ABSTRACT

　Background: Sports-related trauma is an important epidemiological problem. The purpose of this study was to evaluate epidemiological characteristics, and to explore prognostic factors in sports-related trauma in Japan. Methods: A retrospective analysis was performed using the Japan Trauma Data Bank （JTDB） . We included sportsrelated trauma admitted between 2004 and 2018. Logistic regression analysis was performed to explore factors associated with in-hospital mortality and adjusted odds ratios（aOR） were calculated. Results: We identified 5,828 eligible patients, 2,429 were children and 3,399 were adults. The median age was 21 years, and 83.8% were male. The most common season for children was April-June（30.6%） , and the most common season for adults was January-March （37.5%） . In-hospital mortality was 1.2%. In multivariable logistic regression analysis, male, head/neck injury, and thoracic injury were significantly associated with in-hospital mortality （aOR 4.11［95% CI 1.49-17.02］，P=0.018; aOR 18.00［95% CI 10.06-33.92］，P<0.001; aOR 4.18［95% CI2.27-7.50］，P<0.001） . Conclusion: In sports-related trauma in JTDB, male, head/neck injury, and thoracic injury were significantly associated with in-hospital mortality.
