The Development of Eating Disorders Dissertation

The Development of Eating Disorders - Dissertation Example Exploring the development of eating disorders, both on an individual and societal level is also important in such a study, and thus this paper will discuss how Westernization and eating disorder prevalence exhibit positive correlation in the literature. Body image dissatisfaction is also an important factor in the development of eating disorders and as such information has been gathered from different cultures to illustrate the link, again providing more evidence for a sociological basis for anorexia nervosa, bulimia nervosa and binge eating disorder development in individuals. The conclusion of this paper was that the media, particularly the internet, plays a significant role in the development of the eating disorder, particularly in different social and cultural groups of people.

Anorexia Nervosa Anorexia nervosa is an eating disorder that is identified in an individual who refuses to maintain a healthy body weight and has an excessive fear of weight gain (Barker, 2003, p98). AN is associated with, more so than with other eating disorders, body image dissatisfaction and a distorted self-image (Rosen, Reiter & Orosan, 1995, p78). AN patients can also display behaviors associated with BN such as purging, but are diagnostically anorexic due to maintaining a weight below 85% of what is considered healthy and three consecutive months of amenorrhea (Polivy & Herman, 2002, p188). The average age of onset for AN is 17 (Barker, 2003, p98) although studies show this is becoming lower with time (Favaro et al., 2009). Bulimia Nervosa Bulimia nervosa is characterized by food restriction, as in AN, interspersed with short periods of overeating (also known a s binge eating) that results in feelings of guilt, low self-esteem or panic. These periods of overeating are often followed by purging mechanisms such as purposeful vomiting, laxative use or excessive exercise (Barker, 2003, p102).
