title: Bulimia nervosa and polycystic ovary syndrome.
abstract: Ninety-four female-female twins underwent a transabdominal ultrasound examination to detect polycystic ovaries. The scans of 52 individuals showed normal ovaries and 42 had evidence of polycystic ovaries. All the subjects were sent a bulimia investigation test (Edinburgh) (BITE) questionnaire for abnormal eating behavior. A total of 74 responses was received (79%). Overall, 76% of women with polycystic ovaries had an abnormal BITE score and their mean BITE score showed a significant increase compared to those with normal ovaries. Also, model fitting analysis suggested a strong genetic effect for bulimia using the BITE scoring system, and it provided strong evidence of a significant influence of environmental factors in the severity score of bulimia.
