Sociodemographic predictors of sport injury in adolescents.
OBJECTIVE
To examine sociodemographic risk factors for sport injury in adolescents.


METHODS
This is a cross-sectional survey design in which a random sample of high school students (ages 14-19) completed an in-class survey (N = 2721). Students were asked questions regarding sociodemographic factors, sport participation, and sport injury in the past year.


RESULTS
The incidence proportion of self-reported and medically treated sports injury, adjusting for the clustering effect of school, was 67.5 (95% CI; 64.2-71.1) and 43.2 (95% CI; 40.4-46.3) per 100 adolescents per year, respectively. Students from small towns had a lower risk of injury than those in the larger urban center (ORadjusted = 0.76, 95% CI 0.63-0.92). Non-Caucasian students had a lower risk of injury than did Caucasian students (ORadjusted = 0.63 (95% CI 0.5-0.79) for all sport injury and 0.57 (95% CI 0.47 - 0.7) for medically treated sport injury. Students with BMI in the 50th-90th percentiles had the greatest risk of sport injury. The risk of injury increased with weekly hours of participation.


CONCLUSIONS
Location of residence, weekly exposure (participation hours), ethnicity, and BMI were simultaneous predictors of sport injuries in adolescents.
