Reducing Racial and Ethnic Health Care Disparities Is Essential for Better Health Care Outcomes and for Lowering Health Care Costs
There is a growing realization among healthcare researchers, clinicians, and advocates that a focus on health care disparities is an important aspect of improving healthcare outcomes and that activities toward improvement must bring together many elements of our healthcare delivery system. The populations that have customarily been underserved in the American health care system include African Americans, Latinos, Native Americans, and Asian Americans.
Defining Health Disparities
The term "health disparities" is often defined as "a difference in which disadvantaged social groups such as the poor, racial/ethnic minorities, women and other groups who have persistently experienced social disadvantage or discrimination systematically experience worse health or greater health risks than more advantaged social groups." When this term is applied to certain ethnic and racial social groups, it describes the increased presence and severity of certain diseases, poorer health outcomes, and greater difficulty in obtaining healthcare services for these races and ethnicities. When systemic barriers to good health are avoidable yet still remain, they are often referred to as "health inequities."
An understanding of how race, ethnicity, geography, education, and income impact one’s access to health services can provide valuable insight to health policy experts and advocates. Learning more about these disparities can be a way of lessening these kinds of inequalities. An analysis of the root causes of racial and ethnic disparities and what can be done to eliminate them can serve this end goal. Below are discussions of specific poorer health outcomes and ethnic and racial disparities which can be a result of social determinants. It is important to address how racial and ethnic disparities are not only morally wrong and fiscally unwise, but stress our health infrastructure, including programs such as Medicare and Medicaid.

The Elimination of Racial and Ethnic Health Disparities Would Save the U.S. Health Care System Billions of Dollars Annually
A 2011 study estimates that the economic costs of health disparities due to race for African Americans, Asian Americans, and Latinos from 2003 thru 2006 was a little over $229 billion. In a report issued in September, 2009, the Urban Institute calculated that the Medicare program would save $15.6 billion per year if health disparities were eliminated. The study examined a select set of preventable diseases among the Latino and African American communities, including diabetes, hypertension and stroke, and concluded that – if the prevalence of such diseases in the African American and Latino communities were reduced to the same prevalence as those diseases occur in the non-Latino white population – $23.9 billion in health care costs would be saved in 2009 alone.
As the representation of Latinos and African Americans in the general population increases, health care costs could be reduced even further by addressing racial and ethnic health disparities. Therefore, in addition to the compelling ethical and moral reasons to eliminate health disparities, there are economic reasons to do so as well.

Poverty, Race, and Ethnic Background Affect Access to Health Care and the Quality of Health Care
An examination of these disparities at the local and national levels is important in order to highlight the widespread nature of these health inequities.
At the national level, African American men, for instance, are more likely to die from cancer than Caucasian men. While Caucasian women are more likely to develop breast cancer than African-American women, the latter are more likely to die from this particular form of cancer than Caucasian women. While Caucasian men are more likely to develop colorectal cancer than African-American men, the latter are more likely to die from this cancer than the former. On the other hand, African-American men are more likely than Caucasian men to develop prostate cancer. The underlying causes of these disparities are socio-economic policies, health access issues among African-Americans which Caucasian persons are less likely to encounter, as well as a lack of health education.
Among America’s minority populations, race, ethnicity, and poverty are more pronounced than among Caucasian Americans. According to the US Census Bureau, in 2013, 25 percent of Hispanics, 11 percent of persons of Asian descent, and 27 percent of African Americans lived in poverty while only 12 percent of Caucasians lived in poverty. Moreover, the more impoverished one is, the more likely it is that one cannot afford health insurance. In 2012, 23 percent of “poor” and 24 percent of “lower-income” persons in the US lacked health insurance. In 2012, 26 percent of Native American/Alaska Natives, 18 percent of African Americans, 16 percent of persons of Asian descent, and 12 percent of native Hawaiian/Pacific Islanders lacked health insurance. In a 2013 study of the non-elderly uninsured, 32 percent of all Hispanics, 14 percent of all African Americans, and 6 percent of all Americans of Asian/Pacific Islander descent reported they lacked health insurance. The same study looked at all non-elderly, uninsured Americans and found that 71 percent of this population had 1 or more full time workers in the family.
The costs of health care in the United States may also impoverish many American citizens. According to a recent report, 62 percent of persons who filed bankruptcy in 2007 did so as a result of medical expenses.
Minnesota’s 2014 Health Equity Report highlights the disparate mortality rates of various races broken down by age group per 100,000 persons between the years of 2007 and 2011. For the 45 to 64 age group, 772 African American, 1,063 Native Americans, 325 persons of Asian descent, and 434 Caucasian persons died per 100,000 persons. Data from Rhode Island during the years 2011-13 shows the disparities which Hispanics and African Americans face. While 41 percent of Latinos 26 percent of African Americans reported having not having any health insurance during this time, 13 percent of Caucasians in Rhode Island reported the same information. While 31 percent of Hispanics and 22 percent of Native Americans in Rhode Island reported not being able to afford seeing a health care provider during this period, 12 percent of Caucasians reported the same information. The National Center for Health Statistics reported in March 2015 that African-American and Latino children are almost twice as likely as Caucasian children to have untreated tooth decay in primary teeth.
The numbers of Hispanics with health insurance differs nationally. In 2012, the number of uninsured Hispanics was 29 percent and in 2013 this number dipped to 24 percent.

