The link to the article above is great, it is a long article but full of great information. They compare different outlets of the media, in particular different kinds of magazines and their effects on both girls and boy. What they found was that sports magazines are the least detrimental to the health of girls and boys. They found that between health and fitness magazines and fashion magazines that the health and fitness articles were way worse for girls than fashion and had increased risk for anxiety and self esteem related issues and more importantly they had increased risk of anorexic and bulimic issues. "This one's kind of a no brainer. Girls who compared themselves with magazine images more often also suffered more often from decreased body satisfaction and eating disorders. For boys, the same held true as well, with the extra addition of increased muscularity. This one's also a no brainer. The more the teens thought about the images and compared themselves critically to images they saw in magazines, the more likely they were to have problems with body image and each disorders."
