The Health Equity Framework: A Science- and Justice-Based Model for Public Health Researchers and Practitioners

In this article, we describe a science- and justice-based framework for promoting health equity designed for researchers and practitioners working across public health and social science fields. We developed the health equity framework (HEF; etr.org/healthequityframework) in two phases of iterative development. Building on existing models, the HEF illustrates how health outcomes are influenced by complex interactions between people and their environments. The framework centers on three foundational concepts: equity at the core of health outcomes; multiple, interacting spheres of influence; and a historical and life-course perspective. Health equity is defined as having the personal agency and fair access to resources and opportunities needed to achieve the best possible physical, emotional, and social well-being. By centering population outcomes, the HEF encourages researchers and practitioners to think beyond traditional approaches that focus on individual behaviors and choices to assess and identify their gaps in acknowledging and addressing factors from multiple spheres of influence. We identified four, interacting spheres of influence that represent both categories of risk and protective factors for health outcomes as well as opportunities for strategies and interventions that address those factors. The HEF highlights the explicit and implicit interactions of multilevel influences on health outcomes and emphasizes that health inequities are the result of cumulative experiences across the life span and generations. The HEF is a practical tool for leaders and professionals in public health research and practice to reflect on and support a shift toward addressing health inequities resulting from the interplay of structural, relational, individual, and physiological factors.
