ABOUT MDRs

A cause of health inequality in Middle-Class Black people

There are persistent and pervasive disparities in the health of Black people compared to non‐Hispanic Whites in the United States. There are many reasons for this gap; “Marginalization-Related Diminished Returns (MDRs)” is one of the mechanisms behind racial health disparities in middle-class people of color. MDRs refer to a phenomenon wherein the health effects of certain socioeconomic resources and psychological assets are systematically smaller for Blacks compared to Whites. These patterns are robust, with similar findings across different resources, assets, outcomes, settings, cohorts, and age groups. However, the role of diminished gain as a main contributing mechanism to racial health disparities has been historically overlooked. Societal barriers that created by structural racism are responsible for MDRs.
