Psychosocial stress linked to higher stroke risk

In a study from the National University of Ireland Galway, scientists found that self-reported psychosocial stress is associated with an increased risk for stroke.

They examined whether psychosocial stress is associated with the risk of acute stroke.

The analysis included 13,462 patients with first acute stroke in 32 countries in Asia, North and South America, Europe, Australia, the Middle East, and Africa, and 13,488 matched controls.

The researchers found that increased stress at home (odds ratio, 1.95), stress at work, and recent stressful life events were linked to an increased risk for stroke.

There were reduced odds of stroke seen for those reporting higher locus of control at home.

A higher locus of control both at work and at home was associated with lower odds of acute stroke and strongly lessened the association of stress at work and home with the risk for acute stroke.

The team says psychosocial stress is a common risk factor for acute stroke.

The findings of this case-control study suggest that a higher locus of control is linked to a lower risk of stroke and may be an important effect modifier of the risk associated with psychosocial stress.
