Physical activity-related injury and body mass index among US high school students

J Phys Act Health. 2007 Jul;4(3):325-42. doi: 10.1123/jpah.4.3.325.


Background: Few studies have focused on the relationship between physical activity-related (PA) injury and overweight among youth.

Methods: We analyzed data from the 2001 and 2003 Youth Risk Behavior Surveys (n = 28,815). Logistic regression was used to examine the independent effects of BMI and frequency of participation in vigorous activity, moderate activity, strengthening exercises, physical education (PE) classes, and team sports on the likelihood of PA injury.

Results: Approximately 14% of females and 19% of males reported seeing a doctor or nurse during the previous 30 d for an injury that happened while exercising or playing sports. PA injury was associated with participation in team sports, strengthening exercises, and (among females) vigorous physical activity. Controlling for type and frequency of physical activity, injury was not associated with being overweight (BMI >or= 95th percentile).

Conclusions: Moderate physical activity and school PE classes may provide relatively low-risk alternatives for overweight youth who need to increase their physical activity.
