Calories sold from snacks per month, primaryOutcomes measure: Likelihood of selecting a healthy beverage, primaryOutcomes measure: Likelihood of selecting a moderately healthy beverage, primaryOutcomes measure: Likelihood of selecting a less healthy beverage, primaryOutcomes measure: Likelihood of selecting a healthy snack, primaryOutcomes measure: Likelihood of selecting a moderately healthy snack, primaryOutcomes measure: Likelihood of selecting a less healthy snack, primaryOutcomes measure: Total beverage units sold per month per machine., primaryOutcomes measure: Total snack units sold per month per machine, secondaryOutcomes measure: Total revenue per month per beverage machine, secondaryOutcomes measure: Total revenue per month per snack machine, secondaryOutcomes measure: Total calories sold per customer trip, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: University of Pennsylvania, city: Philadelphia, state: Pennsylvania, zip: 19104, country: United States, geoPoint lat: 39.95233, lon: -75.16379, hasResults: False
