The public commonly associates steroid use with big-time athletics. But the drugs may be even more of a menace to teenagers. The synthetic hormones can stunt a young person’s growth by prematurely closing the ends of the long bones in the skeleton. That means a 1.7 metre, 15-year-old high school student who uses steroids “might get bigger but won’t get any taller”, according to a US doctor.

Nearly seven percent of boys in the US try steroids before the end of high school, according to a 1988 study by professors Charles Yesalis and William Buckley, of Penn State University. The estimate comes from a poll of 3,400 seniors in 46 public and private schools across the US.

“Abusers of Steroids did it to improve their appearance and to excel at sports,” Professor Yesalis said. “Parents, teachers and coaches make boys believe that to be an ideal male you need to have these. Then they say: ‘you can’t play games to have fun; you play games to win.’”

“Such attitudes put many high school athletes at high risk of becoming abusers of steroids,” said Mike Gimbel, director of Baltimore County Office of substance Abuse. “For these athletes, the pressure to perform is incredible,” he said. “It was inevitable that it would seep down to high school level.”
