Abstract

The Assessment of Recruit Motivation and Strength (ARMS) project evaluated whether active duty Army enlistees who exceeded weight and body-fat standards but were able to pass the ARMS physical fitness test were at elevated risk of early attrition relative to the traditional recruit population. Attrition among 1146 overweight and overbody-fat (OBF) recruits who passed ARMS was compared to 10,514 fully qualified (FQ) recruits who began service in February 2005 through September 2006. The ARMS test includes a 5-minute step test and a 1-minute pushup test. There were no significant differences in attrition between OBF and FQ at 180 days: adjusted hazard ratios were 1.17 (95% CI: 0.83, 1.65) among females and 1.23 (95% CI: 0.95, 1.58) among males. This study indicates that physically fit recruits who exceeded weight/body-fat standards were equally capable of serving at least 180 days compared to those who met standards.

摘要

新兵动机与体能评估（ARMS）项目评估了那些超过体重和体脂标准但能够通过ARMS体能测试的现役陆军新兵，相对于传统新兵群体，其提前退伍的风险是否更高。将1146名通过ARMS测试的超重和超体脂（OBF）新兵的退伍情况，与2005年2月至2006年9月开始服役的10514名完全合格（FQ）新兵进行了比较。ARMS测试包括一项5分钟的台阶测试和一项1分钟的俯卧撑测试。在180天时，OBF新兵和FQ新兵的退伍情况没有显著差异：女性的调整风险比为1.17（95%置信区间：0.83，1.65），男性为1.23（95%置信区间：0.95，1.58）。这项研究表明，与符合标准的新兵相比，那些超过体重/体脂标准但身体健康的新兵同样能够服役至少180天。
