Thirty patients were selected for a prospective study according to two criteria: (i) an irresistible urge to overeat (bulimia nervosa), followed by self-induced vomiting or purging; (ii) a morbid fear of becoming fat. The majority of the patients had a previous history of true or cryptic anorexia nervosa. Self-induced vomiting and purging are secondary devices used by the patients to counteract the effects of overeating and prevent a gain in weight. These devices are dangerous for they are habit-forming and lead to potassium loss and other physical complications. In common with true anorexia nervosa, the patients were determined to keep their weight below a self-imposed threshold. Its level was set below the patient's healthy weight, defined as the weight reached before the onset of the eating disorder. In contrast with true anorexia nervosa, the patients tended to be heavier, more active sexually, and more likely to menstruate regularly and remain fertile. Depressive symptoms were often severe and distressing and led to a high risk of suicide. A theoretical model is described to emphasize the interdependence of the various symptoms and the role of self-perpetuating mechanisms in the maintenance of the disorder. The main aims of treatment are (i) to interrupt the vicious circle of overeating and self-induced vomiting (or purging), (ii) to persuade the patients to accept a higher weight. Prognosis appears less favourable than in uncomplicated anorexia nervosa.

Depressive symptoms may increase in a subgroup of obese individuals shortly after beginning a weight-reducing diet. Therefore an additional antidepressive medication should have a positive effect on the course and results of therapy. This hypothesis was tested in three different institutional settings, with identical therapeutic programs. In this study there were 23 obese women. Therapeutic strategies were concerned with an increase of self-control over eating behavior, the improvement of social skills, and the establishment of new problem-solving abilities. Doxepin was used as the anti-depressant in a double blind procedure. Our results seem to support the hypothesis of this study: depressive symptoms markedly increased soon after the beginning of weight-reduction; additional antidepressive medication helped to improve the symptoms and in the long term had a positive effect on the rate of weight loss.

The authors compared eating patterns, disordered eating, features of eating disorders, and depressive symptoms in persons with binge eating disorder (BED; n = 177), with night eating syndrome (NES; n = 68), and in an overweight comparison group without BED or NES (comparison; n = 45). Participants completed semistructured interviews and several established measures. Depressive symptoms were greater in the BED and NES groups than in the comparison group. NES participants ate fewer meals during the day and more during the night than BED and comparison participants, whereas BED participants ate more during the day than the comparison participants. BED participants reported more objective bulimic and overeating episodes, shape/weight concerns, disinhibition, and hunger than NES and comparison participants, whereas NES participants reported more eating pathology than comparison participants. This evaluation provides strong evidence for the distinctiveness of the BED and NES constructs and highlights their clinical significance.
