The Dahlgren-Whitehead model of health determinants: 30 years on and still chasing rainbows

Abstract

This year marks the 30th anniversary of the Dahlgren and Whitehead model of the main determinants of health, sometimes known as 'The Rainbow Model'. In this article, we reflect on developments over those thirty years before going on to look to the future. We start by telling the story of our model's idiosyncratic journey from initial rejection to worldwide acclaim. We reflect on the many ways in which the model has been used over the years and why it has proved illuminating for people in so many different positions. It is equally important to understand what it does not do and what it was never intended to do, as sometimes the conceptual debate gets side-tracked by mistaken assumptions. We take some space to outline how we ourselves use the model with the complementary Diderichsen Framework to explain the pathways and mechanisms by which the known determinants of health bring about the social gradients in health that are observed within countries. We conclude by looking to the future and what further needs to be done to capture insights for action on the determinants and drivers of health and of growing inequalities in the post-pandemic world.
