Health Disparities


Health disparities includes disparities in health status attributable to racial, ethnic, and cultural barriers to access. Five determinants of population health are generally recognized in the scientific literature: biology and genetics (e.g., sex), individual behavior (e.g., alcohol or injection drug-use, unprotected sex, smoking), social environment (e.g., discrimination, income, education level, marital status), physical environment (e.g., place of residence, crowding conditions, built environment [i.e., buildings, spaces, transportation systems, and products that are created or modified by people]), and health services (e.g., access to and quality of care, insurance status). Thus, observed health disparities typically have more than a single cause.

In general, the limited evidence available for the first half of the 20th century indicates that mortality differentials by socioeconomic status narrowed sometime between 1900 and the 1930s or 1940s. More recent data covering roughly the second half of the 20th century indicate that mortality differentials by socioeconomic status have generally widened from around the 1950s or 1960s through the 1990s.

Economic Impact of Health Disparities

  • The Office of Minority Health and Disparities has a series of fact sheets on six major focus areas in which racial and ethnic minorities experience serious disparities in health access and outcomes, including cancercardiovascular diseasediabetesHIV/AIDSimmunizations, and infant mortality. These six health areas were selected for emphasis because they reflect areas of disparity that are known to affect multiple racial and ethnic minority groups at all life stages. The fact sheets contain basic information about the burden (health and economic) associated with each area.
  • There are four other major diseases and conditions that disproportionately impact racial and ethnic minorities, including mental health, hepatitissyphilis, and tuberculosis. OMHD fact sheets have been developed for mental healthtuberculosis, and lupus.
  • At least some of the foregoing disparities relate to racial and ethnic disparities in tobacco use.
  • Kristin SuthersEvaluating the Economic Causes and Consequences of Racial and Ethnic Health Disparities. American Public Health Association, Issue Brief. November 2008. This report discusses the economic impact of disparities at the level of the individual and society, but provides no hard dollar estimates for the U.S.
  • The following articles have quantified the costs in the U.S. for each year of life lost due to health disparities and the resulting economic burden:
    • Timothy WaidmannEstimating the Cost of Racial and Ethnic Health Disparities.  The Urban Institute (September 2009). Disparities among African Americans, Hispanics and non-Hispanic whites cost the health care system $23.9B in 2009. Of this, Medicare will finance $15.6B while private health insurers will cover $5.1B.
    • Thomas A. LaVeistDarrell J. Gaskin, and Patrick RichardThe Economic Burden of Health Inequalities in the United States.  Joint Center for Political and Economic Studies (September, 2009).  In 2008 dollars, the annual health-related costs of disparities exceed $76B; annual productivity losses related to disparities amount to $401B (95% of this relates to the costs of premature death). More than 30 percent of direct medical costs for African Americans, Hispanics and Asian Americans represent excess costs attributable to health disparities.
