Among 16- to 22-year-old U.S. males, 7.6 percent report taking various potentially dangerous substances at least monthly to counteract what they regard as an alarming lack of muscularity.
Young men whose insecurities inspire them to use growth hormones, steroids and other body-altering chemicals represent the male counterpart of females whose idealization of thinness prompts them to induce vomiting and otherwise purge their bodies of food, proposes a team led by epidemiologist Alison Field of Boston Children’s Hospital.
Purging and other eating disorders occur mainly in girls and women. Boys and men so obsessed with muscles that they take substances prohibited in competitive sports are more numerous than researchers and clinicians realized, and have been overlooked, Field and her colleagues conclude November 4 in JAMA Pediatrics.
