Activity and Eating Disorders
DSM-III-R (APA, 1987) subdivides eating disorders into: 1) Anorexia Nervosa, 2) Bulimia Nervosa, 3) Pica, and 4) Rumination Disorder of Infancy. The first two disorders are considered to be related by DSM-III-R and will be treated as such below. Obesity is not even listed in the index of DSM-III-R let alone considered as an eating disorder but is covered in this chapter for two reasons. First, obesity represents an excess of energy consumption over expenditure whereas anorexia involves an excess of energy expenditure over consumption. Second, there is no better place for the topic of obesity and its relationship to activity in this book.
