There are large and persistent disparities between the health status of Blacks and Whites in the United States. On average, the mental and physical health of Blacks is much poorer than Whites. In this article, we discuss several potential direct causes of Black–White disparities in health status, which include biological or genetic factors, prejudice and related processes, and socioeconomic factors. We also consider how the system-level, patient-level, and provider-level components of healthcare contribute to disparities in health status. We examine in detail the psychological processes associated with patient- and provider-level factors that may produce healthcare disparities. Of particular interest is the potential impact of racial attitudes and stereotypes on provider–patient interactions. Finally, we propose possible directions for future research on health disparities and discuss policy changes that might reduce disparities in health status and healthcare between social groups.
