Experts say the problem calls for more research and preventive measures.
Most studies on bullying have been done in Europe and Australia. But a new survey, published in the April 25 issue of the Journal of the American Medical Association , examined the frequency of youth bullying in the US, and figured out the association between bullying and being bullied, and its psychosocial effects. Researchers also looked at the incidence of bullying by gender and age. In this study, researchers analyzed data from a nationally representative sample of more than 15,000 students in grades 6 through 10 in both public and private schools. Researchers found that boys were more likely than girls to be both bullies and targets of bullying.
