Study shows how night shift work can raise risk of diabetes, obesity

SPOKANE — Just a few days on a night shift schedule throws off protein rhythms related to blood glucose regulation, energy metabolism and inflammation, processes that can influence the development of chronic metabolic conditions. The finding, from a study led by scientists at Washington State University and the Pacific Northwest National Laboratory, provides new clues as to why night shift workers are more prone to diabetes, obesity and other metabolic disorders. “There are processes tied to the master biological clock in our brain that are saying that day is day and night is night and other processes that follow rhythms set elsewhere in the body that say night is day and day is night,” said senior study author Hans Van Dongen, a professor in the WSU Elson S. Floyd College of Medicine. “When internal rhythms are dysregulated, you have this enduring stress in your system that we believe has long-term health consequences.”
