Long-term stress suffered by women leads to some form of physical complaint in four out of ten cases.
This link between stress and illness was reported in a new study from the Sahlgrenska Academy, University of Gothenburg, Sweden.
Within the Population Study of Women in Gothenburg, researchers at the Sahlgrenska Academy have followed around 1,500 women since the late 1960s.
The latest study within the project showed that one in five middle-aged women had experienced constant or frequent stress during the last five years.
The experience of stress was highest within the 40 to 60 age range, and those women who were stressed were more often single or smokers.

Among those women who reported stress, 40 percent had psychosomatic symptoms in the form of aches and pain in their muscles and joints, 28 percent suffered from headaches or migraines, and the same proportion reported gastrointestinal complaints.
“Even when the results have been adjusted for smoking, BMI and physical activity, we can see a clear link between perceived stress and an increased incidence of psychosomatic symptoms,” says Dominique Hange, researcher at the Sahlgrenska Academy.
Of those women who experienced long-term stress but who did not report any stress-related problems when the study began in 1968-69, 27 percent had new symptoms in the form of muscular and joint pain when they were followed up 12 years later, and around 15 percent experienced new complaints in the form of headaches and/or gastrointestinal problems.
“Since 1968, women’s lifestyles have changed in many ways,” continues Dominique Hange. “For example, many more women now work outside the home. Naturally, these changes can affect the experience of stress.
“The most important conclusion is that single women, women who do not work outside the home and women who smoke are particularly vulnerable to stress. Here, we see a greater need for preventive measures from society.”
The next stage will involve the researchers evaluating which methods can be used within healthcare, particularly within primary care, in order to help the individual to deal with stress-triggered complaints and illnesses.
