The issue of health disparities has been a hot topic in medicine, fueled in recent years by the 2002 Institute of Medicine report, Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care. That report, and the multitude of studies preceding and following it, have made it clear that health disparities are all too common and their origins multifactorial. In Health Disparities in the United States: Social Class, Race, Ethnicity, and Health, Donald Barr effectively summarizes a substantial amount of data that illuminate where the inequalities lie, what the foundations are, and how to reduce these disparities.
