Summary
This health economic modelling study estimates the potential population-level impacts of the Transport for London HFSS advertising ban, which came into force in 2019. Using modelled data on advertising exposure, purchasing behaviour and downstream health outcomes, the study suggests the policy is likely to generate meaningful reductions in diet-related disease burden and associated healthcare costs. The study also examines equity dimensions, assessing whether health gains are distributed proportionately across socioeconomic groups.
UK applicability
This study is directly applicable to UK policy, being based entirely on the TfL network and the London population. The findings are relevant to local authorities, public health bodies and national policymakers considering similar HFSS advertising restrictions in other transport and public space settings across the UK.
Key measures
Changes in HFSS food purchases and consumption; quality-adjusted life years (QALYs); healthcare cost savings; distributional equity impacts by socioeconomic group; disease incidence estimates (e.g. obesity, cardiovascular disease, type 2 diabetes)
Outcomes reported
The study modelled the projected health, cost and equity impacts of restricting high fat, salt and sugar (HFSS) product advertising across the Transport for London (TfL) network, estimating changes in dietary intake, disease burden and health inequalities across population subgroups.
