[Psychiatric disorders among parents of patients with anorexia nervosa and bulimia nervosa].

Family diseases represent a risk factor in the multifactorial etiology model regarding the genesis of eating disorders. In German-speaking countries only a few studies give attention to this topic. The aim of this study is to investigate the occurrence frequency of psychiatric disorders and personality styles among parents of juvenile patients with eating disorders. Furthermore a comparison between parents of patients with restrictive anorexia nervosa (AN-R) and parents of patients with bulimia nervosa (BN) is carried out. Psychiatric disorders listed on Axis I and Axis II of DSM-IV (American Psychiatric Association (APA), 1994) and personality styles were assessed in 73 mothers and fathers of 27 patients with AN-R and 13 patients with BN. The results show a high psychiatric strain among parents of patients with AN-R and BN. However the overall psychiatric strain does not differ among the parents of patients with AN-R and BN. Depressive disorders were more frequently observed among mothers of patients with AN-R. Parents of patients with BN showed higher occurrences of paranoid and schizotypal personality styles. A vulnerability of psychiatric disorders is indicated among parents of patients with eating disorders in general but nonspecific for AN-R or BN.
