Women who work 45 hours or more each week increase their risk of diabetes

 New research has suggested that women who work 45 hours or more each week may be increasing their risk of diabetes. However, men who work the same number of hours, are not affected.
Meanwhile most prior research that has suggested a link between a long work week and an increased risk of diabetes focused on men.
Interestingly, this recent research seems to find the opposite effect in males: the longer the work week, the lower the incidence of diabetes.
For women who work 45 hours per week or more, though, their risk was considerably higher.

The authors of the new study, which was published in BMJ Open Diabetes Research and Care, looked at data from the 2003 Canadian Community Health survey, which included respondents aged 35–74.
They also looked at the Ontario Health Insurance Plan database for physician services, as well as the Canadian Institute for Health Information Discharge Abstract Database for hospital admissions.

In all, over 7,000 Canadian employees were included in the research. As well as looking at hours worked, the researchers also included other factors in their analysis, such as: sex, marital status, parenthood, ethnicity, place of birth, place of residence, long-term health conditions, lifestyle, weight, and body mass index (BMI).
The study authors also considered unique workplace factors, such as shift work and the type of job the respondents did — for instance, whether it was predominantly active or sedentary.
Overall, the risk of diabetes was "only slightly reduced" when factors such as smoking and alcohol levels were considered.
CONCLUSION
Diabetes will be reduced in women if they stop working long hours a week.
