The use of contracts to implement and manage healthy vending: best practice recommendations for effective and sustained interventions

To be effective, contracts used to manage healthy food vending should include more than the nutrition standards for healthy food and drinks. Clearly stating the contract objectives, operative terms and conditions, and defining responsibilities for monitoring, review and enforcement within the contract, in addition to the nutrition standards, will assist practitioners in creating effective and sustained contract-based initiatives aimed at improving the healthiness of vending, or potentially other food retail environments.
