Dr. Kaye et al. suggested that "childhood anxiety represents one important genetically mediated pathway toward the development of anorexia nervosa" (p. 2215) and that this is reflected in onset of OCD before anorexia. Dr. Kaye et al. reported that of 94 patients with anorexia nervosa, 35% also had OCD. Upon examination of these, about 12% dropped out, and of those remaining, 23% had OCD before they had anorexia nervosa. Thus, 94×35%×88%×23%= seven individuals of 94 (7%) had OCD before they had anorexia nervosa. A French study on the same topic (1) reported that two (7%) of 29 patients had OCD before they had anorexia nervosa. Thus, the expression of OCD before anorexia nervosa is rare.
