Bullying among school-aged youth is a common issue worldwide and is increasingly being recognized as
an important problem affecting both victims and perpetrators. Most of the bullying studies have been
conducted in western countries, and their implications in other regions are limited due to different
cultural contexts. The goal of our study is to identify the prevalence of bullying and its correlates schoolaged
youth in Guangdong province. In total, 1098 (7.1%) students reported having bullied other students,
744 (4.8%) students reported having been bullied by other students and 396 (2.6%) students reported
having both bullied other students and been bullied by other students. There was a strong association
between bullying others as well as being bullied and suicidal ideations, suicidal attempts, and self-harm
behaviors. The prevalence of bullying and its associations with delinquent behaviors warrant the
importance of school facility based preventive intervention taking into account both victims and
perpetrators.
