Use of Noninvasive Bone Structural Measurements to Evaluate Stress Fracture Susceptibility Among Female Recruits in U.S. Marine Corps Basic Training: Individual Profiles of Stress Fracture Susceptibility Among Female Recruits in U.S. Marine Corps Basic Training
Abstract
The objective of this study was to derive predictive models of stress fracture susceptibility in female military recruits by administering a questionnaire highlighting exercise and health habits prior to reporting to Marine Corps Recruit Depot (MCRD), Parris Island, and assess body composition and anthropometric measures immediately after reporting to MCRD, Parris Island. A second objective of this study was to establish enrollment procedures and begin enrolling subjects for a second phase of the study which will add femoral and tibial dual energy x-ray absorptiometry (DEXA) scans for each subject. The study population consisted of 1,054 (90%) of the 1,165 female recruits reporting to MCRD, Parris Island; 613 had anthropometric measures; 175 subjects had femoral and tibial DEXA scans. Fifty-two recruits (4.9% of the population) had 56 stress fractures. The most common sites were: metatarsal (n=19; 34%); pelvis (n=18; 32%); tibia (n=11; 20%); and femur (n=8; 14%). Previous injury history, fitness as measured by the 0.75 mile run, and late age at first menses were significantly associated with a higher incidence of stress fracture. Smoking cigarettes or alcohol use during the 6 months before reporting to MCRD were not significantly associated with stress fracture. Subjects will be continued to be enrolled using DEXA scanning and these results will be reports under another follow-on work unit. It is anticipated that these results will guide the design and implementation of preventive interventions.
