Systemic inequities in the U.S. healthcare system have impeded many people’s ability to obtain essential medical care. Factors such as race, sexual identity, occupation, housing status, and education level can negatively impact the quality of care people receive. The government and medical organizations often perpetuate disparities due to historical and systemic discrimination. Eliminating inequities in health care requires the removal of various barriers. According to the U.S. Department of Health and Human Services, “Achieving health equity involves examining the existence of and reduction of inequities in health, healthcare access, and use of quality health services.”

Those interested in promoting health equity need the right preparation. Tulane University’s Online Master of Public Health fosters the skills students need to understand what health equity is and effect meaningful change in the realm of public health.

What Is Health Equity?

Health equity means that every individual has an equal opportunity to live the healthiest life possible. People’s race, economic circumstances, sexual identity, or gender should not affect their access to such basics as healthy food or proper medical care, nor should anyone’s geographic region determine the level of health education available to them. However, today these factors influence our nation’s disease rates, life spans, disabilities, and mortality rates.

According to the National Vital Statistics System, life expectancy can vary by up to seven years between racial and ethnic populations. An unequal distribution of resources contributes to many such alarming disparities. While health differences will always exist, the American Public Health Association (APHA) explains that we can avoid those “linked with social, economic, and/or environmental disadvantage.”

Why Is Health Equity Important?

Health equity matters because imbalances in health access lead to differences in life expectancy and quality of life; health disparities also weigh heavily on the economy. Inequities in health access cost the U.S. billions of dollars in lost productivity and excess medical expenses. Failing to address the urgent need to establish health equity hurts everyone.

The barriers to achieving health equity are great but not insurmountable. Public health professionals stand on the front lines of the fight. With ingenuity and tenacity, they can help eradicate unjust and unnecessary disparities. APHA describes the importance of health equity and outlines six strategies that should guide the work of public health professionals:

  1. Explicitly identify communities who suffer health disparities.
  2. Confront racial biases in policies and behaviors with training and education.
  3. Address how housing, employment, transportation, and other determinants affect health equity.
  4. Implement health equity goals into organizations while also ensuring internal organizational practices do not contribute to health disparities.
  5. Engage affected communities to actively participate in solving the problems they face.
  6. Assess the impact of initiatives meant to reduce health inequities.

Barriers Preventing Access to Health Care

To answer the question, What is health equity? and develop a comprehensive understanding of how to achieve it, we must closely examine some factors that create health disparities and prevent people from accessing care.


What we eat and the quality of our food directly impact both our physical and mental development. Poor nutrition can negatively affect growth and prevent us from reaching our full potential. Poor diets result in weakened immune systems, increasing susceptibility to communicable diseases, and poor diets contribute to noncommunicable diseases such as diabetes, stroke, and even some cancers. However, a proper diet can potentially stave off these unfortunate health outcomes.

What happens when a community lacks access to fresh and healthy food? According to the Centers for Disease Control and Prevention (CDC) poor access to nutritious foods leads to unhealthy diets. Today, many rural, minority, and low-income communities in the U.S. are known as food deserts. Food deserts have very few grocery stores that provide fresh fruits, vegetables, and other whole foods. The stores available in food deserts sell mostly high-fat, high-sugar, processed foods. People who live in food deserts will inevitably find it more difficult to eat a healthy diet, which accounts for their higher rates of negative health outcomes.

For instance, living in economically disadvantaged neighborhoods has been associated with increased risk of cardiovascular problems. The study “Change in Neighborhood Characteristics and Change in Coronary Artery Calcium” suggests food deserts might be to blame. According to the research, those living more than a mile from fresh food sources develop coronary calcium build up, a leading risk factor for heart disease, faster than those living outside of food deserts.

According to the United States Department of Agriculture (USDA), up to 18 percent of the population lives in food deserts. Public health professionals work to combat these figures by advocating for programs, such as the federal government’s Healthy Food Financing Initiative, that support the opening of fresh food sources like grocery stores and farmers markets within food deserts.

