Social policies as determinants of health: new evidence, ongoing challenges, and future pathways

Abstract

Despite acknowledgment that social and economic policies fundamentally shape health, persistent geographic and sociodemographic inequities in the United States reflect the deliberate choices embedded in policy decisions. There is a critical need for policy research that illuminates not just associations of social policies with health, but also mechanisms and pathways to equitable impact. The special collection of articles in Health Affairs Scholar on “Intersections of Social Policies and Health” advances the field by examining how the effects of social policies are shaped by legal, political, and cultural contexts; the uneven implementation and enforcement that contribute to health disparities; and the crucial role of narratives and administrative processes in mediating policy impact. Through nuanced analyses—such as exploring policy ecosystems, administrative burdens, and media framing—these studies move beyond single-policy assessments to explore the complex realities of translating policy intent into population health improvements. Collectively, the collection points toward new research priorities: advancing nuanced measurement of policy contexts, integrating equity and subgroup analyses, prioritizing implementation science, incorporating political and narrative determinants, and embracing intersectoral approaches. By deepening our understanding of how and why policy effects unfold unevenly, this scholarship charts a course for more effective and equitable policy research and action.
