Young teens who are bullied appear to be at higher risk of depression when they reach early adulthood, according to new research.
"We found that teenagers who reported being frequently bullied were twice as likely to be clinically depressed at 18 years," said Lucy Bowes, a researcher at the University of Oxford in England, who led the research.
The researchers found an association, not a definitive cause-and-effect relationship, Bowes said. "In our type of study, we can never be certain that bullying causes depression," she explained. "However, our evidence suggests that this is the case."
To explore the possible link, the investigators used data on nearly 4,000 teens in the Avon Longitudinal Study of Parents and Children, a community-based group born in the United Kingdom. At age 13, all completed a questionnaire about bullying. At 18, they were assessed for depression.
The study found that nearly 700 teens said they had been bullied "often" -- more than once a week -- at age 13. Of those, nearly 15 percent were depressed at age 18. More than 1,440 other teens reported some bullying -- one to three times over a six-month period -- at age 13. Of these, 7 percent were depressed at age 18. In comparison, only 5.5 percent of teens who weren't bullied were depressed at age 18.
Bowes also found the often-bullied teens tended to stay depressed longer than others. For 10 percent of those often-bullied who became depressed, the depression lasted more than two years. By comparison, only 4 percent of the never-bullied group had long-lasting depression.
Among the bullying tactics, name calling was the most common type, experienced by more than one-third of the teens. About one of four had their belongings taken. About 10 percent were hit or beaten up. Most never told a teacher and up to half didn't tell a parent. But up to three-quarters did tell an adult if the bullying was physical, according to the study published in the June 2 online edition of the BMJ.
