Women, not men who worked more than 45 hours weekly had 63% increased chance of diabetes
Women who worked long hours had a 63 per cent increased risk of developing diabetes.
But the same link was not found in men, according to the study published in the journal BMJ Open Diabetes Research and Care.
The team of authors, from Canada and Australia, examined the working hours and the incidence of diabetes among more than 7,000 workers aged 35 to 74 in Ontario, Canada.
Researchers tracked participants, who were all actively working with no history of diabetes at the start of the study, for 12 years.
Women who worked long hours – more than 45 hours a week – had a 63 per cent increased risk of developing diabetes compared with women working between 35 and 40 hours a week.
Long work hours did not increase the risk of developing diabetes among men.
They noted that previous research has indicated that long work hours can increase the tendency for unhealthy behaviours and also lead to poor mental health and sleep problems.
Meanwhile, a charity has warned the British public is “not taking diabetes seriously”.
