Key result
Working while ill did not act as a short-term trigger for a first coronary event compared to taking up to 14 days of sickness absence (OR 0.62; 95% CI 0.28-1.38).

Does working while ill trigger first coronary events in an occupational cohort?
Working while ill does not appear to act as a short-term trigger for serious coronary events.

No short-term triggering by working while ill; leaves open its contribution to long-term coronary risk in observational data.
OBJECTIVE: Working while ill has been found to predict coronary heart disease. We tested if this association was due to triggering. METHODS: We used a nested case-control study in an occupational cohort to examine sickness absences during a 2-year period immediately before the first coronary event for 133 cases and 928 matched controls without a history of coronary events. Working while ill was defined as no absence despite being unhealthy (suboptimal self-rated health or psychological distress). RESULTS: The odds of a coronary event were not higher for cases who worked while ill than for correspondingly unhealthy controls who took >0 to 14 days of absence per year (OR = 0.62; 95% CI = 0.28 to 1.38). These results were little affected by multiple adjustments. CONCLUSIONS: We found no evidence that working while ill acts as a short-term trigger for coronary events.

Westerlund et al. (2009) conducted a case-control in Coronary events (n=1,061). Working while ill (no absence despite being unhealthy) vs. Correspondingly unhealthy controls who took >0 to 14 days of absence per year was evaluated on First coronary event (OR 0.62, 95% CI 0.28 to 1.38). Working while ill did not act as a short-term trigger for a first coronary event compared to taking up to 14 days of sickness absence (OR 0.62; 95% CI 0.28-1.38).
