Abstract : The objective of this prospective cohort study is to develop predictive models for stress fractures and other overuse musculoskeletal injuries seen in female military trainees. Subjects are USMC female recruits reporting to MCRD, Parris Island, for boot camp. Prior to training, all subjects complete a baseline questionnaire addressing exercise and lifestyle history. A subset of subjects has anthropometric measurements and bone structural analysis performed using a dual energy x-ray absorptiometry (DEXA) scanner, a noninvasive commercial bone mineral scanning system. Recruits are followed prospectively through 13 weeks of basic training. Injuries are documented by medical review and an on-site outpatient computer tracking system. Progress includes: human use approval; hiring and training of on-site staff; and development of questionnaire, measurement, and DEXA procedures. Since March 1995, 800 of the 894 female recruits reporting to MCRD, Parris Island, have been enrolled Following installation of the DEXA scanner in June 1995, the last 100 subjects also had scans. At the current enrollment rate, the required sample size of subjects will be realized by third quarter FY96. It is anticipated that study results will guide the design and implementation of preventive interventions to reduce the occurrence and cost of injuries and attrition in female Marine recruits.