Unaddressed Language Barriers Affect Health Outcomes and Access to Medical Care
Without effective health provider and patient communication in a language both can understand, there is an increased risk of misdiagnosis, misunderstanding about the proper course of treatment and poorer adherence to medication and discharge instructions. Health care providers from around the country have reported language difficulties and inadequate funding of language services to be major barriers to access to health care for limited English proficiency individuals and a serious threat to the quality of care they receive. In one study, over one quarter of limited English proficient patients who needed, but did not get, an interpreter reported that they did not understand their medication instructions. By comparison only 2 percent of those patients who did not need an interpreter, and 2 percent of those who needed an interpreter and received one, did not understand their medication instructions.

Children suffer from racial and ethnic health disparities
According to census figures published in 2012, 50.4 percent of all US children (31.8 million children) are identified as belonging to a racial or ethnic minority. Certain disparities in health access and outcomes are particularly noticeable for children of specific racial/ethnic minorities relative to the population at large: for Latino children, suboptimal health status and teeth conditions and problems getting specialty care; for African American children, asthma, behavior problems, skin allergies and unmet prescription needs; for Native American and Alaska Native children, hearing/visual problems, no usual source of care and unmet medical/dental needs; and for Asian/Pacific Islander children, problems getting specialty care and not seeing a doctor for the past year. According to the 2013 US Census, around 11-12 percent of persons under age 19 with household incomes less than $50,000 per annum were without health insurance. 27 percent of non-native born persons under 19 were without health insurance in 2013. During that same year, 12 percent of Hispanics under the age of 19, 7 percent of African Americans under the same age, and 8 percent of persons under the age of 19 of Asian descent lacked health insurance.

Obesity and Chronic Health Conditions Are Caused in Part by Inadequate Access to Fresh Food
According to a 2012 study, nearly 19 percent of all African American adults over the age of 20 have diagnosed or undiagnosed diabetes. Additionally, African Americans are 77 percent more likely than non-Hispanic Caucasian Americans to develop diabetes. On the other hand, nearly 12 percent of Hispanic Americans have diagnosed or undiagnosed diabetes and Hispanics are 66 percent more likely than non-Hispanic Caucasians to have diabetes.
It has been established that public health strategies designed to improve social and physical environments to create conditions for healthful eating and physical activity can be, in addition to clinical treatment, beneficial for those who are already obese. As an example, "innovative public policy approaches include a variety of policy and environmental initiatives designed to increase fruit and vegetable consumption in underserved areas." Thus, elimination of "food deserts" (see below) in underserved communities can help eliminate chronic diseases, such as diabetes, and help achieve greater equity in health outcomes among racial and ethnic minorities.

Food Deserts Result in Poorer Health Outcomes
There are places in the United States which lack supermarkets which are accessible to neighborhood residents nor served by adequate public transportation. Residents of these neighborhoods must rely on small grocery stores or convenience stores, which carry few – if any – fresh fruits and vegetables. Areas where people have poor access to fresh and healthy food are sometimes known as "food deserts." People who live in food deserts are aware of their lack of accessibility to fresh fruits and vegetables and indicate in surveys a desire to have good access to fresh produce. Thus, unhealthy eating is often the result of structural inadequacies in accessing healthy foods and not necessarily limited to personal dietary choices.
The connection between healthy diets and good health outcomes is well established. This is readily seen, for example, with respect to diabetes and hypertension, two chronic – and preventable – diseases that disproportionately affect ethnic and racial minorities. Thus, the existence of "food deserts" contributes to the continuation of racial and ethnic health disparities. Small scales measures designed to improve access to healthy foods can help change dietary habits. The resulting change in diet for residents of former food deserts leads to better health outcomes and contributes to eliminating ethnic and racial health disparities.
A 2014 study shows that providing access to healthy food does not necessarily mean, however, that eating habits change or that obesity drops in the community. Policymakers must also address how healthy food is perceived.

Limited Transportation to Health Facilities Can Affect Health Outcomes
Costs of living, geographical proximity to health facilities, patient health, socio-economic factors, as well as race might singularly or in concert affect a patient’s access to adequate health services. In some instances, there are options for patients who are not able to drive to be driven to, or to take public transit to a health facility.

Although it is commonly believed that health disparities occur simply because of a lack of health insurance and access to health care, disparities exist even after access to the health care system has been improved. New studies have shown, for instance, that there are stark differences in health outcomes of African American and Caucasian patients with the same conditions even when they are treated by the same doctor. Studies have also shown that diagnoses, treatments, and quality of care can vary greatly depending on a number of factors which affect minority communities including language barriers, lack of insurance coverage, and differential treatments based on the population group.
Racial and ethnic minorities are among the fastest growing of all communities in the U.S. and comprised approximately 39 percent of the total U.S. population in 2013. Yet data on health status point to significant evidence of poorer health outcomes among racial and ethnic minorities with respect to death and preventable disease. The challenge for the U.S. is to address adequately poor racial and ethnic minority health status and persistent racial and ethnic health disparities at a time of rapidly increasing racial and ethnic diversity.

 Vehicle access is perhaps the most important determinant of whether a family can access affordable and nutritious food. Thus, for the total U.S. population, between 2.3 and 5.5 percent of all households may be outside of a walking distance to a supermarket and may lack access to a vehicle. Not surprisingly, the percentage of households without access to vehicles is higher in low-income areas.

Pages 3, 6, 15, 18-20.
 Ibid. Page 11.
 Ibid. Page 57. Low-access to supermarkets is most heavily influenced by characteristics of neighborhood and household socioeconomic environments, such as the extent of income inequality, racial segregation, transportation infrastructure, housing vacancies, household deprivation, and rurality. This lends support to the notion that there is indeed a socioeconomic “contextual effect” that should be considered when designing food access policy.
