    Association between sports participation history and age of first exposure to high-risk sports with concussion history
    (Taylor & Francis, 2023) Caccese, Jaclyn; Schmidt, Julianne; Moody, Jena; Broglio, Steven; McAllister, Thomas; McCrea, Michael; Pasquina, Paul; Buckley, Thomas; CARE Consortium Investigators; Psychiatry, School of Medicine
    The purpose of this study was to examine the association between sports participation history, including estimated age of first exposure (eAFE) to high-risk sports, and concussion history in first year (i.e., freshmen) collegiate athletes. Athletes increased their odds of sustaining a pre-college concussion by 5% [odds ratio(OR) = 1.05 (95%CI:1.05-1.06)] for each additional year of contact sports participation - 24% of all student athletes reported one or more pre-college concussions. When eAFE was analysed dichotomously at age 12, a greater proportion of those who started playing football before age 12 reported a positive concussion history compared to those who started playing football at age 12 or later (Х2 = 4.483, p = 0.034, Phi = 0.049). When eAFE was analysed continuously, later eAFE to women's high-risk sports was associated with a lower likelihood of sustaining a pre-college concussion [OR = 0.93 (95%CI:0.88-0.98)]. Our findings suggest that there is a relationship between eAFE to football and to women's high-risk sports and concussion history.

    Mechanisms of injury for concussions in collegiate soccer: an NCAA/DoD CARE consortium study
    (Taylor & Francis, 2022) Kaminski, Thomas W.; Chrismanh, Sara P. D.; Glutting, Joseph; Wahlquist, Victoria; Eagle, Shawn; Putukian, Margot; Tierney, Ryan; Broglio, Steven P.; McAllister, Thomas W.; McCrea, Michael A.; Pasquina, Paul F.; Kontos, Anthony P.; CARE Site Investigators; Psychology, School of Science
    Objective: The purpose of this study was to describe the mechanism of injury (MOI) and examine factors associated with greater risk for specific MOIs involving concussions in collegiate soccer players. Methods: Participants included 3,288 collegiate soccer players from 28 institutions across four competitive seasons, 2014-17. MOIs were documented for 262 soccer-related concussions during the study and placed into one of four categories: collisions, unintentional contact, aerial challenges, and others. Results: 70% of the concussions occurred in DI soccer players. Collisions and unintentional contact were the MOIs that resulted in 66.5% of all concussions. DI and DIII soccer players sustained more concussions by unintentional contact versus collisions and aerial challenges when compared to their DII counterparts. Defenders were more likely than midfielders to sustain concussions by aerial challenges than collisions. As expected, the field players experienced more concussions as a result of collisions, unintentional contact, and aerial challenges when compared to goalkeepers. Conclusions: Future research should explore preventive strategies for decreasing collisions, especially during aerial challenges while heading the soccer ball, and unintentional contacts from errant balls in soccer in order to decrease concussion risk.
