World Mental Health Day: Closing the gap of disparities in mental health

Published Oct 10, 2021 • By Courtney Johnson

For World Mental Health Day, a day held annually on October 10th to raise awareness for mental health issues across the world and mobilize support, we wanted to shine a light on an important topic: disparities in mental health. 

Research in recent years has uncovered disparities between different populations in terms of risk, prevalence, presentation, and therefore care of mental health conditions.  

What are these disparities in mental health? Which populations are affected? What can we do to close the gap and ensure mental health care for all? 

We discuss it all below!

World Mental Health Day: Closing the gap of disparities in mental health

Mental health is a topic that has gained more attention in recent years. The national conversation about mental health is often activated by a negative crisis, such as a terrorist incident, the death of a public figure, or more recently, a global pandemic. However, the mental health challenge that many people face is a much larger issue and is often experienced out of the public eye and concern. 

The prevalence of mental health issues is on the rise 

In 2016, it was estimated that around 1.1 billion people were living with a mental illness worldwide. According to the National Alliance on Mental Illness (NAMI)1 in 5 adults in the United States lives with a mental illness (51.5 million in 2019).  

Globally in 2018, the World Health Organization found that the most prevalent mental illness diagnoses were depression, affecting around 300 million people; bipolar disorder, with around 60 million people diagnosed; schizophrenia and other psychoses, affecting approximately 23 million people across the globe; and dementia, with around 50 million people living with the disorder.   

Researchers in the US have additionally reported that mental health conditions, including depression, are the third largest cause of hospitalization for adults aged 18-44

While these numbers are concerning, a further issue that receives insufficient attention is mental health disparities. Within this group of already marginalized individuals, there are subsets of people who face even greater challenges

What are mental health disparities? 

The Institute of Medicine (IOM) defines a disparity as a “difference in the quality of health care not due to differences in health care needs or patient preferences.” These differences can have their origins in inequalities in access to quality healthcare providersvariations in insurance coverage, or discrimination by healthcare professionals during clinical evaluations. 

Other common barriers to mental health care include: 

  • Social stigma about mental illness 
  • Previous negative experience in medical or mental healthcare 
  • Limited mental health literacy, or knowledge and beliefs about mental health conditions that aid their recognition, management, or prevention 
  • Language barriers 
  • Sociohistorical experiences 
  • Desire for self-reliance or self-support 
  • Lack of financial resources 
  • Proximity to mental health services 
  • Lack of culturally competent healthcare providers or services 

Many of these barriers, notably limited English language skills, insufficient health knowledge, lack of insurance, and geographic inaccessibility are more common among immigrantsminority groups, people of lower socioeconomic status, individuals located in rural areas; these groups are therefore more likely to face mental health disparities

Which populations are more likely to experience mental health disparities? 


Although on average 1 in 8 men, versus 1 in 5 women, are facing a form of mental illness, men are actually underdiagnosed. They are statistically less likely to be diagnosed with common mental illnesses such as depression, anxiety, obsessive-compulsive disorders, and phobia

The National Institute of Mental Health (NIMH) has found that one of the difficulties in treating men is a lack of knowledge or understanding among mental health professionals about the common indications and symptoms of mental illness in men, which can differ from those in women.  

Additionally, many men are reluctant to seek help for mental health issues due to certain biological, psychological, and even more significant cultural reasons, such as social stigma. Men are often socialized with particular “masculine” ideals that discourage them from getting treatment and believe that if experienced, mental illness should be handled on one’s own. The notion that depression is a self-limiting illness, that using drugs is an efficient method to cope with it, and that depression is caused by personal weakness are all factors that encourage men to manage depression alone. 

Young adults 

According to NIMH, 75% of all lifetime cases of mental health disorders begin before age 24. However, it is young adults who have the highest prevalence of mental illness and the lowest rate of mental health service usage. For example, in 2016, 22% of young people were diagnosed with a mental illness, but only 35% of those individuals sought help

Both suicide and substance abuse are also significant concerns for this population: the Substance Abuse and Mental Health Services Administration (SAMHSA) reports that young adults had the highest rates of suicidal ideation, planning, and attempts across all adult age groups in 2016 and around 15.5% of young adults (5.3 million people) sought treatment for substance abuse

Black, Indigenous, and People of Color (BIPOC) 

Statistical studies have found that in general, most racial, or ethnic minority groups in the US have similar rates of mental illness than whites. However, the consequences of mental health disorders on BIPOC individuals may be much more profound. 

Black, indigenous and people of color are disproportionately faced with challenges linked to mental illness, such as violencepoverty, and homelessness, as well as significant impediments to accessing quality mental health care. Research indicates that in comparison to white people, BIPOC are: 

  • Less likely to seek out mental health services 
  • Less likely to have access to services 
  • Less likely to receive necessary care 
  • More likely to receive substandard care 
  • More likely to end mental health services or care early

BIPOC also have a disproportionate representation in the criminal justice system, a system that conflates race and criminality. Statistics have shown that over 50% of incarcerated individuals meet criteria for a mental health disorder, which suggests that instead of receiving treatment for mental health conditions, BIPOC are imprisoned as a result of their symptoms. 

Additionally, a majority of mental healthcare providers in the US are white – the American Psychological Association indicates that around 86% of its member psychologists are white, and less than 2% are Black. Research has shown that healthcare provider bias and stereotyping are important factors in mental health disparities because they contribute to mis- or underdiagnosis of mental illness

Other factors that contribute to barriers to mental health treatment for BIPOC include social stigma of mental illness among ethnic or racial minority communities, language differences between the patient and provider, and cultural presentation of illness symptoms. 


In February 2021, a Gallup poll found that 5.6% of US adults identify as part of the LGBTQIA+ community. A research article published in the BMC Psychiatry Journal in 2016 that pooled data from several studies in the UK determined that LGBT individuals are more than twice as likely as heterosexual people to experience mental illness in their lifetime. Furthermore, the prevalence of depressionanxiety, and substance abuse among LGBT individuals has been found to be 2.5 times greater than that of cisgender heterosexuals. 

LGBTQIA-identifying individuals encounter a variety of problems and impediments to mental health care access, including a scarcity of professionals competent in LGBT health issues, a lack of health insurance coverage and personal financial resources, and inadequate transportation to LGBT-specific health services.  

Despite these obstacles, LGBT people used mental health services at greater rates than heterosexual men and women in 2016. Yet, many LGBTQIA+ people have reported feeling uncomfortable in medical settings as a result of prior discrimination based on sexual orientation or identity. As a result, many patients may skip or postpone necessary medical or mental health procedures and services

What can we do to close the gap in mental health disparities? 

It is clear that the mental health system is flawed and that efforts need to be made to bridge the gap to ensure that mental healthcare is accessible to all. 

But what can we do on an individual level to help make positive change? 

Reduce mental health stigma 

Stigma can cause us to feel ashamed for things that are out of our control, like our mental health, and can keep us from getting the help we need. 

It can be hard, but a key way to end stigma against mental health is to talk about it. Sharing our experiences with mental health – both the good and the bad – helps to educate others who may not be aware and to break down outdated societal prejudice. 

Lobby your legislators to improve accessibility 

To encourage change at a larger scale, we can write, call, or talk to legislators – both local and federal. It is important to call on those who represent us to support efforts to improve access (both financial and geographic) to and the quality of mental health services on a community and national scale.

Yes.  I do not play around with my health.  It is alarming when you hear the the statistics of  Covid-19 deaths.  Having the vaccine is a life saver.  Why take the risk?
