Evidence suggests that female military populations are at greater risk than
their male counterparts for certain training- and combat-related illnesses
and injuries. The objective of this prospective, multisite, epidemiologica
l study was to define the patterns of illness and injury in military women
during training. We developed a computer-based outpatient tracking system f
or prospective data correction of all outpatient encounters for use at (1)
Officer Candidate School (OCS), Quantico; (2) Marine Corps Recruit Depot (M
CRD), Parris Island; and (3) Recruit Training Command (RTC), Great Lakes. D
uring the study period, 85.8% of OCS candidates (260 of 303), 72.4% of MCRD
recruits (2,002 of 2,766), and 83.4% of RTC recruits (7,395 of 8,865) had
at least one medical encounter during training. The most common category of
medical encounters at all three sites was musculoskeletal. injury, followe
d by respiratory and dermatological disorders. This study establishes high
morbidity rates and identifies medical priorities for preventive interventi
ons in Marine Corps and Navy female trainees.
