Working Day and Night May Lead to Diabetes

Study finds spending more than 55 hours on the job might raise your risk

ou know all work and no play makes Johnny a dull boy, but what you may not know is that working long hours may also make Johnny more likely to develop diabetes—if he has a blue-collar job, that is.

Research from a new study examined data from prior studies involving more than 222,000 men and women in the United States, Europe, Japan and Australia and found that people who worked more than 55 hours a week at manual labor jobs were 30 percent more likely to develop diabetes than those who worked 35 to 40 hours a week.

This increased risk was the same even after researchers accounted for diabetes risk factors such as smoking, physical inactivity, age, gender and obesity. Researchers also excluded shift work, which has been shown to raise the risk of obesity and diabetes.

Although the study found an association between long work weeks and diabetes, it didn’t establish a cause-and-effect relationship. Researchers suggest that people who work long hours have little time for healthy behaviors, including exercise and enough sleep, which could lead to the increased risk.

“Although working long hours is unlikely to increase diabetes risk in everyone,” said Mika Kivimaki, professor of epidemiology at University College London in England, in a release, “health professionals should be aware that it is associated with a significantly increased risk in people doing low socioeconomic status jobs.”
