Expanding the frame of understanding health disparities: from a focus on health systems to social and economic systems.

Policy makers are increasingly attending to the problem of racial and ethnic health disparities, but much of this focus has been on evidence of inequality in health care systems. This attention is important and laudable, but eliminating inequality in the health care system would be insufficient to eliminate racial and ethnic disparities and improve the health of all Americans. Social and economic factors, such as disadvantaged socioeconomic status, racism, discrimination, and geographic inequality shape virtually all risks for poor health. Interventions that focus solely on improving access to health care, or on reducing individual behavioral and psychosocial risks, therefore have limited potential to reduce racial and ethnic health disparities. The elimination of health disparities requires comprehensive, intensive strategies that address inequality in many sectors, including housing, education, employment, and health systems. These interventions must be targeted at many levels, including individuals and families, workplaces, schools, and communities.
