Boston, MA (January 5, 2010) For parents wanting to reduce the negative influence of TV on their children, the first step is normally to switch off the television set.
But a new study suggests that might not be enough. It turns out indirect media exposure, i.e., having friends who watch a lot of TV, might be even more damaging to a teenager's body image.
Researchers from Harvard Medical School's Department of Global Health and Social Medicine examined the link between media consumption and eating disorders among adolescent girls in Fiji.
What they found was surprising. The study's subjects did not even need to have a television at home to see raised risk levels of eating disorder symptoms.
In fact, by far the biggest factor for eating disorders was how many of a subject's friends and schoolmates had access to TV. By contrast, researchers found that direct forms of exposure, like personal or parental viewing, did not have an independent impact, when factors like urban location, body shape and other influences were taken into account.
It appeared that changing attitudes within a group that had been exposed to television were a more powerful factor than actually watching the programs themselves. In fact, higher peer media exposure were linked to a 60 percent increase in a girl's odds of having a high level of eating disorder symptoms, independently of her own viewing.
Lead author Anne Becker, vice chair of the Department of Global Health and Social Medicine at Harvard Medical School, said this was the first study to attempt to quantify the role of social networks in spreading the negative consequences of media consumption on eating disorders.
"Our findings suggest that social network exposure is not just a minor influence on eating pathology here, but rather, IS the exposure of concern," she said.
"If you are a parent and you are concerned about limiting cultural exposure, it simply is
