title: Physical illness. A risk factor in anorexia nervosa.
abstract: Reports have appeared in the literature suggesting an association between physical illness and the later development of anorexia nervosa. The histories of 326 patients with anorexia nervosa were examined for physical illness. A higher rate of severe physical illness was found in this group when compared with controls suggesting that it should be regarded as a risk factor for anorexia nervosa. No statistically significant differences were found when illness was examined by time in relation to onset of anorexia, system involved, or when subjects were stratified by age. Possible explanations for the observed association are discussed.
