The study was initiated in 1985. A total of 51 teenagers with anorexia nervosa were studied, together with an equally large control group of healthy persons. The groups have been investigated and compared several times as the years have passed.
"This study is unique in an international perspective. It is the only study in the world that reflects the natural course of anorexia nervosa in the population", says Elisabet Wentz, Associate Professor in Child and Adolescent Psychiatry at the Sahlgrenska Academy.
The research group has published new results from the study in two scientific journals: the British Journal of Psychiatry and the International Journal of Eating Disorders.
Three women have still not recovered from anorexia, 18 years after the start of the study. Thirteen people, or around 25%, are on disability benefit or have been signed off sick for more than six months due to an eating disorder or other psychiatric disorder.. Thirty-nine percent have at least one other psychiatric disorder, in addition to the eating disorder. The most common of these is obsessive compulsive disorder.
