Eating Disorders
This is an excerpt from the paper...
Eating disorders such as anorexia nervosa (AN) became prevalent in Western societies by the late 1960s (Polivy & Herman,á2002). Females from middle- and upper-class families were literally starving themselves to death. By the next decade bulimia nervosa (BN) had been recognized as a disorder (Polivy & Herman,á2002). AN patients are characterized by a refusal to eat or eat much. BN patients engage in binge eating and purging (Polivy, 2002). Diagnostic and Statistical Manual of Mental Disorders (fourth edition) criteria for AN includes a body weight at a level less than 85% of normal weight for age and height, intense fear of fatness, and disturbed experience of body weight or shape. Criteria for BN include recurrent episodes of both binge eating and compensatory behaviors such as purging, fasting, or exercising to prevent weight gain (Polivy, 2002). Polivy (2002) reported that the incidence of both disorders has increased over the last 50 years, with prevalence rates estimated to range from 3% to 10% of at-risk females between ages 15 and 29 years. BN patients outnumber AN patients by two to one. Polivy and Herman (2002) stated that while anorexia and bulimia are a current focus of researchers, a clear understanding of the causes of the disorders, factors predicting the development of the disorders, and methods to prevent and treat the disorders are lacking. This research explores the relationship between malad

shape, heterosexual males reported the lowest levels, and gays fell in between and lesbians had less concern regarding physical appearance, compared to heterosexual women or gay males. Over concern with body size or shape was the strongest predictor of eating disorder symptoms.
Course of Eating Disorders
Quadflieg and Fichterá(2003) reported the course and outcome of bulimia nervosa and anorexia nervosa. Mortality rates in BN are lower than in AN. Short-term course and outcome are more understood for both disorders, however, high rates of chronicity in AN and BN have been found. Studies regarding AN course are more prevalent and there is a lack of studies regarding long-term outcomes of BN. A review of previous studies demonstrated that BN long-term outcomes include relapse and chronic problems with social and sexual impairment. However sexuality and social adjustment are found to normalize in many bulimic females over time.
Severity of symptoms predicts a less positive outcome in BN and a history of AN has not been shown to be relevant to outcomes of BN. Low body weight is a negative predictor for AN and high past body weight with fluctuations of body weight have also been shown to be negative predictors for AN. F
