The risk of injury associated with body checking among Pee Wee ice hockey players: an evaluation of Hockey Canadas national body checking policy change
Background In 2013, Hockey Canada introduced an evidence-informed policy change delaying the earliest age of introduction to body checking in ice hockey until Bantam (ages 1314) nationwide.
Objective To determine if the risk of injury, including concussions, changes for Pee Wee (1112 years) ice hockey players in the season following a national policy change disallowing body checking.
Methods In a historical cohort study, Pee Wee players were recruited from teams in all divisions of play in 20112012 prior to the rule change and in 20132014 following the change. Baseline information, injury and exposure data for both cohorts were collected using validated injury surveillance.
Results Pee Wee players were recruited from 59 teams in Calgary, Alberta (n=883) in 20112012 and from 73 teams in 20132014 (n=618). There were 163 game-related injuries (incidence rate (IR)=4.37/1000 game-hours) and 104 concussions (IR=2.79/1000 game-hours) in Alberta prior to the rule change, and 48 injuries (IR=2.16/1000 game-hours) and 25 concussions (IR=1.12/1000 game-hours) after the rule change. Based on multivariable Poisson regression with exposure hours as an offset, the adjusted incidence rate ratio associated with the national policy change disallowing body checking was 0.50 for all game-related injuries (95%?CI 0.33 to 0.75) and 0.36 for concussion specifically (95%CI 0.22 to 0.58).
Conclusions Introduction of the 2013 national body checking policy change disallowing body checking in Pee Wee resulted in a 50% relative reduction in injury rate and a 64% reduction in concussion rate in 11-year-old and 12-year-old hockey players in Alberta.
