An Eastern Michigan University expert thinks he knows the main explanation for new study results that show that gay and bisexual teenage boys use steroids at a rate almost six times higher than do straight kids. The study out of Chicago says that 21 percent of gay or bi male teens claimed they have used steroids, compared with four percent of straight boys. Michael Tew is the Director of the Center for the Study of Equality and Human Rights at Eastern Michigan University. He says the steroids are used to attain an ideal masculine body image. Tew says media portrayals of "real" people rather than a bulked up "ideal" could help change the trend. More importantly, he says parents should be aware of their child's body image.
