To comply with Army Regulation 600-9, The Army Weight Control Program (AWCP), soldiers must meet age-adjusted body fat standards, regardless of whether they meet or exceed weight-for-height allowances. Recent revisions to Department of Defense (DoD) policies require changes to the AWCP. Specifically, we assessed the effects of increasing weight-for-height allowances and adoption of the DoD body fat equation on compliance with the AWCP in women.
Weight, height, circumferences (neck, forearm, wrist, waist, and hip) to measure body fat, and Army Physical Fitness Test results were obtained from 909 female soldiers (mean (SD) age, 26.2 (6.5) years; body mass index, 24.6 (3.3) kg/m2; body fat, 29.7% (5.0)).
Increasing the screening weight-for-height allowances resulted in a 20% reduction in those requiring a body fat measurement (from 55% [n = 498) to 35% [n = 319]). Adopting the DoD body fat equation did not change the proportion of overfat women, i.e., noncompliant with the AWCP, (from 26% [n = 232] to 27% [n = 246]). More women with a waist circumference > 35 inches (i.e., at increased disease risk) were identified as noncompliant with the AWCP by the proposed body fat equation (from 76% [n = 61] to 96% [n = 77]).
Proposed changes reduce the proportion of women unnecessarily measured for body fat and do not change the proportion of women on the AWCP, yet select more women at increased disease risk and most in need of an effective intervention.
为遵守陆军条例600 - 9《陆军体重控制计划》(AWCP),士兵必须达到根据年龄调整的体脂标准,无论其体重是否符合或超过身高对应的体重允许范围。美国国防部(DoD)政策的近期修订要求对AWCP进行调整。具体而言,我们评估了提高身高对应的体重允许范围以及采用国防部体脂计算公式对女性遵守AWCP情况的影响。
获取了909名女性士兵的体重、身高、用于测量体脂的周长(颈部、前臂、手腕、腰部和臀部)以及陆军体能测试结果(平均(标准差)年龄,26.2(6.5)岁;体重指数,24.(3.3)kg/m²;体脂,29.7%(5.0))。
提高筛查时身高对应的体重允许范围后,需要进行体脂测量的人数减少了20%(从55%[n = 498]降至35%[n = 319])。采用国防部体脂计算公式并未改变超重女性(即不符合AWCP)的比例(从26%[n = 232]变为27%[n = 246])。根据提议的体脂计算公式,更多腰围大于35英寸(即患病风险增加)的女性被认定为不符合AWCP(从76%[n = 61]增至96%[n = 77])。
提议的调整减少了不必要进行体脂测量的女性比例,且未改变AWCP中女性的比例,但挑选出了更多患病风险增加且最需要有效干预的女性。
