Psychosocial stress – typically resulting from difficulty coping with challenging environments – may work synergistically to put women at significantly higher risk of developing coronary heart disease, according to a study by researchers at Drexel University’s Dornsife School of Public Health, recently published in the Journal of the American Heart Association.
The study specifically suggests that the effects of job strain and social strain — the negative aspect of social relationships — on women is a powerful one-two punch. Together they are associated with a 21% higher risk of developing coronary heart disease. Job strain occurs when a woman has inadequate power in the workplace to respond to the job’s demands and expectations.
The study also found that high-stress life events, such as a spouse’s death, divorce/separation or physical or verbal abuse, as well as social strain, were each independently linked with a 12% and 9% higher risk of coronary heart disease, respectively.
The Drexel study used data from a nationally representative sample of 80,825 postmenopausal women from the Women’s Health Initiative Observational Study, which tracked participants from 1991 to 2015, to find better methods of preventing cancer, heart disease and osteoporosis in women. In the current follow-up study, Drexel researchers evaluated the effect of psychosocial stress from job strain, stressful life events and social strain (through a survey), and associations among these forms of stress, on coronary heart disease.
