20
Q

What Causes Eating Disorders? (part 1)

A
  • Most theorists and researchers use a multidimensional risk perspective
  • Several key factors place individuals at risk
  • More factors = greater likelihood of developing a disorder
  • Leading factors
  • Psychodynamic
  • Cognitive-behavioral
  • Biological
  • Societalpressures
  • Family environment
  • Multicultural
21
Q

• Psychodynamic factors:

A

ego deficiencies

  • Bruch: Psychodynamic theory of eating disorders
  • Disturbed mother–child interactions lead to serious child ego deficiencies and severe perceptual disturbances
  • Children of ineffective parents(fail to attend child needs) become confused adults who are unaware of their internal needs
  • People with eating disorders inaccurately perceive internal cues (alexithymic) and are more likely to worry about how they are viewed by others
22
Q

• Cognitive-behavioral factors

A

• Bruch: Several cognitive factors, such as improper labeling of
internal sensations and needs, contribute to eating disorders
• Little control over life may result in excess control of body size
• This contributes to a broad cognitive distortion that lies at the center of disordered eating—for example, negative self- judgment based on body shape and weight

23
Q

• Depression

A
  • Helps set the stage for eating disorders
  • Many more people with eating disorders are diagnosed with major depressive disorders than in the normal population
  • Close relatives with eating disorders have higher rates of depressive disorders
  • Similar brain circuit abnormalities in those with eating disorders and depression
  • Antidepressant drugs sometimes help persons with eating disorders
24
Q

• Biological factors

A
  • Certain genes may cause susceptibility to eating disorders
  • Relatives of people with eating disorders are six times more likely to develop eating disorders themselves
  • Brain circuit dysfunction linked to interconnectivity problems
  • Larger and more active insula, orbitofrontal cortex, and striatum; smaller prefrontal cortex
  • Abnormal activity levels of serotonin, dopamine, and glutamate
25
Q

other biological factors

A
  • Other biological theorists focus on the hypothalamus
  • Lateral hypothalamus(LH):Produces hunger
  • Ventromedial hypothalamus(VMH):Reduces hunger
  • Weight set point
  • Set by genetic inheritance and early eating practices
  • Responsible for keeping an individual at a particular weight level
26
Q

• Societal pressures

A
  • Western standards for female attractiveness
  • Socially accepted prejudice against overweight people
  • Higher risks for eating disorders within certain subcultures (e.g., models, actors, dancers, and certain athletes)
  • Economic and racial differences in eating disorders prevalence rates
  • Social networking, Internet activity, and television browsing
27
Q

• Family environment

A
  • Families may impact and maintain eating disorders

Q

-Multicultural factors: Gender Differences

A

• Males account for only 10 percent of all cases of eating
disorders
