An Oldie, but a Goodie

I know this study, Postnatal Development of Circadian Rhythm in Serum Cortisol Levels in Children, was originally published way back in 1983 in Pediatric magazine, but some research is timeless. The authors found that “a distinct circadian rhythm with an amplitude comparable to that of an adult emerged at approximately 6 months of age,” which of course immediately makes me wonder about the babies of shift workers, and what the effects would be of disrupted circadian development, but in the over 30 years since its original publication, I don’t think anyone has studied that aspect. Please comment if you feel my statement is in error!
