„Children and adolescents who are bullied face higher risks of sleep difficulties, headaches, stomach-aches and other pain; they are also more likely to be overweight or obese. One meta-analysis estimated that children exposed to bullying were about 2.2 times more likely to report such somatic symptoms than their peers. Bullying is also associated with higher risks of substance use, including alcohol, tobacco and illicit drugs. Experiencing bullying is consistently linked with school attendance problems. Whether as an avoidance strategy, or because of increased mental and physical health problems, students who experience bullying tend to miss school more often.“
