Anorexics 'more likely to have unplanned pregnancies, abortions'

Posted October 29, 2010

— A new study by the University of North Carolina at Chapel Hill and Norwegian researchers has found that women with anorexia nervosa "are much more likely to have both unplanned pregnancies and induced abortions than women who don’t have the serious eating disorder," the school announced Friday.

The results might be driven by a mistaken belief among women with anorexia that they can’t get pregnant because they are either not having menstrual periods at all or are having irregular periods, according to Cynthia Bulik, the study’s lead author and director of the UNC Eating Disorders Program.

“Anorexia is not a good contraceptive,” Bulik said.

The differences between women with anorexia and women with no eating disorder were striking, according to UNC. The average age of the mothers at delivery was 26.2 years in women with anorexia, compared with 29.9 years in the referent group of women without eating disorders.

Fifty percent of women with anorexia reported unplanned pregnancies, compared with 18.9 percent, while 24.2 percent of women with anorexia reported having induced abortions in the past, compared to 14.6 percent, according to UNC.

Doctors who treat women and adolescent girls, in particular, “need to make sure that they have the conversation about sexuality and contraception as clearly with patients with anorexia as they do with all other girls and women," Bulik said.

In addition, providers who take care of pregnant women need to know when their patients have an eating disorder in order to provide appropriate care. Screening for eating disorders during prenatal visits would be an excellent first step, Bulik said.

In the study, published in the November issue of the journal Obstetrics & Gynecology, Bulik and study co-authors analyzed data collected from 62,060 women as part of the Norwegian Mother and Child Cohort Study. There were 62 women in the sample who reported having anorexia.

Co-authors of the study from UNC are Dr. Elizabeth Hoffman, a PhD student, and biostatistician Ann Von Holle, MS. Co-authors from the Norwegian Institute of Public Health are Leila Torgersen, PhD, Dr. Camilla Stoltenberg; and Dr. Ted Reichborn-Kjennerud.

    Intelligence (or lack thereof) isn't the problem - a mental illness is. Smart people can have mental disorders, which Anorexia is. People with mental disorders in general have more likelihood of a lot of negative things - unplanned pregnancies, drug use, difficulty maintaining employment and relationships, homelessness, you name it.

    Some of the factors that contribute to anorexia are the same factors that may contribute to unplanned pregnancies. A distorted body image and the desire to be accepted would be an example. Intelligence has nothing to do with it.

    Mugu, anorexia is as related to intelligence as cancer, color-blindness, and diabetes. Knowledge and compassion might keep such awful statements from other people's eyes.

    *slaps forehead* this is about as ground-breaking as the article on how exercise and diet benefit obese people.

    What about the fact that anorexics aren't very smart and that causes pregnancies.
