Characteristics and Predictors of Occupational Injury Among Career Firefighters.

The purpose of this study was to assess occupational injury characteristics and predictors among career firefighters. A total of 249 firefighters from central Texas and northern California participated in this Internet-based survey. Approximately 27% of firefighters had reported an occupational injury within the previous 12 months. The majority of injuries occurred on the scene of a non-fire call while performing an activity that required lifting, pushing, or pulling. Firefighters' backs were most frequently injured. Of the reported injuries, approximately 18% returned to work on modified duty, but 46% were not allowed to work due to their occupational injuries. Firefighters who reported occupational injuries were more likely to be older and experiencing occupational stress compared with their coworkers who did not report occupational injuries. Injured firefighters were also more likely to report fewer job rewards (money/salary), overcommitment, less esteem (respect and support), and fewer promotional prospects. These injury factors should be incorporated into interventions to reduce or prevent workplace injuries.

Accuracy of peak VO2 assessments in career firefighters.

BACKGROUND: Sudden cardiac death is the leading cause of on-duty death in United States firefighters. Accurately assessing cardiopulmonary capacity is critical to preventing, or reducing, cardiovascular events in this population. METHODS: A total of 83 male firefighters performed Wellness-Fitness Initiative (WFI) maximal exercise treadmill tests and direct peak VO2 assessments to volitional fatigue. Of the 83, 63 completed WFI sub-maximal exercise treadmill tests for comparison to directly measured peak VO2 and historical estimations. RESULTS: Maximal heart rates were overestimated by the traditional 220-age equation by about 5 beats per minute (p < .001). Peak VO2 was overestimated by the WFI maximal exercise treadmill and the historical WFI sub-maximal estimation by ~ 1MET and ~ 2 METs, respectively (p < 0.001). The revised 2008 WFI sub-maximal treadmill estimation was found to accurately estimate peak VO2 when compared to directly measured peak VO2. CONCLUSION: Accurate assessment of cardiopulmonary capacity is critical in determining appropriate duty assignments, and identification of potential cardiovascular problems, for firefighters. Estimation of cardiopulmonary fitness improves using the revised 2008 WFI sub-maximal equation.

Cardiovascular risk factors among career firefighters.

Sudden cardiac death is the leading cause of on-duty death among firefighters. Determining firefighters' risk of cardiovascular death or all-cause mortality, cardiovascular risk factor profiles, and energy demands while firefighting may aid in understanding why this occupational group is at risk for on-duty sudden cardiac death. A literature review conducted between 2006 and 2009 did not demonstrate that firefighters are at increased risk of all-cause death compared to the general population. In addition, cardiovascular risk profiles of firefighters are similar to those of the general population. Firefighters may be part of the national obesity epidemic; their hypertension and hypercholesteremia often are not diagnosed or are undertreated. The combination of personal cardiovascular risk factors and extreme physical work demands may contribute to sudden cardiac death in this population.
