Traumatic brain injury in high school athletes

Area of Science:

• Sports Medicine
• Neurology
• Public Health

Background:

• Mild traumatic brain injury (MTBI) is a growing concern, yet data on its prevalence in high school athletes remain scarce.
• Understanding MTBI frequency is crucial for developing targeted prevention strategies in adolescent sports.

Purpose of the Study:

• To determine the incidence, types, and severity of mild traumatic brain injuries (MTBIs) across various high school sports.
• To provide an estimate of the national incidence of MTBI among high school varsity athletes.

Main Methods:

• An observational cohort study was conducted involving 246 certified athletic trainers across 235 US high schools.
• Injury and exposure data were collected for varsity athletes in 10 sports (football, wrestling, baseball, field hockey, volleyball, softball, basketball, soccer) over three academic years (1995-1997).
• MTBI was defined as a head-injured player removed from play and evaluated by a medical professional before returning.

Main Results:

• Out of 23,566 total injuries, 1,219 (5.5%) were classified as MTBIs.
• Football had the highest number of MTBI cases (63.4%), followed by wrestling (10.5%) and girls' soccer (6.2%).
• An estimated 62,816 MTBI cases occur annually in these sports, with football accounting for approximately 63%.

Conclusions:

• MTBI rates differ significantly among high school sports, with no studied sport being entirely free of these injuries.
• The findings underscore the necessity for ongoing collaboration among stakeholders to mitigate MTBI risks in high school athletics.
