Reporting tendency, angina, ischaemia and mortality according to level of perceived psychological stress at baseline
| Incident angina* (odds ratio (95% CI)) | Incident ischaemia† (odds ratio (95% CI)) | All cause mortality (hazard ratio (95% CI)) | CHD mortality (hazard ratio (95% CI)) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Perceived stress | Mean reporting tendency score | Adjustment A | Adjustment B | Adjustment A | Adjustment B | Adjustment A | Adjustment B | Adjustment A | Adjustment B |
| Adjustment A – age, occupational class, smoking (cigarettes smoked daily, ex, current, never smokers), alcohol consumption (0, >0–15, >15 units weekly), weekly hours of exercise, diastolic blood pressure (mm Hg), cholesterol (mmol/l), body mass index (kg/m2), lung function (observed FEV1 as % of expected). Adjustment B – all above and reporting tendency score. *Definite angina taken as pain or discomfort over the sternum or left chest and arm while hurrying or walking uphill causing the participant to slow down or stop, the pain subsiding in 10 minutes or less. Excluding participants with angina at recruitment and those not screened twice, High stress – n=310; Medium stress – n=1328; Low stress – n=834; †definite ischaemia encompassed by Minnesota codes 1.1–1.3, 4.1–4.4, 5.1–5.3 and 7.1. Excluding participants with ischaemia at recruitment and those not screened twice, High stress – n=335; Medium stress – n=1340; Low stress – n=812. | |||||||||
