A discourse network analysis of the public media debate on the UK Soft Drinks Industry Levy

Abstract

Abstract Background On 6th April 2018, the UK Government introduced the Soft Drinks Industry Levy (SDIL) as a policy designed to reduce population level sugar consumption and related illnesses. Given that the successful introduction of upstream food and nutrition policies is a highly political enterprise involving multiple interested parties, understanding the complex network of stakeholders seeking to influence such policy decisions is imperative. Methods Media content analysis was employed to build a data set of relevant articles from UK national newspapers. Articles were analysed to identify stakeholder agreement or disagreement with defined concept statements. We used discourse network analysis to produce visual representations of the stakeholder network and coalitions evident in the debate, leading up to and following the announcement of the SDIL. Results We identified 3,883 statements made by 214 individuals from 176 organisations, relating to 47 concepts. Visualisations revealed a complex network of stakeholders with two discourse coalitions. Polarisation arose from 3 factors: (i) differences in political ideology; (ii) position on the specific policy option; (iii) interpretation of the evidence. Industry stakeholders appeared less united before the SDIL announcement. Some industry actors appeared in the supportive coalition, possibly due to the use of corporate social responsibility rhetoric. Jamie Oliver was a dominant supportive stakeholder, suggestive of his role as a policy entrepreneur. Conclusions This study illustrates the complexity of the network of stakeholders involved in the public debate on food policies such as sugar tax and the SDIL. Public health advocates seeking to gain support for future upstream regulation to promote population health would benefit from tailoring their communication to take advantage of sources of polarisation. Vocal celebrity policy entrepreneurs may be instrumental to facilitate alignment of stakeholders around a clear ideology. Key messages This study provides a novel insight into the network of stakeholders involved in public debates on food policies. Public health advocates may benefit by identifying and aligning with a clear ideology.
