Effectiveness evaluation of comprehensive intervention about injury among the left-behind children in rural area of Enshi

Objective To explore the effectiveness of comprehensive intervention about injury and provide evidence for eliminating injury among the left-behind children in rural area. Methods Left-behind children were recruited from grades 3-5 in 3 primary schools and grades 7-8 in 3 secondary schools of rural Enshi by stratified and cluster sampling and randomly divided into an intervention group and a control group by school. The intervention group was given comprehensive intervention for 1 year, while the control group without any interventions. Before and after the intervention, a questionnaire survey was conducted among the two groups. Results After 1 year, the score of injury knowledge in the intervention group (11.53±1.56) were higher than that of the control group (11.07±2.30), respectively(t=3.540,P<0.001). The score of unsafe behavior in the intervention group (2.64±1.79)were lower than that of the control group (3.48± 1.78), respectively(t=7.070,P<0.001). Awareness rates about 11 indicators of the intervention group were higher and incidence rates about 2 unsafe behaviors of the intervention group were lower than before intervention, and all the differences were statistically significant(all P<0.05). The incidence rate of injury in the intervention group decreased from 23.53% to 11.69% and the difference was statistically significant(χ²=23.127,P<0.001). Conclusions Comprehensive intervention can reduce the incidence rate of injury, which is an effective measure for injury control among the left-behind children.
