Tactical personnel (including military, law enforcement, and fire and rescue) are responsible for ensuring national and public safety. Dietary intake is an important consideration to support optimal health and performance. The aims of this systematic review were to: (1) describe the reported free-living dietary intake (energy and macronutrients) of tactical personnel, and (2) describe the practical implications of reported dietary intakes to support the physical and dietary requirements of tactical personnel. A systematic search of databases (MEDLINE, EMBASE, CINAHL and Web of Science) was conducted following the PRISMA guidelines. English and full text research articles were identified and screened against inclusion and exclusion criteria. Demographic and dietary intake data were extracted, tabulated, and synthesized narratively. The quality of the studies was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist. Twenty-two studies (15 military, 4 law enforcement, and 2 fire and rescue) were eligible to inform this review. The volume of evidence suggested that tactical personnel met dietary protein and exceeded dietary fat recommendations but failed to meet energy and carbohydrate recommendations. Therefore, practical approaches to support optimized energy, fat and carbohydrate intake in tactical personnel is important.

Background: Law enforcement is a dangerous, stressful, and health-threatening occupation. This study investigated the association between demographic factors including sex, age, and types of law enforcement occupation and described self-reported barriers to healthy and enjoyable diets within a cohort of law enforcement personnel. Methods: This mixed-methods study explored cross-sectional data from the Perceived Barriers to Healthy Eating validated survey. The survey included eight questions obtaining quantitative data and two open ended question obtaining qualitative data. A framework thematic analysis using the theory of planned behavior was undertaken to describe self-reported barriers to a healthy and enjoyable dietary intake. Results: 159 participants (median age = 27 (range 19–60) years; 74% males) were surveyed. In general, demographic factors are not associated with the dietary beliefs and behavior of law enforcement personnel. Self-reported barriers (generated themes) to a healthy and enjoyable diet included individual preferences, social influences, internal drive, capacity to change and occupational influences, which broadly aligned with the theory of planned behavior. Conclusions: Dietary intake in law enforcement personnel is impacted by occupational considerations, including busy schedules, long working hours, inconsistent meal breaks, tiredness, and shift work. The study provides useful information to support dietary interventions.
