NOTE, anorexia ‘beats’ bulemia, as in, if a person meets the crtieria for BOTH bulemia and AN, they’ll get diagnosed with AN binge-eating subtype

Question 10

What is the crtieria for a binge eating episode in the context of BN and BED

Answer 10

Eating, in a discrete period of time(e.g., within a two-hour period), an amount of food that is definitely largerthan what most people would eat during a similar period of timeand under similar circumstances
–Lack of control over eatingduring the episode (e.g., a feeling that you cannot stop eating, or control what or how much you are eating)

Question 15

Social explanations of EDS

Answer 15

Media and cultural, body standards.

Question 16

EDs and Dieting

Answer 16

Deitary; adolescent dieting linked to 6-18x greater risk of developing an ED. We tend to become obsessed with food when we can’t eat much (that fucked study about when participants were put on a restrictive diet, they started obsessing over food)

Question 17

Family influence of EDS

Answer 17

Parents with distorted perception of food and eating may restrict children’s intake too
•Families of individuals with anorexia are often:

•Disordered eating also strains family relationships

AN usually comes from close boundary crossing families
BN comes from chaotic and conflicted families

Question 18

Biological links to Eds

Answer 18

Not much? There is a genetic element (more likely to get one if parent has one)
