The purpose of this study was to conduct a meta-analysis to determine the prevalence of developmental disorders in children with school refusal using systematic reviews. According to the inclusion criteria, 18 reports were selected. A meta-analysis of the collected data was performed using the Metaprop package in the R3.2.2 software program. The pooled rates were calculated using the Freeman-Tukey double arcsine transformation method. The total populations from these reports were 3,196 and 438 for school refusal in children and children with developmental disorders, respectively. The pooled prevalence of developmental disorders in children with school refusal was 13.70% (95%CI: 12.0%-27.0%). In the subgroup analysis, children who were admitted to a medical institution for school refusal had a 25% possibility of a developmental disorders (95%CI: 17.0%-36.0%). Our findings demonstrate that the prevalence of developmental disorders in children with school refusal in Japan remains high.
