A case-control study on risk factors of injury among rural school-aged children in a county

Objective To explore associated factors for injury in school-age children in rural areas,and to provide evidence for childhood injury prevention.Methods Data was collected by questionnaire survey in 2 196 school-aged children who were recruited from 3 primary schools and 3 junior high schools in rural areas of a county through stratified cluster sampling.Totally 354 children who had been injured were selected as case group.The 1:1 matched in same class,age,gender case-control study was used.Results In the past year,354 children had been injured.The incidence of injury number was 16.12%;375 person-time had been injured.The iucidence of injury pensum-time was 17.08%.The conditional logistic regression showed that the protective factor for injury included non-left-behind experiences(OR=0.467,95%CI=0.248-0.987),while risk factors included undesirable physical condition(OR=1.801,95%CI=1.187-2.733),history of injury(OR=3.161,95%CI=1.611-6.203) and non-only-child(OR=2.071,95%CI=1.413-3.037).Conclusion The incidence of injury in rural school-aged children is relatively high.Self-protection consciousness among children plays an important role in injury prevention.
