Can Work Stress be Linked to Stroke?
According to a meta-analysis published in the journal Neurology, having a high-stress job may be linked to a higher risk of stroke. The analysis looked at all of the available research on job strain and stroke risk. The six studies analyzed involved a total of 138,782 participants who were followed for three to 17 years. Jobs were classified into four groups based on how much control workers had over their jobs and how hard they worked, or the psychological demands of the job. The job demands included time pressure, mental load and coordination burdens. Physical labor and total number of hours worked were not included. The analysis found that people with high stress jobs had a 22 percent higher risk of stroke than those with low stress jobs. Women with high stress jobs had a 33 percent higher risk of stroke than women with low stress jobs. People with high stress jobs were 58 percent more likely to have an ischemic stroke than those with low stress jobs. Ischemic stroke, which is the most common type of stroke, is caused by blockage of blood flow. People in passive and active jobs did not have any increased risk of stroke. The researchers calculated that 4.4 percent of the stroke risk was due to the high stress jobs. For women, that number increased to 6.5 percent. Based on this study, researchers say it’s reasonable to consider testing interventions aimed at increasing job control, such as decentralization of decision-making and flexibility in job structure, such as telecommuting.
