title: Behavior, attitude, nutrition and endocrinology in anorexia nervosa.
abstract: Twenty-four anorexia nervosa patients participated in an inpatient broad spectrum behavior therapy program. The changes in body weight, anorectic behaviors and attitudes and endocrine variables (24-h plasma cortisol, dexamethasone suppression test, 24-h plasma luteinizing hormone) were measured. Data indicate that specific anorectic behaviors and attitudes showed significant improvement during inpatient treatment, while attitudes of a more general neurotic scope such as the feeling of insufficiency, general distress, (sexual) anxieties and anancasm did not. On admission 24-h plasma cortisol levels were elevated, episodic secretory spikes occurred at unusual times and the number was increased, cortisol plasma half-life was increased and non-suppression of cortisol secretion following the application of dexamethasone was observed. All these parameters normalized already after 10% weight gain. 24-h plasma LH pattern showed a close relationship with body weight. Our data suggest that the dysfunctions in anorexia nervosa patients in the hypothalamo-pituitary-adrenal and -gonadal axis have little specificity for this disease and are mainly a consequence of nutritional factors and starvation. The relationship between cortisol and HL-secretion, behavioral and attitudinal variables and weight gain was more complex than previously suggested by others and a positive relationship between the LH secretory pattern and anorectic symptomatology could be established.
