Why Social (Political, Economic, Cultural, Ecological) Determinants of Health? Part 1: Background of a Contested Construct.

This article is the first half of a 2-part essay on the Social Determinants of Health (SDOH) as a field of scientific inquiry and theoretical framework, exploring its historical roots, current applications, and the controversies that surround it. Part 1 (this article) discusses the background and rationale of the SDOH framework, whilst part 2 (forthcoming) will analyze the current alternatives to this framework. The authors analyze the debate surrounding the contested term "social" in the field of health equity, through a clarification of the terms "social" and "social systems" and providing an alternative model through realist semantics and ethics. Despite the misunderstandings of the term "social," the authors argue that SDOH remains a useful umbrella term to capture the political, economic, cultural, and ecological determinants of health. Through this essay, the authors outline the reasons behind our decision to change this journal's title from International Journal of Health Services to International Journal of Social Determinants of Health and Health Services.
