Work stress increases the risk of cerebral ischemia

Work stress increases the risk of cerebral ischemia

Workers put a lot of pressure and unpredictable situations that have given up to 58% more likely to suffer from stroke.

Work in the services sector may increase to 58% the likelihood of cerebral ischemia. Jobs as a waiter, assistant nurse or firefighter are considered work with a level of as high stress are associated with an increased risk of stroke, according to an analysis of six major studies conducted by the American Academy of Neurology in the that a large section of population was analyzed for periods ranging from 3 to 17 years.

In this analysis, the experts defined as very stressful demanding jobs (pressure deadlines, psychological burdens, many demands …) and difficult to control, where unpredictable situations occur.

Between 11% and 27% of participants in the analyzed studies they were considered high-stress job and belonged to the services sector.

The most common strokes among the stressed workers are ischemic, caused by blockage of blood flow, hampering access of blood to the brain. People with very demanding jobs with little possibility of control are 58% more likely to suffer ischemia than those with quieter work.

It also happens, according to the investigation, but very demanding jobs where just unpredictable situations occur in the day, do not affect your chances of getting this type of ailment, as with architects or engineers.

Although cerebral hemorrhages are less common type of stroke than ischemia, the analysis found that also suffer as people with stressful jobs: they had a 22% increased risk of brain hemorrhage than those with quieter jobs. In women, the percentage increases to 33%.

But the type of work is not the only direct cause of these ailments, the American Academy of Neurology value options.

“Chances are that high stress jobs lead to less healthy behaviors, such as poor eating habits, smoking and lack of exercise, practices that increase the likelihood of having ischemia, “explains Xu Dingli, one of the managers of meta-analysis.

The American Academy of Neurology has reached these conclusions after analyzing the available research on job stress and risk of stroke. The studies analyzed include 138,782 participants who were followed from 3 to 17 years. “Having a stressful job has always been linked to heart disease, but so far the research linking stress and strokes have shown inconsistent results, “says Xu.

As shown in the report, the likelihood of stroke is as much with the requirement of work and the ability to control that held about it. “It is reasonable to assess the need for interventions to increase control in the work, such as decentralization of decision-making and flexibility in the structure of work, “said Jennifer J. Majersik, a member of the American Academy of Neurology.

Xu Dingli, one of the managers of the meta-analysis recognizes that research has several limitations, such as work stress was measured only at specific times during the period analyzed, and that other factors, such as blood pressure or cholesterol, were not well included in the original studies.

In addition, physical work and the total number of hours worked were not included. Although these drawbacks do not remove power to the results of this analysis, the authors say. The meta-analysis published in Wednesday’s edition online of Neurology, the medical journal of the American Academy of Neurology.
