Epidemiology of Stress Fracture and Lower Extremity Overuse Injury in Female Recruits
Abstract
Purpose: To examine rates and risk factors for overuse injuries among 824 women during Marine Corps Recruit Depot basic training at Parris Island, SC in 1999. Methods: Data collected included training day exposures (TDEs) baseline performance on a standardized 1,5-mile timed run and a pretraining questionnaire highlighting exercise and health habits. Results: There were 868 injuries for an overall injury rate of 12.6/1000 (TDEs). There were 66 confirmed lower extremity stress fractures among 56 (6.8%) women (1.0/1000 TDEs). Logistic regression modeling indicated that low aerobic fitness (a slower time on the timed run) less than 7 months of lower extremity weight training and no menses for 6 consecutive months during the past year were significantly associated with stress fracture overuse injury. Women who reported fair-poor" baseline fitness were at increased risk for non-stress fracture overuse injury. Conclusions: Stress fractures and other lower extremity overuse injury might be decreased if women entered training with high aerobic fitness and prior participation in lower extremity strength training. Furthermore, women reporting menstrual irregularity and injury during the previous year may require additional evaluation.
