Both adults and children use anabolic steroids. In one study, use among youth has increased 16% among 10th graders and 37% among seniors in high school since 1996. A 2007 report from the Centers for Disease Control and Prevention found that one of every 25 high school students had used anabolic steroids. The 2009 Pride Survey, of more than 120,000 . students in middle and high school, also looked at steroid use. It found that nearly one in 14 twelfth-grade boys and one in 37 twelfth-grade girls reported using anabolic steroids in the prior year.
