Abstract

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.
