Context:
Healthy vending machine policies are viewed as a promising strategy for combating the growing obesity epidemic in the United States. Few studies have evaluated the short- and intermediate-term outcomes of healthy vending policies, especially for interventions that require 100% healthy products to be stocked.
Objective:
To evaluate the potential impact of a 100% healthy vending machine nutrition policy.
Design:
The vendor's quarterly revenue, product sales records, and nutritional information data from 359 unique vending machines were used to conduct a baseline and follow-up policy analysis.
Setting:
County of Los Angeles facilities, 2013-2015.
Participants:
Vending machines in facilities located across Los Angeles County.
Intervention:
A healthy vending machine policy executed in 2013 that required 100% of all products sold in contracted machines meet specified nutrition standards.
Outcome Measures:
Policy adherence; average number of calories, sugar, and sodium in food products sold; revenue change.
Results:
Policy adherence increased for snacks and beverages sold by the vending machines by 89% and 98%, respectively. Average snack and beverage revenues decreased by 37% and 34%, respectively, during the sampled period.
Conclusions:
Although a 100% healthy vending policy represents a promising strategy for encouraging purchases of healthier foods, steps should be taken to counteract potential revenue changes when planning its implementation.
