Introduction
Over 70% of premature deaths worldwide can be attributed to non-communicable diseases (NCDs), notably cardiovascular disease, cancer, diabetes, dementia, chronic respiratory disease, mental health problems and related conditions such as obesity. The majority of premature NCD deaths are preventable, being principally caused by the consumption of the products of the tobacco, alcohol, gambling and ultra-processed food and drink products industries.1–3 These have been collectively referred to as the unhealthy commodity industries (UCIs), defined as industries or groups of corporations where a significant share of their product portfolio comprises unhealthy commodities with high profit margins aimed at, and easily accessible to, large numbers of consumers.4–6 The gambling industry has received less attention than other UCIs as a driver of NCDs, but research is expanding rapidly showing that gambling is associated not just with alcohol and drug problems, but also depression and anxiety.2 3 7–9 The harm from gambling is now comparable with that associated with alcohol misuse in high-income countries.10 The United Nations (UN) and the World Health Organization (WHO) have coordinated global commitments to NCD prevention over recent decades.11 However, implementation of effective solutions remains limited. A key barrier has been the continued close involvement of UCIs in public health policy-making.12 13
Public health governance is broadly defined as the set of functions ensuring authority (including scientific knowledge), resources, policy development, continuous evaluation and improvement, and effective collaboration on public health issues.14 This policy arena is characterised by an increasingly diversified and complex system of decision-making,13 with an often symbiotic relationship between states and non-state actors, including corporations.15 One rationale for the involvement of UCIs in public health governance is that those affected by policies should be allowed to contribute to their formulation.16 This may be problematic for a number of reasons. First, it is based on the premise that the power to influence policy debates is reasonably equally distributed across interest groups; this cannot be assumed where multinational corporations have vast influence, often with annual turnovers exceeding those of many national economies.17 Second, evidence indicates that corporations whose products are damaging to health have deliberately and collectively pushed for these forms of governance, encouraging policy-making structures that embed corporate influence and a reliance on corporate evidence specifically in order to prevent public health policies that might threaten profits.18–20 Evidence also shows how they have used those systems, for example, to overwhelm public consultations and to submit misleading evidence.21 22 Any potential benefits of UCI involvement in public health policy are therefore strongly contested due to the differences between their corporate interests and public health goals.4
This study sits within the overarching domain of, and contributes to research on, the ‘commercial determinants of health’, variously defined as adverse health impacts attributable to commercial activities and strategies employed by UCIs to promote products which can damage health.23–25
There is growing evidence of convergence of strategic approaches between UCIs themselves,26 27 and the need for a systems approach to conducting research on UCIs’ influence of public health policy. Doing so would conceptualise poor health as the result of many factors—such as UCIs' shaping of policy—as interconnected elements working together to bring about change throughout the system.28 A complex systems approach to understanding the commercial determinants of health draws upon a range of methods to design, implement and evaluate interventions at a systems level to improve public health;29 it can help explore how UCIs position themselves in the complex process of public health decision-making and how they legitimise their presence there. It can encourage public health researchers to integrate mixed methods from a variety of sources and disciplines including quantitative and qualitative traditions.30 31 A systems approach to research on UCIs offers an analytical framework within which to explore not only the conditions and factors shaping the commercial determinants of health, but also, importantly, the way in which these factors relate to each other and how they generate environments which negatively affect health.25
This paper explores the links between UCIs, analyses the extent of alignment across their corporate political strategies and proposes a cohesive systems approach to research across UCIs.
