Data from the comparisons of injury incidences between males and females, single child and non-single child in the family or among different regions and grades, showed significant differences (P < 0.05). However, no statistical difference was found between students from key or ordinary middle schools (P > 0.05). The results of logistic regression showed that region, grade, gender, having single child or not in the family, tired of staying at school, depression, anxiety, and with peers who often hunt the recreational places were the influencing factors to injury with ORs seen as 1.13, 0.94, 0.72, 0.84, 1.14, 1.47, 1.16, and 2.20, respectively.
