Weight Status and School Bullying Experiences in Urban China: The Difference Between Boys and Girls

Abstract

This article examined the associations between weight status (body mass index [BMI] and perceived weight measures) and school bullying experiences (being bullied and bullying others) of children and adolescents in urban China. A national representative sample (n = 3,675) of all types of pre-college schools from seven Chinese cities was employed for the analysis. Students from all grades in high school, vocational school, middle school, and primary grades 4 to 6 were surveyed. Height, weight, perceived weight status, and experiences of being bullied and bullying others were obtained. The results demonstrated that the objective weight status (BMI) was neither associated with being bullied overall by others nor associated with bullying others, but the subjective/perceived weight status was significantly related to being bullied. Regarding the specific forms of being bullied, underweight (measured by BMI) students were less likely to be cyberbullied, whereas obese (measured by BMI) students were more likely to be cyberbullied. Students who perceived themselves as slightly fat and too fat were more likely to be verbally bullied. Overweight and obese students were more likely to bully others physically and relationally, and the students who perceived themselves as too thin were positively associated with physically bullying others. Moreover, BMI had a role in the involvement in school bullying for boys, whereas perceived weight status had a role in school bullying involvement in girls. These results indicate that school bullying prevention and intervention should consider weight status, as well as gender differences.
