Yes: Biologic, but not necessarily genetic. Women are more likely to have eating disorders than men, especially anorexia nervosa. In twins generally, if one has it the other has a higher chance of having it. That could be more sociological than genetic, especially when raised together. Sisters have a higher rate for that reason. Major mood disorders are higher in these families. Sexual abuse is common.
