Abstract

The frequency of anabolic steroid use among adolescents is associated with other high-risk behaviors, thus supporting the hypothesis that anabolic steroid use is part of a "risk behavior syndrome" rather than an isolated behavior. This finding emphasizes the need for comprehensive high-risk behavior screening and counseling among teens who use anabolic steroids.
