Screening and early interventions to address loneliness, sleep disturbances, and alcohol consumption can help to reduce the association between bullying at school and suicidal behaviors, a new study has found.
Researchers from The University of Queensland’s Life Course Centre examined the relationship between bullying victimization and suicidal behaviors in more than 280,000 teenagers aged 13-17 in 90 countries worldwide. Lead author Ph.D. candidate Md. Mehedi Hasan said children who had been bullied had higher rates of suicidal ideation, planning, and attempts:

“Bullying victimisation and associated adolescent suicide behaviours are a major global health issue, with substantial detrimental ‘ripple effects’ on friends, families and communities. We found that 32.4 percent of adolescents had been bullied, while 12.1 per cent reported suicidal ideation, 11.1 percent suicidal planning, and 10.9 per cent a suicide attempt.
“For the first time, our study sheds light on key factors involved in the relationship between school bullying victimisation and adolescent suicidal ideation, suicidal planning and suicide attempts.”
Teenagers who were bullied were at an increased risk of physical inactivity, soft drink and fast food consumption, absenteeism from school, smoking, alcohol consumption, peer victimization and conflict, hunger, sleep disturbance, loneliness, lack of peer support, and less parental supervision and connectedness.
Strong links between bullying and suicidal behaviors
Co-author Associate Professor Abdullah Mamun said the strongest links between adolescent bullying and suicidal behaviors were loneliness, sleep disturbances, and alcohol consumption:
“There was a ‘feedback loop’ between loneliness and bullying victimisation, with students experiencing one of these risks also more likely to experience the other. Sleep disturbances and alcohol consumption can also feed into this cycle.
“To address suicidal behaviours through school-based bullying prevention initiatives, there is a need to screen adolescents for these factors and design policies and programs that promote social engagement, good sleep health and less alcohol consumption.”
Dr. Mamun said social connectedness and peer relationships were crucial to adolescent development, health, and well-being:
“The findings of this study are particularly timely given the events of COVID-19, where social distancing measures, school closures, and stay-at-home orders may have exacerbated feelings of loneliness in adolescents. The pandemic may have also increased adolescents’ exposure to cyberbullying through more time spent online.
“In light of this, it is important for adolescent bullying prevention and suicide strategies to carefully consider the important role of peer connection in informing and designing targeted interventions.”
