A theoretical perspective on why socioeconomic health inequalities are persistent: building the case for an effective approach

Despite policy intentions and many interventions aimed at reducing socioeconomic health inequalities in recent decades in the Netherlands and other affluent countries, these inequalities have not been reduced.

Based on a narrative literature review, this paper aims to increase insight into why socioeconomic health inequalities are so persistent and build a way forward for improved approaches from a theoretical perspective.

Firstly, the authors present relevant theories focusing on individual determinants of health-related behaviors. Thereafter, they present theories that take into account determinants of the individual level and the environmental level. Lastly, they show the complexity of the system of individual determinants, environmental determinants and behavior change for low socioeconomic position (SEP) groups and describe the next steps in developing and evaluating future effective approaches. These steps include systems thinking, a complex whole-system approach and participation of all stakeholders in system change.
