Qattea, I., Farghaly, M. A., Elgendy, M., Mohamed, M. A., & Aly, H. (2022).
Neonatal hyperbilirubinemia and bilirubin neurotoxicity in hospitalized
neonates: analysis of the US Database. *Pediatric Research*, *91*(7),
1662-1668.

This study found again a lower population rate of jaundice in black infants
in the US --- but what is the physiologic reason? (It is disheartening to
read the conclusion however

" Black neonates were less likely to be diagnosed with hyperbilirubinemia
than White neonates (aOR = 0.77, 95% confidence interval (CI): 0.77–0.78, p
< 0.001) and more likely to develop bilirubin neurotoxicity than White
neonates (aOR = 3.0.5, 95% CI: 2.13–4.36, p < 0.001). Bilirubin
neurotoxicity rate in the overall population was 2.4 per 100,000 live
births. CONCLUSIONS: Bilirubin neurotoxicity has significantly decreased in
term infants and did not change in preterm infants. Despite the less
diagnosis of hyperbilirubinemia in Black newborns, they are
disproportionately at increased risk of developing bilirubin neurotoxicity
when compared to White newborns.  "

But - why??

Thank you  colleagues - I didn't know who else to ask!
