title: A controlled family study of anorexia nervosa.
abstract: A family study of eating disorders in first and second-degree relatives of anorexia nervosa and nonanorexic psychiatrically ill control probands found increased rates of anorexia-nervosa, bulimia nervosa, and subclinical anorexia nervosa in relatives of anorexic probands. The pattern of familial clustering suggests that these disorders may represent variable expressions of a common underlying psychopathology, although restricter and bulimic subforms of eating disorder may segregate within families. Implications of these findings for understanding factors important to the pathogenesis and subclassification of eating disorders are discussed.
