The effects of lifetime health damage of bully victims is well documented, but now a recent study finds bullies are healthier long term than their victims.
People who are bullied as children are more prone to depression and suicide when they grow up. They are also more like to get sick, and have stomach troubles and headaches.
A new study may have found the underlying cause: A specific indicator of illness, called C-reactive protein (CRP), is higher than normal in bullying victims, even when they get older. In contrast, the bullies, by the same gauge, seem to be healthier.
The researchers focused on CRP because it’s a common, easily tested marker of inflammation, the runaway immune system activity that’s a feature of many chronic illnesses including cardiovascular disease, diabetes, chronic pain, and depression, explains lead author William Copeland, a psychologist and epidemiologist at Duke University Medical Center in Durham, North Carolina.
To link inflammation to bullying, the researchers asked 1420 youngsters between the ages of 9 and 16 whether, and how often, they had been bullied or had bullied others. Interviewers asked participants whether they felt more teased, bullied, or treated meanly by siblings, friends, and peers than other children—and whether they had upset or hurt other people on purpose, tried to get others in trouble, or forced people to do something by threatening or hurting them. The researchers took finger stick blood tests at each assessment. Interviews took place once a year until the participants turned 16, and again when they were 19 and 21. The children interviewed were participants in the larger Great Smoky Mountains Study, in which some 12,000 children in North Carolina were assessed to track the development of psychiatric conditions.
In the short term, the effect of bullying on the victims was immediate. CRP levels increased along with the number of reported bullying instances, and more than doubled in those who said they’d been bullied three times or more in the previous year, compared with kids who had never been bullied. No change was seen in bullies, or in kids who hadn’t been involved with bullying one way or the other, the researchers report in the Proceedings of the National Academy of Sciences.
