Background <p>Little is known about the associations between unintentional injuries from the perspective of parents and their children’s bullying victimization. This study aimed to examine the links between parent-reported unintentional injury subtypes and student-reported experiences of bullying victimization from a school-based large-scale survey.</p> Methods <p>A total of 30,386 students from 35 primary schools, 27 middle schools, and 6 high schools with available data on unintentional injuries, school bullying victimization, and covariates were included in this study. Multivariable and multinomial logistic regression analyses were used to scrutinize the association of 12 types of unintentional injuries with any type of school bullying victimization, as well as multiple types of bullying experienced concurrently.</p> Results <p>10 out of 12 types of unintentional injuries were found to be associated with elevated risks of bullying victimization, with children and adolescents whose parents reported being struck by thrown, projected, or falling objects demonstrating the greatest vulnerability to school bullying victimization, followed by accidental drowning and submersion, contact with sharp instrument, etc. And there was also a positive association between the number of unintentional injuries and bullying victimization. The associations varied among children and adolescents who reported the presence of multiple bullying.</p> Conclusions <p>Certain types and cumulative circumstances of unintentional injuries of children and adolescents necessitate vigilant attention from parents due to the potential indication of bullying. Subsequent research should delve into the underlying mechanisms linking unintentional injuries to school bullying victimization, focusing on specific injury types to provide more targeted guidance for identifying bullying.</p>
