Incidence, Risk Factors, and Mechanisms of Concussion and Musculoskeletal Injury in Youth Soccer Players

Abstract

Objective: Assessment of incidence, risk factors, and mechanisms of concussion and musculoskeletal (MSK) injuries in youth soccer players over one outdoor season of play. Methods: Prospective cohort study conducted. Participants completed a pre-season baseline questionnaire (demographic and injury history questions). A team safety advocate collected exposure and injury data. Results: A sample of 361 players (10-18 years) participated. Most injuries were reported in games (37 MSK, 24 concussions). MSK and concussions occurred at a rate (/1000player hours) of 5.47 (95%CI:2.99-9.18) and 3.12 (95%CI:0.13-6.16), respectively in males and 5.26 (95%CI: 3.33-7.89) and 3.66 (95%CI: 2.09-5.94), respectively in females. In a univariate model, female sex [IRRmsk=1.18(95% CI:1.02-1.36), IRRconc=1.18(95%CI:1.02-1.36)], previous concussion [IRRconc=1.07(95%CI:1.01-1.15)], higher level of play [IRR: 1.02(Tier II) to 0.63(Tier IV), reference Tier I] and older age group [IRR:1.48(U13) to 1.72(U14), reference U12] were risk factors for MSK injury and/or concussion. Conclusions: Injuries and concussions are common in youth soccer players.
