To evaluate the potential impact of a 100% healthy vending machine nutrition policy.
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.
County of Los Angeles facilities, 2013-2015.
Vending machines in facilities located across Los Angeles County.
A healthy vending machine policy executed in 2013 that required 100% of all products sold in contracted machines meet specified nutrition standards.
Policy adherence; average number of calories, sugar, and sodium in food products sold; revenue change.
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.
