Methods: Data were obtained from 204 female patients with AN, divided into two groups based on illness duration: short-term illness duration (less than 5 years; = 118); and long-term duration (5 years or more; = 86). Physical parameters were measured using blood serum testing and psychological aspects were assessed using various instruments.
