Methods: The literatures on the incidence of unintentional injury in children included in China from 2008 to 2018 were analyzed by meta-analysis method. The data were retrieved according to the guidance of Cochrane Systematic review. A meta-analysis was carried out on homogeneous studies, and then subgroup analysis was conducted according to age group. Publication bias was also evaluated.

Results: A total of 3,303 related pieces of literature were reviewed. Of the 37 that met the inclusion criteria. The meta-analysis showed that total sample sizes were 77,023, and the pooled incidence of unintentional injury is 20%, 95%CI (17%-23%), (P< 0.001). Subgroup analysis showed the following results: the incidence are 15%, 23%, 20% and 20% for aged in 0-2, “3-5”, “6-11”, “12-18subgroups, respectively. However, the trend of decreased incidence of unintentional injury with older age in children was not significant.
