Prevalence of disease – trends, projections, risk factors and actions

In 2023, we have embarked on a new programme of work which explores: 

  • Disease trends 

  • 10-year disease projections 

  • Risk factor trends 

  • Evidence-based interventions across the full range of public health responses 

  • The impact of these on costs to the health system 

This builds on and updates Health and its determinants in Wales (2018). Our analysis will drive our priorities. Topics we will explore include: 

We will add further information as the work progresses. This includes information on how we are working with our partners across the system to bring together evidence-based action to improve the health and well-being of the people of Wales. 



We welcome feedback on this or on any of our other work at
