An environmental scan of food and drink advertising on public transport around Adelaide schools

Abstract Issue Addressed Children and adolescents are particularly receptive to cues from food and drink advertising. Several policies recommend restricting unhealthy or discretionary (‘junk’) food advertising on government infrastructure such as public transport. Prior research in New South Wales (NSW) and Western Australia (WA) reveals a high proportion of discretionary food advertising outdoors and on public transport. The aim of this study was to identify the landscape of food and drink advertising on public transport assets around Adelaide schools. Methods An environmental scan of food and drink advertising on public transport assets within 500 m of 65 Adelaide schools was conducted. The Council of Australian Governments Health Council's interim guide was used to categorise advertisements as ‘suitable’ or ‘unsuitable’ for promotion. Results Almost four in every five food and drink advertisements on public‐transport assets observed around Adelaide schools included discretionary food or drink, and therefore were categorised as unsuitable for promotion. Advertisements on bus exteriors were more likely to promote discretionary foods, compared with bus shelters. Conclusions This proportion of ‘unhealthy’ food advertising was comparable to previous research conducted in WA and NSW. So What? In light of historic state/territory actions such as the ACT preventing discretionary food advertising on public transport, these findings should prompt a review and discussion of the suitability of food and drink promotion on government‐owned South Australian transport and their associated assets.
