Out-of-shape men who work long hours more than double their risk of dying from heart disease compared to non-fit men working fewer hours, researchers report.
The study, released online in advance of publication in an upcoming print issue of the journal Heart, also found the following:
Compared with men who worked less than 40 hours per week, unfit men who worked 41 to 45 hours a week were 59% more likely to die of heart disease, although they were not more likely to die of other causes.
Compared with unfit men, those who were physically fit and worked longer hours were 45% less likely to die of heart disease and 38% less likely to die of other causes.
Being both unfit and working more than 45 hours per week more than doubled a man's risk of dying of heart disease compared with those who worked less than 40 hours per week.
