This study examines how implementation of a healthy vending policy in Carson, California, changes the types of beverages that are available in park vending machines. The study design is a pre-posttest with post-only comparison group. The main outcome is proportion of beverages in vending machines that is consistent with caloric and sugar content guidelines for children as defined by the Nutrition Environment Measures-Vending (NEMS-V) tool. This study finds that prior to implementation of the vending policy, 70% of the beverages did not meet NEMS-V guidelines, on average. After implementation of the vending policy, this number declined to 7%. This study suggests that healthy vending policies can have an impact on the types of beverages that are available in city parks. This report examines the effect of health vending policies on the beverage quality of municipal parks in Carson, California. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.
