App-based delivery platforms and exposure to (un)healthy food and drink environments

A 2020/2021 Summer Studentship research project

Student: Cassian Duthie
Supervisors: Dr Rose Crossin, Ms Christina McKerchar
Sponsor: University of Otago, Division of Health Science


Exposure to unhealthy and health promoting food and alcohol environments have typically been measured using distance based exposure methods, for different neighbourhoods. The growth of app based, on demand delivery thorough services such as Ubereats and Deliveroo, potentially removes the distance factor and exposes a broader population to healthy and unhealthy food options. Based on a typology of delivery services this project will review the current literature surrounding app based delivery of food and alcohol, the impacts on exposure, the policy and regulatory implications, and health outcomes.


This project will help support a wider project currently under development in the Department of Population Health and will support a grant application in the department. It is likely to have policy impact in terms of helping to inform licencing and other regulatory decisions.


Search terms will be developed and a critical review of the literature undertaken, based on a typology of food and alcohol delivery services.

Student researcher’s component of the study

The student will assist with developing a typology of services, and set search terms in conjunction with supervisors. The student will undertake the review of literature.

Student prerequisites

Familiarity with literature reviews would be beneficial but not essential.
