Irregular schedules raise the risk of type 2 diabetes.

Women who worked at least three night shifts per month (in addition to days and evenings in the same month) for 20 or more years experienced a 58% increase in the risk of type 2 diabetes compared with those who did not rotate shifts. Those who had less than 10 years of rotating shifit work experienced a 5% increase, while the risk rose to 40% among those with 10-19 years. This data comes from the Nurses Health Study I and II and was adjusted for weight gain and smoking.
