Introduction: Injuries among children and adolescents remain a major public health problem in China. In the present study, we undertook a systematic review and meta-analysis of the published literature of epidemiological studies investigating injuries among children and adolescents in China and aimed to describe the status of injury among children and adolescents (aged 0-19 years) in China nationwide. A random-effects meta-analysis model was used to calculate the pooled prevalence of injury with 95% confidence intervals (CIs) across studies. The potential heterogeneity moderators were identified by subgroup and sensitivity analysis. A total of 775,615 children and adolescents were included in this study. Overall, the pooled injury prevalence among children and adolescents aged 0 to 19 years was 23.0% (95% CI 20.0%-27.0%) in studies using 1996 version of injury definition, and 13.0% (95% CI 10.0%-17.0%) in studies using 2004 version of injury definition. Relevant heterogeneity moderators have been identified by subgroup analysis. Sensitivity analysis yielded consistent results.
Conclusion: Our study shows a moderately high injury prevalence among children and adolescents aged 0 to 19 years in China, more prevention policies and programs should be urgently developed to decrease the occurrence of child and adolescent injury.
