People continue to ask me about health issues and why Black Americans’ health is inferior to every other racial or ethnic group. My podcast Better Black Health covers many of these important topics. The environmental dynamics of being Black drives up our blood pressure, increases our risk for cancer, and makes us struggle with our weight and diabetes. The Better Black Health podcast is also on Spreaker and Spotify to allow easy access to this vital information.
Why do African Americans have a greater cancer risk with smoking . . . and why do so many smoke menthol cigarettes? There is a potential genetic reason behind this huge disparity. And stopping smoking was much harder when there was a household partner or family member who still smoked.
Why do Blacks distrust healthcare providers (doctors, NPs, etc.) at such a high rate? How does our history with medical providers drive this dysfunctional relationship?
The first episode looks at a curious case of high blood pressure and the potential causes including alcohol, sleep apnea, and heart disease.
A follow up episode looks at the vitamin needs of African Americans.
There is definitely a science to sleep and why sounds can both improve or interrupt a good night’s sleep. The internet is filled with people who report greatly improved sleep with sound producing devices, long-playing internet videos, and other media. The sound of ocean waves, constant rain, or even a partners’ breathing has been reported to promote a more restful sleep. Curiously, when sleep experts at the University of Pennsylvania Perelman School of Medicine recently pulled together research in the field, they found “the quality of evidence for continuous noise improving sleep was very low.” Their disclaimer added that more research is needed in higher numbers to either fully discredit or completely support the use of “noise” as a clinically beneficial sleep aid.
What are the potential benefits?
There are components of sleep that improve or detract from its quality. By minimizing the onset, and the interruptions in sleep, it is presumed that the duration of the restorative components (REM sleep and non-REM) will improve. Deep sleep, which is the most restorative and a component of non-REM sleep, shortens with age and its reduction has been liked to poor health including obesity, diabetes, hypertension, heart disease, and more. By improving overall sleep duration by reducing interruptions and decreasing the time it takes to go to sleep, it is hoped that a better quality of life ensues.
What type of noise is best to listen to on a sound machine? White noise, pink noise, or any other types.
There is a science behind the various noises and why they may help sleep. White noise is a balanced frequency of sounds that has a higher overall pitch. Because higher pitched sounds are more easily heard by the human ear, a balance of sounds with give an overall higher pitch. Pink noise is proportionately decreased as the pitches increase in an effort to better “balance” what is actually heard. Pink noise therefore has a lower, and some say, more soothing, tone. To takes this concept even further (and more soothing), Brown noise (Brownian noise) decreased the frequency even lower than pink noise. There is no scientifically reported evidence that one noise is better than the others . . . just personal preference.
How does the experience of listening to a sound machine differ from sleeping in silence?
The difference between silence and consistent invariable noise is not as great as some would think. The issues with sleeping in silence is the potential interruptions by sound. The “noises” I have described work to potentially drown out the sound variabilities in life. True silence has no interruptions and is consistent. These various noises work to make urban (or even rural) existence less variable in sound and thus more conducive to uninterrupted sleep.
As descendants from Africa, African Americans were genetically conditioned to best survive in a hot, sunny, mineral rich land. The continent of Africa is known for its fertile land and renowned as the “richest continent in the world” in terms of natural resources. The days are sunny and generally consistent in length throughout the year. Living in a mineral rich land, your body adjusts its absorption of vitamins and minerals according to it’s exposure in the environment. In Africans, their absorption is blunted because the environment is so fertile with sun, nutrients and minerals. When relocated to North America, with its variable daylight, urban dynamics, and processed food and water, African Americans are now displaced from the environment that their system was best designed to thrive.
Low Vitamin D and Increased Health Problems
With vitamin D generally coming from the sun, the shift from Africa to North America was dramatic . . . and so was the drop in vitamin D in Black Americans. Low vitamin D has been linked to more severe COVID illnesses, increased diabetes (type 2), increased prostate cancer, increased colon cancer, worsened asthma, and more. The graph below from a study done at the University of California at Berkeley shows significantly higher vitamin D levels in both men and women in Africa and Jamaica that are consistent with those of white Americans . . . whereas the levels in Chicago Blacks were much lower.
Blacks in America need vitamin D supplementation to offset the significantly decreased vitamin D we get from the diminished sun in North American cities. It is proposed that the added vitamin D will help to offset some of the worsened diseases we see in African Americans.
Africa has also been known to have high zinc reserves. In fact in some mining areas in African, the mineral content of “heavy metals” in the water was too high. From a biological perspective, the people living in these high mineral content areas needed to develop a way of decreasing their absorption of too much minerals, including zinc. In a study done looking at prostate cancer tissue in Black Americans versus whites, researchers found significant fewer zinc absorption (“transport”) channels in the prostates with the more aggressive cancer, and this decreased zinc transport occurred much more often in African Americans than whites. Overall, zinc has the highest concentration in the body in the prostate, and scientists report that the high zinc in the prostate acts to suppress tumor formation. The graph below shows the higher prostate cancer incidence in green as well as the higher mortality (red) by race/ethnicity.
African American men should take zinc daily.
Vitamin C has long been known to benefit a number of health conditions including boosting immunity (your ability to fight infections), slowing atherosclerosis (hardening of the arteries), decreasing gout attacks through lowering uric acid levels, as well as improving lead clearance from the body. Taking vitamin C on a daily basis either in the form of high vitamin C foods or supplements is highly recommended.
Vitamin K promotes blood clotting. While biologists have insisted that vitamin K doesn’t cause “too much clotting” there have been no studies in African Americans to confirm this. Given the lack of vitamin K deficiency in the US, there is no reason for an African American to take added vitamin K.
