(HealthDay News) — For women, working 45 hours or more per week is associated with increased risk of diabetes, according to a study published online in BMJ Open Diabetes Research & Care.
Mahée Gilbert-Ouimet, PhD, from the Institute for Work & Health in Toronto, and colleagues used data from respondents (aged 35 to 74 years) to the 2003 Canadian Community Health Survey to examine the correlation between long work hours and the incidence of diabetes among 7065 workers over a 12-year period in Ontario.
The researchers found that among men, long work hours did not increase the risk of developing diabetes. Among women, compared with those working between 35 and 40 hours per week, those usually working 45 hours or more per week had significantly increased risk of diabetes (hazard ratio, 1.63). After adjustment for the potentially mediating factors of smoking, leisure time physical activity, alcohol consumption, and body mass index, the effect was slightly attenuated.
“Working 45 hours or more per week was associated with an increased incidence of diabetes among women, but not men,” the authors write. “Identifying modifiable risk factors such as long work hours is of major importance to improve prevention strategies and orient policy making.”
