AsianScientist (May 22, 2013) – Middle-aged women who have depression are almost twice as likely to have a stroke as women the same age who are not depressed, according to a new Australian study.
The study, published in Stroke: Journal of the American Heart Association and led by Dr. Caroline Jackson from The University of Queensland’s School of Population Health, found that even after accounting for other stroke risk factors such as high blood pressure and diabetes, middle-aged women who were depressed were 1.9 times more likely to have a stroke than women without depression.
Jackson said the findings highlight the serious impact poor mental health can have on physical health.
“Current guidelines for stroke prevention tend to overlook the potential role of depression,” she said.
This research is the first large-scale study to examine the association between depression and stroke in women in their 40s and 50s, and draws upon the Australian Longitudinal Study on Women’s Health, a 12-year study of more than 10,000 Australian women aged between 47- and 52-years-old.
About 24 percent of study participants were reported as being depressed, based on their responses to a standardized depression scale and recent use of medication for depression. It was unclear why depression was so strongly linked to stroke in this age group but the body’s inflammatory and immunological processes and their effects on blood vessels may play a part, said Jackson.
She added that although the absolute risk of stroke for this age group was still very low — about two percent, it highlighted the need for better and more targeted approaches to preventing and treating depression in middle-aged women.
