The epidemiology of sports injuries in children and youth is an important area of research that has been largely overlooked in the medical and sport science literature. This article presents an overview of the analytic aspects of pediatric sports injury epidemiology, focusing on injury risk factors and preventive measures. The review indicates that few modifiable injury risk factors have been statistically evaluated, and not many studies have been designed to determine the effect of injury prevention measures in pediatric sports. However, initial results are promising. Specific directions for further analytic research are presented.
