Public health is an important but sometimes overlooked facet of the medical system. Whereas doctors typically treat a person’s medical symptoms after they become ill, public health is concerned with the
prevention of illness and injury in communities. Public health practitioners work closely with communities to determine the root causes of sickness and investigate how illness and injury are related to social, political, and cultural factors. Though many of the people who work in public health have some form of formalized medical training (e.g., nurses, doctors, first responders), public health also includes social workers, government officials, sanitation workers, and cultural and religious leaders.
Public health practitioners have been instrumental in combating the community spread of
COVID-19 by encouraging people to get vaccinated, advocating for safe and sanitary working conditions, and promoting the wearing of masks and other preventive measures that slow the spread of the virus. Importantly, public health practitioners have also been instrumental in showing how different racial, ethnic, religious and cultural communities are affected by public health crises like COVID-19.
Illnesses and injuries do not affect all communities the same way — a person’s race, ethnicity, gender, sexuality, and religious or cultural beliefs can play a role in how susceptible they are to certain illnesses or how they react to getting sick. Though there may be a biological basis for some of these differences, many of the disparities in health outcomes for different communities are caused by
social determinants.
The Connection Between Discrimination and Public Health Outcomes
One such social determinant is discrimination. There is a
proven disparity between the health outcomes of Black and white Americans, as well as between white Americans and Hispanic and Indigenous Americans. Racial and ethnic minorities have been consistently shown to have a higher infant and adult mortality rate than white Americans, and racial and ethnic minorities also suffer from certain diseases -- such as hypertension and high blood pressure -- at a rate higher than white Americans. The reasons for these disparities are not biological; they can be traced back to the individual and institutionalized experiences of discrimination that marginalized communities face.
Discrimination refers to the unequal (and usually negative) treatment that marginalized people and groups experience both on an individual and structural level. A person may be discriminated against based on their racial, ethnic, cultural or gender identity (or any other minority identity) in the form of hostile acts such as
hate crimes and
identity-based harassment. However, there are also structural forms of discrimination, such as racial and gender inequity in
hiring practices and
housing discrimination.
The individual and structural experiences marginalized people have with discrimination can create numerous negative health outcomes, and it can also make it harder for them to get diagnosed correctly and receive quick and effective treatment. Poor health outcomes for marginalized people are likely related to the
stress that experiences of discrimination cause, as well as lack of access to resources such as fresh and healthy foods, safe places to exercise and preventive medical care.
The relationship between discrimination and health can thus be connected to both the negative individualized emotional responses that stress generates — such as distress, fear and sadness — and the decreases in quality of life created by institutionalized discrimination. Lack of access to safe housing, good jobs and education, as well as the
higher rates of criminalization that many marginalized communities experience, can lead to problems such as substance use disorder, anxiety disorders and depression. For example, Black Americans living below the poverty line are
twice as likely to report experiencing serious psychological distress than those living above the poverty line.
Because discrimination is
bad for public health, many public health practitioners and organizations, including the Center for Disease Control and Prevention (CDC), have called for an increased focus on combating racism and other forms of discrimination in health care. A diverse public health workforce comprised of people who know, firsthand, how harmful discrimination is will be necessary to address the far-reaching health effects of inequality — but the public health field still has a ways to go in building this workforce.
Diversity and Inclusion in Public Health
The U.S. population is becoming more racially, ethnically and culturally diverse. According to the
United States Census Bureau, 50% of children younger than 5 belonged to racial or ethnic minority groups in 2017. However, even as the country’s demographics change, discrimination — including in health care — remains a major issue. Racial and ethnic minorities are still at a greater risk than white Americans of experiencing negative health outcomes from health conditions that are preventable and treatable. These negative health outcomes are connected to forms of structural discrimination such as income inequality, housing inequality and educational inequality.
There are
many barriers to marginalized groups getting access to effective, quick and safe medical treatment. One such barrier is that health care professionals and public health practitioners tend to be
less diverse than the populations they serve. 42% of the governmental public health workforce identifies as racial or ethnic minorities, but the majority of people within the populations public health professionals work with tend to be people of color (POC). Lesbian, gay, bisexual and transgender people also tend to be
underrepresented in the public health field.
The underrepresentation of minorities in public health is important because research shows that public health practitioners who have marginalized identities are
better equipped to serve clients who come from marginalized communities. Marginalized clients are also more likely to trust services provided by people who come from similar backgrounds. For instance, Black Americans have been shown to have better
health outcomes after working with Black doctors, who are more likely to understand Black Americans’ experiences of racism.
The lack of diversity in the public health field stems from multiple root causes. First, there is a
pipeline issue in public health education, meaning that some marginalized groups are underrepresented in health care and public health care education. Hispanic Americans, for example, make up just
6% of students in public health programs even though 12% of the U.S population is Hispanic. The underrepresentation of some groups in public health may be compounded by the fact that many public health jobs require a master’s degree, and funding for graduate programs in public health tends to be minimal, making programs less accessible to people without economic means.
There is also an underrepresentation of marginalized groups in health care leadership. A
research study on 200 global health organizations found that 70% of organizational leaders are men. Further, in state and local health departments, white Americans hold the
majority of leadership positions, whereas POC are overrepresented in administrative and clerical positions. The lack of marginalized people leading public health organizations can lead to blind spots that may affect these organizations’ ability to serve marginalized communities.
Finally, there may be a general
lack of knowledge among young people about public health careers. Public health is rarely emphasized in high school curriculums, and many students interested in health may opt to pursue more lucrative medical careers by becoming physicians or medical researchers.
Whatever the reason for lack of diversity in public health, there are concrete actions public health educators and leaders can take to increase the diversity of the public health workforce and thus create a public health field better prepared to prevent the negative health outcomes caused by discrimination.
Increasing Diversity in the Public Health Workforce
Creating a more diverse public health workforce starts with
improving access to public health education for marginalized communities. To do this, universities with public health programs can start doing
targeted recruitment to make marginalized students more aware of opportunities in public health. Along with targeted recruitment, universities can provide more financial support to underrepresented students, as well as more
mentorship opportunities. Further, public health curriculum could be
expanded to more undergraduate programs so that students are exposed to the field earlier and with more economic support. Finally, increasing the diversity of public health programs will require
collaboration between university administration, program faculty, students and organizations hiring public health professionals to ensure that diversifying the field is a central concern.
There are also changes that can be made at the
leadership level within public health organizations to better support a diverse workforce. Public health care organizations can
adopt new organizational norms that affirm and emphasize the importance of racial, ethnic, cultural and gender diversity to public health work. They can also improve their
hiring and retention strategies, making a concerted effort to recruit people from underrepresented groups for leadership positions and giving them the
mentorship and support they need to thrive in public health work.
Pay equity is crucial to retention — organizations should be aware of the
pay disparities that exist in public health fields and actively work to correct them.
Increasing public health professionals’
cultural competency is another way of improving health outcomes for marginalized communities. As it stands, a great deal of cultural competency training takes a “one and done” approach, encouraging surface-level reflections without advocating for broader, structural change. A more effective approach would be to make cultural competency training an
ongoing process aimed at restructuring organizational culture and challenging the norms and policies that produce inequality.
By focusing on cultural competency, education and mentorship, public health practitioners have the power to change public health outcomes and better serve marginalized communities. Purdue University’s
online Master of Public Health is training a new generation of public health leaders to create solutions to the challenges social issues like discrimination present to the health of communities. With courses in epidemiology, biostatistics, health administration, social health sciences and more, this program gives students the foundational knowledge they need to excel in various public health fields.
