“…In the current study, firefighters had high levels of sodium intake and low levels of fiber, according to the MDRI standards [ 5 ]. Protein intake from self-reported three-day food records in overweight and obese career firefighters averaged 17% of total calories [ 14 ]. In our sample, the mean BMI was 28.3 kg/m 2 and protein intake averaged 21.9% of total calories.…”

The primary goals of the Dietary Reference Intakes (DRI) are to plan and assess nutrient intakes to promote health, reduce chronic disease, and prevent toxicity. Firefighters have unique nutrient needs compared to the public due to their job demands. The military provides the only published guidance for tactical athletes’ nutrient needs. The purpose of this study was to determine whether firefighters were meeting the Military Dietary Reference Intakes (MDRI). A cross-sectional study was conducted in a sample of career firefighters (n = 150, 37.4 ± 8.4 year-old males) employed in Southern California. Data were gathered during baseline assessments from a Federal Emergency Management Agency-funded Firefighter Wellness Initiative. Participants were asked to log their food and beverage consumption over a 72-h period. Descriptive statistics (means, standard deviations, 95% confidence intervals) were calculated for all participant characteristics and average three-day nutrient intakes. A 95% confidence interval compared their nutrient intake to MDRI to identify differences in nutrient intakes, significance accepted at p = 0.05. Compared to MDRI reference values, firefighters consumed an inadequate amount of total calories, linolenic and alpha-linolenic fatty acid, fiber, vitamins D, E, and K, potassium, magnesium, zinc, and carbohydrates. Vitamin D, magnesium, and potassium had the greatest shortcomings (95.3%, 94.0%, and 98.7%, respectively, under MRDA). Thus, firefighters are not meeting the established MDRI for several key nutrients required to promote health, improve performance, and reduce chronic disease. Dietitians and health care providers may use the results of this study to help design health promotion programs for this population. Future research should develop a customized reference intake for firefighters.

“…Given the descriptive nature of the current study, a sample size of n = 150 was adequate to achieve the study’s aims. The selected sample size is larger than other studies assessing nutritional intake in firefighters and military personnel [ 10 , 11 , 13 , 14 ].…”

“…Protein intake from self-reported 3-Day Food Records in overweight and obese career firefighters averaged 17% of total calories. Greater protein intake was associated with less body fat percent (Hirsch et al, 2018). In general, firefighter populations are overconsuming carbohydrates and sodium, while under consuming fiber, potassium, vitamin D and E (Robertson et al, 2017).…”

The final nutrition variables selected are strongly correlated with health and performance for general populations (Broussard et al, 2015;Halson, 2014) and firefighters (Hirsch et al, 2018;McDonough, Phillips, & Twilbeck, 2015;Wooding et al, 2018).

“…Given the physical demands of job-tasks, the upper end of the AMDR was selected. Based on previous research findings, firefighters are under consuming protein and higher protein intake is beneficial for healthy body composition (Hirsch et al, 2018). Given the correlation of body composition and injury risk in firefighters (Jahnke et al, 2013;Kuehl et al, 2013), adequate protein intake is critical.…”

Tactical athletes are at high risk for numerous conditions that are susceptible to nutritional intake. However, nutrition risk assessments in tactical athletes are not routinely implemented. The purpose of this paper was to describe preliminary development of the Tactical Athlete Nutrition Score (TANS). A cross-sectional study was conducted in a convenience sample of career firefighters (N = 150, all males) in southern California. Participants completed a 3-Day Food Record and other health-related questionnaires, and anthropometric measurements. The TANS was developed through best available evidence, observations, and an expert judgment exercise. The TANS include five variables: total energy, protein, omega-3 fatty acids, total sugar, and fruit and vegetable consumption. Risk levels were quantified according to data from these categories and analyzed accordingly. The TANS appeared to effectively differentiate individuals based on nutrition risk, with separation observed among the TANS risk levels – low risk (n = 7), moderate risk (n = 77), high risk (n = 66). One-way analysis of variance revealed significant difference among the risk categories for the five nutrition variables and TANS total (p < 0.001). The observed risk categories are plausible based on knowledge of this population. This study suggests the TANS is feasible to proceed to full-scale validation research trials. If validity is established, TANS will contribute to assessing nutrition risk level and improving nutrition interventions among tactical athletes.