However, solving the problem of poor nutrition in these communities requires more than introducing grocery stores and farmers markets into food deserts. True access to good nutrition requires increasing awareness about healthy food choices. Public health advocates play a key role in providing the information communities need to change food purchasing behavior and assume healthier habits. In addition, public health advocates can promote the adoption of government programs that defray the cost of healthy foods for low-income communities so they can afford to buy them.

Variations in life expectancy by neighborhood

Data and research from the CDC indicate that people who live in certain geographic areas — identified down to the zip code level — can have lower life expectancies than those of their immediate neighbors. Public health professionals target these geographic areas in order to address the factors responsible for such gaps. People living in certain geographic areas and neighborhoods can face a variety of issues that impact their health.

  • Transportation
    Those who cannot afford the expense of a car will likely need reliable and affordable public transportation to access meaningful employment, child and health care, as well as other services. Individuals living in areas where such transportation does not exist often find themselves isolated from opportunities and cut off from meeting basic needs associated with health care and nutrition.
  • Crime
    Crime affects low-income neighborhoods at higher rates, and exposure to violence produces many health and behavioral issues. Children who live with the threat of violence experience increased levels of depression and anxiety and exhibit increased aggression. As adults, they are at a greater risk for alcohol and drug abuse as well as risky sexual behavior.
  • Poverty
    Those living in poverty face greater obstacles to receiving medical care, including primary and specialty care. When they do receive care, they are less likely to be treated with newer drugs or more advanced technologies. Their higher stress environments also make them more susceptible to behavioral risk factors such as smoking, drinking, and obesity.
  • Environmental hazards
    Living in environments with greater exposure to pollutants can adversely affect health and cause disease. Low-income individuals and minority communities experience greater exposure to air pollution and lead-based paint. They are also more likely to live near toxic waste facilities and landfills and have reduced access to clean drinking water.

Cultural humility

Our communities and cities are diverse, and all individuals face unique roadblocks that can obstruct their ability to live healthy lives. When it comes to sexual orientation, socioeconomic background, or race, religion, and ethnicity, living a healthy life can mean something different to each community. Public health leaders must understand the needs of specific communities to ensure all individuals have an equal opportunity.

Healthcare providers and institutions must operate with sensitivity to social and cultural differences if they want to create health equity. People from different backgrounds may have perspectives about health unknown to their providers, or they may have different expectations that can affect how well they adhere to medical advice. According to research discussed in the article “Evidence on Patient-Doctor Communication” published in the journal Cancer Prevention & Control, 22 studies indicate that communication between patients and providers correlates with health outcomes.

Achieving cultural humility requires clinicians to examine their biases, attitudes, and beliefs, all of which can potentially contribute to delivering disparate care. Unconscious bias can also influence how healthcare providers diagnose and treat their patients. Numerous studies testing bias have demonstrated how preconceived notions about different groups have resulted in different treatment regimens and misdiagnoses, among other inconsistencies.

One such study, called “Do Gender and Race Affect Decisions About Pain Management?” published in The Journal of General Internal Medicine, found that doctors prescribe African American men less pain medication than their white counterparts for the same conditions. Another study, called “The Effect of Race and Sex on Physicians' Recommendations for Cardiac Catheterization” published in The New England Journal of Medicine, found doctors had different patterns when referring patients for cardiac catheterization based on race and gender. Doctors referred fewer African American women for the procedure even though they presented with the same symptoms. Clearly, confronting health disparities requires addressing cultural competence so such discrepancies can be eliminated.

Role of Public Health Professionals in Ensuring Health Equity

Public health advocates ensure health equity by working within local agencies and programs, tackling the challenges of advancing health in a variety of ways. Organizations such as the Louisiana Public Health Institute utilize a multitiered approach to addressing health disparities through research, communications, partnership building, and the implementation of programs. By using social media and marketing, they work to inspire collective action that improves community health. They collect and organize data to help government agencies, community-based organizations, and others make evidence-based decisions and policies. They also design health initiatives for the local, state, and national levels.

The Louisiana Public Health Institute works across different sectors in order to address the layers of issues that play into health disparities. They collaborate with urban housing planners, social service providers, regional and national partners, local residents, and others to improve behavioral and family health and to ensure better and more accessible health care to communities overall.
