A study finds college women who live in sororities may be at higher risk for developing eating disorders.The study finds live-in sorority members were more likely than women living off-campus and in dorms to avoid high-fat foods and they were more likely to use diet pills. They also say their weight concerns interfered more with their social relationships. Wendy Macke, a registered dietician at the Iowa Heart Center, says sorority women may feel more of a need to conform because they belong to a group of women with shared interests.The Michigan State University study found about 13-percent of sorority women were “at risk” for developing eating disorders, compared to ten-percent of dorm women. It also found about 11-percent of all women were at risk for eating disorders as are four-percent of all men. Macke says there are lessons in the study from which everyone can learn.Macke recommends everyone try to eat balanced meals and exercise regularly, for about 30-minutes a day, three-to-four days a week.
