Risk estimates for job strain were calculated by comparing the high-strain group with the low-strain group (exception Eaker et al.: high-strain group is the reference group). In most cases, hazard ratios or relative PRIMA-1MET risks were Thalidomide estimated, and in case of other statistical analyses, p values or level of significance is indicated eBlood pressure,

and/or lipids, and/or fibrinogen and/or BMI, and/or diabetes are considered as biological risk factors. Smoking, and/or alcohol, and/or low physical activity are considered as behavioural risk factors. SBP systolic blood pressure, DBP diastolic blood pressure, BMI body mass index, LDL low-density lipoprotein In the majority of the cohorts, participants were recruited from an unselected general working population. The remaining studies included selected occupations or companies (see Tables 1, 2, 3 for details). Nine cohorts investigated only men and three cohorts only women. Twelve publications (eight cohorts) described both men and women. Ten of the 15 analyses examining only male participants yielded significant positive results, whereas only one of the nine analyses observing exclusively women showed significant positive results. In summary, statistically significant associations between psychosocial stress and cardiovascular disease were described in 14 out of 26 publications (11 out of 20 cohorts, respectively). With the exception of the Nurses Health Study (Lee et al. 2002), all studies that reported risk estimates indicated a higher risk of cardiovascular diseases with increasing stress. However, not all of these results were statistically significant.
