Abstract
BACKGROUND: In the United States, over 50% of the deaths of on-duty firefighters are classified as sudden cardiac deaths. A holistic view of the multiple risk factors and their relation to the prevalence of cardiovascular disease (CVD) is necessary to determine a baseline for prevention.
METHODS: This study surveyed 154 firefighters in a large Midwestern county about their individual exposure to particulates, noise, heat stress, skin contamination, and physical stress; lifestyle factors such as exercise, diet, smoking, and alcohol consumption; health status; and demographic factors.
RESULTS: Consumption of whole grains and alcohol were associated with a reduction of the risk of heart disease, while higher Body Mass Index (BMI) scores and increasing age were associated with increased risk of heart disease.
CONCLUSIONS: Although firefighters are exposed to substantial occupational risks, only lifestyle factors were found to significantly predict CVD and related health issues. BMI is a modifiable risk factor, which, if controlled, could appreciably improve health outcomes.
