Diagnostic Criteria Genes -> Cells -> Systems -> Behaviors 0. Genes 0. Code for mRNAs -> code for proteins w/i cells 1. Altered systems in the brain: 1. Altered brain activation as seen by MRI 2. Altered behavior: 2. Outward expression Nature vs. Nurture 3. EDOs run is families 4. Twin studies demonstrate significant genetic factors 5. Nurture: 3. Sociocultural factors: pursuit of unrealistic thinness ideal, promotion of body dissatisfaction that precedes DO 4. All people exposed but only some develop EDOs Gene-Environment interaction 6. Same people who give us our genes also create our environment 5. Ex: IQ = “double advantage” 6. Pass down genes & model disordered eating/attitudes = “double disadvantage” 7. Genes may drive us to seek out environments that emphasize appearance and thinness 7. Ballet or gymnastics: culture of thinness combined with genetic predisposition Gene X Environment 8.
