Gay, bisexual teens at risk for eating disorders

By Amy Norton

NEW YORK (Reuters Health) - Gay, lesbian and bisexual teenagers may be at higher risk of binge-eating and purging than their heterosexual peers, starting as early as age 12, a new study finds.

Past research has found connections between sexual orientation and the risk of eating disorders in adults -- showing, for instance, that gay men have higher rates of symptoms than their heterosexual counterparts.

Less has been known about how sexual orientation affects teenagers' risks of various eating disorders.

For the new study, researchers at Harvard University and Children's Hospital Boston used data from a U.S. survey of nearly 14,000 12- to 23-year-olds to look at the relationship between sexual orientation and binge-eating and purging.

They found heightened rates of binge-eating among both males and females who identified themselves as gay, lesbian, bisexual or "mostly heterosexual."

Purging, by vomiting or abusing laxatives, was also more common among these teens, the researchers report in the Journal of Adolescent Health.

"We found clear and concerning signs of higher rates of eating disorder symptoms in sexual-minority youth compared to their heterosexual peers even at ages as young as 12, 13 or 14 years old," lead researcher S. Bryn Austin, an assistant professor of pediatrics, told Reuters Health in an email.

Among females, lesbian, bisexual and mostly heterosexual respondents were all about twice as likely as their heterosexual counterparts to report binge-eating at least once per month in the past year.
