Incidence, Prevalence, and Burden of Health Problems in Elite Female Ice Hockey Players-A One-Season Prospective...

Introduction: Epidemiological studies on elite female ice hockey players are lacking but needed to tailor preventive efforts in this growing group of athletes. Therefore, the aim of this study was to describe the incidence, prevalence, and burden of health problems in elite female ice hockey players. Methods: In this prospective cohort study, we asked all Swedish Women's Hockey League (SWHL) players (N = 207) to report their health status on the OSTRC-H2 weekly throughout the 2022/2023 season (28 weeks). Reported problems were categorized as injuries (acute or overuse) or illnesses and presented as incidence per player season and mean weekly prevalence. Results: A total of 129 players (62% of all SWHL players) provided 2286 health reports with a mean weekly response rate of 67%. Mean weekly prevalence of health problems was 21% (95% confidence interval [CI]: 19-23) (injuries: 15% [95% CI: 14-17] and illnesses: 6% [95% CI: 5-8]). Injury incidence was 2.1 (95% CI: 1.8-2.4) per player season (acute: 1.2 [95% CI: 1.0-1.5] and overuse: 0.8 [95% CI: 0.7-1.1]). Illness incidence was 1.3 per player season (95% CI: 1.1-1.6). Most reported health problems were acute injuries (59.4% of reported injuries). Most common among acute injuries where to the shoulder (15%), head (13%), and knee (11%). The hip/groin was the most reported (35%) and burdensome (49% of severity score) region among overuse injuries. Reported illnesses were mostly represented by respiratory infections (75%). Conclusions: In average, one in five elite ice hockey players reported a health problem at any given time during the season. Results of this study highlight the need to develop and test primary prevention strategies for shoulder, head, and knee injuries and secondary prevention strategies for hip and groin problems.
