Title
Factors influencing the dietary intake of military members in the Canadian Armed Forces working in the Arctic
Names, Organizational Affiliations, and Locations of all Authors
Introduction/Purpose
Military members in the Canadian Armed Forces (CAF) do not consistently meet their daily energy needs with combat rations when working in harsh environments, like the Arctic. Low dietary intakes over a prolonged period can contribute to involuntary weight losses and diminished performance and increase the risk of injury. Many factors are thought to influence soldiers’ dietary intake.
Objective(s)/Process or Summary of Content
This study aimed to determine CAF members perception of individual, dietary, and environmental factors influencing food intake while working in the Arctic.
Method(s)/Systemic Approach Used
A survey was sent nationally with SurveyMonkey July-September 2018 to military members who worked in the Arctic 2015-2018. The survey included questions on demographics, physical markers, acceptability of rations, eating habits, and diet history during Arctic work. The 20-minute survey had 39 open and closed-ended questions, including some on food variety, amount of food eaten, time for meals, ability to heat rations, hunger, and weight changes. Excel was used to compile descriptive statistics.
Results/Conclusions
The survey response rate was 27.5%. Soldiers (n=37) and instructors (n=11) participated (ages 31.7±7.2years; 45 men, 3 women). They reported that 61%, 68%, and 71% of breakfast, lunch, and supper rations were eaten. Two participants reported not having enough time to eat. Eating on the move, weather/environmental conditions, and equipment required for food preparation and consumption were factors that negatively affected the most dietary intake of military members during Arctic exercises. Sixty-five percent (n=31) self-reported losing weight during their exercise (1.8−11.3kg).
Conclusions(s)/Recommendations
Preliminary results showed that many factors influenced the dietary intake of CAF members working in the Arctic. Lack of time did not seem to limit intake. More research is needed to accurately measure weight change during these exercises and explore options to make rations better adapted for the Arctic.
Significance to Dietetics
These results may help dietitians develop rations better suited for this population.
