Background |
The World Health Organization recognizes universities as an important health-promotion setting, including in healthy food provision. Previous research shows that healthy food retail interventions also need to consider commercial sustainability, including financial outcomes, and should take a holistic approach to consumer experience.
Objective |
Our aim was to determine the health behavior and commercial outcomes of a multicomponent traffic light–based healthy vending policy implemented as one part of a holistic university food policy. The hypothesis was that purchases of less healthy “red” beverages would decrease compared with predicted sales, that purchases of healthier “green” and “amber” alternatives would increase, and that there would be no change in revenue.
Design |
A quasi-experimental design evaluated a real-world food policy using monthly aggregated sales data to compare pre-intervention (January 2016 to March 2018) and post-intervention period sales (December 2018 to December 2019).
Participants/setting |
Electronic sales data were collected from 51 beverage vending machines across 4 university campuses in Victoria, Australia.
Intervention |
A multicomponent policy was implemented between April and November 2018. Beverages were classified using a voluntary state government traffic light framework. Policy included display ≤20% red beverages and ≥50% green beverages; machine traffic light labeling; health-promoting machine branding; review of machine placement; and recycled bottle packaging.
Main outcome measures |
Changes in red, amber, and green volume sales, and revenue compared with predicated sales.
Statistical analyses performed |
Interrupted time series analysis of sales data compared post-policy sales with predicted sales.
Results |
In the 13th month post-policy implementation, there was a 93.2% (95% CI +35.9% to +150.5%) increase in total beverage volume sold and an 88.6% (95% CI +39.2% to +138.1%) increase in revenue. There was no change in red beverage volume sold, but increases in green (+120.8%; 95% CI +59.0% to +182.6%) and amber (+223.2%; 95% CI +122.4% to +323.9%) volume sold.
Conclusions |
Sustained behavior change and commercial outcomes suggest that holistic vending interventions can effectively promote healthier beverage sales.
