HELSINKI (Reuters) – A person's ability to cope with stress may help physicians predict their risk of heart and vascular diseases, a Finnish study found.
While stress has long been considered a risk factor for cardiovascular diseases, the concept of stress has been vague, Dr. Keltikangas-Jarvinen, professor of psychology at the University of Helsinki, told a news conference. "Temperament has not [previously] been seen as a risk factor" for cardiovascular diseases, she added.
New findings from a study begun over 20 years ago by five Finnish universities showed that a combination of a demanding family environment, dissatisfied parents and a temperament that copes poorly with stress raised the risk of physical illness.
The study of 3600 people linking physical and psychological factors to cardiovascular diseases, is the longest of its kind, Dr. Keltikangas-Jarvinen said. "A person's temperament determines what he considers stress and how he reacts or what kinds of physical reactions emerge during stress," she added.
"One cannot say what kind of stress is physiologically dangerous for people," Dr. Keltikangas-Jarvinen said. "It is how they feel the stress which determines whether they will get ill or not," she noted.
An easily stressed person who was brought up in a stress-causing environment had an increased risk of developing cardiovascular disease, Dr. Keltikangas-Jarvinen said.
One risk factor was a family environment where the child did not get emotional support, where he or she was not accepted, and where goals set for the child were extremely high.
Further risks were parents who were not satisfied with their lives–such as career-oriented mothers who had cold and distant relationships with their children–and who compensated for this dissatisfaction by working hard, Dr. Keltikangas-Jarvinen said.
There were also differences between the sexes in terms of the temperament types that were considered risky. Women who were dependent on social support did well but men who needed positive feedback were unable to see the physical warning signs their bodies were sending them during stress and faced a greater risk of heart disease.
Perfectionism was a risk factor for women but was not a problem for men, the study found.
