Iron is a micronutrient necessary for energy metabolism and for oxygen transport and delivery. Depletion of iron stores (iron deficiency [ID]) may lead to iron deficiency anemia (IDA), which affects mood, cognitive function, and physical performance. Previous studies indicated that iron status may decline during military training. This study assessed the iron status and prevalence of ID and IDA in military personnel deployed to Bagram Air Base, Afghanistan (1492 m). Within the pool of 294 participants (149 male and 145 female), 2 males (1%) and 8 females (6%) presented with ID. Although IDA was not observed in males, 3 females (2%) met the criteria for IDA. Female sex (p = 0.05) and self-reported history of anemia (p < 0.05) were associated with diminished iron status. Amenorrhea was associated with higher ferritin (p < 0.05) and hemoglobin (p < 0.05) levels. Although ID and IDA did not affect a large portion of the deployed population assessed in this study, findings suggest that risk factors including female sex, history of anemia, and regular menstruation should be considered in the assessment of iron status in military personnel.
铁是能量代谢以及氧气运输和输送所必需的一种微量营养素。铁储备耗竭（缺铁[ID]）可能会导致缺铁性贫血（IDA），这会影响情绪、认知功能和身体表现。先前的研究表明，在军事训练期间铁状态可能会下降。本研究评估了部署到阿富汗巴格拉姆空军基地（海拔1492米）的军事人员的铁状态以及ID和IDA的患病率。在294名参与者（149名男性和145名女性）中，有2名男性（1%）和8名女性（6%）存在缺铁情况。虽然男性未观察到IDA，但有3名女性（2%）符合IDA标准。女性性别（p = 0.05）和自我报告的贫血病史（p < 0.05）与铁状态降低有关。闭经与较高的铁蛋白水平（p < 0.05）和血红蛋白水平（p < 0.05）有关。虽然ID和IDA并未影响本研究中所评估的大部分部署人员，但研究结果表明，在评估军事人员的铁状态时应考虑包括女性性别、贫血病史和规律月经等风险因素。
