What needs to happen to 'level up' public health?

The aim of this article is to examine what needs to happen in central, sub-regional and local government to 'level up' public health in the United Kingdom (UK). The Government's recent White Paper outlined ambitious targets for reducing regional disparities, including a 'mission' to tackle inequalities in healthy life expectancy and reduce inequalities in the social determinants of health outcomes. However, the approach has been criticised for failing to integrate population health policy objectives, programmes and interventions into the implementation of the levelling up agenda and its associated 'missions'. Drawing on a case study of promoting healthy urban development in the UK, we examine how the wider determinants of health might be incorporated into the Government's levelling up strategy. Based on in-depth interviews with 132 urban development actors, our findings reveal that long-term investment in healthy urban development could play a key role in levelling up public health but is not currently part of the Government's plans. We make a timely contribution to the levelling up debate by placing public health centre stage in social science debates. We conclude by offering a series of recommendations for transformative policy change to level up health.
