Sport participation, sport injury, risk factors and sport safety practices in Calgary and area junior high schools

To examine rates of sport participation, sport injury, risk factors and sport safety practices in young adolescents. Cross-sectional. Calgary and area junior high schools. A random sample of 1466 students (aged 12 to 15 years). Sport injury within one year prior to completing the survey. Ninety-three per cent of students participated in sports in the previous year. The injury rate was 60.85 injuries/100 students/year (95% CI 58.29 to 63.35) for students reporting at least one sport injury, 29.4 injuries/100 students/year (95% CI 27.08 to 31.81) for medically treated injuries, and 12.28 injuries/100 students/year (95% CI 10.64 to 14.07) for injuries presenting to a hospital emergency department. The greatest proportion of injuries occurred in basketball (14%), soccer (12%), hockey (8.6%) and snowboarding/skiing (7.1%). The rates of participation and injury in sports are high in junior high school students. Future research should focus on prevention strategies in sports with high participation and injury rates to have the greatest population health impact.
