Conclusions of the Study:


In this study we observed an increased risk of cardiovascular disease* among firefighters who had been employed between 20 and 29 years, but little or no excess among firefighters employed for 30 or more years. The increased risk among firefighters was strongest for acute coronary disease, a category consisting primarily of acute myocardial infarction. The patterns observed in this study do not fit the classic dose-response model with risks increasing with level of exposure and the highest risk observed in the highest exposure group. However, these results are compatible with a work-related effect for CVD accompanied by a strong survivor effect. The lack of an increased risk among the longest employed may reflect the survival in the profession of those with the highest relative level of fitness or lack of other co-factors that might contribute to lower base-line risk.

The major limitations of this study are the lack of better measures of exposure and of individual level information on other risk factors for CVD. The major strengths of this study are the improved information on cardiovascular disease through linkage with hospitalization and other records and the analysis which compared firefighters to other firefighters, addressing some of the concerns associated with the “healthy worker effect.”
