Stress of Discrimination Can Harm Mental Health
Discrimination can lead to economic inequalities as well as inequities in health outcomes. In a new study, UCLA researchers have shown how stress from discrimination can influence mental well-being.
“We now have decades of research showing that when people are chronically treated differently, unfairly or badly, it can have effects ranging from low self-esteem to a higher risk for developing stress-related disorders such as anxiety and depression,” said Dr. Vickie Mays, a UCLA Fielding School of Public Health professor.
Mays has done research in collaboration with Dr. Susan Cochran, a professor in the department of epidemiology at UCLA, that has helped document those links.
Alteration of a person’s mental health is a serious action that can influence a variety of detrimental consequences. Researchers explain that when the mental health of one person is affected, it can produce a domino effect extending beyond that individual.
“We know that when people have a psychiatric disorder, it’s not good for any of us,” Mays said. “For example, it can affect parenting — a depressed mom might not be able to interact with her child in a way that best promotes that child’s development, leaving the child more vulnerable to certain behavioral disorders. In that sense, we all suffer from the effects of discrimination.”
This finding was demonstrated in an earlier study by Dr. Gilbert Gee, a professor in the Fielding school’s Department of Community Health Sciences. His study assessed the extent to which Asian-Americans who reported being the victims of discrimination were more vulnerable to developing clinically diagnosable mental disorders.
“Much of the research has focused on symptoms of sadness and anxiety resulting from the mistreatment, and that’s very important, but we wanted to look at clinical outcomes,” Gee says.
Even after taking into account other potential causes of stress, Gee found a clear relationship between discrimination and increased risk of mental disorders.
Since that study, other researchers have reported similar results in African-American and Latino populations, as well as in other populations around the world, Gee said. He also found in a 2014 study of Latinas/os, that discrimination was significantly associated with increased risk of alcohol abuse among women and increased risk of drug abuse among men.
In 2015, Gee and colleagues performed an analysis drawing from approximately 300 studies conducted around the world over the last three decades. This meta-analysis concluded that self-reported racial discrimination is consistently related to poor mental health.
Discrimination is incredibly complex and experienced in so many different ways that it can be difficult to pinpoint the process by which it undermines mental health, researchers say.
“There are so many different routes, some of them direct and some of them indirect,” Gee said. He points out that while a hate crime occurring in a community is certain to affect the mental health status of the victim and the victim’s family, it can also have a spillover effect for acquaintances and non-acquaintances in the community.
Poor treatment based on race, ethnicity, sexual orientation and other factors can occur through interpersonal insults as well as through more insidious routes.
“If you don’t get a job and you’re left to wonder whether it had to do with your race or gender, that can have an impact on your mental health,” Gee said.
Emerging research using neuroimaging tools is helping to isolate the brain mechanisms at play in these scenarios.
A study led by one of Gee’s postdoctoral fellows recorded South Asian women talking about their experiences of being treated poorly. The researchers then had the women listen to the recordings while their brains were scanned using functional magnetic resonance imaging. The parts of the brain that responded as the women listened were the same as those that regulate emotions and stress.
More recently, Mays has collaborated on a study showing that experiencing significant amounts of discrimination over time can lead to changes in the way the brain processes information, disrupting, for example, the regions involved in planning and decision-making.
“When we’ve had these experiences and anticipate that other incidents might lead us to be discriminated against, it can interfere with our ability to cognitively function at our best,” Mays said.
In an address at the American Psychological Association’s annual meeting last year, Mays argued that, even as research continues to unravel the mental health effects of discrimination, more action should be taken to apply what is already known.
“Public health can do a great deal to improve the mental health status, as well as the physical health, of people who are mistreated,” Mays said. “There is science that can help us to design effective interventions.”
Mays calls for a better coordinated public health effort to better integrate what is known about the outcomes of discrimination into health care profiles.
“We screen for mental health disorders when we are putting together an individual’s electronic health record, but maybe we also need to ask about their experiences with discrimination, which would identify people at risk who could benefit from prevention efforts,” Mays said.
“And among patients who experience high levels of discrimination, we need to be concerned with the potential for distrust of the health care provider. It could be that if we want better health care outcomes, we should allow these patients to know more about the provider they are selecting to ensure it’s someone they are comfortable with.”
Gee believes public health can also do more to help shape future legislation that would both reduce discrimination and improve the mental health of its historic targets. “Policies that promote human rights can not only buttress the foundations of a civil society,” Gee said, “but they can also make for a healthier one.”
