High school data originated from the HS RIO surveillance data, 2005–2006 through 2013–2014; collegiate data originated from the NCAA-ISP surveillance data, 2004–2005 through 2013–2014. Injuries included in the analysis were those that (1) occurred during a sanctioned practice or competition; (2) were evaluated or treated (or both) by an athletic trainer, physician, or other health care professional; and (3) restricted the student-athlete from participation for at least 24 hours past the day of injury. All concussions, fractures, and dental injuries were included in the analysis regardless of time loss. The data may include multiple injuries that occurred at 1 injury event. Excluded were 2 injuries reported in HS RIO because of missing data for body part. Percentages may not add to 100.0 because of rounding error.
