Incidence and aetiology of head injury in a New Zealand adolescent sample.

This study reports the major aetiological factors and incidence rates of head injury in an adolescent sample, and compares them with previous research in New Zealand and overseas. Subjects had come to medical attention, but also included were those who had sustained a head injury but had not sought medical attention. An overall incidence rate of almost 14% was reported, with the major cause of head injury in male students being sport, and collisions in the females.
