Adults who put in long hours at the office may face increased risk for stroke, according to an international meta-analysis published in the Lancet.
Researchers pooled data from 25 prospective cohort studies that comprised over 600,000 adults who were free of coronary heart disease (CHD) and nearly 530,000 who were free of stroke at baseline. During roughly 7–8 years’ follow-up, some 4800 incident CHD events and 1700 strokes occurred.
In analyses adjusted for age, sex, and socioeconomic status, working 55 or more hours per week was associated with a 13% increase in CHD risk and 33% increase in stroke risk, relative to working 35–40 hours. In further adjusted analyses, only the association between work hours and stroke remained significant, with a clear dose-response relation observed.
The authors conclude, “Our findings suggest that more attention should be paid to the management of vascular risk factors in individuals who work long hours.”
