Geoffrey Calvert, MD, MPH, FACP, shares insights from a study of a nationally representative sample of the US working population to examine the role of shift work in sleep quality, sleep-related activities of daily living, and insomnia on a CDC blog.

From our study of this large, nationally representative sample, we concluded that sleep-related problems were common among workers, especially among night-shift workers who had the highest risks for sleep problems. Moreover, these risks among night-shift workers persisted even after we adjusted for potentially confounding factors, such as long working hours, socio-demographic characteristics, and health/lifestyle/work factors.
