Nationwide — Here are some facts: Black people have been found to be more likely to die from COVID-19 infection than white people, both in the United Kingdom and the United States of America. Black people also have a higher rate of PTSD diagnosis than white people. PTSD can result in suppression of the immune system. Immunosuppression is associated with a higher risk of death from COVID-19. It is thus not unreasonable to question whether PTSD-induced immunosuppression is contributing to the elevated risk of dying from COVID-19 amongst black people.
This article proposes that PTSD-induced immunosuppression contributes to raised mortality from COVID-19. PTSD is a condition which occurs after a traumatic experience where symptoms persist of reliving the distressing event and there is hypervigilance, numbing, mood changes including negativity about the self, the world and the future. There is avoidance of people and situations that act as reminders of the event and sleep and concentration disturbance. Physical symptoms including Neurological, Respiratory and Cardiovascular symptoms also occur in PTSD.2
What is the evidence that Black people have higher rates of PTSD?
The Adult Psychiatric Morbidity Survey: Survey of Mental Health and Wellbeing, England, 2014 found doubling of the rate of PTSD amongst black adults at 8.3 per compared to white adults at 4.2 though assumed that the differences could not be relied on because of the small sizes involved.3
One study found that when PTSD affects US race/ethnic minorities, it is usually untreated and likely to become chronic and persistent and suggested that the large disparities in treatment indicate a need for investment in accessible and culturally sensitive treatment options.4 A separate two year follow up study found that African Americans with PTSD experience high number of traumas and most do not receive treatment.5
Findings from large-scale national studies suggest African Americans have a 9.1% prevalence rate for PTSD.6 This suggests that almost one in ten Black people becomes traumatized. This is an underestimate due to known under-diagnosis of PTSD in black people.7 Studies of racial discrimination and race-related stress have shown that when an individual reports psychological distress from racism, trauma was often not considered.8
Why would Black people be at increased risk of PTSD?
In addition to traumatic experiences that a person of any race or ethnicity might face, race-specific traumas include micro-aggressions and the erosion of a fundamental requirement for human beings – a sense of belonging. A striking example of that undermining of belonging was witnessed by the Windrush generation in the UK. Black people face challenges to a sense of belonging to desirable social, housing, occupational groups and on a wider scale there are challenges to the black person’s right to belong in a country such as the UK, a crude example being the ‘go back to where you came from’ statement. A sense of belonging is an intrinsic human need. The psychologist Maslow’s hierarchy of human needs defined self-actualization and self-esteem as requiring the secure foundations created by a sense of belonging.
Another often overlooked contributory factor to the large prevalence of traumas affecting Black people is Intergenerational transmission of trauma. Parent-child attachment patterns are known to replicate through generations within families. Going back to slavery and post-slavery eras, forced black familial disruption was part of the mechanism that enabled forced labour and enrichment of slave owners and others and this involved brutal disregard for the integrity of the black family unit by white oppressors. Yet another overlooked factor is vicarious trauma and witnessing shootings of unarmed black people can give rise to a sense of threat to the black viewer’s sense of their own safety.
What is the evidence that PTSD suppresses the immune system?
A study of 1,550 male workers with a previous history of PTSD concluded that PTSD produces immunosuppression and has long-term implications for health.9 This finding is now widely accepted amongst mental health professionals and a questionnaire commonly used as a tool to diagnose PTSD is the IES-r.10 A cut-off point of 37 and above in the IES-r is commonly accepted by mental health workers as associated with immunosuppression.
Treatment of PTSD
PTSD in Black people is treatable with a growing number of psychotherapies including prolonged exposure therapy, EMDR, cognitive processing therapy, somatic experiencing, if delivered by psychotherapists with training and knowledge of diversity matters. Medication is sometimes but not always required.
Conclusion
There now exists evidence for higher death rates of Black people from COVID-19 compared to White people as well as evidence that Black people have a higher rate of PTSD diagnosis than White people and furthermore that PTSD is associated with immunosuppression and we know that immunosuppression is associated with a higher risk of death from COVID-19. The proposed association described here between PTSD-induced immunosuppression and increased risk of death from COVID-19 needs to be explored further and in addition, high PTSD rates in black people need to be recognised and treated as both a mental and physical health priority.
