BACKGROUND: Covert coping with unfair treatment at work--occurring when an employee does not show the "aggressor" that he/she feels unfairly treated--has been found to be associated with cardiovascular risk factors. This study examined whether covert coping also predicts incident coronary heart disease. METHODS: A prospective cohort study (the WOLF Stockholm study) of workplaces in the Stockholm area, Sweden. The participants were 2755 men with no history of myocardial infarction at baseline screening in 1992-1995. The main outcome measure was hospitalisation due to myocardial infarction or death from ischaemic heart disease until 2003 obtained from national registers (mean follow-up 9.8 ± 0.9 years). RESULTS: Forty-seven participants had myocardial infarction or died from ischaemic heart disease during follow-up. After adjustment for age, socioeconomic factors, risk behaviours, job strain and biological risk factors at baseline, there was a dose-response relationship between covert coping and risk of incident myocardial infarction or cardiac death (p for trend=0.10). Men who frequently used covert coping had a 2.29 (95% CI 1.00 to 5.29) times higher risk than those who did not use coping. Restricting the analysis to direct coping behaviours only strengthened this association (p for trend=0.02). CONCLUSIONS: In this study, covert coping is strongly related to increased risk of hard-endpoint cardiovascular disease.
