A sense of fair treatment in the workplace was associated with a reduced risk of coronary heart disease in a large long-term study of British office workers published in the October 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
People feel a sense of justice at work when they believe their supervisor considers their viewpoint, shares information concerning decision-making and treats individuals fairly and in a truthful manner, according to background information in the article. An earlier study had shown that employees had lower blood pressure on days spent working with a supervisor they perceived as fair. The authors suggest that it is plausible to connect a high level of justice with a reduction in chronic stress and its attendent association with coronary heart disease (CHD).
Mika Kivimaki, Ph.D., of the Finnish Institute of Occupational Health, Helsinki, Finland, and colleagues analyzed data from 6,442 male office staff in 20 civil service departments in London, England. Justice at work was measured at phase one (1985-1988) and two (1989-1990). Each participant was given a score based on a self-reported justice scale. They were divided into three groups based on their average score. Participants were followed for incidence of coronary heart disease from 1990 to 1999. Conventional risk factors for coronary heart disease were measured at phase one.
"These data enable us to determine whether the addition of justice would add to risk estimates based on other risk factors," the researchers write. "In the present study, we examined whether justice at work predicted incidence of new CHD among employees and whether this association was independent of coronary risk factors, including cholesterol concentration, hypertension, body mass index (BMI), smoking, alcohol consumption, physical inactivity, and other psychosocial characteristics of the work environment."