MD Newsline just featured Sequence Multivitamins on their website as a game-changing approach to nutrition in the Black community.
Sequence Multivitamins for African Americans have increased vitamin D, vitamin C, magnesium, potassium, and zinc to compensate for the migration from Africa to North America and the dramatic adjustments that many of our bodies are still making! And it leaves out vitamin K to potentially avoid an increased risk for blood clots.
While cleaning a closet I found this article from the Plain Dealer about my 6th grade teacher Elizabeth Clarke. Mrs. Clarke was legendary in many ways. As the teacher of more than a generation of successful African Americans in Cleveland, her success with students was no accident. As a teacher at Miles Standish Elementary School in the Glenville neighborhood where I grew up, she taught many of my family and friends including two of my brothers and my wife. She also has taught a who’s who of African American success stories in Cleveland including TV personality Leon Bibb, prominent attorney Inajo Davis Chappell, Judge Ray Headen, former Mayor Mike White, and many others.
Mrs. Clarke demanded success and expected it of all of her students. She was incredibly strict and ruled by intimidation and ridicule . . . which in my case was the perfect motivation. We were told we were better than the other students in the school and we needed to act like it, we were in “Mrs. Clarke’s class.” Even within the class, she had her favorite students and everyone knew their status. I was one of her favorites as was Inajo, Ray, Miles Roach and others. My brothers and others were not so lucky.
The basics plus more . . .
Mrs. Clarke insisted we learn the educational basics of elementary school as fast as we could. Simply learning the multiplication tables was unacceptable, we needed to learn and recite them in lightning speed. Stuttering, or breathing for that matter, meant we had to see her exasperation and start again from the beginning. I can still recount those tables in my head when needed.
We also had to learn to diagram sentences which apparently had been a long abandoned approach to grammar, but not in Mrs. Clarke’s class. We all strove for her complimentary comments on our homework: “Very Excellently Done!” I’ve embedded a video of diagramming sentences for those of you unfamiliar.
“What does Africa mean to me?”
Most important in her class was to learn a deep appreciation for the continent of Africa. As the PD article describes, she won a paid excursion to Africa as a Master Teacher and continued to go whenever she could. Because of her stern nature, she didn’t smile much, but when she did, Africa was likely the topic of discussion. Annually, she would put together a student performance that educated students at other schools about the rich culture, values, and contributions of our African heritage. Like everything else, that performance had to be perfect every time . . .and it was. We were also the children of Africa and needed to represent that continent impeccably.
47 years later, here I am writing about a truly masterful teacher who made an indelible mark in the lives of many. Her approaches to teaching would surely not be allowed today. Her deviation from the standard 6th grade curriculum, blatantly “having favorite students”, discounting other students as not as good, and using fear as a primary motivation to learn, would all draw stern criticism from today’s educational leaders.
But the fact remains that Elizabeth Clarke, the Master Teacher, set a path for our success that was deliberate and incredibly impactful. She laid the foundations for learning and the expectation for excellence that many of us carry to this day. There may have been other students that needed a different method for learning, or a more loving approach, but that was never her intention. She unapologetically demanded superiority of her students and accepted nothing less.
For my life, and the lives of a few others, Mrs. Clarke was exactly what we needed to build our self-confidence, to gain appreciation for our heritage, and to carry and exemplify that pride and expectation of more, to the next generation.
For that, we say “Very excellently done, Mrs. Clarke.”
Hospitals across this nation use protocols and algorithms aimed at improving outcomes in their patients, but because of nuanced differences in the care of African Americans, those protocols have now been shown to negatively impact African American healthcare. A recent article in Science, “Dissecting racial bias in an algorithm used to manage the health of populations” reviewed outcomes data and found that “Black patients assigned the same level of risk by the algorithm are sicker than White patients.” Essentially the computer “assumes” that African Americans are healthier than they are because of their decreased use of certain medical care services.
The predictive model uses, among other things, cost of care as a marker for health. Because of bias in providers, less interventions are ordered and completed, less referrals to specialty providers, and less orders for a number of counseling opportunities. African American patients, across the population have less successful follow up with physicians, fewer prescriptions filled and refilled, and more missed appointments. These combine to produce an outcome that mathematically would suggest better health, but instead bias on both the patient and providers’ part is driving worse outcomes.
Large hospital and hospital systems spend a significant amount of money trying to save money. There are a number of “risk-prediction tools” that are used to target “high risk” patients that would get more attention, added studies, longer stays, increased follow up, and more. Knowing the significant health disparities impacting African Americans, one would assume that added attention would improve these rock-bottom outcomes, but the “predictive model” does the exact opposite and suggests less interventions.
The study also found a difference in healthcare-related spending with African Americans having “fewer inpatient surgical and outpatient specialist costs, and more costs related to emergency visits and dialysis.”
The take-home message is bias on almost everyone’s part (provider, social worker, discharge planner, patient, hospital, etc.) negatively impacts African American health and healthcare outcomes. Systems and algorithms designed to improve outcomes and save money are actually driving up cost and decreasing quality outcomes in African Americans. Bias-driven outcomes can easily be tracked, considered and corrected.
In addition to bias, there are other African American healthcare differences that impact hypertension, diabetes, stroke, diet counselingand more. These differences, by and large, are also being ignored by hospital systems, medical schools and providers.
Early in Dr. Hall’s public health career, he was chosen to chair the Cleveland Clean Indoor Air Committee under Mayor Jane Campbell. At the time, the issue was very controversial, but as time passed, people have accepted clean indoor air as a way of life. And the smoking rate has drooped from 42% in the 1960’s to an all-time low of 15% currently with more planning to quit.
