[Study on incidences and effect factors of injuries among middle school students in 18 provinces, China].
OBJECTIVE
To identify the current epidemiological situation of injuries among adolescents in China and to provide basis for prevention and control.


METHODS
An anonymous questionnaire survey was conducted among 170 602 middle school students in 18 provinces and cities of China.


RESULTS
The overall incidence of injuries among middle school students was 43.7% while the incidence of recurrent injuries was 20.9%. The incidence of boys was higher than that of girls mainly because of the difference of the recurrent injuries incidence. The incidence of injuries decreased with age in our investigation, especially the recurrent injuries. The main causes of injuries were fall and collision, and the most frequent results of injuries were cut and bone-joint injuries among boys and girls. Key school, nucleic family and higher education level of mothers were protective factors to injuries.


CONCLUSIONS
Adolescents seemed high-risk population for injuries. Some preventive measures should be carried out to decrease the incidence of injuries especially on recurrent injuries.
