Abstract
<h3>Background</h3> Understanding the burden of concussion among youth is important to quantify the effectiveness of community-based concussion prevention strategies. <h3>Objective</h3> To determine the lifetime prevalence and one-year incidence of sport-related concussion among male and female high school students (ages 14–19 years) in Alberta, Canada. <h3>Design</h3> Cross-sectional survey. <h3>Setting</h3> High schools (Alberta, Canada). <h3>Participants</h3> High school students (n=2029; 958 male, 1048 female, 23 identified as ‘other’; ages 14–19 years) from 24 schools. <h3>Assessment of Risk Factors</h3> High school students completed a web-based survey during class (October 2018 – March 2019). Students identified the top three sports for participation in the past year. <h3>Main Outcome Measurements</h3> Self-reported lifetime prevalence and one-year incidence of sport-related concussion were described by sex and sport with 95% confidence intervals (CI) adjusted for cluster by school. <h3>Results</h3> Most high school students (1763/2029, 86.69%) reported participating in a sport/recreational activity in the past year. Of the 1,971 students (97.14%) answering the question about lifetime concussion history, 264/923 males [28.60% (95% CI, 21.97–36.31)], 227/1027 females [22.10% (95% CI, 17.96–26.89)], and 3/21 ‘other’ students [14.29% (95% CI, 2.22–55.05)] reported one concussion or more. 131/923 males [14.19% (95% CI, 10.28–19.27)], 99/1027 females [9.64% (95% CI, 7.49–12.33)], and 1/21 ‘other’ students [4.76% (95% CI, 0.46–35.28)] reported at least one concussion in the past year. For males, hockey [32/186, [Incidence Proportion(IP):17.20/100 students/year (95% CI, 12.48–23.23)], lacrosse [4/29, IP: 13.79/100 students/year (95% CI, 5.27–31.52)], and rugby [8/61, IP: 13.11/100 students/year (95% CI, 6.02–26.24)] had the highest rates of concussion. For females, ringette [4/21, IP: 19.05/100 students/year (95% CI, 9.92–33.46)], rugby [9/58, IP: 15.52/100 students/year (95% CI, 8.04–27.84)], and wrestling [3/25, IP: 12.00/100 students/year (95% CI, 3.68–32.76)] had the highest rates. <h3>Conclusions</h3> 1 in 4 high school students report one or more sport-related concussions in their lifetime, and 1 in 9 students reported one or more concussions in the past year. Prevention strategies aimed at reducing concussion burden are crucial.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
