Soldiers work in various extreme environments, including the High Arctic, where energy requirements are increased compared with temperate climates. Soldiers often do not reach their energy needs with combat rations and face additional challenges to feeding in the Artic, which can hinder the performance. The purpose of this study is to document soldiers' perception about individual, dietary, and environmental factors influencing intake of combat rations during Arctic field training.
This qualitative phenomenological study included in-depth semi-structured individual interviews with 16 soldiers of the Canadian Armed Forces participating in the Arctic Operations Advisor training in Yellowknife (Northwest Territories) and Resolute Bay (Nunavut) from January to March 2019. Interviews were audio-recorded, transcribed verbatim, and then coded using a directed content analysis approach. Data were analyzed with NVivo qualitative data analysis software.
Five themes related to the individual (personal preferences; mood and morale), the diet (water availability; food variety), or the environment (meal preparation time) were identified. A sixth theme found was related to the diet and the environment (food/water temperature). Soldiers explained food and water were frozen, thus limiting water availability and greatly increasing meal preparation time. Food variety was deemed adequate by some, but others preferred more options. Individual food preferences and soldier mood and team morale could be barriers or facilitators to intake. Overall, the complexity of combat ration intake in the Arctic stemmed from the interaction of factors.
Various factors related to the individual, diet, and environment were found to influence intake of combat rations by participating soldiers during Arctic training. Reducing barriers to combat ration consumption by enhancing operational suitability of rations for the Arctic environment could promote dietary intake. Bearing in mind many interrelated factors influenced intake of soldiers, the military would benefit from further assessing which challenges related to intake in the field could be addressed.
士兵们在各种极端环境中执行任务,包括北极地区,与温带气候相比,那里的能量需求更高。士兵们通常无法通过战斗口粮满足其能量需求,并且在北极地区进食面临额外挑战,这可能会影响其表现。本研究的目的是记录士兵们对在北极野外训练期间影响战斗口粮摄入量的个人、饮食和环境因素的看法。
这项定性现象学研究包括对16名加拿大武装部队士兵进行深入的半结构化个人访谈,这些士兵于2019年1月至3月在耶洛奈夫(西北地区)和雷索卢特湾(努纳武特地区)参加北极行动顾问培训。访谈进行了录音,逐字转录,然后采用定向内容分析法进行编码。使用NVivo定性数据分析软件对数据进行分析。
确定了与个人(个人偏好;情绪和士气)、饮食(水的供应;食物种类)或环境( meal preparation time )相关的五个主题。发现的第六个主题与饮食和环境(食物/水的温度)有关。士兵们解释说食物和水都结冰了,从而限制了水的供应,并大大增加了 meal preparation time 。一些人认为食物种类足够,但其他人更喜欢更多选择。个人食物偏好以及士兵的情绪和团队士气可能成为摄入量的障碍或促进因素。总体而言,北极地区战斗口粮摄入的复杂性源于各种因素的相互作用。
研究发现,与个人、饮食和环境相关的各种因素会影响参与北极训练的士兵的战斗口粮摄入量。通过提高口粮对北极环境的作战适用性来减少战斗口粮消费的障碍,可以促进饮食摄入。鉴于许多相互关联的因素会影响士兵的摄入量,军方将受益于进一步评估哪些与野外摄入量相关的挑战可以得到解决。
