Injury Incidence and Injury Risk Factors Among U.S. Army Basic Trainees at Ft. Jackson SC, 1998 (Including Fitness Training Unit Personnel, Discharges, and Newstarts)

摘要

An epidemiological consultation (EPICON) was requested by the Commander, U.S. Army Training Center, Ft Jackson, SC, to assist in the development of an Army Center for the Study of Training-Related Injuries. This EPICON (1) compared injury rates with a previous investigation, (2) examined injuries in special Basic Combat Training (BCT) subgroups, and (3) explored injury risk factors. Cumulative incidence of one or more injuries in the present study (men and women, respectively), was 37% and 63%, much higher than the 15% and 38% found previously at Ft Jackson in the fall of 1997. Men coming from the Fitness Training Unit (FTU) were more likely to get injured (57% vs 36%, p=0.01) and less likely to graduate (55% vs 82%, p <0.01), compared to men who went directly to BCT. On the other hand, women coming from the FTU had similar injury incidence (62% vs 63%, p=O.78) and first-time graduation success (60% vs 68%, p=O. 14) compared to women who directly entered BCT. Men who were discharged were more likely to be injured than those who were not discharged (p <0.01) while female discharges were equally likely to be injured compared to women who were not discharged (p=0.38). Injury incidence was high among the newstart-outs (recycles), 65 % for men and 97% for women, primarily accounted for by individuals sent to the Physical Training and Rehabilitation Program (PTRP) for injury recovery. Risk factors for time-loss injuries (i.e., injuries with one or more days of limited duty) among the men included training company; older age; lower performance on diagnostic push-ups, sit-ups, or the 2-mile run; cigarette smoking prior to BCT; no prior sports participation; less walking or hiking in the last month; lower peak VO2; low upper body static strength; and lower or higher levels of hamstring flexibility. Risk factors for time-loss injuries among women included training company; low performance on the diagnostic push- ups, sit-ups, or the 2-mile run.
