When reading some of the previous post and the chapter in the book concerning eating disorders my interest was sparked. I was interested about if there was if any relationship between eating disorders and twins. Being a twin myself and struggling with self image and growing up considering different eating approaches. Always comparing my twin who was anywhere from 15 to 20 lbs lighter that I am with a very well toned body. Not only did I compare myself to her but also to everyone else. I then did a little research and found some facts. In recent studies involving twins, anorexia was discovered in 9 of 16 identical twins of anorectic patients, but in only one in 14 fraternal twins. http://www.doitnow.org/pages/172.html. The odds of bulimia also increase with genetic similarity. In another study, the rate for identical twins with bulimia was 23 percent (eight times that of the general public), 9 percent in fraternal twins (three times the national average). Just something to think about. I will continue to research this topic, and if anyone finds any other info or have any imputs please share them.
