The congressional committee that interrogated Mark McGwire (search) and Jose Canseco (search) will turn its focus Wednesday to steroid use by teenage girls.

The House Committee on Government Reform will hold its fourth hearing on steroids (search) in response to a Centers for Disease Control and Prevention report that anabolic steroid use by young girls is rising. The report indicated that girls not only take steroids to enhance athletic ability, but also to control weight and lose body fat.

Former world champion sprinter Kelli White (search), who tested positive for a performance-enhancing drug at the 2003 World Championships in Paris and was stripped of her gold medals in the 100 and 200 meters, is scheduled to appear at the hearing. The 28-year-old has said she also used banned blood-doping, steroids and testosterone to enhance her performance, without getting caught in drug tests.

Former Olympic and world champion cyclist Mari Holden (search) will also appear at the hearing.
