Chapter 7 Outline Eating disorders: Anorexia Nervosa (AN) *Eating disorders have been and continue to be a popular topic for debate, discussion, and research. However, a variety of causes, theories, and treatment options surround this quite common disorder, especially for females. Anorexia Nervosa: 1. Definition of Anorexia Nervosa a. A serious condition marked by an inability to maintain a normal healthy body weight. b. Extremely visible disorder where people are noticeably thin to the point of emaciation (e.g., severe underweight) c. Body mass index (BMI) i. Measured by weight in kilograms, divided by height in meters squared ii. An individual with Anorexia Nervosa may weight 85% less than her ideal body weight iii. Psychologists and other mental health professionals use this calculation to measure thinness d. Two subtypes: i. Restricting (e.g., the reduction of caloric intake paired with excessive exercise or physical activity) ii. Binge eating/purging (e.g., eating a large amount of food in a short period of time; self induced vomiting, or use of laxatives, enemas, or diuretics) e. DSM-IV-TR: Clinical features i. Intense fear of gaining weight, “feeling fat” ii. Perceptual distortion (e.g., perceiving bodies as overweight or obese when actually emaciated) iii. Emphasis on body shape and weight as a means to measure one’s self worth (e.g., self evaluation) iv. Deny the seriousness of being drastically underweight v. Amenorrhea (absence of menstruation for at least three consecutive months) 2. Epidemiology and Course of Anorexia Nervosa a. Clinical features associated with Anorexia Nervosa (e.g., see Table 7.3) b. Prevalence rates: i. 0.3% to 1% suffer from Anorexia Nervosa (e.g., meaning 1 in 100 females) ii. Many females suffer from a less severe form of Anorexia Nervosa (e.g., threshold conditions, 1% to 3%) iii. Less common in boys and men with females being nine times more likely to develop the disorder (e.g., 9 to 1 females to males) c. Adolescence (e.g., the typical time period for the onset of Anorexia Nervosa, but there has been cases of children and older adults suffering from just as severe cases) d. At-risk Populations (e.g., segments of the population where emphasis is placed on body shape and weight) i. Actors, dancers, models, athletes, etc. e. Continued low BMI’s even after recovery from Anorexia Nervosa f. Osteoporosis (e.g., decreased bone density or “brittle bones”) g. Can cause difficulties with fertility and childbirth h. Course of AN: includes periods of relapse, remission, and crossover into BN i. Mortality i. Highest death rate for any psychiatric disorder, 10.5 times more likely ii. Causes (e.g., death and suicide) 3. Personality and Anorexia Nervosa a. Perfectionism (e.g., set high standards for themselves) b. Obsessionality (e.g., repeated thoughts) c. Neuroticism (e.g., being hypersensitive, and worrying excessively without the ability to shake things off)
