London - Almost one in three young men have gone to extremes, such as making themselves sick after eating, in an attempt to look good, researchers say.
New data suggests that eating disorders are a growing problem among teenage boys.
Many are turning to drugs and muscle-building supplements.
The phenomenon is so widespread that the name “manorexia” has been coined to describe it.
The study’s lead author, Alison Field of Boston Children’s Hospital, said: “We need to be thinking more broadly about eating disorders and considering males as well.”
Classical eating disorders include anorexia nervosa, in which a person refuses to eat, and bulimia nervosa, in which someone binges then purges through vomiting or laxative use.
Professor Field said: “For a lot of males, what they’re striving for is different from females. They’re probably engaged in something different from purging.”
Men make up an estimated one in every ten eating disorder sufferers. In the UK, the highest rates of new cases are among girls aged 15 to 19 and boys aged ten to 14.
Bulimia and problems such as binge eating account for 38 percent of new cases, official figures show.
Professor Field’s research on US teenagers found 31 percent of males had binged on food or purged.
Her team spent three years surveying 5 527 boys who were aged 12 to 18 at the start of the study in 1999.
They were asked how they saw their bodies and about unhealthy behaviours such as drug and alcohol use.
Overall young men were most likely to worry about being muscular, and that concern increased with age.
This could be the male equivalent of some girls’ preoccupation with extreme thinness, the study said.
About nine percent reported a high level of concern with muscularity, while two percent had also used some type of supplement, growth hormone or anabolic steroid to look better.
That figure rose to eight percent for older teens aged 16 to 22, the research in journal JAMA Pediatrics found.
Professor Field said using such products was risky: “There are a whole range of products available online that we don’t know if they’re healthy or not. We know when a lot of them are tested, they’re not what they’re marketed to be.”
Young men who used enhancement products were more likely than their peers to binge drink and use drugs.
About six percent of boys were very worried about both having muscle and being thin. Just over two percent worried only about thinness, and this group were the most likely to develop symptoms of depression later on.
Professor Field said “airbrushed” models with unrealistic bodies could have a bad effect on teens.
She said doctors and parents should be aware of attempts by young men to change their bodies, to make sure it is being done for the right reasons and in a healthy way. - Daily Mail
