Application criteria of enteral nutrition in patients with anorexia nervosa: correlation between clinical and psychological data in a "lifesaving" treatment.

Background: Data and research increasingly point to multiple factors in the genesis of eating-behavior disorders, but the lack of a clear etiological definition prevents a unique therapeutic or prognostic approach from being defined. Therapeutic approaches, as well as scientific research, have separately analyzed the psychological aspects and the clinical-nutrition aspects without integrating the variables or correlating clinical and psychological data. This work has several goals because it aims at considering the problem from the 2 different perspectives.
