The purpose of this study was to assess the dietary habits, prevalence of low energy availability (EA), and sleep quality in a cohort of male army Reserve Officer Training Corps (ROTC) cadets, and to investigate the relationship between EA and sleep quality as well as EA and various body composition variables that are important for tactical readiness. Thirteen male army ROTC cadets (22.2 ± 4.1 yrs; BMI: 26.1 ± 2.3) had their EA and body composition assessed using diet and exercise records alongside bioelectrical impedance analysis. Cadets also completed a validated sleep questionnaire. Sixty-two percent of participants presented with clinically low EA (<30 kcal/kg fat-free mass [FFM]) and none met the optimum EA threshold (≥45 kcal/kg FFM). Dietary analysis indicated that 15%, 23%, 46%, 23%, and 7% of cadets met the Military Dietary Reference Intakes (MDRI) for calories, carbohydrates, protein, fat, and fiber, respectively. Additionally, 85% of cadets exhibited poor sleep quality. Significant associations between EA and fat mass/percent body fat were shown ( < 0.05). There was, however, no statistically significant correlation between EA and sleep quality. The present study found a high prevalence of low EA and sleep disturbance among male army ROTC cadets and that many were unable to meet the MDRIs for energy and macronutrient intake. Further, low EA was associated with higher percent body fat and fat mass but not sleep quality.
本研究的目的是评估一群男性陆军后备军官训练团（ROTC）学员的饮食习惯、低能量可利用性（EA）患病率和睡眠质量，并调查EA与睡眠质量以及EA与对战术准备很重要的各种身体成分变量之间的关系。13名男性陆军ROTC学员（22.2±4.1岁；BMI：26.1±2.3）通过饮食和运动记录以及生物电阻抗分析对其EA和身体成分进行了评估。学员们还完成了一份经过验证的睡眠问卷。62%的参与者呈现出临床上的低EA（<30千卡/千克去脂体重[FFM]），且无人达到最佳EA阈值（≥45千卡/千克FFM）。饮食分析表明，分别有15%、23%、46%、23%和7%的学员达到了卡路里、碳水化合物、蛋白质、脂肪和纤维的军事饮食参考摄入量（MDRI）。此外，85%的学员睡眠质量较差。EA与脂肪量/体脂百分比之间存在显著关联（<0.05）。然而，EA与睡眠质量之间没有统计学上的显著相关性。本研究发现男性陆军ROTC学员中低EA和睡眠障碍的患病率很高，而且许多人无法达到能量和宏量营养素摄入的MDRI。此外，低EA与较高的体脂百分比和脂肪量相关，但与睡眠质量无关。
