Survival rates of anorexia sufferers, non-sufferers differ little

A long-term study of patients in Rochester, Minn., with the eating disorder anorexia nervosa found that their survival rates did not differ from the expected survival rates of others of the same age and sex. The results, published in the March issue of Mayo Clinic Proceedings, add to the knowledge of anorexia nervosa and point to other areas that need greater study from researchers. “Although our data suggest that overall mortality is not increased among community patients with anorexia nervosa in general, these findings should not lead to complacency in clinical practice because deaths do occur,” says L. Joseph Melton, III, M.D., Mayo Clinic epidemiologist and an author of the report.

Researchers find genetic link to bulimia nervosa

A team of researchers has linked an area of chromosome 10p to families with a history of bulimia nervosa, providing strong evidence that genes play a determining role in who is susceptible to developing the eating disorder. The finding, gleaned from blood studies of 316 patients with bulimia and their family members, is the result of the first multinational collaborative genome-wide linkage scan to look exclusively at bulimia. Earlier this year, another linkage scan found evidence of genes for the eating disorder anorexia nervosa on chromosome 1.
