COVID-19

In the US, recent data shows that counties with higher proportions of black residents had more COVID-19 diagnoses and deaths, after adjusting for county-level characteristics such as age, poverty, comorbidities, and epidemic duration (Millett et al., 2020).

Millett GA, Jones AT, Benkeser D, Baral S, Mercer L, Beyrer C, Honermann B, Lankiewicz E, Mena L, Crowley JS, Sherwood J, Sullivan P - "Assessing Differential Impacts of COVID-19 on Black Communities" Ann Epidemiol (2020) doi: 10.1016/j.annepidem.2020.05.003. Epub ahead of print. PMID: 32419766; PMCID: PMC7224670.

"For example, data from the UK Office for National Statistics shows that black people in England and Wales are more than four times more likely to die from COVID-19 than are white people."

Fluoride

"Dental fluorosis ...prevalence estimates for Non-Hispanic Blacks were consistently higher than those for non-Hispanic Whites and Hispanics."

(Akinkugbe et al., 2014)

"White and Spanish-surname children had about the same prevalence of mottling while Blacks had a higher prevalence...."

"Dental fluorosis was observed in 62.5 percent White and 80.1 percent African American children."

Thyroid

Blacks have a considerable lower "normal thyroid status" and thus effects would be more pronounced among the black population. Their normal TSH level lies lower than in the white population (Long et al, 1985; Schectman et al. 1991, etc.). Since the 1980s it has been known that serum ACE activities change in proportion to thyroid hormone levels (Lee et al., 1986; Nakamura et al., 1980; Yotsumoto et al., 1983; Nakamura et al., 1982; Silverstein et al., 1983).

"Black patients had significantly more thyroid disease than Mexican-American (p less than 0.01) or white patients (p less than 0.005).”

(Long et al., 1985)

Long TJ, Felice ME, Hollingsworth DR - "Goiter in pregnant teenagers" Am J Obstet Gynecol 1985 Jul 15;152(6 Pt 1):670-4(1985)

"An unexpected finding was a significantly increased mean serum TSH in whites (2.09 + 0.91; mean + standard error of mean) when compared to blacks (1.74 + 0.10; P = 0.0185)."


(Edupuganti et al., 1997)

Edupuganti S, Svec F, Bao W, Srinivasan SR, Berenson GS - "Thyroid function in children with different lipoprotein profiles: observations in a biracial (black/white) population--the Bogalusa Heart Study" Am J Med Sci 313(2):80-4(1997)

"The mean TSH level of Blacks was 0.4 (SE .053) mU/L lower than that for Whites after age and sex adjustment, race explaining 6.5 percent of the variation in TSH levels. A validation sample yield similar results. This finding supports the possibility that differences in thyroid function and/or regulation may be associated with race."


(Schectman et al., 1991)

Schectman JM, Kallenberg GA, Hirsch RP, Shumacher RJ - "Report of an association between race and thyroid stimulating hormone level" Am J Public Health. 81(4):505-6 (1991) doi: 10.2105/ajph.81.4.505. PMID: 2003636; PMCID: PMC1405055

"African American women had significantly lower mean TSH concentrations than Caucasian, Hispanic and Chinese women."

"However, the action of thyroid hormones on angiotensin receptors is tissue-dependent. AII receptors in atrium, thoracic aortic, and liver tissues were increased in experimental hyperthyroidism in dogs (Sernia et al. 1993), similar to the findings by Marchant et al. (1993) in hyperthyroid rats, in which AII receptors were increased in the heart, liver, and kidneys but reduced in the adrenal gland."
