The Urban Stress Model: a framework for understanding the persistence of health disparities in cities

Using an equity lens, we introduce the Urban Stress Model (USM), rooted in the history and experience of New York City (NYC), the most unequal large city in the United States. The USM is a novel, generalizable framework for understanding how fundamental structural characteristics of cities shape health through chronic stress pathways. It moves beyond past frameworks to center the lived experiences of historically marginalized urban populations while highlighting the precise stress pathways that not only lead to poor health, among these populations and in the general urban population, but also perpetuate health inequity. Using NYC as an illustrative case, we demonstrate how USM explains the persistence of urban health disparities. We trace the historical socio-political foundation of inequality in NYC that continues to shape contemporary health outcomes, then apply USM to diabetes, a condition intimately linked to both stress and urbanization. Our model proposes that the chronic stress of social disadvantage is amplified by urban hazards and that city form compounds this stress burden. This high stress setting heightens diabetes risk and more generally creates the pervasive disparities observed in NYC and other urban centers. We conclude by outlining multi-level intervention solutions grounded in urban planning and public health scholarship.
