Shiftworking teens more prone to MS

Two population-based studies, one with 1343 cases of MS and 2900 controls and another with 5129 prevalent MS cases and 4509 controls, point to a similar added risk.

“Our analysis revealed a significant associationbetween working shifts at ayoung age and occurrence of MS,” the authors said, noting sleep loss and disruption of circadian rhythm may be to blame.

“Given the association was observed in two independent studies [this] strongly supports a true relationship between shiftwork and disease risk.”
