Assessment of

Gambling and eating disorders


Eating disorders overview l.jpg
Eating Disorders: Overview

  • Eating controlled by factors including appetite, food, family, peer, and cultural practices, and attempts at voluntary control

  • Dieting to a body weight leaner than needed for health is highly promoted by current fashion trends, sales campaigns for special foods, and in some activities and professions

  • Eating disorders involve serious disturbances in eating behavior, such as extreme and unhealthy reduction of food intake or severe overeating, as well as feelings of distress or extreme concern about body shape or weight.

  • Eating disorders are not due to a failure of will or behavior; rather, they are real, treatable medical illnesses in which maladaptive patterns of eating take on a life of their own.

  • Main types are anorexia nervosa and bulimia nervosa


Eating disorders overview 2 l.jpg
Eating Disorders: Overview 2

  • Several family and twin studies are suggestive of a high heritability of anorexia and bulimia and researchers are searching for genes that confer susceptibility to these disorders

  • Scientists suspect that multiple genes may interact with environmental and other factors to increase the risk of developing these illnesses. Identification of susceptibility genes will permit the development of improved treatments for eating disorders


Eating disorders prevalence l.jpg
Eating Disorders: Prevalence

  • Frequently develop during adolescence or early adulthood, but can occur during childhood or later in adulthood

  • Approximately 1% of adolescent girls develop anorexia nervosa.

  • Approximately 2-3% of young women develop bulimia nervosa.

  • Two percent of adults suffer from binge eating disorder.

  • 90% of those with eating disorders are adolescent & young women.

  • Bulimia is as high as 15% in college aged women.

  • Although the common perception is that eating disorders are most prevalent among white, upper middle class young women, recent research indicates that of those who suffer from eating disorders:

    • 1 in 5 are poor

    • 1 in 4 are non-white

    • teenagers with asthma, attention deficit disorder, diabetes, and other chronic illnesses are reported to experience eating disorders 2 to 4 times more often


Eating disorders and males l.jpg
Eating Disorders and Males

  • 5-10% of eating disorders occur among males

  • Men more frequently use excessive and obsessive exercise and body-building prior to and during their eating disorder

  • Issues relating to sexuality and gender identity are sometimes associated with male eating disorders and there appears to be a higher rate of eating disorders among gay males

  • Men may be less likely to seek treatment for an eating disorder because of the social stigma of have a problem that has generally been perceived as a "woman's problem."

  • The signs, symptoms and treatment needs of eating disorders in males are similar to those of women


Anorexia prevalence l.jpg
Anorexia: Prevalence

  • Onset is usually in adolescence and affects females 10:1 over males. Prevalence in young women is up to 1%

  • Some will have episodes of binge eating or purging. Anorexia is a life-threatening disorder, with mortality over 10%

  • An estimated 0.5 to 3.7 percent of females suffer from anorexia nervosa in their lifetime

      • eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances

      • a sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating) 


    Bulimia diagnosis symptom 2 l.jpg
    Bulimia: DiagnosisSymptom 2

    • Recurrent inappropriate compensatory behavior in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, enemas, or other medications; fasting; or excessive exercise.

    • The binge eating and inappropriate compensatory behaviors both occur, on average, at least twice a week for 3 months.

    • Self-evaluation is unduly influenced by body shape and weight. 


    Bulimia diagnosis symptom 5 l.jpg

    Binge Eating Disorder: Overview

    • A newly recognized eating disorder characterized by frequent episodes of uncontrolled overeating.

      • People who struggle with binge eating disorder can be of normal or heavier than average weight.

      • Many people who suffer from binge eating disorder have a history of depression (NIH, 1993).
