  ABSTRACT: This study examined risk factors for self-reported injury incurred before arrival at Ordnance School for advanced individual training (AIT). During AIT in-processing, soldiers (n=27,289 men and 3856 women) completed a questionnaire that collected demographic and lifestyle information, and asked if the soldier currently had an injury that would affect their AIT performance. Potential risk factors for self-reported injury were explored using logistic regression. For men, self-reported injury was associated with older age [odds ratio (OR) >or=30 years/17-19 years=1.9], race (OR Black/Caucasian=1.2), basic combat training (BCT) site (OR Fort Benning/Fort Jackson=1.7; OR Fort Leonard Wood/Fort Jackson=1.6, OR Fort Knox/Fort Jackson=1.3), smoking on 20 or more days in the 30 days prior to BCT (OR smoker/non-smoker=1.2) and current illness (OR ill/not ill=6.2). For women, increased self-reported injury was associated with older age (OR>or=30 years/17-19 years=2.0), BCT site (OR Fort Leonard Wood/Fort Jackson=1.5) and current illness (OR ill/not ill=5.8). Certain demographic characteristics and lifestyle behaviours may be identified as injury risk factors on arrival at Ordnance AIT.

  ABSTRACT: Electronic pedometers were used to quantify locomotor physical activity during an entire 9-week United States Army Basic Combat Training (BCT) cycle. Pedometers were worn on the hips of 4 trainees in each of 10 BCT companies during all BCT activities. Investigators obtained pedometer readings (steps) on a daily basis, and estimated travel distances were obtained by multiplying steps by the average individual step length. A short questionnaire was administered daily to assure trainees wore the pedometers and trained with their companies all day. Trainees performed an average +/- SD of 16 311 +/- 5826 steps/day and traveled an estimated 11.7 +/- 4.4 kilometers/day. The highest daily locomotor activity was during the field training exercise in which trainees took an average +/- SD of 22 372 +/- 12 517 steps/day traveling an estimated 16.2 +/- 9.7 kilometers/day. Differences among the 10 companies ranged from 14 720 +/- 6649 steps/day to 18 729 +/- 6328 steps/day. This survey provided the first examination of locomotor physical activity during an entire BCT cycle.

  ABSTRACT: This study evaluated the influence of a multiple injury control intervention on injury and physical fitness outcomes among soldiers attending United States Army Ordnance School Advanced Individual Training. The study design was quasiexperimental involving a historical control group (n = 2559) that was compared to a multiple intervention group (n = 1283). Interventions in the multiple intervention group included modified physical training, injury education, and a unit based injury surveillance system (UBISS). The management responsible for training independently formed an Injury Control Advisory Committee that examined surveillance reports from the UBISS and recommended changes to training. On arrival at school, individual soldiers completed a demographics and lifestyle questionnaire and took an army physical fitness test (APFT: push-ups, sit-ups, and two mile run). Injuries among soldiers were tracked by a clinic based injury surveillance system that was separate from the UBISS. Soldiers completed a final APFT eight weeks after arrival at school. Cox regression (survival analysis) was used to examine differences in time to the first injury while controlling for group differences in demographics, lifestyle characteristics, and physical fitness. The adjusted relative risk of a time loss injury was 1.5 (95% confidence interval 1.2 to 1.8) times higher in the historical control men and 1.8 (95% confidence interval 1.1 to 2.8) times higher in the historical control women compared with the multiple intervention men and women, respectively. After correcting for the lower initial fitness of the multiple intervention group, there were no significant differences between the multiple intervention and historical control groups in terms of improvements in push-ups, sit-ups, or two mile run performance. This multiple intervention program contributed to a reduction in injuries while improvements in physical fitness were similar to a traditional physical training program previously used at the school.
