Very few studies on work related risk factors for myocardial infarctions has comprised women, Nevertheless, indications of different reactions to occupational psychosocial conditions have been found. The SHEEP study will include almost 1500 women - of which 50% are cases and 50% referents. Exposure information is requested in psychological demands, level of control, and social support at work, together with a large number of different exposures/factors. Given the high prevalence of exposure to strenuous psychosocial work environment (about 20% in the study base) and the number of cases and referents in SHEEP, the study will be able to detect also modest increased risks of myocardial infarction in women, due to psychosocial work environment factors. Shall be reported 1998.
