Regulatory mechanisms to create healthier environments: planning appeals and hot food takeaways in England

Measuring the association between the opening of a new multi-national restaurant with young people's eating behaviours

Out-of-home eating (takeaway, take-out and fast-foods) is associated with intakes of higher energy and fat, and lower intakes of micronutrients, and is associated with excess weight gain. In 2017, a unique opportunity arose to measure the association between the opening of a new multi-national fast-food restaurant (McDonald's) and consumption of fast-food on young people aged 11-16. This study uses a repeated cross-sectional design to explore group level change over time with respect to out-of-home eating behaviours of young people. Two secondary schools in Redcar and Cleveland agreed to participate and facilitated the completion of a questionnaire on their pupils eating behaviours at three timepoints a) prior to the new restaurant opening, b) three months post-opening and c) nine months post opening. Reported frequency of visits to McDonald's showed a statistically significant increase in visits between 3 and 9 months of the restaurant opening. This research asks and explores the question of whether the introduction of a new multi-national fast-food restaurant influences eating habits of young people attending schools near the new outlet.

Planning guidance to limit hot food takeaways: Understanding the possible economic impacts

Local and national policymakers are seeking innovative solutions to create healthier food environments around the world. Between 2009 and 2017, 35 local authorities across England (UK) adopted planning guidance designed to limit the proliferation of hot food takeaways near schools. Whilst these policies are intended to improve population health, they are also likely to have economic impacts. Often a decision to introduce such policies comes down to consideration of whether the short-term economic imperatives of allowing new takeaway outlets to open outweighs the potential long-term public health implications and associated economic consequences. These potential negative and positive economic impacts have not previously been clearly described and are summarised here. The aim of this paper is to provide an overview of the potential economic impacts of takeaway management zones. In particular, we present a Causal Loop Diagram (CLD) that outlines the possible economic impacts of takeaway management zones based on researcher knowledge of the interventions and the industry. Potential negative impacts fall across sectors and may include a loss of employment opportunities and reductions in local and national tax receipts, and may impact the economic vitality of local communities. In the longer term, there is the potential for positive impacts such as reductions in healthcare resource utilisation, social care expenditure and sickness-related absence from work. Part of a robust case would a better economic understanding, that would enable local authorities to improve understanding of the trade-offs associated with the policy, such as short-versus long-term, and business-related versus society-related health benefits and costs.

Changes in the number of new takeaway food outlets associated with adoption of management zones around schools: A natural experimental evaluation in England

By the end of 2017, 35 local authorities (LAs) across England had adopted takeaway management zones (or "exclusion zones") around schools as a means to curb proliferation of new takeaways. In this nationwide, natural experimental study, we evaluated the impact of management zones on takeaway retail, including unintended displacement of takeaways to areas immediately beyond management zones, and impacts on chain fast-food outlets. We used uncontrolled interrupted time series analyses to estimate changes from up to six years pre- and post-adoption of takeaway management zones around schools. We evaluated three outcomes: mean number of new takeaways within management zones (and by three identified sub-types: full management, town centre exempt and time management zones); mean number on the periphery of management zones (i.e. within an additional 100 m of the edge of zones); and presence of new chain fast-food outlets within management zones. For 26 LAs, we observed an overall decrease in the number of new takeaways opening within management zones. Six years post-intervention, we observed 0.83 (95% CI -0.30, -1.03) fewer new outlets opening per LA than would have been expected in absence of the intervention, equivalent to an 81.0% (95% CI -29.1, -100) reduction in the number of new outlets. Cumulatively, 12 (54%) fewer new takeaways opened than would have been expected over the six-year post-intervention period. When stratified by policy type, effects were most prominent for full management zones and town centre exempt zones. Estimates of intervention effects on numbers of new takeaways on the periphery of management zones, and on the presence of new chain fast-food outlets within management zones, did not meet statistical significance. Our findings suggest that management zone policies were able to demonstrably curb the proliferation of new takeaways. Modelling studies are required to measure the possible population health impacts associated with this change.
