Researchers Link Longer Works Hours To Stroke Risk


By -

This one maybe a no-brainer and a wake up call to workaholics. A new research done on some 600,000 individuals in the United States, Europe and Australia says that the risk of stroke and coronary heart disease goes up significantly in people who work longer hours. The study however, was not designed to analyse the underlying causes or account for all the factors that contributed to the increased risk.

Dr. Urban Janlert, a professor of public health at Umea University in Sweden remarked that long work hours had previously pointed towards increased risk of heart disease but a connection to stroke was “surprising”. The study showed that people who worked 55 hours or more per week recorded a 13% greater risk of coronary heart disease and a 33% greater risk of stroke. Mika Kivimaki, a professor of epidemiology at University College London, and his colleagues combined the results of many studies and even unpublished material from public databases.

For stroke, the study monitored some 528,908 men and women who worked 55 hours or more instead of the standard 35-40 hours a week. This study lasted a period of 7.2 years and recorded 1722 fatal and non fatal strokes. The study controlled for factors including smoking, physical activity and high blood pressure and cholesterol.

For coronary heart disease, 603838 were monitored over 8.5 years. After controlling for age, sex and socioeconomic status, 4768 people were diagnosed with coronary heart disease as a cause of death or hospitalization.

This research received a lot of criticism from different doctors and specialists who pointed out that this study was not purely objective in that it didn’t use studies with a clear objective of proving a link between the two diseases and longer work hours or didn’t account for enough factors. But it doesn’t take a genius to fathom that if you over work yourself you will crash.
