In addition, job insecurity – fear of losing one's job – was associated with risk factors for cardiovascular disease such as high blood pressure, increased cholesterol and excess body weight. However, it'snot directly associated with heart attacks, stroke, invasive heart procedures or cardiovascular death, researchers said.
Job strain, a form of psychological stress, is defined as having a demanding job, but little to no decision-making authority or opportunities to use one's creative or individual skills.
"Our study indicates that there are both immediate and long-term clinically documented cardiovascular health effects of job strain in women," said Michelle A. Albert, M.D., M.P.H., the study's senior author and associate physician at Brigham and Women's Hospital, Boston, Mass. "Your job can positively and negatively affect health, making it important to pay attention to the stresses of your job as part of your total health package."
Researchers analyzed job strain in 17,415 healthy women who participated in the landmark Women's Health Study. The women were primarily Caucasian health professionals, average age 57 who provided information about heart disease risk factors, job strain and job insecurity. They were followed for more than 10 years to track the development of cardiovascular disease. Researchers used a standard questionnaire to evaluate job strain and job insecurity with statements such as: "My job requires working very fast." "My job requires working very hard." "I am free from competing demands that others make."
The 40 percent higher risks for women who reported high job strain included heart attacks, ischemic strokes, coronary artery bypass surgery or balloon angioplasty and death. The increased risk of heart attack was about 88 percent, while the risk of bypass surgery or invasive procedure was about 43 percent.
"Women in jobs characterized by high demands and low control, as well as jobs with high demands but a high sense of control are at higher risk for heart disease long term," said Natalie Slopen, Sc.D., lead researcher and a postdoctoral research fellow at Harvard University Center on the Developing Child in Boston.
Previous research on the effects of job strain has focused on men and had a more restricted set of cardiovascular conditions. "From a public health perspective, it's crucial for employers, potential patients, as well as government and hospitals entities to monitor perceived employee job strain and initiate programs to alleviate job strain and perhaps positively impact prevention of heart disease," Albert said.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
