By Shereen Jegtvig NEW YORK (Reuters Health) – Social media that emphasizes sharing and commenting on photos and other images may feed the anxieties of young women with eating disorders, according to U.S. researchers. In experiments with a group of female college students, those who logged into their Facebook accounts were more likely to worry about their weight and body shape afterward, compared to women who read online articles about a neutral topic. For those working on treatment and prevention of eating disorders, the effects of spending time on Facebook may be a factor to take into account, the study team suggests. “We’ve done research on peer influences in other contexts – this is the first time we’ve looked at social media use,” Pamela Keel told Reuters Health.
