[Meta analysis for interventional effect on unexpected injury among children and adolescents in China].
OBJECTIVE
To comprehensively evaluate the interventional effect on unexpected injury among children and adolescents in China, and to provide scientific basis for the injury control strategy.


METHODS
Meta analysis was utilized to analyze the selected literatures. After heterogeneity test of the data, a relevant model was chosen to estimate the combined effect values relative risk (RR) and the corresponding 95% confidence interval (95% CI). Subgroup analysis were performed based on the intervention measures, objects and places. Sensitivity and publication bias were analyzed.


RESULTS
A total of 18 papers were included in the Meta analysis with a sample size of 32 599. The combined RR value was 0.54 (95% CI 0.44 to 0.68). Subgroup analysis showed that the RR value of health education and comprehensive intervention were 0.59 and 0.50, respectively, with no significant difference between them (P>0.05). The RR values of the interventions in school alone, in school and community or in community alone were 0.51, 0.78 or 0.63. The RR values on children alone, children and parents or parents alone were 0.53, 0.65 or 0.35. The differences were significant when the interventions were performed among different places or objects (P<0.05). Sensitivity analysis revealed that meta-analysis results were relatively stable.


CONCLUSIONS
The targeted interventions were significant in the prevention of unexpected injuries among children and adolescents. It is worth further promoting and spreading.
