“…One possible explanation for these differences is that the present analysis employed a case‐control analytic method while a number of papers included in the Jalilian meta‐analysis compared firefighter incidence rates with general population incidence rates 6 . As indicated earlier, this latter approach can be more susceptible to underestimating true risk given the healthy worker effect 24,32 . Of note, nine of the 29 cancer incidence studies included in the Jalilian meta‐analysis calculations, 6 including the initial Florida analysis, 19 employed national or regional comparators in their SIR calculations (see Table S5) 6 …”

Background Firefighters are at increased risk for select cancers. However, many studies are limited by relatively small samples, with virtually no data on the cancer experience of female firefighters. This study examines cancer risk in over 100,000 career Florida firefighters including 5000 + females assessed over a 34‐year period. Methods Florida firefighter employment records (n = 109 009) were linked with Florida Cancer Data System registry data (1981‐2014; ~3.3 million records), identifying 3760 male and 168 female‐linked primary cancers. Gender‐specific age and calendar year‐adjusted odds ratios (aOR) and 95% confidence intervals for firefighters vs non‐firefighters were calculated. Results Male firefighters were at increased risk of melanoma (aOR = 1.56; 1.39‐1.76), prostate (1.36; 1.27‐1.46), testicular (1.66; 1.34‐2.06), thyroid (2.17; 1.78‐2.66) and late‐stage colon cancer (1.19;1.00‐1.41). Female firefighters showed significantly elevated risk of brain (2.54; 1.19‐5.42) and thyroid (2.42; 1.56‐3.74) cancers and an elevated risk of melanoma that approached statistical significance (1.68; 0.97‐2.90). Among male firefighters there was additional evidence of increased cancer risk younger than the age of 50 vs 50 years and older for thyroid (2.55; 1.96‐3.31 vs 1.69; 1.22‐2.34), prostate (1.88; 1.49‐2.36 vs 1.36; 1.26‐1.47), testicular (1.60; 1.28‐2.01 vs 1.47; 0.73‐2.94), and melanoma (1.87; 1.55‐2.26 vs 1.42; 1.22‐1.66) cancers. Conclusion Male career firefighters in Florida are at increased risk for five cancers with typically stronger associations in those diagnosed younger than the age of 50, while there was evidence for increased thyroid and brain cancer, and possibly melanoma risk in female firefighters. Larger cohorts with adequate female representation, along with the collection of well‐characterized exposure histories, are needed to more precisely examine cancer risk in this occupational group.

“…For example, aerobic capacity is an important contributing factor of performance on many firefighting tasks, particularly those that involve fire suppression . Firefighters with higher aerobic capacity and lower fat mass perform job tasks faster, and with increased efficiency while working with their self‐contained breathing apparatus . Therefore, exercise could be implemented to improve aerobic capacity which could lead to improved performance.…”

Objective The present review synthesized the available empirical evidence to provide support of the effectiveness and feasibility of exercise interventions for improving health and fitness of firefighters. Methods Nine randomized controlled trials (RCTs) published before May 2018 were located using Google Scholar, MEDLINE, PsycINFO, PubMed, and Web of Science. RCTs involved 462 (18 Females) active‐duty firefighters, an exercise intervention, and reported changes in health and/or fitness. Hedges’ d effect sizes quantified the magnitude of the effects of exercise compared to control conditions. Aggregated mean effects for differential modes of exercise (aerobic exercise training (AET), resistance exercise training (RET), or combined (AET + RET)) were also calculated. Random effects models were used for all analyses. Results Exercise significantly improved body fat percentage (Δ = 0.52, [95% CI: 0.16‐0.88] z = 2.81, P = 0.005, k = 4), aerobic capacity (Δ = 1.20, [0.52‐1.87] z = 3.48, P = 0.000, k = 8), endurance (Δ = 1.74, [0.94‐2.53] z = 4.03, P = 0.000, k = 10), strength (Δ = 1.27, [0.42‐2.11] z = 2.93, P = 0.003, k = 9), and power (Δ = 1.02, [0.52‐1.52] z = 4.00, P = 0.000, k = 2). Specifically, RET improved body fat percentage (Δ = 0.87, [0.38‐1.36] z = 3.47, P = 0.000, k = 2), aerobic capacity (Δ = 3.06, [2.37‐3.75] z = 8.65, P = 0.000, k = 2), endurance (Δ = 2.79, [1.48‐4.09] z = 4.19, P = 0.000, k = 6), strength (Δ = 1.44, [0.49‐2.39] z = 2.97, P = 0.002, k = 8), and power (Δ = 1.02, [0.52‐1.52] z = 3.99, P = 0.000, k = 2), while AET improved aerobic capacity (Δ = 0.69, [0.24‐1.15] z = 3.01, P = 0.000, k = 3), and AET + RET improved aerobic capacity (Δ = 0.52, [0.15‐0.89] z = 2.78, P = 0.005, k = 3) and endurance (Δ = 0.44, [0.19‐0.70] z = 3.41, P = 0.000, k = 3). Conclusions The present results provide evidence of the positive effects of exercise interventions, particularly RET, to improve outcomes of health and fitness associated with superior job performance and reduced risk of injury and CVD.

“…One study found that firefighters who had lower VO 2 max scores were more likely to sustain an injury [ 4 ]. Another study found that those who had higher VO 2 max scores performed better on a firefighting simulation test [ 16 ]. Both studies indicated that firefighters with a better VO 2 max had better outcomes, whether that be injury occurrence or performance.…”

Background The Functional Movement Screen (FMS™) is a screening tool used to assess an individual's ability to perform fundamental movements that are necessary to do physically active tasks. The purpose of this study was to assess the ability of FMS to predict occupational injury among Denver Fire Department firefighters. Method FMS tests were administered from 2012 to 2016. Claim status was defined as any claim occurrence vs. no claim and an overexertion vs. no claim/other claim within 1 year of the FMS. To assess associations between FMS score and claim status, FMS scores were dichotomized into ≤14 and > 14. Age-adjusted odds ratios were calculated using logistic regression. Sensitivities and specificities of FMS predicting claims at various FMS score cut points, ranging from 10 to 20 were tested. Results Of 581 firefighters (mean ± SD, age 38 ± 9.8 y) who completed FMS between February 2015 and March 2018, 188 (32.4%) filed a WC claim in the study time frame. Seventy-two of those (38.3%) were categorized as overexertion claims. There was no association between FMS score and claim status [odds ratio (OR) = 1.27, 95% confidence interval (CI): 0.88 – 1.83] and overexertion claim vs. no claim/other claim (OR = 1.33, 95% CI: 0.81 – 2.21). There was no optimal cutoff for FMS in predicting a WC claim. Conclusions Although the FMS has been predictive of injuries in other populations, among this sample of firefighters, it was not predictive of a future WC claim.

Physical and Physiological Performance Determinants of a Firefighting Simulation Test

Abstract: Firefighter simulation test performance is associated with absolute cardiorespiratory fitness and fat mass. Fitter and leaner individuals perform the task more quickly. Work-based interventions should enhance these attributes to promote safe and effective operational performance.
