Social exclusion and its impact on health over the life course: A realist review protocol

Abstract

Background: Social exclusion is a process whereby certain individuals are born into or pushed to the margins of society and are unable to participate in social, cultural, economic, and political life. People who experience social exclusion are not afforded the same rights and privileges as other population groups. Socially excluded people often experience poorer outcomes in a variety of domains including health, education, employment, and housing than people of a higher social standing. People experiencing social exclusion frequently have higher and more complex health needs and poorer access to healthcare than the general population. The aim of this study is to better understand and explain how social exclusion occurs and how it impacts health over the life course. Methods: A realist review will be undertaken. Data will be collected via a systematic search of peer-reviewed databases and further iterative searches of peer-reviewed and other literatures as needed. The following data bases will be searched: MEDLINE, Embase, CINAHL, and ASSIA, using both indexed subject headings in each database and relevant key words. Grey literature will be searched via Google Scholar and relevant websites of organisations that work with populations affected by social exclusion. Conclusion: A realist review will be conducted to explain the underlying societal mechanisms which produce social exclusion and related health outcomes in particular contexts affecting excluded population groups across the life course. The study has the potential to inform policy makers and service managers of how and why social exclusion occurs and potential key intervention points to prevent exclusion from happening.
