Soldiers failing to meet Army Regulation 600-9 (AR 600-9) for weight-to-height standards are required to undergo body fat taping assessment. This article describes a clinical performance improvement project in which battalion medical staff identified a simpler way to improve on meeting AR 600-9 standards with proposing to use the waist-to-height ratio (WtHR) in place of the current methodology.
During a yearlong combat deployment to Iraq from 2009 to 2010, 42 Soldiers (34 males, 8 females) were evaluated and monitored by battalion medical staff for weight and body fat loss. Mean body mass index and waist circumference were compared between baseline or initial assessment and final assessment. The percentage of Soldiers meeting body fat standards was compared among those who had attained a WtHR ≤ 55% versus those who had not.
By the final assessment, mean body mass index had decreased 2.21 kg/m or 6.6% (p = 0.002) and mean waist circumference had decreased 6.0 cm or 5.8% (p = 0.008). All Soldiers who had attained a WtHR ≤ 55% met AR 600-9 body fat taping assessment standards and presented a professional military appearance.
Attaining a WtHR ≤ 55% is an effective measure of body composition that was able to predict a Soldiers' achievement of body fat standards metric for meeting AR 600-9 standards and achieving a professional military appearance.
未达到陆军条例600 - 9（AR 600 - 9）体重与身高标准的士兵需要接受体脂测量评估。本文描述了一个临床绩效改进项目，其中营级医务人员提出了一种更简单的方法来提高达到AR 600 - 9标准的情况，即提议使用腰高比（WtHR）取代当前方法。
在2009年至2010年为期一年的伊拉克作战部署期间，营级医务人员对42名士兵（34名男性，8名女性）的体重和体脂减少情况进行了评估和监测。比较了基线或初始评估与最终评估之间的平均体重指数和腰围。比较了达到WtHR≤55%的士兵与未达到该比例的士兵中符合体脂标准的百分比。
到最终评估时，平均体重指数下降了2.21 kg/m或6.6%（p = 0.002），平均腰围下降了6.0 cm或5.8%（p = 0.008）。所有达到WtHR≤55%的士兵都符合AR 600 - 9体脂测量评估标准，并呈现出专业军人的形象。
达到WtHR≤55%是一种有效的身体成分测量方法，能够预测士兵在达到AR 600 - 9标准和呈现专业军人形象方面的体脂标准指标达成情况。
